All About Dell Laptops

All About Dell Laptops
Dell Inc., is an American computer hardware company based in Round Rock, Texas, Formed by Michael Dell, while he was a student at the University of Texas at Austin. He founded the company as "PC" Limited with just $1000, in his room, an off campus dorm, in 1984 to sell IBM-compatible computers built from stock components.
The company has been formed on the principle that by selling computer systems directly to the customers, it could best understand their needs and provide them the most effective computing solutions. The solutions can be for a wide range of personal computer, servers, data storages devices, network switches, personal digital assistance for software, computer peripherals and so on.
Dell Laptops computers bring the ease of convenience and high performance machine together, at affordable prices. Dell laptops bring integrated high-speed 3G connectivity and high performance in form factors, both small and large. Dell meets your need for higher performance, excellent value or a lightweight travel notebook. Dell laptops span a wide range of sizes from 12 inches to 20 inches; these are powerful but pricey laptops featuring an Intel Core Duo processor and Microsoft’s Media Center OS. The display resolutions of the dell laptops are 855/865/815 and 1400 * 1050 chipset.
The different types of laptop are
1. Ultraportables:Laptops have screens typically less than 12 inches diagonally and weigh less than 1.7kg. Their primary audience is usually business travelers who need small, lightweight laptops. Ultraportables are often very expensive and house power-saving CPUs and almost always have integrated graphics.
2. Thin-and-lights:These are the Laptops which weigh between 1.8kg and 2.8kg with a screen size of 12 or 14 inches diagonally.
3. Medium-sized laptops:These are usually having screens of 15 - 15.4 inches diagonally and weigh around 3-3.5kg.
4. Desktop replacement computers:These are powerful laptops mainly used in a fixed location and infrequently carried out due to there weight and size. They provide more space for powerful components and a big screen - usually measuring 15 inches or more for desktop replacements and often have limited battery life due to their hardware, rarely exceeding three hours.
Dell manufactures its products close to the customers. The assembling of desktop computers for the North American market takes place at Dell Laptops plants in Austin, Texas and in Winston-Salem, North Carolina with servers built in Nashville, Tennessee. Dell, Inc. assembles computers for Europe in Limerick City, Ireland. The major competitors of Dell are Apple, Hewlett-Packard/Compaq, Packard Bell, Sun Microsystems, Gateway/Emachines, Lenovo, Sony, Toshiba, and MDG Computers in Canada. Enthusiast market competition takes place with Alienware, now which is a Dell’s division- Falcon Northwest, Voodoo PC, WidowPC, Sin Systems Inc. and other manufacturers. By August 2003, Dell Laptops lowered their product prices by 22% in an attempt to generate more sales; however this disappointed shareholders, sending it shares down by 2% in late Wall-Street trading, amid fears of a sector-wide slump.
Dell Laptops Models:
Dell Inspiron : The Dell Inspiron is a laptop brand of Dell computers targeted at the consumer markets with different specification models, and its current modules are B130, E1405, E1505 and E1705. First-generation Dell Inspirion XPS and Dell Inspiration 9100, both share the same option in processors with Intel Pentium 4 HT "Prescott", RAM of DDR 400 MHz, hard-drives with Ultra-ATA 5400/7200 RPM, wireless cards, LCD screens at 15.4-inches, WXGA, WSXGA+, WUXGA, along with graphical cards of ATI Mobility, Redeon 9700 64MB/128MB. It marked XPS as an "ultimate gaming machine", and 9100 as "desktop replacement".
