MCSE Interview Question:

Why we use cross cable to connect same devices?

Submitted by: Administrator

Same devices like PC-2-PC, it uses (NIC for PC) 1, 2 for transmission 3, 6 for reception. If we do not use cross cable then we cannot transfer data.While in the case of switch/hub they receive (NIC of SWITCH/HUB) data on 1, 2 transmit on 3, 6.That is why we use straight cable for de-similar host cross cable for similar hosts.
