Answer / harshkaushik

wireless communication is simply a medium to communicate
from one device to other without having a physical link in
between them
wired communication is the medium of communication in which
we use guiding structure like coax , optical fiber or
twisted paired cable as a medium of transmission
co channel cells may be defined as the cells that are having
same frequency the interference resulting in between the
signal from co channel cells is co channel interference
while adjacent cells are those cells that are having less
separation frequency from the desired channel the
interference in between the signal from adjacent cells is
adjacent channel interfernce

Answer / bindhu

any 2 devices connected with physical media like copper ,
coaxial wires is wired n/w and a n/w in which comm'n is
carried out via air as medium is wireless n/w.

Answer / e.naresh

co-channel interferance is""caused in a channel due to the crosstalk from two different transmitters which are uses the same frequencies""
adjacent channel interferance is""caused in a channel due to extra power releases/dissipates from a signal in adjacent channel""

The server is already having the list of IP addresses of all its authorized clients & if any client is requesting the server to do a task, it is sending its IP address(encapsulated in the packet) to the server.The server can easily match that IP address with that on its list and check if it's authorized client or not, then why we need inverse domain...........
