What are SANs and NAS?

Throughout the history of computing, people have wanted to share computing resources. The Burroughs Corporation had this in mind in 1961 when they developed multiprogramming and virtual memory. Shugart Associates felt that people would be interested in a way to easily use and share disk devices. That's why they defined the Shugart Associates System Interface (SASI) in 1979. This, of course, was the predecessor to SCSI - the Small Computer System Interface. In the early 1980s, a team of engineers at Sun Microsystems felt that people needed a better way to share files, so they developed NFS. Sun released it to the public in 1984, and it became the Unix community's prevalent method of sharing filesystems. Also in 1984, Sytec developed NetBIOS for IBM; NetBIOS would become the foundation for the SMB protocol that would ultimately become CIFS, the predominant method of sharing files in a Windows environment.

Neither storage area networks (SANs) nor network attached storage (NAS) are new concepts. SANs are simply the next evolution of SCSI, and NAS is the next evolution of NFS and CIFS.

History

As mentioned earlier, SCSI has its origins in SASI, defined by Shugart Associates in 1979. In 1981, Shugart and NCR joined forces to better document SASI and to add features from another interface developed by NCR. In 1982, the ANSI task group X3T9.3 drafted a formal proposal for the Small Computer System Interface (SCSI), which was to be based on SASI. After work by many companies and many people, SCSI became a formal ANSI standard in 1986. Shortly thereafter, work began on SCSI-2, which incorporated the Common Command Set into SCSI, as well as other enhancements. It was approved in July 1990. Although SCSI-2 became the de facto interface between storage devices and small to midrange computing devices, not everyone felt that traditional SCSI was a good idea. This was due to the physical and electrical characteristics of copper-based parallel SCSI cables. (SCSI systems based on such cables are now referred to as parallel SCSI, because the SCSI signals are carried across dozens of pairs of conductors in parallel.) Although SCSI has come a long way since 1990, the following limitations still apply to parallel SCSI:
  • Parallel SCSI is limited to 16 devices on a bus.
  • It's possible, but not usually practical, to connect two computing devices to the same storage device with parallel SCSI.
  • Due to cross talk between the individual conductors in a multiconductor parallel SCSI cable, as well as electrical interference from external sources, parallel SCSI has cable length limitations. Although this limitation has been somewhat overcome by SCSI-to-fiber-to-SCSI conversion boxes, these boxes aren't supported by many software and hardware vendors.
  • It's also important to note that each device added to a SCSI chain shortens its total possible length.

Nothing but net(work): Why you need one

Wireless home networking isn't just about linking computers to the Internet. Although that task is important - nay, critical - in today's network-focused environment, it's not the whole enchilada. Of the many benefits of having wireless in the home, most have one thing in common: sharing. When you connect the computers in your home through a network, you can share files, printers, scanners and high-speed Internet connections between them. In addition, you can play multiuser games over your network, access public wireless networks while you're away from home, check wireless cameras, use Internet Voice over IP (VoIP) services, or even enjoy your MP3s from your home stereo system while you're at work - really!

Reading Wireless Home Networking For Dummies, 3rd Edition, helps you understand how to create a whole-home wireless network to reach the nooks and crannies of your home. The big initial reason that people have wanted to put wireless networks in their homes has been to 'unwire' their PCs, especially laptops, to enable more freedom of access in the home. But just about every major consumer goods manufacturer is hard at work wirelessly enabling its devices so that they too can talk to other devices in the home - you can find home theater receivers, music players, and even flat-panel TVs with wireless capabilities built right in.

People go with wireless networking for:
  • File sharing
  • Internet connection sharing
  • Printer and peripheral sharing

Introduction to Wireless Networking

Over the past 5 years, the world has become increasingly mobile. As a result, traditional ways of networking the world have proven inadequate to meet the challenges posed by our new collective lifestyle. If users must be connected to a network by physical cables, their movement is dramatically reduced. Wireless connectivity, however, poses no such restriction and allows a great deal more free movement on the part of the network user. As a result, wireless technologies are encroaching on the traditional realm of 'fixed' or 'wired' networks. This change is obvious to anybody who drives on a regular basis. One of the 'life and death' challenges to those of us who drive on a regular basis is the daily gauntlet of erratically driven cars containing mobile phone users in the driver's seat.

