RAM (Random Access Memory) is system's short-term memory or Primary memory. RAM is used by the system to store data that is processed by a computer's CPU. Higher more RAM you have, the more things your computer can do at the same time, and the faster your computer performs certain tasks.

PROCESSOR•ACT AS PROCESSING DEVICE OF COMPUTER

e.g.:- INTEL CORE 7i ; INTEL CORE 3i ; INTEL CORE 2 dual ; INTEL DUAL CORE ; ATOM; AMD

The processor is the central focus of the computer. It has three main tasks:

1. Receiving input (including memory access)2. Giving output (including memory access)3. And performing mathematical and logical calculations
