The Data Processing Center consists of computer and telecommunication systems, as well as additional systems and data storage.
These facilities, called server rooms or system rooms, house servers and data warehouses. Data processing centers are generally divided into two categories: special data processing centers and Internet data processing centers. Special data processing centers serve and are used only by one organization. Data processing centers on the Internet operate to provide data to a third party.
In data processing centers, it varies depending on the seriousness of the protected data and the safety of electrical and mechanical systems. Usually, data processing centers have backup power sources, including backup communication channels, air cooling systems, fire extinguishing systems and protection against possible threats, including appropriate systems depending on the level of data security.

The data processing center was reminiscent of the large computer halls at the beginning of the era of the computer industry. Organizing their operation, maintenance of the first computer systems was a complex process and required special conditions for work. The first computer networks were created by connecting large amounts of cable connections and hardware. This required different procedures and methods. For example, currently, data processing centers use equipment, special racks, raised floors, cable trays, as in the first computer networks. A serious effort was made to ensure cooling so as not to overheat a host. Security was very important because the rather expensive computers were used for military purposes. Permission to process critical data and access to the computer room was required in the centers. At that time, especially in the 1980s, when the microprocessor industry developed, computers began to appear everywhere, but the demand for them was abandoned in many business processes. However, companies have realized the need to manage information resources in improving information technology performance. The client-server model, a network architecture, began to replace the old computer halls in the 1990s with the development of microprocessors (now called servers). As the cost of network equipment became affordable, new standards were set for structured cabling networks, which made it possible to create a hierarchy of servers located in private rooms in workplaces. The term "data processing center", which is a specially designed computer room, is one of the widely used terms today.