Wireless connectivity for voice telephony has created a whole new industry. Adding mobile connectivity into the mix for telephony has had profound influences on the business of delivering voice calls because callers could be connected to people, not devices. We are on the cusp of an equally profound change in computer networking. Wireless telephony has been successful because it enables people to connect with each other regardless of location. New technologies targeted at computer networks promise to do the same for Internet connectivity. The most successful wireless data networking technology this far has been 802.11.

Transforming materials

Many thousands of years ago, people began to find ways of changing the simple materials they found around them into more useful forms that could help them survive in a hostile world. Soft clay was available everywhere and easy to shape, but it was fragile. Transformed by fire, it became the hard, waterproof body of a cooking pot or storage jar. Even common sand can be transformed by heating it with other substances to make the smooth, transparent material called glass. Other rocks yield strong, tough metals when heated with the right materials. All of these processes require energy, often in the form of heat. And all of them are still in use today, although they now take place on a huge scale, using much more energy than in the past.

What is technology?

Technology is the science & art of making and using things. Human beings are uniquely able to turn the materials of the natural world into tools and machines that can help them live. Although other animals can make things and use tools - the otter uses rocks to break open shell - the way they do this hardly ever changes. Human technology is different: people are able to see new needs, find new ways of meeting them, and spot the value of accidental discoveries. The discovery of fire, for example, and its ability to transform clay into pottery or rocks into metals, made the modern world possible. Over the last few hundred years, scientists have found out why materials and machines behave the way we do. Using this knowledge, old materials have been improved, new materials invented, and science and mathematics brought to bear on products as different as swimwear and aircraft. Making things starts with design - working out what is needed and how to provide it. Designers now have a vast range of materials, methods, and components with which to realize their ideas, and today much of their work can be done by computers. But producing something that works well, costs little, and appeals to its users remains a truly human art.

Antitrust Inquiry for IBM

The Justice Department has started a preliminary investigation into whether I.B.M. has abused its monopoly position in the market for mainframe computers, which remain vital to many of the world’s largest businesses. This month, antitrust regulators at the Justice Department began seeking information about I.B.M.’s business practices from companies that compete with I.B.M. in the market for large computer hardware and software, people who had been contacted in the inquiry said.

The requests for information followed a complaint filed by the Computer and Communications Industry Association, a trade group with a history of involvement in antitrust disputes. The organization, which is backed by I.B.M. competitors like Microsoft and Oracle, contends that I.B.M. stymied competition in the mainframe market and blocked efforts by competitors and potential partners to license I.B.M.’s software.

The complaint follows similar legal action taken by T3 Technologies against I.B.M.

T3, a small company that resold mainframelike computers, filed an antitrust complaint against I.B.M. in January in Europe. T3 also filed a civil suit against I.B.M. in the United States. Last week a federal district judge in New York dismissed that case. T3 said it planned to appeal.

Steven Friedman, the president of T3, said he had received a formal request for information from the Justice Department about I.B.M.’s actions in the mainframe market. “They asked for a very broad set of documents and information,” he said.

Edward J. Black, the chief executive of the Computer and Communications Industry Association, confirmed that it had filed a complaint against I.B.M. with the Justice Department and that investigators had contacted some members.

A Justice Department spokeswoman declined to comment.

The inquiry is the early stages and may not result in charges against I.B.M. The last time federal regulators pursued an antitrust suit against I.B.M. in the mainframe market, the result was a humbling setback for the department when the Reagan administration dropped the case in 1982, after 13 years.

In a statement on Wednesday, I.B.M. cited the judge’s ruling last week against T3 and said, “We continue to believe there is no merit to T3’s claims.”

“We understand the Department of Justice has asked T3 for documents from the litigation,” I.B.M. said. “I.B.M. intends to cooperate with any inquiries from the Department of Justice.”

While sometimes called the dinosaurs of computing, mainframes continue to play a vital role in business. The systems are estimated to handle 50 billion transactions a day in such areas as automated teller machines, health records and accounting.

