[object Object],[object Object],[object Object],[object Object],Star Network Topology The network is configured in the shape of a star with all nodes or workstations connected to a central hub, through which all messages pass

[object Object],[object Object],[object Object],Bus Network Topology The network is configured in the shape of an open-ended line with all nodes or workstations connected to the bus individually.

[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Ring Network Topology The network is configured in the shape of a circle with each node connecting to the next node. Messages travel around the circle in one direction. Each node examines the message and uses it or regenerates it and passes it to the next node

Twisted Pair Two or more pairs of insulated copper wires twisted together; may be shielded (STP) or unshielded (UTP). It has the lowest capacity of the cable options ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Coaxial Cable Contains a solid inner copper conductor surrounded by insulation and outer braided copper or foil shield . It comes in different thicknesses and is higher capacity than twisted pair ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Microwave A high frequency radio signal that is sent through the air using either terrestrial (earth-based) or satellite systems Terrestrial Microwave - A line-of-site technology (unobstructed) used to cross inaccessible terrain or to connect buildings where cable installation would be expensive. Attenuation is low over short distance but higher over longer distances. High winds , heavy rain , EMI and eavesdropping are also problems.

Satellite Microwave - A line-of-site technology that uses relay stations to transfer signals between antennae located on earth and a satellite orbiting the earth . It can be used to access very remote locations and like terrestrial microwave, attenuation , EMI and eavesdropping are also problems
