  Computer Introduction : A computer is an electronic device that can store, retrieve, and process data. It can be used for a wide variety of tasks, including word processing, playing games, and creating and editing images. Computers typically consist of a central processing unit (CPU), memory, storage, and input/output (I/O) devices. Cpu : A CPU (Central Processing Unit) is the main component of a computer system. It is responsible for carrying out instructions and performing calculations. It is the "brain" of the computer, and is responsible for controlling all of the other components. Ram : RAM (Random Access Memory) is a type of computer memory that can be accessed randomly, meaning any byte of memory can be accessed without touching the preceding bytes. RAM is used to store data and programs that are currently in use. It is much faster to read from and write to than other kinds of storage, such as a hard disk drive, solid-state drive, or optical drive. Rom ...
