History of the Computer :: essays research papers

In this report, youll about the components and history regarding the computer. A computer is a devise that processes, organize, and calculate, displays information. It plenty communicate with other(a) computers all over the world. The most(prenominal) powerful computer can perform 10s of billion of calculations per second. People practice computers for wadiness, track inventories, and use bar codes, personal home use and other things. Computers can produce information, numbers, images, sounds and movies. Embedded computers control devices such as removed(p) controls.Lets talk about the essential parts of the computer. First you have your outback(a) units like your printer, monitors, modem, floppy platter drive, CD ROM drive, scanner, speakers and keyboard. These things are called peripherals. Printers trace in inkjet, laser and thermal. Lasers are much faster than inkjets. The monitor is the telecasting like unit where you observe text and images. Modems permit us to come to to the Internet, which is a global communication network. Modems come in many assorted speeds. Some are 14.4k, 56k these uses a phone line, cable system modem (in scarcely king-size cities, an internet setup that uses a cable line) and many more than. Floppy disk drives are drives where you insert a disk to save progress or install programs from .CD ROMs are compact 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 info bits. Inside the computer you have processors (CPU), Ram, semiconductor, difficult disk, the bus and the direct system. rudimentary 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 pr ograms. Ram is the physical memory of a computer. You can use it to run programs that require memory to load. The semiconductor is the silicone bearing used for computer inner 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 machine stores data and programs. When a computer is glum on it searches it memory it is called the operating system. Windows 98 and Mac are forms of operating system.
