The monitor (display) displays information on the screen in the form of text and various images. The keyboard enters commands and various information into the computer. Often, a computer includes a "mouse" manipulator and a printer. A "mouse" is a device with two or three knobs (buttons) that facilitate computer work. The printer serves to print information on paper. Modern computers mainly consist of four devices: control, processor, memory and input-output devices. The controller coordinates and controls the operation of all the computer's devices. The processor is the main device of the computer, which processes information, that is, performs arithmetic and logical operations such as calculation operations, comparison and transfer. The actions performed by this device are determined by programs. A memory device serves to store information during processing. The used programs are stored in the internal memory, and long-term information is stored in the external memory (diskettes). Information exchange in internal and external memories is carried out using input - output devices.
