WHAT IS INSIDE OF COMPUTER?


        The base of operations for the brains of a computer is the motherboard. The motherboard serves as a literal foundation for many of the other elements inside your computer. It's a large printed circuit board. The motherboard provides the connections and sockets that let other components communicate with each other. Motherboards come in different shapes and sizes -- a motherboard in a laptop computer might not look like one from a desktop PC.

The computer brain is a microprocessor called the central processing unit (CPU). The CPU is a chip containing millions of tiny transistors. It's the CPU's job to perform the calculations necessary to make the computer work -- the transistors in the CPU manipulate the data. You can think of a CPU as the decision maker.

Another critical component in computers is memory. The two most important kinds of memory are read-only memory (ROM) and random access memory (RAM). Computers can read data stored in ROM, but can't write new data to it. With RAM, computers can read from and write to that memory. Without computer memory, every calculation on a computer would be stateless. That means there'd be no way to preserve information from one moment to the next and every process would start on a clean slate. That's not useful if you want to create complex programs.
