Today, the term information technology has ballooned to encompass many aspects of computing and technology, and the term has become very recognizable. The information technology umbrella can be quite large, covering many fields. IT professionals perform a variety of duties that range from installing applications to designing complex computer networks and information databases. A few of the duties that IT professionals perform may include data management, networking, engineering computer hardware, database and software design, as well as the management and administration of entire systems.Conference By Computer
The Fifteenth Conference on Computers, Freedom, and Privacy was held in Seattle. The theme of this conference was equiveillance, the balance between surveillance and sousveillance. The equiveillance theme was reflected in the Opening Keynote Address, a panel discussion on equiveillance, and a pre-keynote sousveillance workshop, as well as a sousveillance performance [1]. In keeping with this theme, every conference attendee received a sousveillance system consisting of a "maybecamera" attached to each conference bag. Some of the 500 conference bags contained cameras transmitting live 24/7 video whereas others contained no camera, but merely the familiar camera dome. A third category of conference bag included some with a subtle but visible flashing red light behind the dome
Use Computer To Get Fit
Today's teens often feel overwhelmed by their many commitments. School assignments social engagements, family responsibilities and the demands of part-time jobs are typical for most teens, with many more adding an extracurricular activity such as music or sports to the blend. When you add up all that they have on their plates, teens are often some of the busiest people in their families. Finding ways to manage their daily commitments without letting the pressures become troublesome can require some creative scheduling and prioritising, but it can be done.Computer Games
computer game or simply PC game) is a game played on a personal computer, rather than on a video game console or arcade machine. Computer games have evolved from the simple graphics and gameplay of early titles like Spacewar!, to a wide range of more visually advanced titles.[1] PC games are created by one or more game developers, often in conjunction with other specialists (such as game artists) and either published independently or through a third party publisher. They may then be distributed on physical media such as DVDs and CDs, as Internet-downloadable shareware, or through online delivery services such as Direct2Drive and Steam. PC games often require specialized hardware in the user's computer in order to play, such as a specific generation of graphics processing unit or an Internet connection for online play, although these system requirements vary from game to game.
Touchscreen Computer
A touchscreen is a display which can detect the presence and location of a touch within the display area. The term generally refers to touch or contact to the display of the device by a finger or hand. Touchscreens can also sense other passive objects, such as a stylus. However, if the object sensed is active, as with a light pen, the term touchscreen is generally not applicable. The ability to interact directly with a display typically indicates the presence of a touchscreen.
The touchscreen has two main attributes. First, it enables one to interact with what is displayed directly on the screen, where it is displayed, rather than indirectly with a mouse or touchpad. Secondly, it lets one do so without requiring any intermediate device, again, such as a stylus that needs to be held in the hand. Such displays can be attached to computers or, as terminals, to networks.
Computer Software
Computer software, or just software is a general term used to describe a collection of computer programs, procedures and documentation that perform some tasks on a computer system.[1]
The term includes:
- Application software such as word processors which perform productive tasks for users.
- Firmware which is software programmed resident to electrically programmable memory devices on board mainboards or other types of integrated hardware carriers.
- Middleware which controls and co-ordinates distributed systems.
- System software such as operating systems, which interface with hardware to provide the necessary services for application software.
- Software testing is a domain independent of development and programming. It consists of various methods to test and declare a software product fit before it can be launched for use by either an individual or a group.
Computer Hardware
Your PC (Personal Computer) is a system, consisting of many components. Some of those components, like Windows XP, and all your other programs, are software. The stuff you can actually see and touch, and would likely break if you threw it out a fifth-story window, is hardware.
Not everybody has exactly the same hardware. But those of you who have a desktop system, like the example shown in Figure 1, probably have most of the components shown in that same figure. Those of you with notebook computers probably have most of the same components. Only in your case the components are all integrated into a single book-sized portable unit.
The system unit is the actual computer; everything else is called a peripheral device. Your computer's system unit probably has at least one floppy disk drive, and one CD or DVD drive, into which you can insert floppy disks and CDs. There's another disk drive, called the hard disk inside the system unit, as shown in Figure 2. You can't remove that disk, or even see it. But it's there. And everything that's currently "in your computer" is actually stored on that hard disk. (We know this because there is no place else inside the computer where you can store information!).