Mainframes are also important to I.B.M. About 25 percent of its $104 billion in annual revenue comes from the sale of mainframes and associated products like storage systems, software and services, said A. M. Sacconaghi, a securities analyst with Sanford C. Bernstein.

Historically, I.B.M. has faced off against competitors in the mainframe market. Past rivals, including Amdahl, Hitachi and Fujitsu, built computers that could run I.B.M. software, which was a standard for mainframes.

Most rivals abandoned their mainframe systems when I.B.M. developed more advanced chips for its machines, in part because of the cost of moving to the new chips.

More recently, smaller companies and even individuals have worked to create software to mimic mainframe functions on lower-cost, mainstream computer servers.

One start-up called Platform Solutions had modest success with this approach earlier this decade and drew the interest of Hewlett-Packard, which held discussions about buying the company.

I.B.M., however, declined to license its mainframe software to Platform and sued the company. Last year, I.B.M. acquired Platform for $150 million and discontinued the company’s computer systems.

I.B.M.’s decision not to license its mainframe software has been at the heart of the antitrust complaints against it. In addition, competitors have argued that I.B.M. has stepped up aggressive tactics to block them from selling products that can lower the cost of mainframe technology.

But I.B.M.’s opposition to licensing its technology to outsiders is not enough to build a successful government antitrust case, said Andrew I. Gavil, a law professor at Howard University. More likely, Professor Gavil said, the Justice Department is investigating to see if I.B.M. is engaged in other tactics that might be anticompetitive.

In the ruling in the private case last week, Judge Lewis A. Kaplan of Federal District Court in Manhattan found that I.B.M. had invested heavily in its modern mainframe technology and its decision not to license it “does not constitute anticompetitive conduct.”

The technology industry has undergone an accelerating wave of consolidation as companies like Hewlett-Packard, Oracle, EMC and Dell have made large acquisitions. The deals reflect a desire by large technology companies to offer a wider range of hardware, software and services so that customers see them as one-stop shops.

Analysts contend that I.B.M.’s dominance in the mainframe market gives it a major advantage because it deals with its customers’ most confidential information. They also say that I.B.M.’s practices have resulted in higher costs for customers.

In E-Books, It’s an Army vs. Google

SAN FRANCISCO — Whenever it can, Google likes to have programmers solve its problems. But now it faces a dispute that even its ranks of lawyers and lobbyists are finding hard to smooth over.

A broad array of authors, academics, librarians and public interest groups are fighting the company’s plan to create a huge digital library and bookstore. Their complaints reached the ears of regulators at the Justice Department, which last month helped derail the plan by asking a court to reject the class-action settlement that spawned it.

That request led to a last-minute decision by Google and its partners, the Authors Guild and the Association of American Publishers, to redraft the agreement. A federal court hearing in New York on Wednesday will shed light on their progress.

Some analysts say the broad-based opposition to Google’s lofty plans was unprecedented and a harbinger of the intense scrutiny the company’s ambitious agenda will face.

“This was the first issue through which Google’s power became clearly articulated to the public,” said Siva Vaidhyanathan, associate professor of media studies and law at the University of Virginia. “All sorts of people — writers, researchers, librarians, academics and readers — really feel they have a stake in the world of books.”

Google expressed confidence that a new agreement that could win court approval might be ready within weeks. “I don’t think we need a lot of time,” said David Drummond, Google’s chief legal officer.

This is not the first time Google’s ambitions have collided with the Justice Department. Last year, after advertisers and competitors argued that a planned ad deal with Yahoo would harm competition, the department said it would try to block the partnership in court. Google chose to abandon the deal rather than fight.

This time, the department’s lawyers heard from Google rivals like Microsoft. But they also heard complaints from a much broader group, many of whom shared the same fear: that the deal would allow Google, the 800-pound gorilla of digital information, to bulk up even more and lock out competitors in the nascent digital book market.

In a recent order, the judge who will have to approve or reject the settlement remarked on the number and breadth of objections the court had received. “Clearly, fair concerns have been raised,” wrote Judge Denny Chin of the United States District Court for the Southern District of New York.

The Justice Department told the court that it hoped the parties would be able to modify the agreement to address antitrust, copyright and class-action problems, while preserving some of its benefits.

