  1. Networks Types Created by: Ghadeer Abosaeed June 21, 2012

  2. Objectives: 1- Students will be able to expand their knowledge in: a- The concepts of networking. b- Networks Types and the differences among them.

  3. What is a network? A network can be defined as two or more computers connected together in such a way that they can share resources. A resource may be: A file A folder A printer A disk drive Or just about anything else that exists on a computer.

  4. Other Definitions and concepts About Networks A network is simply a collection of computers or other hardware devices that are connected together, either physically or logically, using special hardware and software, to allow them to exchange information and cooperate. Networking is the term that describes the processes involved in designing, implementing, upgrading, managing and otherwise working with networks and network technologies.

  5. Computer Network

  6. Basic Networks Types There are many different types of computer networks, however, the most common network types are 1- Local area network (LAN), 2- Metropolitan area network (MAN), 3- and Wide area network (WAN).

  7. Local area network (LAN) • LAN is the most common kind of network set up. • LAN is a group of computers and network devices connected together, usually within the same building. For example an office or home network. By definition, the connections must be high speed and relatively inexpensive. • LANs are usually connected by Ethernet cables and have high speed connections.

  9. Metropolitan area network (MAN) • MAN is a larger network that connects computer users in a particular geographic area or region. For example a large university may have a network so large that it may be classified as a MAN. • MAN network usually exist to provide connectivity to local ISPs, cable TV, or large corporations. • MAN is far larger than a LAN and smaller than a WAN. Also large cities like London and Sydney, Australia have metropolitan area networks.

  11. Wide area network (WAN) • WAN is the largest network and can interconnect networks throughout the world and is not restricted to a geographical location. • Most WANs exist to connect LANs that are not in the same geographical area. • The Internet is the perfect example of WAN. • WAN is high speed and very expensive to setup. • WAN is much more complex and requires connecting devices or hubs from all over the world.