Inspiron e1505 : The Inspiron e1505 is a one with Core Duo PCMAG, just based on 15.4 inch widescreen and supported with 1.67GHz Intel Core Duo, 1GB DDR2 SDRAM, 80GB (5400rpm) disk, 802.11b/g, dual-layer DVD burner, and ATI Mobility Radion X1300 graphics. It is a perfect one for the people who appreciate technology on a budget. The battery only manages for about 3 hours. While ordering you have to enter a goofy of E-Value code "E1505PC", if you expect your kit to ring-up with that sub-grand price tag. Righteous pricing indeed for this full featured and powerful kit. The E1505 is available with familiar arctic-silver chassis and white edges. At a cost of 6.6 pounds, it is little lighter than the 7-pound Inspiron 6000. The keyboard is comfortable to use, and especially doesn't heat up after extensive typing, as many do. And the user will be pleased as Dell has fixed the noisy mouse buttons.
Inspiron e1705 : The Inspiron e1705 is available either with an Intel Core Duo or Solo processor, this machine features a 17-inch XGA (or WUXGA) wide-screen LCD. Options also include a Vidia GeForce Go7900 GS, ATI Radeon x1600 with 256mb of RAM or an Intel GMA 950. This model uses 533 MHz or 667 MHz of DDR2 memory. In Dell Laptops Inspiron e1705 has connectivity options in plentiful, with six USB ports, one FireWire port, a 5-in-1 card reader, and a DVI-D port for sending content to a high-end display. On the other hand, the 80GB hard drive installed in our test machine is probably not enough for an avid video editor.
Inspiron e1405 : The Inspiron e1405 is a 14 inches notebook configurable with components similar to the E1505 excluding the dedicated GPU options but a bit smaller in total size. At the time Inspiron e1405 was released, it was known for its excellent battery life with under optimum conditions exceeding five hours with a six-cell battery and over eight hours for a slightly more expensive range, along with optional nine-cell battery.
nsprion B130 : The Inspiron B130 is a budget notebook and mainly constructed in a manner to keep costs down. Its body casing is entirely plastic, no fancy aluminum or magnesium protection. The plastic used is not flimsy tough, it is actually quite sturdy. Operating of the Dell Laptops of Inspiron B130 will be easier to the user.
XPS M2010 : The XPS M2010 is the system having a 20.1 inches LCD screen with a 1680x1050 resolution and it can be transported easier than a desktop computer system, but much of XPS M2010 components are still based upon notebook technology, only in a larger format. The system weighs an astounding 18.5 lbs. It is not known to many people who would really want to carry around this with them for any extended period of time. It has base measures as 19.3 x 8.3 x 2 inches.
XPS M1210 : The Dell XPS M1210 ultramobile notebook offers superior value. It sports a revolutionary design that turns the display supports into a system handle when the system is closed. The Dell XPS M1210 model weighs just 4.37 pound with a durable magnesium alloy frame. We can add A/V package that includes an integrated webcam, video chat software, Skype Internet communication software, noise-isolation earbuds and optional embedded mobile broadband. This complete communication solution includes a built-in 1.3 mega pixel camera, an integrated omni-directional microphone and an integrated mobile broadband antenna.
XPS M1710 : The XPS M1710 designing is nearly identical to the previous model, the Dell XPS M170 and it is very similar to the more multimedia-focused Inspiron E1705. It has stylish magnesium alloy and it measures 15.5 inches wide, 11.3 inches deep and 1.6 inches thick. The XPS M1710 includes a full-size keyboard, though it has a separate number pad

