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.
