Graphics card
A GeForce 4 4200-based graphics card
A graphics card or video card is a component of a computer which is designed to convert a logical representation of an image stored in memory to a signal that can be used as input for a display medium, most often a monitor utilising a variety of display standards. Typically, it also provides functionality to manipulate the logical image in memory.

Overview
As was in the past, many graphics cards are separate devices, attached to a PC motherboard via the ISA, PCI, VESA, or AGP buses, with recently-introduced PCI-Express expected to be prominent in the future.
Increasingly, however, the graphics card is no longer a "card" in the strictest sense, but is an integrated section of the motherboard dedicated to the same purpose. Integrated-graphics-displays usually have inferior 3D performance compared with dedicated graphics cards (due to using cheaper chipsets and sharing system memory rather than using dedicated memory); those who require high performance still prefer non-integrated solutions. Integrated graphics displays have gradually become more common since the mid 1990s as advancing technology makes them more practical. Anyone using their computer for office tasks, web browsing, email and such things will be fine with an integrated graphics chip.
The most powerful graphics hardware, usually geared towards 3D graphics for games, is still card-based. Their processing engines are sometimes called GPUs (graphics processing units). The longterm goal of graphics cards manufacturers (and game developers) appears to be realtime photorealistic rendering. New products and technologies are often touted to provide "Hollywood quality" - 3dfx used claims of movie-quality effects to promote their Voodoo 5 cards with T-Buffer technology, allowing motion blur, depth of field and full screen anti-aliasing effects. nVidia talked about "The dawn of cinematic computing" when introducing its GeForce FX chip with the Dawn technology demo. Others use the new technology for more impressive, but unrealistic rendering, such as cel shading.
Conversely, sometimes 3D-graphics capabilities are not relevant to the choice of high-performance graphics card; 2D graphics and fine visual-quality fill specialised niches in areas such as medical imaging. The original hardware accelerated 3D Tenderers come on a board that was used in conjunction with a normal graphics card. The card would add 3D graphics to the 2D rendering from the graphics card via a pass-through cable. The first consumer-level 3D hardware was the Voodoo by the now defunct 3dfx.

Bill Gates, the Software King
1. Most of the computers in the world use software invented by Bill Gates, the founder of Microsoft Inc. of Redmond, Wash. Software is the set of programs that make computers whether business or personal perform various tasks.
2. Gates was born in Seattle, Washington, in 1955. As a boy, he was bright and curious. He was active in Scouting, reaching Life Scout rank in Troop 186. He especially loved hiking, camping and other outdoor adventures.
3. But Gates was obsessed with computers. While a student at Harvard University in 1975, Gates and a friend Paul Allen, developed a computer language for an early version of the personal computer. Microsoft was born. Gates went on to develop operating systems, such as MS-DOS and software programs.
4. Thanks to Microsoft. Gates is now one of the richest men in America. He is worth more than $8 billion
5. A technical wizard and a fierce business competitor. Gates sees great things ahead for computers. He says they "are really going to change a lot of things in the world the way we work, the way we play and entertain ourselves and even the way we are educated.
THE BINARY NUMBER SYSTEM
6. Early digital computers inspired by Howard Aiken's Mark I were huge, sometimes filling an entire room. That was because thousands of switches were needed to compute his binary number system.
7. In the binary number system, only two digits are recognized by the Computer: 0 when a switch is off, and 1 when the switch is on. Different combinations of those two digits can represent thousands of letters and numbers.
8. The binary number system is still used in today's computers. The difference is that the thousands of electrical switches have been replaced by one tiny solid-state chip than does the translations electronically. That's why your computer only fills up part of your desk, not your whole bedroom.
COMPUTERS IN YOUR FUTURE
9. Microsoft's Bill Gates and other computer experts see great things ahead. In the next few years, you will be able to sit at your computer and see high-quality video sent from any place on earth.
10. They predict you will also have a wallet-size personal computer. With it you will be able to store photographs, pay bills, get the news, send messages, see movies and open locks with digital keys.
11. At home on your TV size PC you will be able to see and talk with friends in other states, get medical advice, check magazine articles and pictures in a far-off library and order a pizza.
12. A computerized control system at home will regulate your lighting, temperature and security system.
13. Big dreams?
14. Perhaps. But engineers are working to make it reality.

