CPU is an abbreviation of Central Processing Unit. the CPU is the brains of the computer, where most calculations take place. On large machines, the CPU requires one or more printed circuit boards. The CPU is inserted directly into a CPU socket, pin side down, on the motherboard. On personal computers and small workstations, the CPU is housed in a single chip called a microprocessor.

Slide 6

A random-access device (RAM) allows stored data to be accessed directly in any random order. There are two different types of RAM: 1. DRAM (Dynamic Random Access Memory). 2. SRAM (Static Random Access Memory). DRAM is a more common type of RAM, while SRAM is mostly used for speed.

Slide 7

A graphics card/video card, is a piece of hardware installed in a computer that is responsible for rendering the image on the computers monitor or display screen.

Slide 8

The computer's sound card performs a similar function as the display, though it can input audio as well as produce sound.

Slide 9

A memory card reader is a device, typically having a USB interface, for accessing the data on a memory card e.g. CompactFlash (CF), Secure-Digital (SD) or Multi-Media- Card (MMC).

Slide 10

A hard drive is the place where all your data is stored. It houses the hard disk, where all your files and folders are physically located. A typical hard drive is only slightly larger than your hand, yet can hold over 100 GB of data.

Slide 11

Network Interface Card (NIC for short) is also commonly known as an Ethernet card or network adapter It is an expansion card that enables a computer to connect to a network (e.g. home network, the Internet[using an Ethernet cable with a RJ-45 connector.])

Slide 12

Also referred to as a surge suppressor. It is a plug-in device that is designed to help protect the computer from surges and spikes.