Computer Animation
Computer animation (or CGI animation) is the art of creating moving images with the use of computers. It is a subfield of computer graphics and animation. Increasingly it is created by means of 3D computer graphics, though 2D computer graphics are still widely used for stylistic, low bandwidth, and faster real-time rendering needs. Sometimes the target of the animation is the computer itself, but sometimes the target is another medium, such as film. It is also referred to as CGI (computer-generated imagery or computer-generated imaging), especially when used in films.Internet
The Internet is a global network of interconnected computers, enabling users to share information along multiple channels. Typically, a computer that connects to the Internet can access information from a vast array of available servers and other computers by moving information from them to the computer's local memory. The same connection allows that computer to send information to servers on the network; that information is in turn accessed and potentially modified by a variety of other interconnected computers. A majority of widely accessible information on the Internet consists of inter-linked hypertext documents and other resources of the World Wide Web (WWW). Computer users typically manage sent and received information with web browsers; other software for users' interface with computer networks includes specialized programs for electronic mail, online chat, file transfer and file sharing.Computer Graphics
Graphics
Graphics are visual presentations on some surface, such as a wall, canvas, computer screen, paper, or stone to brand, inform, illustrate, or entertain. Examples are photographs, drawings, line art, graphs, diagrams, typography, numbers, symbols, geometric designs, maps, engineering drawings, or other images. Graphics often combine text, illustration, and color. Graphic design may consist of the deliberate selection, creation, or arrangement of typography alone, as in a brochure, flier, poster, web site, or book without any other element. Clarity or effective communication may be the objective, association with other cultural elements may be sought, or merely, the creation of a distinctive style.
My Faster computer
As you know or not, Windows XP and Vista has a delay when you mouse over a menu. By default, Windows takes 400 miliseconds to show the menu items after you mouse over the menu. Sometimes, we think it’s too slow and of course we have a not so fast computer, make it so slowpoke’s performance. Actually, we can shorten the delay, even make it to zero. But, I recommend not to set it to zero, because it’s “too fast!”.When your computer starts to show some trouble by slowing down or degradation of service and loud noise, you can pinpoint the source of the problem by using a computer diagnostic utility. When you buy a new computer, it comes with a diagnostic utility. You can start diagnosing by inserting the diagnostic tool CD into the CD/DVD bay. You can run it at boot up or navigate inside the CD and then run the diagnostic tool by clicking on it.
World’s Fastest Computer
The official TOP 500 Supercomputers list, released Nov. 12, reports the machine is now three times faster than its competitors with 478 trillion calculations per second, or 478 “teraflops.” The Blue Gene/L is housed at Lawrence Livermore National Laboratory in California. IBM has a record 232 supercomputers on the TOP 500 list, the vast majority built with commodity style, PC microprocessors. The computer maker also outlined its plans to next year achieve a computing milestone known as a “petaflop” – the ability to process 1,000 trillion calculations per second.Laptop Security
Security
Being expensive, common and portable, laptops are prized targets for theft. The cost of the stolen business or personal data and of the resulting problems (identity theft, credit card fraud, breach of privacy laws) can be many times the value of the stolen laptop itself. Therefore, both physical protection of laptops and the safeguarding of data contained on them are of the highest importance.
Most laptops have a Kensington security slot which is used to tether the computer to a desk or other immovable object with a security cable and lock. In addition to this, modern operating systems and third-party software offer disk encryption functionality that renders the data on the laptop's hard drive unreadable without a key or a passphrase.
Laptop Computer
A mini laptop is a computer about half the size of a regular laptop. It has smaller screen, hard drive, memory, and usually slower CPU. Mini laptops and the MS Windows Mobile platform are not the same thing and should not be confused. Here, we discuss mini laptops that use the standard Windows platform (or, in some cases, the Linux platform). Although standard laptops are quite portable, your lifestyle or work style may demand something even more mobile. Mini laptops weigh about 1.5 lb, and they fit in most handbags, or even large pockets. They are able to meet most of your computing needs without too much loss in performance - or at least that is their aim.Super Computer
- A supercomputer generates large amounts of heat and must be cooled. Cooling most supercomputers is a major HVAC problem.
- Information cannot move faster than the speed of light between two parts of a supercomputer. For this reason, a supercomputer that is many metres across must have latencies between its components measured at least in the tens of nanoseconds. Seymour Cray's supercomputer designs attempted to keep cable runs as short as possible for this reason: hence the cylindrical shape of his Cray range of computers. In modern supercomputers built of many conventional CPUs running in parallel, latencies of 1-5 microseconds to send a message between CPUs are typical.
Thin Client Computer
A remarkable advancement in Computing arena
Thin-Client solutions remove the hassle of managing, updating and supporting the PCs in your organisation. The user would typically not know the difference between working on a PC and a thin-client. The thinclient resembles a small PC, but has no mechanical components, such as fans and hard disks; no moving parts which means massively reduced hardware failure rates.

