    • Advantage and Disadvantage of Networking
  • 4. Introduction :- Definition :- Networking is the practice of linking two or more computing devices together for the purpose of sharing data . Networking
  • 5. History :-
    • In 1967 APRA proposed an idea to develop a small network of connected computer called APRANET .
    • In this network each computer was connected to a specialized computer called an Interface Message Processor (IMP) .
    • In 1969 APRANET was implemented .four computer at different geological location through the IMP S .
    • In 1980 U.S. NSF started exploring ways to enable access of their supercomputer to researchers at various college and Uni.
    • The NSF developed a network called the National Science Foundation Network (NSFNET) .
    • In 1990 Tim Berners-Lee Created the World Wide Web ( WWW )
    Networking
  • 6. Need for Networking :- Networking
    • Resource Sharing ,aim is to make data ,program available to anyone on the network.
    • Reliability , file can be replicated on two or three machines if one them is unavailable the other can be used.
    • Financial Benefit , networking of PC is batter rather then centralized large computer .
    • Better Communication Medium , it is possible to transfer instantly any information to any other destination .
  • 7. Hardware Required for Networking :- Networking
    • Network cards : such as this one can transmit and receive data at high rates over various types of network cables . This card is a 'Combo' card which supports three cabling standards.
    • Network adapter : interfaces a computer board with the network medium.
    • Router : links two or more networks.
    • Hub : multi-port repeater .
    • Switches :bridging technology to forward traffic between ports.
  • 8.
    • Modem : A modem is a computer peripheral that allows you to connect and communicate with other computer via telephone lines .
    Modem
    • There are four principal media for telecommunications
    • Coaxial Cable
    • Twisted Pair Cable
    • Optical Fiber
    • Wireless
    Networking
  • 9. Networking Method :- Networking 1. Local Area network(LAN) 2.Wide Area Network(WAN) WAN Devices One way to categorize computer networks is by their geographic scope
    • A local area network is a network that spans a relatively small space and provides services to a small number of people.
    • The first LAN was invented by a Law Doctor in 1978 .
    • A wide area network is a network where a wide variety of resources are deployed across a large domestic area or internationally
    • Example :- Internet
  • 10. 3.Metropolitan Area Networks(MAN) 4.Wireless Networks (WLAN, WWAN) Networking
    • A metropolitan network is a network that is too large for even the largest of LAN's but is not on the scale of a WAN .
    • Example :- City
    • A wireless network is basically the same as a LAN or a WAN but there are no wires between hosts and servers .
    Wireless
  • 11. Networking Topology :- Networking
    • The network topology defines the way in which computers, printers, and other devices are connected, physically and logically .
    • Bus
    • Star
    • Tree (hierarchical)
    • Ring
    • Mesh
    • Fully connected
    • Partially connected
    BUS STAR TREE RING
  • 12. Application of Networking :- Networking
    • E - mail Service
    • Locating sites using search engines
    • Finding People on the Net
    • Chat
    • Video Conferencing
    • E-Commerce

    • Requires Administrative Time . Proper maintenance of a network .
    • File Server May Fail when the files server "goes down ," the entire network may come to a halt .
    • Cables May Break broken cable can stop the entire network .
    • Networking can be a waiting game where you have to wait it out patiently for the right opportunity or the right contact to come available .
