Network connectivity describes the extensive process of connecting various parts of a network to one another, for example, through the use of routers, switches and gateways, and how that process works.Network connectivity is also a kind of metric to discuss how well parts of the network connect to one another. Related terms include network topology, which refers to the structure and makeup of the network as a whole.
A data center is a repository that houses computing facilities like servers, routers, switches and firewalls, as well as supporting components like backup equipment, fire suppression facilities and air conditioning. A data center may be complex (dedicated building) or simple (an area or room that houses only a few servers). Additionally, a data center may be private or shared.
Data center components often make up the core of an organization’s information system (IS). Thus, these critical data center facilities usually require a significant investment of supporting systems, including air conditioning/climate control systems, fire suppression/smoke detection, secure entry and identification and raised floors for easy cabling and water damage prevention.
