(InfoWorld) - Intel has tied with three large Indian PC vendors to assemble the Classmate PC, a PC specially designed for schools. The three vendors -- HCL Infosystems, Wipro, and Zenith Computers -- will start shipping the product to Indian schools next month.
The Classmate PC will be sold only to schools, and not through retail channels to consumers, John McClure, Intel's director for marketing in South Asia said on Monday. The Classmate PC has been specially designed to work in a networked classroom environment, and comes with software and features that give the teacher in the classroom control over the dissemination of content to students' PCs, he said.
The Classmate PC, for example, does not have a hard disk. Instead it contains up to 2GB of NAND flash memory. Most of the content will reside on the teacher's PC, McClure said.
Intel's manufacturering partners, such as HCL, Wipro, and Zenith, will team with content providers, education services providers, and system integrators to deploy the Classmate PCs in schools.
The PC, which can run both Linux and Windows operating systems, is powered by a 900MHz Intel Celeron mobile processor, and comes with Wi-Fi and Ethernet connectivity, Intel said. It has a 7-inch LCD (liquid crystal display) screen, and an option of 256MB or 512MB of RAM, Intel said. The device weighs less than 1.45 kg and comes with a six-cell lithium-ion battery promising three to four hours use, the company said.
The introduction of the Classmate PC follows pilots of the product by Intel in some schools in the country.
The price of the product with the control software will be 18,000 Indian Rupees ($450), with the education software and Wi-Fi connectivity available at extra cost.
That is a high price by Indian standards, prompting Intel to target the device in the first phase at private schools, rather than government-run schools that typically run on shoe-string budgets. While well-funded private schools may deploy the computers across the school, at some other private schools, it is more likely that the school will introduce the PCs initially in one class, such as the science class, according to McClure. In another rollout scenario, schools may deploy a few in each class, and assign each PC to a group of students, he said.
Intel expects some of its partners to offer schools the option to pay for the PCs on a monthly fee per student, McClure said.
The Classmate PC is also being rolled out in Nigeria and Brazil, McClure said.
Intel plans to introduce new models of the Classmate PC by the end of this year or early next year, targeted at higher education and professional schools like nursing schools, he said. These models may have some modifications in features, including large hard disk drives, to suit the usage models envisaged, McClure said.
Intel is not targeting the Classmate PCs at government-run schools in India, both because of their cost, and also because most of these schools are still behind in technology adoption. For these schools, Intel is donating about 10,000 PCs over the next three to five years, and is also training teachers on the use of computers. A number of Intel programs, including one called the Community PC, which offers a shared PC to local communities, aim to bridge the digital divide for this segment of the population, McClure said.
Intel announced earlier this month that it has joined the One Laptop Per Child (OLPC) initiative. The nonprofit project aims to equip children in developing countries with specially designed low-cost notebooks powered by chips from Intel's rival Advanced Micro Devices (AMD).
In India, however, the OLPC is a nonstarter, with the Indian government deciding not to adopt it because it does not provide for control by teachers, among other reasons. |

Critical vulnerabilities in common PC software, including both applications and operating systems, continue to grow in number and stand as the leading cause for concern in the IT security landscape today, according to training experts at the SANS Institute.Holes in so-called client-side applications, including Web browsers, e-mail clients, productivity suites, and media players, have become particularly worrisome over the last year, according to SANS, which highlighted the issue as part of its annual report on the top 20 Internet security risks for 2007.As hackers have shifted their attention further away from operating system flaws and drilled down to applications-layer vulnerabilities they have found a seemingly endless wealth of possibilities for infecting PCs with everything from spyware to botnet programs, SANS researchers contend.Unless something can be done to improve software developers' coding habits or better test popular applications for such issues before they land on end-users' machines, attackers will be able to continue their successful assaults against enterprise networks and devices for the foreseeable future, said Rohit Dhamankar, project manager for the Top 20 report at SANS and a senior manager of security research for TippingPoint.?"There's just been such a dramatic rise in the numbers of vulnerabilities found in applications like Internet Explorer and Microsoft Office and a number of media players that attackers are having their way," said Dhamankar. "Enterprises are bolstering security, but desktop users still pose a massive risk if