(i) Patch cable [Twisted pair]
(ii) RJ45 connector
(iii) Ethernet ports
(iv) Crimping tool

(i) A cable interconnecting two devices directly is known as a null modem cable.
(ii) The crossover Ethernet cable is an example of the null modem cables.

S.No	Serial Port	Parallel Port
1.	It transmit the data one bit at one time.	It transmit the data 8-bit at one time.

(v) These plugs (connector) are inserted into Ethernet port of the network card.

(i) If you require a cable to connect two computers or Ethernet devices directly together without a hub, then you will need to use a Crossover cable instead.
(ii) Here, the pairs of Tx and Rx lines are crossed.
(iii) It means pin 1 & 2 of the plug on one end are connected with pin 3 & 6 of the plug on other end, and vice versa (3 & 6 to pin 1 & 2).
(iv) The easiest way to make a crossover cable is to make one end to T568A colour coding and the other end to T568B.
