MAIN MEMORY
According to Intel: Input, Output, Processing and Storage. Input devices send data and instructions to the central processing unit. Processing executes computer instructions. Memory holds data and programs temporarily. Output devices make processed data available to the user. Storage devices store data and programs permanently.

The system unit is the box where all processing takes place. All other devices are attached to it. The Central Processing Unit (CPU) is the heart of the computer, and is inside the system unit.
• The processor fetches the instruction from memory • Program counter (PC) holds address of the instruction to be fetched next • PC is incremented after each fetch • Fetched instruction loaded into instruction register
The CPU is usually located on the motherboard.
Mother board.
the storage
The Hard Drive is the main storage unit in a normal, desktop computer. This is the only internal component in a standard computer that has information when the machine is turned off (all your saved files, the operating system (such as Windows), etc). There are other components (such as RAM, or Random Access Memory) that store data, but this usually serves a special purpose, or is only at run-time.
The instruction register holds a pointer to the current instruction (in working memory) while the next instruction register points to the next instruction (the first instruction immediately after the current instruction's operands). If the current instruction is a jump instruction, it can change the next instruction register, allowing the program to branch to a new instruction once the jump instruction is processed. The next instruction pointer is automatically moved into the current instruction register once the current instruction has been processed. The entire process of executing an instruction is known as the fetch-decode-execute cycle.

Input devices sends data to the central processing unit. Central processing unit (CPU) excutes computer instructions. Memory holds data and programs currently in use. In the same time secondary storage devices stores data and programs. Lastly output devices make processed data (information) available.
A central axis is part of a computer system or other electronics. It is a freestanding box that holds data for these electronics.