Some experts say that even if a modified deal is approved, the dispute portends the kind of suspicion that Google’s plans will likely face.

“Google will have continuous challenges to major initiatives around consumer choice, security and trust, privacy,” said David Yoffie, a professor at the Harvard Business School. “This will never stop. It will be a question of how well Google builds coalitions and lays the groundwork before they establish a fait accompli in a particular area.”

Google’s plan emerged from a sweeping settlement of a class-action lawsuit filed by authors and publishers in 2005 over the company’s effort to digitize books from major libraries. Google and its allies hailed the agreement as a public good: millions of out-of-print books would become widely available, unlocking vast swaths of human knowledge, while giving authors new ways to earn money from digital copies of their works.

While Google’s corporate rivals fanned the flames of opposition, much of the resistance to the deal began in the confines of academia and spread gradually. In the end, more than 350 individuals, companies, nonprofit groups, academics, library associations, overseas publishers, states and even foreign governments lodged complaints in court against the agreement, in whole or in part. They outnumbered the filings in support of the deal by about 10 to 1.

Many scholars initially sided with Google in 2004 when its scanning project, originally designed to create a kind of universal card catalog, drew lawsuits from the Authors Guild and the Association of American Publishers. But the settlement transformed Google’s plan into something far more ambitious.

Online users of Google’s digital library and store would get free access to 20 percent of any book and be able to pay to read the rest. Every library in America would be able to offer free, full access to Google’s library at one terminal. And universities would be able to purchase access to the entire collection. Revenue would be split among Google, authors and publishers.

Even before the agreement was signed last October, however, opposition began to brew. Harvard University, which along with a few other libraries had been invited to participate in some of the negotiations, withdrew. A few months later, Robert Darnton, head of the university’s library system, wrote an impassioned attack on the deal in The New York Review of Books.

Around the same time, Pamela Samuelson, a respected Internet law and copyright expert at the University of California, Berkeley, convened a meeting of concerned scholars who began spreading the word at universities.

At a conference at Columbia Law School in March, the outlines of the opposition began to emerge. Critics said the deal would grant Google quasi-exclusive rights to commercialize millions of orphan works, books whose rights holders are unknown or cannot be found. That would make it hard to compete with, potentially leaving Google free to raise prices.

Others said the deal turned copyright law on its head by letting Google profit from millions of books unless authors objected. Librarians grew concerned that Google wouldn’t adequately protect their patrons’ privacy.

Gail Steinbeck, the daughter-in-law of John Steinbeck, received notice of the settlement shortly before a May deadline for authors to opt out. She thought most authors would not understand it.

“When I saw this come through, just a few weeks before the deadline, I flipped out,” said Ms. Steinbeck, who along with her husband has been involved in a legal fight over the rights to some of John Steinbeck’s works.

Ms. Steinbeck quickly sent a letter to several influential authors laying out her fears. “It would be a shame to have to go back to Congress and/or the courts in a few years to ask them to split up a monopoly, when we have the chance to stop it in its tracks right now,” she wrote.

As a result, a group of authors that included the musician Arlo Guthrie asked the court for a four-month extension, which was granted. The delay proved crucial, as it gave time for opponents to get organized, leading to a veritable deluge of last-minute filings.

Lawrence Lessig, an Internet scholar and professor at Harvard Law School, said Google’s belief that its actions and motives were misunderstood reminded him of a frustration that permeated Microsoft in the 1990s.

“I’ve seen these big powerful companies filled with people who drank the Kool-Aid,” said Professor Lessig, who initially supported Google’s scanning but later came to oppose the settlement. “I really get the sense in which these people feel they are doing good. But I am always surprised by their failure to recognize how they will be perceived outside.”

Mr. Drummond said Google anticipated that a deal so sweeping would generate criticism. He said support for it was far broader than the opposition, noting that the guild and the publishers association represented a large portion of the American book industry.

“The benefits far outweigh any of these criticisms that are being made, many of which are quite theoretical,” Mr. Drummond said. “We have a good process now for taking into account some of the objections.” He added: “The fact that there are some critics doesn’t mean you should be paralyzed and not do something that provides value.”

