Differences Between Wireless Network And Wired Network?

1.	Differences Between Wireless Network And Wired Network?
Answer» Wired network uses wires (e.g., twisted pair, coax, fiber optic) as transmission media in physical layer. Wireless network uses air waves, which requires different coding, modulation schemes. Interference and collision is much more severe in wireless networks. Data link layer in wireless network uses different techniques to AVOID collision and make sure data was received. Wireless network needs to DEAL with device location and handover in network layer. In wireless ad hoc networks, ROUTING can be different than wired networks. No BIG difference between wireless and wired network in transport layer. Application layer is unaware of the physical aspects of the network. Application layer in wired network supports services like FTP, SMTP etc. One can also take the physical layer characteristics into account when writing an application. One can also take the physical layer characteristics into account when writing an application.
