It was presumed long ago that switches or hubs would connect PC's and/or routers together, so this made simple straight-through wiring easy to use, but a problem occurs when you're directly connecting any PC to PC, router to router, or switch to switch because they're essentially talking into each other's mouths. By using a crossover cable, you fix this issue, though if you have a long setup that goes through multiple patch panels, you have to use only one crossover cable and the rest regular straight-through cables (or technically any odd number of crossover cables). Modern equipment can automatically flip the TX and RX pairs, and thus isn't an issue. This problem also exists on fiber with fiber polarity. Most SFPs transmit on one piece of glass and receive on another, so you have to make sure you don't have two transmitters pointing at each other or it won't work. There's no automatic solution for this (at least in widespread usage). There are also fiber SFP's that only use a single, simplex fiber cable as opposed to a duplex pair; in this case you have two different SFP's, one transmitting at 1310nm, the other at 1550nm, so in this case you have to make sure for every circuit you have one of each type.

I know this one! I'm going off of memory here so some values might be a bit off.

PCs, Routers, Switches, etc. All transfer data over copper pairs.

One of the wires in a pair transfers and the other receives on the port of the NIC card. PC NIC cards transfer on 1 and 3 pins and receive on 2 and 6 pins.

A sequel to the 2008 film Ip Man, the film was directed by Wilson Yip, and stars Donnie Yen, who reprises the leading role. Continuing after the events of the earlier film, the sequel centers on Ip's movements in Hong Kong, which is under British colonial rule. Ip man download free.

Switches on the other hand are the opposite (receive on 1 and 3 and transmit on 2 and 6). So when you connect a cable from a PC to a switch, the can use a straight through cable. However, if you want to connect two PCs or two switches together, you may need a crossover cable instead. Note: I say 'may need' because of something called 'auto MDI-X' which allows a switch, for example, to detect that the pins would need to switch roles. I wrote specifically about the 'why' behind crossovers here: The gist of it is. There are two types of NIC's: MDI and MDI-X.

The difference between the two is they each transmit on a different pair of wires. When connecting an MDI nic to an MDI-X nic, the transmit pair correlates to the opposite NIC's receive pair: 'End points' on a network typically use the MDI specification (Hosts, Routers).

'Intermediate' devices on a network typically use the MDI-X specification (Switches, hubs). This makes it so when an endpoint is cabled to an intermediate device, the wire pairs line up perfectly: BUT, when you have two 'like' devices, the wire must introduce a 'crossing of the pairs' so that what is transmitted by one speaker is received by the other: This also includes when two devices with MDI-X NIC's are connected to each other. Note the 'wire' between these two switches also has a crossing of the pairs: • • • • • •.