New Desktop Computer
Realizing that people like computers to be good looking as well as functional, Dell has made massive strides over the last year or two in revamping their products' austere image. The new Studio Hybrid desktop is no exception to this rule. The new machine is being marketed as appropriate not just in the office, but anywhere in the home, including in a spot in your home theater setup. With an optional Blu-Ray disc drive, up to 4GB of RAM and a Core 2 Duo processor, Dell's proving that big things can come in small packages.Design
Dell hails the new Hybrid Studio as being 80% smaller than a traditional desktop computer, while using around 70% of the power -- this is largely due to the use of several laptop components in the build. They have managed to get an Energy Star 4.0 certification but that isn't where their environmentally-friendly efforts stop. Packaging and paper documentation have been greatly reduced and is almost 95% recyclable. A system recycling kit is also included.
Home Computer
Many home computers were superficially similar. Most had a keyboard integrated into the case; sometimes a cheap-to-manufacture chiclet keyboard in the early days, although full-travel keyboards quickly became universal due to overwhelming consumer preference. Most systems could use an RF modulator to display 20–40 column text output on a home television. The use of a television set as a display almost defines the pre-PC home computer. Although dedicated computer monitors were available for this market segment, it was often a later purchase only made after users had bought a floppy disk drive, printer, modem, and the other pieces of a full system. This "peripherals sold separately" approach is another defining characteristic of home computers.Teblet Pc
A Tablet PC is a laptop or slate-shaped mobile computer, equipped with a touchscreen or graphics tablet/screen hybrid to operate the computer with a stylus or digital pen, or a fingertip, instead of a keyboard or mouse. This form factor offers a more mobile way to interact with a computer. Tablet PCs are often used where normal notebooks are impractical or unwieldy, or do not provide the needed functionality.There are many operating systems in use on devices marketed as tablets. Note that most tablet PC software is targeted particularly for the Microsoft Tablet PC API, and will not run on devices without Windows Vista or Windows XP Tablet PC Edition. Care should be taken when researching a tablet system or any device or software that claims to be designed for tablet PCs, as the phrase does not guarantee compatibility.
Ideal Computer
A PC may be a home computer, or may be found in an office, often connected to a local area network (LAN). This is in contrast to the batch processing or time-sharing models which allowed large expensive systems to be used by many people, usually at the same time, or large data processing systems which required a full-time staff to operate efficiently. While early PC owners usually had to write their own programs to do anything useful with the machines, today's users have access to a wide range of commercial and non-commercial software which is provided in ready-to-run form.
Personal Computer
A personal computer (PC) is any general-purpose computer whose size, capabilities, and original sales price make it useful for individuals, and which is intended to be operated directly by an end user, with no intervening computer operator. As of 2009, a PC may be a desktop computer, a laptop computer or a tablet computer. The most common operating systems for personal computers are Microsoft Windows, Mac OS and Linux, while the most common microprocessors are x86-compatible CPUs, ARM architecture CPUs and PowerPC CPUs. Software applications for personal computers include word processing, spreadsheets, databases, Web browsers and E-mail clients, games, and myriad personal productivity and special-purpose software. Modern personal computers often have high-speed or dial-up connections to the Internet, allowing access to the World Wide Web and a wide range of other resources.
Shuttle D10 Desktop Computer
This isn’t the first time, and no doubt the last time we’ll see a desktop computer with a built-in LCD. Sure, the built-in monitor’s application is pretty limited, but it might give you that warm and fuzzy 80s feeling from the days of huge ass portable TVs, remember those? I think you got a 4 inch B&W screen in a tower sized box. The Shuttle D10’s screen achieves a 800×480 resolution and you can choose between a Core 2 Duo E4000 series, E2000 series, or Celeron 400 series processor. Other features are 2GB of RAM, 4 USB ports and probably a DVD burner ala tray format. The price is rumored to be around $500 and no word on whether it will come stateside.
Computer Components
- Central Processing Unit (CPU) is also an IC. The term CPU is often used to describe the case and internal components, however it more correctly refers to the main processor that executes program instructions and performs mathematical calculations.
- Printed Circuit Board (PCB): PCBs are the principal material that contains the computer's basic circuitry and components. The largest PCB is the motherboard, which connects the components of the computer (e.g. CPU, input and output devices, RAM and storage devices) to one another. Expansion slots on the motherboard allow for the insertion of daughter boards that provide further input and output connections (e.g. sound, modem, networking, video). Circuitry is imprinted or affixed to the surface of the board; this involves the use of metals (primarily copper, with gold-plated connectors) to provide the circuit, embedded in a fibreglass board using either glue or solder. Fire retardants are usually incorporated into the manufacture of PCBs.