Computer Science
Computer science is a part of an applied mathematics. Specialists in computer science say that this field of knowledge is very interesting because it deals with computer-aided-design (CAD) and computer-aided-manufacturing (CAM).
Computers are intended to improve the productivity of labour of scientists, designers, engineers, managers, and other specialists, because computers offer quick and optimal solutions. One of the main goals of using CAD/CAM is to shorten tjje time between designing and manufacturing.
Moreover, computers came in our life and to our houses and now we can solve our everyday problems with their help.
Computers can be divided into simple and complex devices. Simple computers such as calculators can perform addition, subtraction, multiplication and division. As far as complex computers are concerned they can do different logical operations and some of them even have artificial intelligence.
Thus in order to elaborate up-to-date and inexpensive programs as well as to defend them from viruses, it is important to know some programming languages.
There are low-level programming languages such as a machine language and an assembly language and high-level programming languages, for instance, FORTRAN, PASCAL, ADA, C, BASIC, etc.

Internetworking challengers
The Internet is the world's largest computer network. It is a global information infrastructure comprised of millions of computers organized into hundreds of thousands of smaller, local networks. The term "information superhighway" is sometimes used to describe the function that the Internet provides: an international, high-speed telecommunications network that offers open access to the general public.
The Internet provides a variety of services, including electronic mail (e-mail), the World Wide Web (WWW), Intranets, File Transfer Protocol (FTP), Telnet (for remote login to host computers), and various file-location services.
Electronic mail, or e-mail, is the most widely used function used on the Internet today. Millions of messages are passed via Internet lines every day through-out the world. Compared to postal service, overnight delivery companies, and telephone conversations, e-mail via the Internet is extremely cost-effective and fast. E-mail facilities include sending and receiving messages, the ability to broadcast messages to several recipients at once, storing and organizing messages, forwarding messages to other interested parties, maintaining address books of e-mail partners, and even transmitting files (called "attachments") along with messages.
Internet e-mail messages are sent to an e-mail address. The structure of an e-mail address is as follows: PersonalID@DomainName
The personal identifier could be a person's name or some other way to uniquely identify an individual. The domain is an indicator of the location of that individual, and appears to the right of the "at" (@) sign. A domain name is the unique name of a collection of computers that are connected to the Internet, usually owned by or operated on the behalf of a single organization (company, school, or agency) that owns the domain name. The domain name consists of two or more sections, each separated by a period.
From right-to-left, the portions of the domain name are more general to more specific in terms of location. In the United States, the rightmost portion of a domain is typically one of the following:
comindicating a commercial enterprise
eduindicating an educational institution
govindicating a governmental body
milindicating a military installation
netindicating a network resource
orgindicating a nonprofit organization
In November of 2000 seven new domain names were created and made available: biz,.info,.name,.pro,.aero,.coop, and.museum.
In non-U.S. countries, the rightmost portion of a domain name is an indicator of the geographic origin of the domain. For example, Canadian e-mail addresses end with the abbreviation "ca."
SPAM.
Commercial abuse of e-mail continues to be problematic as companies attempt to e-mail millions of online users in bulk. This technique is called "spam," so named after a skit by the comedy troupe Monty Python that involved the continuous repetition of the word. Online users are deluged with a massive amount of unwanted e-mail selling a wide array of products and services. Spam has become a network-wide problem as it impacts information transfer time and overall network load. Several organizations and governments are attempting to solve the spam problem through legislation or regulation.
VIRUSES.
Computer viruses spread by e-mail have also grown as the Internet has grown. The widespread use of e-mail and the growing numbers of new, uninformed computer users has made it very easy to spread malicious viruses across the network. Security issues for both personal computers and for network servers will continue to be a crucial aspect of the ongoing development of the Internet and World Wide Web.
WORLD WIDE WEB
The World Wide Web (WWW) is a system and a set of standards for providing a graphic user interface (GUI) to Internet communications. The WWW is the single most important factor in the popularity of the Internet, because it makes the technology easy to use and gives attractive and entertaining presentation to users.
Graphics, text, audio, animation, and video can be combined on Web pages to create dynamic and highly interactive access to information. In addition, Web pages can be connected to each other via hyperlinks. These hyperlinks are visible to the user as high-lighted text, underlined text, or images that the user can click to access another Web page.
BROWSERS.
Web pages are available to users via Web browsers, such as Mozilla/Firefox, Netscape Navigator, or Microsoft's Internet Explorer. Browsers are programs that run on the user's computer and provide the interface that displays the graphics, text, and hyper-links to the user. Browsers recognize and interpret the programming language called Hypertext Markup Language (HTML). HTML includes the ability to format and display text; size and position graphics images for display; invoke and present animation or video clips; and run small programs, called applets, for more complex interactive operations. Browsers also implement the hyperlinks and allow users to connect to any Web page they want.
