1central processing unitA central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.
2fetch,decode & execute cycleThe Central Processing Unit (CPU) is the brain of the computer. It is the component that does all of the clever calculations. It reads the instructions in a program, decides what to do about each instruction and then sends out signals to all of the different pieces of hardware to make things happen.
3Random-access memory (RAM)Random-access memory (RAM /ræm/) is a form of computer data storage. A random-access memory device allows data items to be accessed (read or written) in almost the same amount of time irrespective of the physical location of data inside the memory.
4read only memory (ROM)Read-only memory (ROM) is a class of storage medium used in computers and other electronic devices. Data stored in ROM can only be modified slowly, with difficulty, or not at all, so it is mainly used to distribute firmware (software that is very closely tied to specific hardware, and unlikely to need frequent updates).