Intel Reveals Core i3, i5, i7 CPU Naming System

Lynnfield, Clarksfield, Arrandale, Clarkdale – all codenames for upcoming Intel chips based on the latest architecture and all very confusing.

ZoomToday we know that the “Core” family for the performance segment goes mainly from Core 2 Duo to Core 2 Quad all the way to the top with Core i7. But with Core 2 on the way out to be replaced by new CPUs later this year, Intel needs to sort out its naming and branding conventions to that consumers will be able to figure out what they’re buying.

Intel corporate communications manager Bill Calder wrote in a blog post, “Today the Intel Core brand has a mind boggling array of derivatives (such as Core2 Duo and Core 2 Quad, etc). Over time those will go away and in its place will be a simplified family of Core processors spanning multiple levels: Intel Core i3 processor, Intel Core i5 processor, and Intel Core i7 processors.”

“Core i3 and Core i5 are new modifiers and join the previously announced Intel Core i7 to round out the family structure. It is important to note that these are not brands but modifiers to the Intel Core brand that signal different features and benefits,” Calder added.

The new Core line will be naturally be position from bottom to top Core i3, Core i5 and Core i7. The odd-numbers convention makes sense with the possibility that some consumers may confused Core 2 Duo and Quad with 2 and 4.

The desktop processors codenamed Lynnfield, which are due this fall, will marketed as both Core i5 or Core i7, depending upon the feature set and capability. Interestingly, all Clarksfield mobile chips will have the Core i7 name.

The lower-cost line will remain mostly unchanged with the Celeron being the entry point, the Pentium for basic computing and the Atom doing what it’s been doing to the netbook and MID segment.

“For PC purchasing, think in terms of good-better-best with Celeron being good, Pentium better, and the Intel Core family representing the best we have to offer,” said Calder. “This will be an evolutionary process taking place over time, and we acknowledge that multiple brands will be in the market next year including older ones, as we make the transition. But overall this is a good thing, designed to make it easier and more rational over the long run.

The WinFast PxVC1100 Video Transcoding Card: Worth The Price?

Sony, Toshiba, and IBM probably didn't put much thought into using the Cell microprocessor as part of a Windows-based PC. Those of you unfamiliar with the Cell Broadband Engine Architecture likely know of its primary role in the consumer space as the CPU platform in the PlayStation 3 game console. You may also have heard about the U.S. Customs Enforcement Cyber Crimes Center using the PS3 running Linux to crack the passwords of suspected child pornographers. Indeed, the Cell processor is a very powerful component, and every Sony PS3 is rated for somewhere around 204 GFLOPS (single-precision float).

Admittedly, a gigaflop, which represents one billion floating point operations per second, is not a perfect metric, as these processors have different strengths and weaknesses. However, the number of gigaflops does give you an idea about the Cell's compute performance. When this article was written, the world's second-fastest supercomputer, the IBM Roadrunner, was using a combination of 12,960 Cell processors and 6,912 Opteron processors.

The trio of Sony, Toshiba, and IBM co-designed the Cell broadband engine architecture. Toshiba has taken the liberty of modifying the Cell processor into something a little more appropriate for multimedia processing by retaining half of the Cell's eight synergistic processor elements (SPEs) and adding video encoding and decoding hardware, it created the SpursEngine processor:

Consuming a mere 10-20W, the SpursEngine is intended to fill the role of a co-processor dedicated to 3D and video processing. With four SPEs running at 1.5 GHz, the SpursEngine is good for about 50 GFLOPS, and capable of 8/16/32-bit integer and single/double precision floating-point calculations. The processor has one megabyte of local memory, 256KB of which are dedicated to each of the four SPEs.

I know what you're thinking: it sounds great, but what can it do for me? Well, Leadtek asked the same question and responded by placing the SpursEngine processor on a video transcoding board called its WinFast PxVC1100.

We look at this SpursEngine-equipped card to show you just what it can do. However, more importantly, we're going to compare its performance to a number of CPUs across the price spectrum to see if your hard-earned dollars are best spent on the WinFast PxVC1100 or if they are better served upgrading your host processor instead.

HP Puts 1000 Cores in a Single Rack

Want to get the most processing power possible in your data center to run cloud computing and Web 2.0 apps? HP is introducing the ProLiant BL2x220c G5 server blade today, which doubles the processing density by putting two servers into each half-height blade. Using Intel Xeon 5400 quad-core processors, you can put up to 1024 cores and 2 terabytes of RAM in 128 servers in a 42U c-Class rack – that’s 12.3 teraflops in eight square feet.

Fitting two servers into a single blade means leaving some things out, Iain Stephen, HP’s vice president for industry standard servers, said.

“The memory, the drives, the processors and the heatsinks are the things that take up the space in a server,” Stephen said. “We stripped off the things customers tell us they don’t value: we stripped off the hot pluggable storage; we stripped off the storage redundancy; we reduced the memory footprint and we have a smaller number of DIMM sockets. When a customer looks at the 220c, they may think it’s underspecified. But on the connectivity side we’ve enhanced things; we can add InfiniBand or high-speed Ethernet. It’s a balance. If I already boot from network-attached storage, if I’m running an app where four DIMMs are sufficient, if I can compromise on local storage and the memory footprint – then I get the processor density."

HP expects customers to use the dual gigabit Ethernet network interface card and optional x8 PCI-Express mezzanine socket allowing 4x double data rate InfiniBand to connect to storage arrays like HP’s petabyte-scale ExDS9100 instead of using storage inside the rack. Making room for more processors creates a much more efficient system, Stephen said. “You have to balance the amount of processing per square foot and the power requirements. You can either drive towards ultimate density or the ultimate in efficiency, but with the 220c you get three times the density of a 1U rack,” Stephen said. “We use the same power supplies, the same fans and the same chassis, but we double up the density and hopefully get 60% better performance per watt.”

Specifically, HP claims a 60% performance-per-watt advantage over a cluster of Dell PowerEdge 1955 servers. In HP’s own tests using the SPECjbb2005 benchmark to measure business operations per second, the BL2x220c delivers 1,582.73 bops/watt compared to 958.86 bops/watt with PowerEdge.

The approach does share similarities with IBM’s iDataPlex system for Web 2.0 computing, Stephen said. “There are only so many things you can flex in the x86 architecture,” Stephen said. “You can flex the I/O, the processing, the number of sockets and cores, the memory – these are the core technologies. We’re flexing the same number of things but the way we deliver the balance is slightly different to the way IBM delivers iDataPlex.”

HP isn’t adding water cooling or other extreme measures to the new blades. Instead, it relies on the c-Class chassis’ features, such as the ability to turn off four or five of its six power supplies to deliver power at 90% efficiency. The c-Class chassis also uses 10 Active Cool Fans, based on the design of jet engines for radio-controlled model aircraft. The fans run at up to 166 miles per hour and are more efficient than the fans in each server. Initially, HP is offering only Intel Xeon 5400 quad-core or Xeon 5200 dual-core processors. HP will have AMD’s quad-core Barcelona processors in other ProLiant servers while Stephen said there could be a dual-server Barcelona blade if there’s demand. “Intel has had a performance advantage since May last year so the majority demand is for Intel processors,” Stephen said. “If Barcelona delivers - and I think it probably will - I expect customer demand to split between the two again.”

Although most customers for the BL2x220c blades will be businesses running cloud computing and Web 2.0 applications or high-performance computing systems where fitting in thousands of servers at a time is critical, with prices starting at $6,349 Stephen predicted the blades will appeal to some smaller companies. “There will be small business customers who look at this and say ‘we’re already using a small storage network, and these are ideal to use as file and print servers, Web servers and application servers,’” Stephen said. But one of the first systems will go to special effects company WETA Digital for use on films like James Cameron’s “Avatar,” “Neon Genesis Evangelion” and the “Halo” adaptation.

The PowerEgde R210 follows the 11th Generation portfolio behavioral specifications and features the same system design commonality and reliability true to the entire portfolio. All 11th Generation servers are built to make the user experience easier.

We put all external ports, power supplies and LED lights in the same location for familiar user experience, as well as, easy installation and deployment.

Robust, metal hard drive carriers and organized cabling are designed to improve component access and airflow across the server.

The PowerEdge R210’s purposeful design also provides quiet acoustics and a LED light display positioned on the front of the server for ease of monitoring.

Energy Optimized Technology

Energy Smart design is a key part of the PowerEdge R210’s purposeful design. Utilizing a low 250 watt power supply, the PowerEdge R210 provides the smallest power footprint within the 11th Generation PowerEdge server portfolio.

Also included in the PowerEdge R210 are low flow fans, which only spin when needed, helping to reduce noise. In addition, the logical component layout of the internal components aids with air flow direction, helping to keep the server cool and quiet.

Simplified Systems Management

The Lifecycle Controller is the engine for advanced embedded management and is delivered as part of the optional iDRAC Express or iDRAC Enterprise in the PowerEdge R210.

The Lifecycle Controller is a chip that is integrated on the server. It helps to simplify administrator tasks by performing a complete set of provisioning functions such as system deployment, system updates, hardware configuration and diagnostics from a single intuitive interface called Unified Server Configurator(USC) in a pre-OS environment. This eliminates the need to use and maintain multiple pieces of disparate CD/DVD media.

