The differences between LAN - Local Area Network and WAN - Wide Area Network is as follows: LAN (Local Area Network) 1. LAN - Local Area Network is used to connect computers at one place, in one room or a building. 2. LAN - Local Area Network covers small and limited area. 3. Data transfer speed is very fast in LAN because of small distance. 4. Local Area network speed is normally form 1 to l00 Mbps. 5. LAN - Local Area Network is less costly. 6. LAN - Local Area Network is usually connected through wires. 7. Normally, the    connection     in     a     LAN - Local Area Network   is permanent using wires. 8. LAN - Local Area Network is used for sharing data, information, files and hardware like printers, hard disk, modem etc. 9. LAN - Local Area Network has    less    possibility    of data transmissio

Explain different types of computer networks:(LAN,WAN,MAN) Today, we will discuss the main types of computer networks on the basis of the maximum distance covered where they can be accessed and operate. The main types of computer networks are: LAN, WAN, MAN Explain different types of computer networks 1.    LAN - Local-Area Network 2.    WAN - Wide-Area Network 3.    MAN - Metropolitan-Area Network 1)LAN (Local Area Network) What is LAN or Local Area Network LAN stands for Local Area Network . It covers a small area. Most LANs are used to connect computers in a single building or group of near buildings. A network contained within a relatively small area, such as a classroom, school, or single building, is commonly referred to as a local area network. Hundreds or thousands of computers may be connected through LAN . LANs are used in office buildings, college or university campus etc. Local Area Networks can transfer data at a very high speed.

Define Network with examples. Give importance of Computer Network. COMPUTER NETWORK We can define a Computer Network as a set of two or more connected computers to share information and other resources (data, files, printers, hard disk, modem, CD-Rom Drive, CD-Writer, DVD-Rom Drive, DVD-Writer etc.). The computers in a network can share: Data, Information, Files Software Hardware (printers, disk, modems)etc. Advantages of Computer Networks EXAMPLES OF COMPUTER NETWORK Computer network can be used in an office. Different people in the office can share common information and printer. Net Cafes use Computer Network for internet sharing. Net Cafe Owners can save money by sharing one DSL Routers / Modem and a single Internet Connection. Computer Network is used in Computer Laboratories of Schools, Colleges and other educational institutes. Internet, is also an example of a computer network. Internet is a network of millions of computers connected through phone lin
