Computers
A computer is a devise that processes, organize, and calculate, displays information. It can communicate with other computers all over the world. The most powerful computer can perform 10s of billion of calculations per second. People use computers for business, 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 remote controls. Lets talk about the essential parts of the computer. First you have your outside units like your printer, monitors, modem, floppy disk drive, CD ROM drive, scanner, speakers and keyboard. These things are called peripherals. Printers come in inkjet, laser and thermal. Lasers are much faster than inkjets. The monitor is the television like unit where you observe text and images. Modems permit us to connect to the Internet, which is a global communication 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 compact disk that can read
Computers are getting doubled the speed about every 18 months. They are getting cheaper because of the rise in competition. The advances of technology enable us to excel in our technical needs. It was studies that children who uses computers, are more likely to do better in school. The computer is defiantly one of man's best creations. Inside the computer you have processors (CPU), Ram, semiconductor, hard disk, the bus and the operating system. Central Processing Units (CPU) a microprocessor that is, a single piece of silicon containing millions of electrical components. It's 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. 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 object 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 turned on it searches it memory it is called the operating system. Windows 98 and Mac are forms of operating system.
