Central Processing Unit : 

Central Processing Unit The Central Processing Unit is a machine that can execute computer programs. It is sometimes referred to as the brain of the computer. The CPU is made up of 5 basic features

CPU : 

CPU RAM (random access memory) : This is a form of computer storage, Made up of integrated circuits which can be accessed in any order. Which is why it is called random. REGISTER: is a special type of memory which is quickly accessed.

CPU : 

CPU BUSES : The buses are the information highway for the CPU which carry data words in parallel on multiple wires, which carry data in bit-serial form. ALU (Arithmetic logic Unit : The alu performs the mathematical calculations for the CPU, and is fundamental in the development of the CPU.

CPU : 

CPU Control Unit: The control unit is the circuitry that controls the flow of information through the processor.

Von Neumann Architecture : 

Von Neumann Architecture Named after the computer scientist john von Neumann. Is a design model for a stored that uses a central processing unit (CPU) And a single separate storage structure to hold both instructions and data.

Northbridge Chip : 

Northbridge Chip The northbridge is one of the two chips in the core logic chipset on a pc motherboard, the other being the southbridge. The northbridge typically handles communications among the CPU, RAM, BIOS, ROM, and PCI Express (or AGP) video cards.

Southbridge Chip : 

Southbridge Chip The Southbridge can usually be distinguished from the Northbridge by not being directly connected to the CPU. It is given responsibility for the slower devices on a typical microcomputer.

Fetch and Execute Cycle : 

Fetch and Execute Cycle Also known as, an instruction cycle or fetch and decode cycle or FDX. It is the process by which a computer receives instructions from its memory. It does four tasks, fetch the instructions, decode the instructions, execute and finally store the results.
