1. Twisted Pair - is the most common type of cable            a. STP - Shielded Twisted Pair                        -  .   Shielded cables can also help to extend the maximum distance of the cables.            b. UTP - Unshielded Twisted Pair                         -  is the most popular and is generally the best option for school networks .  2.Coaxial Cable -  Coaxial cabling has a single copper conductor at its center. A plastic layer provides insulation between the center conductor and a braided metal shield. The metal shield helps to block any outside interference from fluorescent lights, motors, and other computers.   3. Fiber- Optic Cable -  consists of a center glass core surrounded by several layers of protective materials.

What are the types of Network Topology?

1. Linear Bus Topology -  In networking a bus is the central cable -- the main wire -- that connects all devices on a local-area network ( LAN ). It is also called the  backbone . This is often used to describe the main network connections composing the Internet.  Bus networks are relatively inexpensive and easy to install for small networks.  Ethernet systems use a bus topology. 2. Star Topology -    In a star network devices are connected to a central computer, called a hub. Nodes communicate across the network by passing data through the hub. 3. Ring Topology -    A local-area network ( LAN ) whose topology is a ring. That is, all of the nodes are connected in a closed loop. Messages travel around the ring, with each node reading those messages addressed to it.  4. Mesh Topology -  In a mesh network, devices are connected with many redundant interconnections between network nodes.   5.  Hybrid topology  -  In a tree network, groups of star-configured netwo

A LAN is very useful for sharing resources, such as data storage and printers. LANs can be built with relatively inexpensive hardware, such as hubs, network adapters and Ethernet cables. MAN - Metropolitan Area Network           -    consists of a computer network across an entire city, college campus or small region. A MAN is larger than a LAN, which is typically limited to a single building or site. Depending on the configuration, this type of network can cover an area from several miles to tens of miles.
