| 1. | Personal computer (PC) is a machine which quickly performs calculations and instructions. Designed to be based by a single person, a PC is smaller, less expensive and easier to use then supercomputers, mainframe computers. |
| 2. | PC have revolutionized science, art, mass media, medicine, education, business. Musicians use them for learning, creating and recording music. Businesses track finance and forecast company performances using PCs. Foreign correspondents can compose new stories on portable PCs, called laptops and electronically submit these stories from remote locations. |
| Many people work at home and communicate with workers via their PCs in a practice known as telecommunicating. PCs are also able to interface with worldwide communication networks such as Internet and www (world wide web) to find information on any subject. | |
| 3. | PCs consist of a microprocessor which directs logical and arithmetical functions and runs computer programs. It also has electronic memory to temporarily store programs and data, and mass storage devices such as hard, floppy and compact discs (CD-ROM) devices to permanently store programs and data. Information and commands are entered by the user via a keyboard or by a mouse. Information from the PC is displayed on a video monitor on a liquid crystal display (LCD) video screen, or it can be printed on laser or inkjet printers. |
| 4. | In 1940s, early computers were the size of houses and were very expensive. The invention of integrated circuits and microprocessors enables computer makers to combine the essential elements of a computer onto silicon computer chips. The first microprocessor the Intel 4004, created by Intel Corporation was designed to be the computing and logical processor of calculators and watches. From its simple design modern microprocessor involved. |
| 5. | The Altair 8800 is considered to be the 1st PC. It appeared on the cover of Popular Electronics Magazine in 1975 and inspired many computer enthusiasts to produce hardware and software. |
| 6. | American computer designers Steven Jobs and Stephen Wozniak, working in their garage, created Apple II in 1977, one of the 1st PCs to incorporate a colour video display and a keyboard that made a computer easy to use. In 1981 International Business Machine (IBM) Corporation introduced the IBM PC, which became the PC standard. The Apple Macintosh, developed in 1984, featured a graphical user interface (GUI) a visual appealing way to represent computer commands and data on the screen. The Macintosh combines icons (pictures that represent files and programs) with windows (boxes that each contain an open file or program). Information on the screen was controlled by a device known as a mouse. During the last 20 years, computing power has doubled about every 18 months thanks to the creation of faster microprocessors, development of new storage technologies. These technological advances will make PCs more powerful and useful. |
