Top Ansible Interview Questions and Answers [2025 Updated] Computer network. Computers are linked in networks to allow them to exchange information electronically. A computer network connects two or more computers and communication devices. Users can share data, files, or applications on the network as if these resources resided on their respective computers. A network serves the important function of establishing an architecture, or structure, that allows a variety of equipment types to transfer data in a near-seamless fashion.
Two popular architectures are ISO Open Systems Interconnection (OSI) and IBM’s Systems Network Architecture (SNA). To function properly, the network must have a set of established protocols—standardized rules for the format and exchange of messages. These protocols allow the linked computers and devices to interpret the signals they receive and to engage in meaningful “conversations” in order to accomplish tasks on behalf of users. Two basic network types are local area networks (LANs) and wide area networks (WANs). 7 Types of Network Topology Explained with Diagrams. «Network Hardware Devices | Router, Hub, ...