Soon, Bloggers Must Give Full Disclosure

FOR nearly three decades, the Federal Trade Commission’s rules regarding the relationships between advertisers and product reviewers and endorsers were deemed adequate. Then came the age of blogging and social media.

On Monday, the F.T.C. said it would revise rules about endorsements and testimonials in advertising that had been in place since 1980. The new regulations are aimed at the rapidly shifting new-media world and how advertisers are using bloggers and social media sites like Facebook and Twitter to pitch their wares.

The F.T.C. said that beginning on Dec. 1, bloggers who review products must disclose any connection with advertisers, including, in most cases, the receipt of free products and whether or not they were paid in any way by advertisers, as occurs frequently. The new rules also take aim at celebrities, who will now need to disclose any ties to companies, should they promote products on a talk show or on Twitter. A second major change, which was not aimed specifically at bloggers or social media, was to eliminate the ability of advertisers to gush about results that differ from what is typical — for instance, from a weight loss supplement.

For bloggers who review products, this means that the days of an unimpeded flow of giveaways may be over. More broadly, the move suggests that the government is intent on bringing to bear on the Internet the same sorts of regulations that have governed other forms of media, like television or print.

“It crushes the idea that the Internet is separate from the kinds of concerns that have been attached to previous media,” said Clay Shirky, a professor at New York University.

Richard Cleland, assistant director of the division of advertising practices at the F.T.C., said: “We were looking and seeing the significance of social media marketing in the 21st century and we thought it was time to explain the principles of transparency and truth in advertising and apply them to social media marketing. Which isn’t to say that we saw a huge problem out there that was imperative to address.”

Still, sites like Twitter and Facebook, as well as blogs, have offered companies new opportunities to pitch products with endorsements that carry a veneer of authenticity because they seem to be straight from the mouth — or keyboard — of an individual consumer. In some cases, companies have set up product review blogs that appear to be independent. One such case involved Urban Nutrition, a seller of supplements, that ran Web sites like WeKnowDiets.com and GoogleDiets.com. The National Advertising Review Council, which governs the industry’s self-regulatory programs, said the sites were “formatted as independent product-review blogs.”

Jonathan Zittrain, a professor at Harvard Law School and co-founder of the Berkman Center for Internet and Society, said, “the rules are looking ahead to a quite possible future when there is a market to buy ‘authentic’ public endorsements.”

Some marketing groups fought the changes. “If a product is provided to bloggers, the F.T.C. will consider that, in most cases, to be a material connection even if the advertiser has no control over the content of the blogs,” said Linda Goldstein, a partner at Manatt Phelps & Phillips, a law firm that represents three marketing groups, the Electronic Retailing Association, the Promotion Marketing Association and the Word of Mouth Marketing Association. “In terms of the real world blogging community, that’s a seismic shift.”

Ms. Goldstein added, “We would have preferred the F.T.C. to work closer with the industry to learn how viral marketing works.”

The new guidelines were not unexpected — the commission gave notice last November that it would take up the matter. They will affect scores of bloggers who began as hobbyists only to find that companies flocked to them in search of a new way to reach consumers.

About three-and-a-half years ago Christine Young, of Lincoln, Calif., began blogging about her adventures in home schooling. It led to her current blog, FromDatesToDiapers.com, about mothers and families. The free products soon started arriving, and now hardly a day goes by without a package from Federal Express or DHL arriving at her door, she said. Mostly they are children’s products, like Nintendo Wii games, but sometimes not. She said she recently received a free pair of women’s shoes from Timberland.

Ms. Young said she had always disclosed whether or not she received a free product when writing her reviews. But companies have nothing to lose when sending off goodies: if she doesn’t like a product, she simply won’t write about it.

“I think that bloggers definitely need to be held accountable,” said Ms. Young. “I think there is a certain level of trust that bloggers have with readers, and readers deserve to know the whole truth.”

M.I.T. Taking Student Blogs to Nth Degree

CAMBRIDGE, Mass. — Cristen Chinea, a senior at M.I.T., made a confession in her blog on the college Web site.

