Data and Communications Center
A data center (American English) or data center (British English) is a building, a dedicated space within a building, or a group of buildings  used to house computer systems and associated components, such as telecommunications systems. and storage.
Because IT operations are critical to business continuity, it typically includes redundant or backup infrastructure and components for power supply, data communications connections, environmental controls (eg, air conditioning, fire suppression), and various devices. of security. A large data center is an industrial-scale operation that uses as much electricity as a small city.
Communications and Infrastructure Implementation
Data centers have their roots in the huge computer rooms of the 1940s, typified by ENIAC, one of the earliest examples of a data center. The first computer systems, complex to operate and maintain, required a special environment in which to operate. Many cables were required to connect all the components, and methods were devised to accommodate and organize them, such as standard equipment mounting racks, raised floors, and cable trays (installed above or below the raised floor). A single mainframe required a large amount of power and had to be cooled to avoid overheating. Security became important: Computers were expensive and often used for military purposes. Therefore, basic design guidelines were devised to control access to the computer room.
Information Technology Operations
During the boom in the microcomputer industry, and especially during the 1980s, users began to deploy computers everywhere, in many cases with little or no concern for operational requirements. However, as information technology (IT) operations began to grow in complexity, organizations became aware of the need to control IT resources. The advent of Unix from the early 1970s led to the subsequent proliferation of Linux-compatible PC operating systems available for free during the 1990s. These were called “servers.” since timesharing operating systems like Unix rely heavily on the client-server model to facilitate the exchange of unique resources between multiple users.The availability of inexpensive network equipment, along with new standards for structured network cabling, made it possible to use a hierarchical design that places servers in a specific room within the enterprise. The use of the term “data center”, applied to specially designed computer rooms, began to gain popular recognition during this time.
