A computer network, two or more computers connected together to send information electronically. In addition to connecting computers and physical communication devices, network systems play an important role in establishing connected connections that allow different types of applications to transmit information seamlessly. on the other hand. Two well-known building blocks are ISO Open Systems Interconnection (OSI) and IBM Systems Network Architecture (SNA).
The two types of networks are local area networks (LANs) and
local area networks (WANs). LAN connects computers and external devices to
small physical areas, such as factories, labs, or colleges, through data
(wires, Ethernet cables, optical cables, Wi-Fi) to transmit data. fast. This
type of LAN has two or more computers, printers, and disk storage devices with
advanced capabilities called file servers, which allow any computer on the
network to access a single file. LAN software, which defines and manages
network devices, allows users to communicate; printing departments and storage
facilities; and at the same time access to central processors, data or programs
(management systems). LAN users can also access other LANs or log in to the
WAN. LANs with similar building blocks are connected by a “bridge,” which acts
as a transition point. LANs are connected to different building blocks through
a “gateway,” which transmits data as it passes between systems.
