  7. 1 A Simple Network

  8. 1 Characteristics of a computer network • Share Resources from one computer to another • Create files and store them in one computer, access those files from the other computer(s) connected over the network • Connect a printer, scanner, or a fax machine to one computer within the network and let other computers of the network use the machines available over network.

  9. 1 Advantages of a Computer Network.

  11. 1 Following is the list of hardware's required to setup a computer network. • Network Cables • Distributors • Routers • Internal Network Cards • External Network Cards

  12. Basic Components of a Network • Server: In computer networking, a server is a computer designed to process requests and deliver data to other (client) computers over a local network or the Internet.

  13. Basic Components of a Network • Workstation: A typical workstation is a computer that is configured with a network interface card, networking software and the appropriate cables.

  14. Basic Components of a Network • Hub: Hub is a device that splits a network connection into multiple computers. It is like a distribution center.

  15. Transmission Channels • Computer in a network is interconnected through transmission channels. • These channels can be wired(cables) and wireless(satellites).

  16.  Computer Network Types • PAN:A personal area network (PAN) is a computer network used for data transmission amongst devices such as computers, telephones, tablets and personal digital assistants.

  17. LAN: - LAN networks connect computers together over relatively small distances, such as within a single building or within a small group of buildings.

  18. WAN: - WAN networks connect computers together over large physical distances.

  19. MAN: -This is a network which is larger than a LAN but smaller than a WAN, and incorporates elements of both. It typically spans a town or city and is owned by a single person or company, such as a local council or a large company.
