Computer Hardware terdiri dari :
- CPU (central processing unit)
- Memory (primary and secondary storage)
- Input devices
- Output devices
1. CPU terdiri dari :
B. Motherboard
-
Main circuit board in system unit
-
Contains adapter cards, processor chips, and
memory chips
-
Also called system boar
2. Memory :
A. Primary Storage
-
Register – berkecepatan tinggi; kapasitas terbatas
-
Random Access Memory (RAM) – volatile (jika cartur daya hilang, maka data akan hilang)
-
Cache Memory – penyimpanan sebelum ram RAM
-
Read-only Memory (ROM) – non volatile
B. Secondary Memory
- Hard Disck
- CD
- DVD
- Flas Disc
Bersifat non volatile, biasa nya di gunakan untuk menyimpan data
biasa nya di hitung menggunkan satuan “Kilobytes, Megabytes, Gigabytes, Terabytes”
8 bits = byte
Kilobyte (KB or K) 1 KB –> 1,000 bytes
Megabyte (MB ) 1 MB –> 1,000,000 bytes
Gigabyte (GB ) 1 GB –> 1,000,000,000 bytes
Terabyte (TB) 1 TB –> 1,000,000,000,000 bytes
