Data Communication and Networking
Task 1: Define following network terminologies:
EIA/TIA 568A and 568B standards:
568A and 568B are the standard colour codes for telecommunication
standards. Although there is no such difference between both. They just
differ in he placement of orange and green wires. They are helping in
creating crossover wire and straight-thru wire. If one end is 568A and other
is 568B its called crossover while if both ends have same standard that will
be known as straight-thru.
Colour combination of straight and cross Ethernet cable
There are 2 colour combinations known as 568A and 568B respectively in
which placement of green and orange are switched only.
For Straight-thru: both ends of the wire needs to be the same standard either
568A or 568B. While, For Crossover: both end of the wire needs to be
different standards means if one side is 568A than other needs to be 568B.
Unshielded Twisted Pair (UTP) & Shielded Twisted Pair (STP)
Unshielded Twisted Pair is the type of twisted pair cable which does not
have extra coating and it is relatively cheaper than STP and it transfer low
Data rate than STP. While STP is a costly twisted pair cable, it requires more
maintenance than the UTP.
Straight Through and Cross-over Ethernet Cable
Straight Through Wires are the cables in which both ends of the cable have
same pattern of pins. This is most common type of connection used for
client-host connection. It is also used to connect peripherals like printer,
router, etc to the computer.
Cross-over wired cables are somewhat opposite to straight-through in which
both ends of the cable are different standards i.e. 568A and 568B. This
method is used to connect two hosts directly which is computer to computer.

cables (setting up ethernet cable wiring)