Also part of Dell’s Open Manage™ portfolio is the Dell Management Console which is included with every Dell server and provides IT administrators with a consolidated console view of their IT infrastructure.

PowerEdge 2970 Rack Server

Balance of Features and Size The highly versatile AMD-based Dell PowerEdge 2970 2-socket 2U rack server provides the optimal balance of server features and size. It gives businesses the ability to maximize server performance while keeping space and energy needs to a minimum. Designed to support almost any type of enterprise application — including database, email and network infrastructure — it has the versatility that businesses require.

Use Energy Optimally

Power infrastructure and consumption already account for nearly half the cost of a typical data center and could soon cost half of the typical overall IT budget. That said, Dell offers the PowerEdge Energy Smart 2970 for customers seeking a highly energy-efficient server — Dell is the only major server vendor to offer a complete lineup of these energy-optimized servers.

Due to its smart design, the PowerEdge Energy Smart 2970 version provides up to 27 percent greater performance per watt when compared to the HP DL385 G2 and up to 18 percent when compared to the IBM x3655².

Protect Your Information

6) Don't install suspicious software.
7) Protecting your computer system with passwords.

computer internet

In this modern era most of the people have heard about Internet or known about it. Only some of the people have never heard of internet, however most of them have either used the internet occasionally or frequently. To know that the internet has attracted an enormous amount of attention past few years it does not take time to knowabout internet.

what would be the cause of thousands of companies millions of people and virtually every majors countries investing millions of dollars into internet?what truly is all this fuss about?
They say that its because of the speed of wide variety of information's found on the net and it is easy to access and publish information's on the internet.

BENEFITS: The internet speed vast resources and its ability to directly communicate with others around the world. Internet uses the quickness of computers to transmit its data, information can travel at tremendous speed. The inter sues hundreds of thousands of computers all connected to each other to store vast amount of information. And because the internet allows for individuals to have specific electronic mail address, people can easily communicate with one another from any corner of the world.
Internet is considered by many to be superior to the best and biggest libraries in the country. Internet ability to deliver this vast amount of information has drawn even more users. Instead of reading a medical breakthrough in next month's journal, it can be published on the internet instantly. Breaking news events can be published almost immediately after the event occurs. People don't have to wait until the morning paper to read about an event. Part of this internet has helped to make the internet a technological breakthrough.
How did the internet begin?
The history of Internet is not complicated not that long. 25years ago the internet began as an experiment of U.S Defense Department. The fact it was not originally designed for the public's personal use. Originally the goal of the internet was establish a system to safeguard the exchange information among different government agencies in the event war. Without a computer or person controlling the internet, the enemy could not destroy means of communication with just one military strike. Today this unique features of the internet remains constant and part of its success. No one person or organization controls or heads the internet. It is basically hosted by thousands of individual computer have registered with NSF(National Science Foundation) for an Internet address.

computer network

INTRODUCTION:
Computer network is interconnection between computers through electronic circuits and wireless transmissions of various designs and technologies for the purpose of exchanging data or communicating information's between them or their users. Networks may be classified according to a wide variety of characteristics.
A computer network allows sharing of resources and information among devices connected to the network. The Advanced Researcher Project Agency (ARPA) funded the design of the advanced Research Department of Defense. It was the first operational computernetwork in the world. Development of network began in 1969, based in the designs developed during the 1960s.

PURPOSE:
1) Facilitating communications. Using a network, people can communicate efficiently and easily via e-mail, instant messaging,chat rooms, telephony, videos telephone calls, and videoconferencing.
2) Sharing hardware. In a networked environment , each computer on a network can access and use hardware on the network. Suppose several personal computers on a network each require the use of laser printer. If the personal computer and a laser printer are connected to a network, each user can then access the laser printer on the network, as they need it.
3) Sharing files, data, and information. In network environment, any authorized user can access data and information stored on others computer on the network. The capability of providing access to data and information on shared storage devices is an important feature of many networks.
4) Sharing software. Users connected to a network can access application programs on the network.