they can download anything they want from the Web; the attacks are also growing in sophistication to the extent that many can defeat antivirus and other security systems primarily by obfuscating their code."Some of the most powerful tools that hackers have adopted in hunting for potential targets are the same industrial-strength applications fuzzing tools that software vendors themselves are using to search for holes in their products, said the expert.Enterprises could do themselves a favor by enforcing stricter policies that dictate the types of applications that end-users are allowed to put on their work machines and using technical means to ensure that those rules are being followed, Dhamankar said.Other SANS researchers noted that while companies may not want to tell end-users that they cannot utilize media players, messaging clients, and other applications that have moved into the business world from the consumer sector, they could help themselves out by limiting the variety of client-side applications that people may choose from."IT departments can't focus on all the applications of the world, but they can choose several and keep their eye on those while allowing end-users some freedom," said Amol Sarwate, research manager at Qualys who studies vulnerability patterns for SANS. "What companies need to do is enforce standards for applications usage and utilize technical means to block unwanted software, devices, and even wireless access points."While many businesses have already realized that they need to shift more of their efforts toward defending client-side vulnerabilities, most have failed to embrace a proactive approach versus simply keeping track of publicly-reported flaws and patching those issues said Sarwate.Enterprises need to think about future security issues
It will be particularly important for firms to examine the additional security issues that will be introduced in the coming years with broader adoption of technologies including VoIP (Voice over IP), according to the expert."The key is for people to start thinking ahead of these client-side vulnerabilities to understand what the next big thing may be. Things like VoIP need to be examined for their security implications," said Sarwate. "Many companies are already adopting these tools because of all the advantages they offer, but there will be many attacks carried out against these systems as well."Among the advice that SANS is offering organizations hoping to improve their client-side security coverage is to mandate secure configurations at installation time for all applications, to constantly verify patching and upgrading of both applications and system software, to scan for new vulnerabilities frequently, and to keep their security systems up to date.Other leading areas of concern highlighted by SANS in its report included critical vulnerabilities in Web applications that allow for cross-site scripting attacks or for computers to be otherwise compromised simply by pointing their browsers at poisoned URLs."Gullible, busy, accommodating computer users," including executives, IT staff, and others with privileged access also remain a major weak point for enterprise security, according to SANS, as these seemingly more seasoned users of computers and software are still falling for increasingly targeted spear-phishing campaigns in large numbers.One of the best ways to educate users about the problem is for organizations to create fake spear-phishing threats and send them out to internal users to determine which individuals might be most likely to fall for the schemes and follow up with additional training, the group said.Critical vulnerabilities in the software and systems that provide the operating environment and primary services to computer users, or server-side software, remain another area of leading concern, according to SANS.Problems in Microsoft Windows services, Unix and Mac OS services, back-up and AV programs, management servers, database software, and VoIP technologies in particular are proving troublesome, according to the report.Many of those issues can be addressed by following the same advice offered for solving client-side vulnerabilities, SANS said in the research. |

Memory maker Micron Technology on Wednesday introduced a line of solid-state drives (SSDs) and said it would plug the technology into portable storage devices by mid- to end 2008.Micron's new RealSSD hard drive, announced at an event in San Francisco, will come in sizes of 1.8 inches and 2.5 inches with storage capacities of 32GB and 64GB. Micron also announced embedded SSD modules for blade servers with storage capacities of 1GB to 8GB.Purported by many to be the future replacement of hard drives, the growth of SSDs has been stymied by high pricing, longevity, and storage issues. However, the power-efficient and ruggedness of SSDs may attract users, said Dean Klein, vice president of memory system development at Micron.RealSSD is 50 percent lighter than standard hard drives, and at under 2 watts of power consumption, the drives will be ideal for laptops, Klein said. The drives also support the SATA II interface, a standard typically used to connect hard drives to computer systems.With no moving parts, RealSSD drives also have a rugged design and store data reliably. They handle vibrations and resist shock better than