Some Internal Parts • SYSTEM UNIT: contains all components of the computer system (casing for entire computer system)

• POWER SUPPLY: computer’s power supply (plug) and cooling system (fan)

• RANDOM ACCESS MEMORY (RAM): Computer’s “temporary” memory used to run programs

• MOTHER BOARD: main computer board – all other cards and chips plug into it

• PERIPHERAL CARDS: Cards that allow “extra” components to be added to the computer system (i) Sound Card – allows speakers to be added (ii) Video Card – allows games, videos, graphics to be used

(iii) Modem Card – (allows internet & e-mail access) (iv) Network Card – (allows you to connect multiple computers) (v) Scanner Card – (allows you to enter hardcopy documents / pictures into the computer) (vi) Scuzzy Card – (SCSI) (allows you to add extra “external” memory)

• CPU (CENTRAL PROCESSING UNIT): processor chip (computer’s brain)

• CD ROM DRIVE: allows CD software to be run

• CD ROM: programs stored in CD format

FLOPPY DISK: “permanent” memory

• HARD DRIVE (LOWER COMPONENT): Computer’s “internal” storage stores software (programs)

Finally it’s over! It’s time for a quiz…wake up if you were sleeping!
