Describe the Client-Server architecture.
Answers
Answer:
Two basic network types are local-area networks (LANs) and wide-area networks (WANs). LANs connect computers and peripheral devices in a limited physical area, such as a business office, laboratory, or college campus, by means of links (wires, Ethernet cables, fibre optics, Wi-Fi) that transmit data rapidly.
2.The significant difference between them is the geographical area they cover. When we consider the order, PAN is capable of providing network connection around a person, next comes LAN which covers a smaller area; then comes MAN; it covers an area larger than LAN & WAN is the largest of all.
3.Client-server architecture, architecture of a computer network in which many clients (remote processors) request and receive service from a centralized server (host computer). Client computers provide an interface to allow a computer user to request services of the server and to display the results the server returns
