4.1.6. Coprocessor dan Sistem Processing lainnya

4.2. Primary Storage

4.2.1. Random Access Memory (RAM)

volatile : dapat ditambah, diubah, dihapus

Jenis-jenis RAM

4.2.2. Cache

4.2.3. Read-only Memory (ROM)

non-volatile : tidak dapat ditambah, diubah, dihapus

ROM menyimpan perintah-perintah BIOS (Basic Input/Output System) yang diperlukan saat boot-up

Jenis-jenis ROM

4.3. Motherboard

Hal-hal yang mempengaruhi efektivitas motherboard:

chipset

bus

expansion slot

peralatan yang onboard

socket

CPU clock / speed. Overclock : menaikkan clock (di luar ketentuan pabrik)

CPU fan

Casing AT/ATX : biasanya pembelian casing beserta power supply

4.3.1. Bus

Jenis-jenis Bus

 

4.3.2. Komputer dan Peripheral

Ports: penghubung antara komputer (mainboard) dengan peralatan tambahan (peripheral)

Specialized ports:

4.4. Peralatan Pendukung

 


http://www.asciitable.com/ : ASCII stands for American Standard Code for Information Interchange. Computers can only understand numbers, so an ASCII code is the numerical representation of a character such as 'a' or '@' or an action of some sort. ASCII was developed a long time ago and now the non-printing characters are rarely used for their original purpose.

http://www.unicode.org/standard/WhatIsUnicode.html : Unicode provides a unique number for every character, no matter what the platform, no matter what the program, no matter what the language. The Unicode Standard has been adopted by such industry leaders as Apple, HP, IBM, JustSystem, Microsoft, Oracle, SAP, Sun, Sybase, Unisys and many others.
