What is the difference between Straight cable and Cross cable?

Answer 1

It's the difference in how a cable is wired. It's called the Pin-Out.

Ehternet uses 2 pairs of wires in a cable. 1 pair for Send the other for Recieve. On a standard RJ45 Jack, pins 1 and 2 are the Send Pair and pins 3 and 6 are the recieve...... a straight through cable is wired identically at both ends. a crossover cable switches the pairs 1 and 2 and 3 and 6...... the the wire connected to pin number 1 is connected to pin number 3 at the opposite end of the cable and the wire for pin 2 is connected to pin 6 at the other end..... it just crosses over the pairs.

A note about Sam's Answer. Hubs are now obsolete and all modern switches don't require crossover cables anymore because modern equiment has auto-sensing MDI/MDIX Ethernet ports.

The most basic answer is that a crossover switches the send and receive of any cable. Not just ethernet. A crossover cable it also referred to as a loopback cable. It can be used to test equipment by making a single port communicate with itself because the port on the other end of the cable is simply relaying the data directly back to the originating port (Unless it is a newer eithernet port with an Auto MDI/MDIX port... then the test doesn't work).

Answer 2

Think one pair of leads in the usual Ethernet cable be shaped === in a straight, but with a cross cable it is shaped =x=. The former straight type is for wiring a complete network with all kinds of network devices and multiple computers in one network.

But cross type cable is down-and-dirty method of wiring a simple 2 and only 2 machines network. The ends of a cross cable plugs directly to the 2 machines. There is no expandability beyond two machines. Although the software setup is identical in both types.

Answer 3

Define Crossover Cable

Answer 4

There is absolutely no difference, as long as the cable is wired correctly. Switches can, in general, cope with straight-through or cross-over cables and even cables that have TX+ and TX- swapped (or RX+ & RX-). Network cables contain 4 twisted pairs of wires and each pair has a different number of twists per meter. This is fairly important. What is absolutely essential, however, is that the pairs are treated as such. This means that TX+/TX- *MUST* be a pair (so must RX+/RX- ). If you have so-called "split pairs" the cable may test 100% for continuity but completely fail in use.

Answer 5

The connection between two points of the cable is different . That s the reason why they say cross or straight . But I do not know how to connect them properly.

Answer 6

You mean for network cables?
A cross-over network cable is for connecting 2 (and only two) computers with network adapters. This forms a simple network with no additional parts needed.

A regular network cable is used to connect a computer network adapter to a router or some other network device. Some routers can use both straight and cross-over network cables when you want to connect the computer to the router.

Answer 7

I think you may be refering to serial cables. A straight cable is the norm for computer to periperal communication. A "cross over" cable will swap the send and receive signals usually used in networking two computers.

Answer 9

Straight cable used for connecting defferent devices..

Like PC to switch
Switch to Router
PC to Hub

Cross cable used for connecting same devices..

PC to PC
Switch to Switch

Answer 10

straight cable only likes other cables of an opposite sex and cross cable goes both ways
