TVV Group

Components

• Peripheral Component Interconnect

• from 1 up to about 6 slots on a motherboard

• run at 33Mhz and normally 32bits

• support plug and play

PCI Slots

TVV Group

Components

• Industry Standard Architecture

• connect internal peripherals such as modems and network cards

• run at only a 8Mhz maximum

ISA Slots

TVV Group

Components

• group of integrated circuits

• divided into different parts

• each part provide specific functions

Chipset

TVV Group

Components

• links the motherboard to the CPU(s)

• built around the pin grid array (PGA) architecture

CPU Socket

TVV Group

Components

• Complementary metal–oxide–semiconductor

• gives the board a small amount of power

• store some vital data (e.g. time, date, settings, etc)

CMOS

TVV Group

Components

• 2 PS/2 connectors: for mouse and for keyboard

• same size, same shape, different colours

• not interchangeable

PS/2 Connectors

TVV Group

Components

• connect external components

• change the devices without switching the power off

USB Ports

IV - History

TVV Group

History

• In 1947 the first transistor was invented

• CPU, memory and I/O peripherals were housed on individual PCBs

• In 1980s, motherboards began to include single ICs

• At present, motherboards support a full range of audio, video, storage, and networking functions
