Question

Wireless Networking What is NRZ-L? What is a major disadvantage of this data encoding approach?

Answer 1

In NRZ-L, double 1 is represented by helpful voltage and 0 by negative voltage. This scheme, though simple, creates problems: if there is a organization problem, it is difficult for the phone to orchestrate, and many bits are lost. In NRZ-L, 1 is represented by positive voltage and 0 by pessimistic voltage. organization is a problem in this encoding scheme. NRZ-L is used for short distance linking workstation and modem or terminal and computer. DISADVATAGES Coarsening of data Coding of value judgements Coding can obscure the denotation of the data People can get confused and may not be able to read or recognize it ex leaving your site.
