As we know parallel transmission is faster then serial then why serial is replacing parallel?

There is a greater risk of errors with parallel transmission because especially over longer distances, the bits may arrive at the destination at different times and therefore corrupting the data. Because serial transmission sends each bit one at a time, they always are received in order.

Speed of transmission is not always the driving priority, if the information cannot be reliably transferred to the destination all the speed in the universe is useless.

Does the distance between the two computers matter How does it affect the network?

The distance between two operating computers have no effect on each other. Unlike many electronic devices, computers towers themselves do not emit enough electro magnetic interference to cause harm to anything surrounding it. CRT monitors, however, can affect each other. When turning on a CRT that is closely positioned to another monitor, the second one will shake and flicker until the first one is fully on. This is only temporary because of its EMI. LCD monitors do not have this affect, nor are affected.

Concerning the network - there are no affects of cross talk between two computers that may harm information on the network lines.
