Question:
Why we use cross cable to connect same devices?
Answer:
Same devices like PC-2-PC, it uses(NIC for PC) 1,2 for transmission & 3,6 for reception. If we don't use cross cable then we can't transfer data.
While in the case of switch/hub they receive (NIC of SWITCH/HUB)data on 1,2 & transmit on 3,6.
Thats why we use straight cable for de-similar host & cross cable for similar hosts. Source: CoolInterview.com

Because cross cable has opposite function of wire. in utp cable has 8 wires but 4 wires only use in which first 1,2 wires has +data transmit and 3,6 wires has -DATA recieve. same device cant send data to same transmit wires pc to pc does not use same wire for +DATA and -DATA so use opposite..