rotating media, Klein said.Despite multiple advantages, SSDs may not replace hard drives as storage devices in the near future, he said. SSD technology is under development, and some markets are sensitive to price-per-gigabyte of SSDs, Klein said.SSDs currently cost between $7 and $10 per gigabyte, making them much more expensive than hard drives, which cost $0.20 to $0.30 per gigabyte, according to data from research firm iSuppli.Initial consumers for RealSSD could be OEMs or enterprises, which look for reliability and high data throughput, and laptop consumers, which require portability and power efficiency, Klein said.RealSSD drives could reach consumers in the form of portable storage devices or ExpressCards by mid- to end 2008, depending on consumer demand, Mark Adams, Micron's vice president of digital media said in an interview. An ExpressCard fits in a laptop's PCMCIA slot.Sending SSDs to consumers immediately is questionable as the emerging technology hasn't proven itself yet, Adams said. There is a risk in being first-to-market if the product doesn't sell, which will build up unnecessary inventory of SSDs. Instead, Micron will try to get feedback from OEMs that include SSDs in their products and develop devices accordingly, Adams said.Micron sells portable consumer storage devices through Lexar Media, which it acquired last year.There are already a few vendors that include SSDs in their hardware. Aurora, a gaming systems manufacturer, includes them in its Area-51 ALX and Aurora ALX desktop PCs, and Toshiba includes SSDs in its laptops. |

Micron Technology plunged headfirst into the nascent solid state drive marketplace Wednesday with the unveiling of its RealSSD family of storage devices.The RealSSD portfolio features serial ATA II-enabled 1.8-in. and 2.5-in. solid state drives in 32GB and 64GB capacities. Early next year, the company will start mass producing the drives, which are currently being "sampled," said Dean Klein, vice president of memory system development at Boise, Idaho-based Micron.Micron's RealSSD drives, noted Klein, require less than 2 watts of power during active mode and are about 50 percent lighter than hard disk drives of similar capacities. The devices do not require a SATA bridge chip but rather rely on a single-chip controller (optimized for four-channel control of NAND flash) directly targeting the solid state drive application, he added.The new RealSSD line also includes the Embedded USB and Module products. The RealSSD Embedded USB can be plugged into a PC or blade server system to provide operating system storage and boot capabilities via a USB 2.0 interface. The RealSSD Module is a SATA-enabled solid state drive for server-based applications that measures 25mm high by 133.5mm long and less than 4mm thick.Klein acknowledged that adoption of solid state drives for corporate users has been very slow, mostly because of the technology's high price tag. However, he predicted that declining prices of NAND flash technology and the inevitable development of applications for solid state systems will accelerate demand."Technology is going to make [solid state] real. The cost of the NAND components will be a large determining factor in terms of acceptance," said Klein. "Even if we could bring speed of light performance to these devices, there's a lot of applications that still won't take them because the cost is too high or the density isn't high enough."Of the many first-generation solid state drive devices currently available, Klein remarked, "benchmarks have proven them to be fairly lame in terms of performance." Going a step further, he panned BitMicro Networks' 1.6TB solid state drive unveiled this month as a "pricey piece of art." Samsung Electronics and SanDisk are considered two established leaders currently providing solid state drive offerings, analysts noted.Although initially focused on providing solid state drives for the notebook audience -- a natural fit, said Klein, because solid state is lightweight, and offers power savings and a small size -- Micron does have interest in examining larger-capacity solid state products for the desktop and enterprise industry.Jeff Janukowicz, an analyst at IDC, said his IT research firm has forecast that demand for solid state technology will "substantially" increase over the next few years. An IDC report released in July predicted that sales of solid state drives will grow from $373 million in 2006 to a total of $5.4 billion in 2011.While notebook computing will fuel solid state adoption, Janukowicz said he expects the need for improved performance and specialized applications in servers, blade servers, and enterprise storage systems to attract growing solid state interest over time.Janukowicz said Micron's decision to debut an entire family of solid state products with RealSSD and its established NAND and flash memory expertise could prove to be a key differentiator with OEMs. But much work still needs to be done, he noted."Micron needs to work well with PC OEMs that deliver solutions acceptable for the PC market," he said. "The challenge there is [a traditional] usage model of using hard disks in notebook PCs. There is a bit of education process in terms of using solid state disks as primary storage in network computing that needs to take place."Computerworld is an InfoWorld affiliate |
