Q. Illustrate basic working of Physical layer?
Physical layer: Physical layer is concerned with sending raw bits between source and destination nodes over a physical medium. Source and destination nodes have to agree on a number of factors.
Signal encoding: how are the bits 0 and 1 to be represented?
Medium: what is the medium used and its properties?
Bit synchronization: is the transmission asynchronous or synchronous?
Transmission type: whether the transmission is parallel or serial?
Transmission mode: is the transmission simplex, half-duplex or full duplex?
Topology: what is the network topology i.e. mesh, star, bus or ring?
