Computer network, at least two PCs that are associated with each other to impart information electronically. Other than truly associating PC and specialized gadgets, a system framework serves the significant capacity of setting up a strong design that permits an assortment of gear types to move data in a close consistent manner. Two mainstream designs are ISO Open Systems Interconnection (OSI) and IBM's Systems Network Architecture (SNA).

Two essential system types are neighborhood (LANs) and wide-region systems (WANs). LANs associate PCs and fringe gadgets in a restricted physical territory, for example, a business office, lab, or school grounds, by methods for joins (wires, Ethernet links, fiber optics, Wi-Fi) that transmit information quickly. An ordinary LAN comprises of at least two PCs, printers, and high-limit circle stockpiling gadgets called document servers, which empower every PC on the system to get to a typical arrangement of records. LAN working framework programming, which deciphers input and educates organized gadgets, permits clients to speak with one another; share the printers and capacity gear; and all the while get to midway found processors, information, or projects (guidance sets). LAN clients may likewise get to different LANs or tap into WANs. LANs with comparable models are connected by "spans," which go about as move focuses. LANs with various structures are connected by "portals," which convert information as it goes between frameworks.
