A general purpose computer has four main components: the arithmetic and logic units (ALU), the control unit, the memory, and the input and output devices (collectively termed I/O). These parts are interconnected by busses, often made of groups of wires.
The control unit, ALU, registers, and basic I/O (and often other hardware closely linked with these) are collectively known as a central processing unit (CPU). Early CPUs were composed of many separate components but since the mid-1970s CPUs have typically been constructed on a single integrated circuit called a microprocessor.

Computer systems can be discussed in two parts: hardware and software. The hardware is physical, electronic, and electro-mechanical devices. The hardware consists of Central Processing Unit (CPU), input devices and output devices. Input devices are used to provide data for the CPU. The keyboard is a common data input device. Data is sometimes entered on cards. The cards are read by an input device called a card reader. Output devices receive data from the CPU. The visual display unit (VDU) and printers are common output devices. Input devices, output devices and mass storage devices are collectively called Input-Output Devices, or peripherals. The software contains the programmes that control and coordinate the activities of the computer hardware and direct the processing of data.

Programming software usually provides tools to assist a programmer in writing computer programmes, and software using different programming languages in a more convenient way. The tools include:
– compilers;
– debuggers;
– interpreters;
– linkers;
– text editors.
IDE or Integrated Development Environment is a single application that attempts to manage all these functions.

In the world there are a lot of network operating systems. Among the most successful systems are Unix, Novell NetWare and Windows NT Server. All these systems can restrict the rights of customers’ file servers to allocate resources of the workstations. Each of these systems meet the criteria of safety, reliability and most importantly – security.

The computer network (computer network, data network) is a system of communication between two or more computers and/or computer equipment (servers, printers, fax machines, routers and other equipment). Transferring of information can be done by various physical phenomena, as a rule by various types of electrical signals or electromagnetic radiation.

CPUs contain a special set of memory cells called registers that can be read and written much more rapidly than the main memory area. There are typically between two and one hundred registers depending on the type of CPU. Registers are used for the most frequently needed data items to avoid having to access the main memory every time data is needed. As data is constantly being worked on, reducing the need to access main memory (which is often slow compared to ALU and control units) it greatly increases the computer speed.
