Posted: September 11th 2012

Komputer hardware ( perangkat keras / umumnya revileral )

Hardware Components

> the hardware components of amd information system :

– CPU ( central processing unit / system unit )

– Memory / Ram ( primary and secondary stroge )

– Input devies

Two main components on the motherboard

central processing unit ( CPU )

also called a processor

=> Membawa data , memproses dan menghasilkan data hasilnya adalah output.

Memory (menyimpan data) sebelum di proses di simpan dahulu di dalam memory

> procesor

> memory

– adapter card

– sound card

-modem card

– network card

> ports

> power supply

Dual Inline Packages ( DIP ) holds memory Chips

pin Grid Array ( PGA ) package holds processor chips.

CPU : adalah mengakses program dan mengatur aliran data

Anthemetik-Logic Unit ( ALU ) : Perform computations / pengaturan data

Register , sebagai alat penyimpan data atau memory yang letaknya lebih dekat dengan primary stroge

Type Of primary stroge

– register – part of the cpu

– random acces memory ( RAM ) , memory chips on motherboard general stroge

– chache memory – faster than ram

pernament instructions need by computer

Basic , input , output system ( BIOS )

secondary memory

– nonvolatile : data hilang ketika daya hilang. sedangkan

– volatile : data tidak hilang ketika daya hilang

 

Satuan Kapasitas :
Killobyte ( KB / K ) : 1 thousand bytes

Megabyte ( MB ) : 1 millions bytes

Gigabyte ( GB ) : 1 billion bytes

Terasbyte ( TB ) : 1 trillion bytes
