The Motherboard

- its the principal item inside the computer

- the main circuit board in the computer where

everything comes together

- processor and memory chips must be compatible

- main job: connecting the individual parts with each other

The Processor (CPU (Central Processing Unit))

- brain of the PC

- absolutely necessary

- executes all important instructions

- speed (MHz) is very important

- can be upgraded

Main Memory


10/26

- its the short-term brain of the computer

The Main Memory (RAM ( Random Access Memory))

- if you switch the computer on, all the information is put

into the RAM-section

- the processor loads the data, which are frequentlyused, into the main memory

- RAM-section is important for the processing-speed

- if additional memory is available, the computer is

much faster

- data in the main memory can be read muchfaster than on the hard disk

Hard Disk

- its a long-term storage

- you can store operating systems, programs and other

data on it

- its very shock sensitive

- it has got a big memory volume

The Graphics Card

- responsible for display output

- nowadays usually in AGP standard

- determines the display resolution, the number of differentcolours and the frame speed

The Floppy Disk Drive

- available in each standard computer

- for removable floppy disks to read and write data

- makes only sense for files with a small size (max. 1.44 MB)

- slow access
