Do I need to use a crossover cable?
Crossover cables are needed only when connecting two Ethernet client devices, neither of which is configured for Gigabit Ethernet. Modern Ethernet devices automatically detect the use of crossover cables and work with them seamlessly.
Do you need a crossover cable between switches?
Technically speaking, cross over cables are supposed to be used when connecting devices of the same “type” together. Like connecting 2 PCs together, or 2 switches together. When connecting devices of different types together you use a straight through cable. Like when plugging a PC into a switch.
Do modern laptops need crossover cables?
Most (all?) current devices have implemented ethernet auto mdix. The answer is simple: You don’t need such cable.
Why it is necessary to crossover the cables to connect two PCS?
Crossover cables flip the transmit and receive wire pairs from one end to the next, so that the transmissions channel on one end corresponds to the receiving channel on the other and vice versa. This eliminates the need for a hub, switch or other intermediary hardware.
Do I need a crossover cable to connect two routers?
The rule of thumb is: when connecting similar devices (router to router, computer to computer) use a crossover cable. When connecting dissimilar devices (router to switch, computer to switch) use a straight through cable.
Why it is necessary to crossover the cables to connect two PCs?
Why a crossover cable is needed to connect two PCs?
Connecting two computers using a crossover ethernet cable is the safest and easiest way of transferring files, pictures, videos, and music. This data transfer creates a network for sharing data, and using two electronic resources, thus avoiding having a separate networking facility for each computer.
What are the disadvantages of crossover cable?
A disadvantage of using an Ethernet crossover cable is that the two machines are joined by a physical cable so they must be in fairly close proximity. Another potential disadvantage is that there is no optional built-in security as one has in a network.
When would you use a crossover cable over straight through cable?
When you connect two devices of different types together, you use a straight through cable. When you connect two devices of the same type together, you use a crossover cable.
