When you choose a computer hardware configuration (i.e., the required set of components), you need to immediately decide for what purposes you want to use the computer – for office work or for gaming, for using the Internet or for design work.

Personal computers.

The most popular personal computers are those used at home, in educational institutions, and in the offices of any company. Desktop computers are the most common type of personal computers that have data storage and processing devices, display and sound output devices, and a keyboard located at the workplace.

Gaming computers.

The next category is gaming computers – ordinary computers in which the advanced capabilities of graphics and sound controllers are combined with software limitations and reduced expandability.

Workstations.

Workstations with graphical input and output devices are characterized by high resolution and have the size of desktop computers, with much more computing power than personal computers Used for engineering calculations, in particular for solving computer-aided design tasks.

X-terminals.

X-terminals are a combination of diskless workstations and standard ASCII terminals. Diskless workstations were often used as expensive displays and in this case did not fully utilize the local computing power.

Servers.

Multi-user commercial and business applications, including database management and transaction processing systems, large publishing systems, networking and communications service applications, software development, and image processing are increasingly demanding a shift to a client-server computing model and distributed processing.

Mainframe.

It is synonymous with the term “large universal computer”. Mainframes are the most powerful (excluding supercomputers) general-purpose computing systems that provide continuous round-the-clock operation. When selecting the optimal configuration in the proposed system, after analyzing the classification of computer equipment, the criteria were selected based on the tasks to be processed. Based on this, the optimal criterion is the maximum software requirements that are necessary to perform the tasks to be solved on computer hardware.
