COMPUTERS & COMMUNICATIONS

Computer hardware

Hardware is a comprehensive term for all of the physical parts of a computer, as distinguished from the data it contains or operates on, and the software that provides instructions for the hardware to acoomplish tasks. The boundary between hardware and software is slightly blurry - firmware is software that is "built-in" to the hardware, but such firmware is usually the province of computer programmers and computer engineers[?] in any case and not an issue that computer users need to concern themselves with.

A typical computer (Personal Computer, PC) contains in a desktop or tower case the following parts:

Motherboard which holds the CPU, main memory and other parts, and has slots for expansion cards

power supply - a case that holds a transformer, voltage control and fan

storage controllers, of IDE, SCSI or other type, that control hard disk , floppy disk, CD-ROM and other drives; the controllers sit directly on the motherboard (on-board) or on expansion cards

graphics controller that produces the output for the monitor

the hard disk, floppy disk and other drives for mass storage

interface controllers (parallel, serial, USB, Firewire) to connect the computer to external peripheral devices such as printers or scanners

Computer software

Computer software (often called just software) is made of one or more computer programs. Sometimes it means one specific program, or it can mean all the software on a computer, including the applications and the operating system. Applications are programs that do a specific thing, such as a game or a word processor. The operating system (Mac OS, Windows 7, Windows XP, Linux, etc) is software that helps the applications run, and controls the display and the keyboard.

INTERNET

The Internet is generally defined as a global network connecting millions of computers. More than 190 countries are linked into exchanges of data, news and opinions. It is a vast computer network linking smaller computer networks worldwide (usually preceded by the). The Internet includes commercial, educational, governmental, and other networks, all of which use the same set of communications protocols.
