Because data is not stored on workstations locally. This will help users to use any workstation in a network to access their data. Centralized Data: The data of all network users can be saved on hard disk of the server computer.Easy and Cheap Communication: Data and messages can easily be transferred over networked computers.
TYPES OF NETWORK SOFTWARE
Software Applications Sharing: It is cheaper to use same software over network instead of purchasing separate licensed software for each client a network.This reduces cost and hardware purchases. Resource Sharing: Computer resources like printers, modems, DVD-ROM drives and hard disks can be shared with the help of local area networks.Sharing common resources like printers etc are some common applications of LAN.Connecting Locally all the workstations in a building to let them communicate with each other locally without any internet access.Software can be stored on the server and it can be used by the remaining clients. One of the computer in a network can become a server serving all the remaining computers called clients.they work in a restricted geographical area. It connects computers in a single building, block or campus, i.e.There are different types of Media Access Control methods in a LAN, the prominent ones are Ethernet, Token ring.LAN's operate at relatively high speed when compared to the typical WAN.LAN's are private networks, not subject to tariffs or other regulatory controls.LAN networks are also widely used to share resources like printers, shared hard-drive etc. LAN can be a simple network like connecting two computers, to share files and network among each other while it can also be as complex as interconnecting an entire building. We can use different types of topologies through LAN, these are Star, Ring, Bus, Tree etc. Personal computers and workstations are connected to each other through LANs. LANs are used widely as it is easy to design and to troubleshoot. It is also called LAN and designed for small physical areas such as an office, group of buildings or a factory. Difference between OSI and TCP/IP ModelĬommunication Networks can be of following 5 types:.TCP/IP REFERENCE MODELCOMPUTER NETWORKS.Connection Oriented and Connectionless Services.
