Actually, it is a heart of computer. Other system elements are connected to motherboard, and the whole system is managed and controlled by it. Motherboard contains special chips on which some ICs (Integrated circuits) are etched. Processor  – a computer engine, its brain. CPU (central processing unit) manages most of computer operations. Processors can be with pins or pin-less. It contains a control unit and a logic unit. RAM  (random access memory) – primarily memory. It storages all data processed by programs and apps on the computer.