“There’ve been several times when I felt like I didn’t really fit in at M.I.T.,” she wrote. “I nearly fell asleep during a Star Wars marathon. It wasn’t a result of sleep deprivation. I was bored out of my mind.”

Still, in other ways, Ms. Chinea feels right at home at the institute — she loves the anime club, and that her hall has its own wiki Web site and an Internet Relay for real-time messaging. As she wrote on her blog, a hallmate once told her that “M.I.T. is the closest you can get to living in the Internet,” and Ms. Chinea reported, “IT IS SO TRUE. Love. It. So. Much.”

Dozens of colleges — including Amherst, Bates, Carleton, Colby, Vassar, Wellesley and Yale — are embracing student blogs on their Web sites, seeing them as a powerful marketing tool for high school students, who these days are less interested in official messages and statistics than in first-hand narratives and direct interaction with current students.

But so far, none of the blogs match the interactivity and creativity of those of the Massachusetts Institute of Technology, where they are posted prominently on the admissions homepage, along with hundreds of responses from prospective applicants — all unedited.

Not every admissions office has been so ready to welcome uncensored student writing.

“A lot of people in admissions have not been eager for bloggers, mostly based on fears that we can’t control what people are saying,” said Jess Lord, dean of admissions at Haverford College, which posted student bloggers’ accounts of their summer activities this year, and plans to add bloggers this spring to help admitted students hear about campus life. “We’re learning, slowly, that this is how the world works, especially for high school students.”

M.I.T.’s bloggers, who are paid $10 an hour for up to four hours a week, offer thoughts on anything that might interest a prospective student. Some offer advice on the application process and the institute’s intense workload; others write about quirkier topics, like warm apple pie topped with bacon and hot caramel sauce, falling down the stairs or trying to set a world record in the game of Mattress Dominos.

Posting untouched student writing — and comments reacting to that writing — does carry some risks. Boring, sloppily written posts do nothing to burnish an institutional image, college admissions officials say, and there is always the possibility of an inflammatory or wildly negative posting.

Pomona has considered having student bloggers, but so far has felt that the risks outweigh the benefits, said Art Rodriguez, senior associate dean of admissions.

“Blogs can certainly help humanize the process,” Mr. Rodriguez said. “The flip side is that a few anxious high school students may think and worry too much about what someone wrote on their blog, and present themselves in a slightly different way than who they really are. And there’s always the concern about the political ramifications, that bloggers may open up an issue or topic that starts something negative.”

But Mr. Lord of Haverford said prospective students’ interest in the summer bloggers calmed his worries.

“High school students read the blogs, and they come in and say ‘I can’t believe Haverford students get to do such interesting things with their summers,’ ” he said. “There’s no better way for students to learn about a college than from other students.”

Many high school seniors avidly follow student blogs at the colleges they are interested in, and post comments. Luka, one of dozens responding to Ms. Chinea, for example, wrote: “I didn’t know about the anime club. I would have never guessed that people at M.I.T. are interested in anime. Oh well ... +1 on my ‘Why should I go to M.I.T.’ list.”

M.I.T.’s student bloggers said they had read the blogs when they were applying, posted comments and connected with other applicants.

“I was blogging myself, almost every day, when I was in high school, and I read the M.I.T. blogs all the time,” said Jess Kim, a senior blogger. “For me they painted a picture of what life would be like here, and that was part of why I wanted to come.”

Ben Jones, the former director of communications at M.I.T.’s admissions office, began with a single blog by a student five years ago, at the dawn of the Facebook era, and noticed high school students responding right away. “We saw very quickly that prospective students were engaging with each other and building their own community,” said Mr. Jones, who now works at Oberlin College, where he has added blogs to the Web site.

The M.I.T. student bloggers have different majors, ethnicities, residence halls and, particularly, writing styles. Some post weekly or more; others disappear for months. The bloggers are sought out as celebrities during the annual “Meet the Bloggers” session at Campus Preview Weekend.

M.I.T. chooses its bloggers through a contest, in which applicants submit samples of their writing. “The annual blogger selection is like the admissions office’s own running of the bulls,” said Dave McOwen, Mr. Jones’s successor in the admissions office, in his message inviting applications.

