History of the Computer :: essays research papers

In this report, youll approximately the components and history regarding the computer. A computer is a devise that processes, organize, and calculate, displays information. It chiffonier turn over with other computers all over the world. The most powerful computer arsehole perform 10s of billion of calculations per second. People use computers for business, track inventories, and use blackball codes, personal home use and other things. Computers can produce information, numbers, images, sounds and movies. engraft computers control machinations such as remote controls.Lets talk about the requisite parts of the computer. First you have a bun in the oven your outside units like your printer, monitors, modem, floppy dish antenna drive, CD ROM drive, scanner, speakers and keyboard. These things be called peripherals. Printers come in inkjet, laser and thermal. Lasers are much faster than inkjets. The monitor is the television like unit whither you follow text and images. Mode ms permit us to connect to the Internet, which is a global talk network. Modems come in many different speeds. Some are 14.4k, 56k these uses a phone line, cable modem (in only large cities, an internet setup that uses a cable line) and many more. Floppy disk drives are drives where you insert a disk to save progress or install programs from .CD ROMs are urge on disk that can read only memory. Scanners are flatbed devises that you can look at pictures at more closely. Speakers allow us to here the sounds coming from the computer. The keyboard is an input unit that produces data bits. Inside the computer you have processors (CPU), random-access memory, semiconductor, hard disk, the bus and the run system. Central Processing Units (CPU) a microprocessor that is, a single piece of silicon containing millions of electrical components. Its input device or memory is communicated through the bus to the CPU, which is the part of the computer that translates commands and runs programs. R am is the physical memory of a computer. You can use it to run programs that look memory to load. The semiconductor is the silicone object used for computer national circuit components. The Bus it the flat cable of numerous wires that joins in with components in the computer. For Example connection to the CPU to the hard disk. The hard disk is where the railway car stores data and programs. When a computer is turned on it searches it memory it is called the operating system. Windows 98 and Mac are forms of operating system.
