WHAT IS STRAIGHT-THROUGH NETWORK CABLE?

  • Usually use straight cable to connect different type of devices.
  • If you need to check how straight cable looks like, it's easy. Both sides (side A and side B) of cable have wire arrangement with same color.

Pin3------------------------------------- Pin3
Pin4------------------------------------- Pin4
Pin5------------------------------------- Pin5
Pin6------------------------------------- Pin6
Pin7------------------------------------- Pin7

This type of cable will be used most of the time and can be used to:
  1. Connect a computer to a switch/hub's normal port.
  2. Connect a computer to a cable/DSL modem's LAN port.
  3. Connect a router's WAN port to a cable/DSL modem's LAN port.
  4. Connect a router's LAN port to a switch/hub's uplink port. (Normally used for expanding network)
  5. Connect two switches/hubs with one of the switch/hub using an uplink port and the other one using normal port.


What is Cross-over Network Cable?

  • A crossover cable is a cable that is used to interconnect two computers by "crossing over" (reversing) their respective pin contacts.
  • Sometimes you will use crossover cable, it's usually used to connect same type of devices.
  • The reversing or swapping of cables varies, depending on the different network environments and devices in use. 
  • Examples of crossover cables are null modem cables, rollover cables and loopbacks.

A crossover cable can be used to:

  1. Connect two computers directly.
  2. Connect a router's LAN port to a switch/hub's normal port. (Normally used for expanding network)
  3. Connect two switches/hubs by using normal port in both switches/hubs.



In cross cable connectivity is like as follows:
