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 [3] 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.

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.
