ADVANTAGE AND DISADVANTAGE OF WIRING SCHEMES:
Each of three wiring procedure has disadvantages and advantages, which are illustrate as follows:
RELIABILITY ISSUES:
Wiring that needs a transceiver for every connection does not affect the whole network if a transceiver cable is not connected. A cable cut happening in hub wiring only affects one device.
COST ISSUES:
Twisted pair Ethernet is the cost effective wiring that creates it so popular. Thicknet is the most expensive wiring, which is not used.
Figure
As given in the diagram eight offices are wired with
a) Thick Ethernet b) Thin Ethernet c) Twisted pair Ethernet
We may see that the length of wired varies in three procedures so cost varies in three methods.
Physical layers defines with synchronizing the 1s and 0s on the wire.
