3.2. Network topology 3.2.1. Network topology in general There are many network topologies which are point to point which is stranded lan between 2 or more pcs using cat 5 or 6 cables to connect them. Bus used coax and connected a series of computers on a shared line but if devise fails they all fail also this topology is no longer used since the introduction of Cat 5 and higher cables. There is ring topology where computers are connected to each other and a virtual token is used to allow pcs to

Amor, John Anthony Y. Mr. Lopez BSIT-1A CRITIQUE PAPER Transmission Media is the physical path between transmitter and receiver. The transmission media that are used to convey information can be classified as guided or unguided. Guided media provide a physical path along which the signals are propagated; these include twisted pair, coaxial cable, and optical fiber. Unguided media employ an antenna for transmitting
