Parts of the Computer

• The parts can be seperated into two categories: – Peripherals – Internal Components

Peripherals A computer peripheral is any external device that provides input and output for the computer. Ex: A keyboard and mouse are input peripherals, while a monitor and printer are output peripherals. Computer peripherals, or peripheral devices, are sometimes called "I/O devices" because they provide input and output for the computer.

Internal Components Internal components are those that reside inside the computer. Some examples are: -Motherboard -CPU -Memory -Video. Cards -Networks Cards -Disk Drives -Bus

Motherboards • Every part of the computer connects to the motherboard in some way. • Some parts are connected directly to it. Others rest on top of it.

Central Processing Unit • The central processing unit is the chip in the computer that does most of the processing. • It can be divided up into 3 categories – Arithemetic Logic Unit – Control Unit – Registers

CPU (cont)

Memory There are several different types of memory storage devices • Hard Drives • Floppy Drives • ROM (Read only Memory) • RAM (Random Access Memory) • EPROM (Erasable Programable ROM)

Bus Peripherals and other internal devices are connected to each other by one or more buses. A bus is a common electrical pathway betweeen multiple devices (hardware). Buses can also be dedicated to special purposes such as connecting to memory or to multiple processors.