CONNECTION METHOD:
Computer networks can be classified according to the hardware and software technologies that is used to interconnect the individual devices in thenetwork, such as optical fiber, Ethernet, Wireless LAN, Home PNA, Power line communication.
Ethernet uses physical wiring to connect devices. Frequently deployed devices include hubs, switches, bridges and routers. Wireless LAN technology is designed to connect devices without wiring. These devices use radio waves or infrared signals as transmission medium. ITU-TG technology uses existing home wiring(coaxial cable, phone line and power lines) to create a high-speed (up to 1 Gigabyte/s ) local area network.

NETWORK CLASSIFICATION
1) WIRED TECHNOLOGIES
2) WIRELESS TECHNOLOGIES

1) WIRED TECHNOLOGIES:
* Twisted-pair wire the most widely used medium for telecommunication. Twisted-pair wire ordinary telephone wires which consist of two insulated copper wires twisted into pairs and are used for both voice and data transmission.
* Coaxial cable is widely used for cable television systems, office buildings, and other work sites for local area networks. The cable consists of copper or aluminum wire wrapped with insulating layer typically of a flexible material with a high dielectric constant, all of which surrounds by a conductivity layer.
* Fiber optical cable consists of one or more filaments of glass fiber wrapped in protective layer. It transmits light which can travel over extended distances without fiber optical cables. Transmission speed may reach trillions of bits per second. The transmission speed of fiber optical is hundred of times faster than coaxial cables and thousand of times faster than twisted pair wire.

2) WIRELESS TECHNOLOGIES:
* Terrestrial microwaves use Earth based transmitter and receiver. The equipment look similar to satellite dishes. Terrestrial microwave uses low gigahertz range which limits all communications to line of sight. Path between relay stations spaced approx 30miles apart.
* Communications Satellites uses microwave radio as their telecommunications medium which are not deflected by Earth's atmosphere. The satellites are stationed in space, typically 22,00 miles above equator.
* The wireless Web refers to the use of World Wide Web through equipments like cellular phones, pagers, PDAs, and other portable communication devices.

Computer OSI several layers model

The year 1980s the Europeans-dominated International Standards Organization(ISO) networking suite. OSI has two majors components an abstract model of networking and a set of concrete protocols.
Parts of OSI has influenced Internet protocols development, but none more than the abstract model itself, documented in OSI 7498 and its various addenda. In the model, anetworking system is divided into layers. Inside each layer, one or more entities implement its functionality. Each entity interacts directly only with the layer immediately beneath it, and provides facilities for us by the layer above it. Protocols enable and entity in one host to interact with a corresponding entity at the same layer in a remote host.

The seven layers of OSI Basic reference Model:
1) The Physical Layer describes the physical properties of the various communications media, as well as the electrical properties and interpretation of the exchanged signals. It defines the size of the Ethernet coaxial cable, the type of BCN connector used, and the termination method.
2) Data Link Layer describes the logical organization of data bits transmitted on a particular medium. It defines the framing, addressing and check summing of Ethernet packets.
3) Network layer describes how a series of exchanges over various data links can deliver data between any two nodes in network. It defines the addressing and routing structure of internet.
4) Transport Layer describes the quality and nature of the data delivery. It defines if and how retransmissions will be used to ensure data delivery.
5) Session Layer describes the organization of data sequences layer than the packets handled by lower layers. It describes how request and reply packets are paired in remote procedure call.
6) Presentation Layer describes the syntax of data being transferred. It describes how floating point numbers can be exchanged between hosts with different math formats.
7) Application Layer describes how real work actually gets done. It implements file system operations.

The original Internet protocol specification defined a four-level model,and protocols designed around it(like TCP) have difficult fitting neatly into the seven-layers model. Most newly designed use the seven-layer.

OSI Basis Reference Model has enjoyed a far greater acceptance than the OSI protocols themselves. There are several reasons for this. OSI's committee-based design process bred overgrown, unimaginative protocols that nobody ever accused of efficiency.