- Storage: Information can be stored on fixed devices (e.g. magnetic "hard" drive) or removable devices that use any one of a range of consumable media (e.g. 3.5" magnetic disks, CD-ROM, digital tape, flash memory cards and Zip disks).
- Power Supply: The power supply takes mains power and transforms it to the voltages required by the CPU, motherboard and input/output devices. Metal and some plastic components are used in their construction.
Notebook or Desktop Computer
Portable computers cost more, so unless you really have the need for one, you get a lot more computer for your money with a regular desktop PC. The main thing is portability. If you need a portable computer, get a laptop. ("Laptop," "portable," and "notebook" all refer to the same thing, by the way). Otherwise, a desktop computer is a better buy, and better ergonomically.- The Price Difference
You might wonder why laptops cost more than desktop computers with comparable features and power. That is largely because it is more expensive to manufacture laptops and their parts. For portable computer components, factors such as compactness, the amount of heat they generate, their weight, and power consumption are more important than they are for desktops. Those factors add to their manufacturing costs.
Cellular Computer
It's not your normal, electronic silicon-based machine, but scientists have made a computer from a small, circular piece of DNA, then inserted it into a living bacterial cell and unleashed the microbe to solve a mathematical sorting problem."A computer is any system that can read some input and give some readable output," says Karmella Haynes, a biologist at Davidson College in North Carolina and co-author of a new study appearing in the Journal of Biological Engineering. Haynes and her team looked to harness the power of DNA recombination to solve the so-called "burnt pancake problem": a puzzle about how to stack different-size flapjacks that are burned on one side and perfectly cooked on the other using the fewest number of flips to arrange them so the largest are on the bottom and all are golden side up.
Computer Repair
The proliferation of computer technology in businesses and the workplace has created a huge demand for people that can set up, fix, and maintain computers and related technology. This is the job of the computer technician.
A computer technician should be familiar with the various operating systems (MS Windows, Macintosh, Linux) and the computer applications they will encounter as well as how to work with computer hardware and set up computer peripherals (printers, scanners, etc.). Courses specifically geared to computer technicians will cover a broad range of technologies.
CompTIA’s A+ is one of the most common certifications and is geared specifically towards computer technicians. Many people that earn their A+ go on to earn more advanced certifications like the MCSE, CCNA, or CNE.
Mini Computer
Distributed computer systems have been the subject of a vast amount of research. Many prototype distributed computer systems have been built at university, industrial, commercial, and government research laboratories, and production systems of all sizes and types have proliferated. It is impossible to survey all distributed computing system research. Instead, this paper identifies six fundamental distributed computer system research issues, points out open research problems in these areas, and describes how these six issues and solutions to problems associated with them transect the communications subnet, the distributed operating system, and the distributed database areas. It is intended that this perspective on distributed computer system research serve as a form of survey, but more importantly to illustrate and encourage a better integration and exchange of ideas from various subareas of distributed computer system research.
Protect your computer
Cyber criminals, like most criminals, are opportunistic. They seek out vulnerabilities on computers to send spamG and phishingG emails or try to trick people into providing information that allow criminals to pillage bank accounts and steal identities.
Home computers are favorite targets of criminals. You need to be vigilant by employing the latest in security technology and by employing the same intuition you use in the “offline” world:
- Use a variety of tactics and technologies to make it as difficult as possible for criminals to access your home computer; and
- Hone your instincts about when and where it’s appropriate to share personal information
Car Computer
How small can a computer get? This time less than the size of three stacked DVD cases... Not the worlds smallest car PC, but this time there are no compromises on processing power; state of art Intel Celeron and Core Duo processors enable any application to run smoothly. The build-in GPS receiver and the build-in FM/RDS/TMC receiver provide navigation tools with high-speed location updates and with real-time traffic information. And there is no need for an additional power supply or power controller as all that is integrated on the specially designed mainboard.Computer Rocks
A computer is a machine that manipulates data according to a list of instructions.
The first devices that resemble modern computers date to the mid-20th century (1940–1945), although the computer concept and various machines similar to computers existed earlier. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers (PC).[1] Modern computers are based on tiny integrated circuits and are millions to billions of times more capable while occupying a fraction of the space.[2] Today, simple computers may be made small enough to fit into a wristwatch and be powered from a watch battery. Personal computers, in various forms, are iconsof the Information Age and are what most people think of as "a computer"; however, the most common form of computer in use today is the embedded computer. Embedded computers are small devices that are used to control other devices—for example, they may be found in machines ranging from fighter aircraft toindustrial robots, digital cameras, and children's toys.
The ability to store and execute lists of instructions called programs makes computers extremely versatile and distinguishes them fromcalculators. The Church–Turing thesis is a mathematical statement of this versatility: any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks given enough time and storage capacity.