This year, 25 freshmen applied for four new spots, and, Mr. McOwen said, it was hard to choose.

“You want people who can communicate and who are going to be involved in different parts of campus life,” he said. “You want them to be positive, but it’s not mandatory.”

And not all posts are positive. Ms. Kim once wrote about how the resident advising system was making it impossible for her to move out of her housing — expressing enough irritation that the housing office requested that the admissions office take her post down. Officials refused, instead having the housing office post a rebuttal of her accusations; eventually, the system was changed.

But most of the blogs are exuberant, lyrical expressions of the joys of M.I.T. life, like last month’s post on returning as a sophomore:

“Something’s changed,” wrote Chris Mills. “Now you know what you’re in for, you know the sleepless nights and frustrations are never far away, but this knowledge can’t seem to remove the exhilarating smile on your face. And it’s in that masochistic moment that you realize who you are. That this is what you’re made for.”

Cisco Buys Norwegian Firm for $3 Billion

SAN FRANCISCO — Cisco Systems continued to show just how serious it is about video conferencing, announcing late Wednesday night the $3 billion acquisition of Tandberg, a Norwegian video communications company.

Cisco has sold expensive, room-sized video conferencing systems to companies that it calls TelePresence systems. Tandberg has similar technology but also sells smaller-sized, cheaper conferencing units. In addition, Tandberg has specialized software for managing video conferencing systems and for creating connections between conferencing systems that rely on different underlying technology.

“It really enables us to build out our portfolio,” said Ned Hooper, a senior vice president at Cisco.

Cisco’s corporate video conferencing products require the company to outfit a customer’s conference room with multiple, large displays, networking equipment and even special tables, chairs and wall paint. By contrast, Tandberg has a range of gear, including high-definition video systems that can sit on desks or be used with personal computers.

The all-cash deal has been recommended to Tandberg’s shareholders by that company’s directors and stands as an 11 percent premium over Tandberg’s closing price on Wednesday. Tandberg reported $809 million in revenue last year, and has close to $200 million in cash.

In recent years, Cisco, based in San Jose, Calif., has been one of the technology industry’s most aggressive companies when it comes to acquisitions. It has bought close to 40 companies over the past five years, including the $6.9 billion purchase of the set-top-box maker Scientific-Atlanta and the $2.9 billion purchase of the Web meeting software maker WebEx. Cisco also bought Pure Digital, which made the popular Flip video recorders for consumers , earlier this year for $590 million.

The acquisitions have fueled Cisco’s mission of backing products that generate more Internet traffic that in turns drives demand for the networking hardware that has long been the core of its business.

The deals have also thrust Cisco into new markets like consumer electronics, business collaboration software and computer servers where the company now finds itself in direct competition with its traditional business partners like Hewlett-Packard, Microsoft and I.B.M.

During an interview last week, Cisco’s chief executive John T. Chambers boasted that the company has managed to move into a grand total of 30 new markets through acquisitions and its own internal product development.

“We are involved in things that may shock you,” Mr. Chambers said, referring to s like smart grid technology for cities’ power systems and the construction of entertainment and networking systems for sports stadiums.

With $35 billion in cash - the highest total in the technology industry - Cisco appears set to continue with this expansion.

“You will see us move with a lot of acquisitions over the next year,” Mr. Chambers said.

Still, companies like Cisco, Dell and EMC must find ways to match the heft of H.P. and I.B.M., which have massive technology services businesses to complement their hardware and software pursuits.

Rather than acquiring a large services company, Cisco will continue to partner with independent players like Accenture and Wipro, Mr.

Chambers said.

“I think that is a more scalable, faster speed and less confrontational model,” he said.

As Cisco moves into new areas, it faces the difficult task of trying to find businesses with profits that can match those gained from its networking hardware. Cisco’s routers and switches produce 65 percent gross profit margins.

Mr. Hooper stressed that Tandberg has gross margins of 66 percent. “It fits squarely into our operating model,” he said.

Tandberg has had the most success selling video conferencing systems to large companies in North America and Europe. Cisco plans to use Tandberg’s technology to help it go after smaller companies and eventually to target consumers, Mr. Hooper said.
