CALCULATIONS 1 A file has a six million bytes How long will

CALCULATIONS:

1.    A file has a six million bytes. How long will it take to download this using a 2Mbps channel?
[chapter 2]

2.    Code the 4B sequence 1110 0111 into 5B, using 4B/5B mapping codes. [chapter 4]

Solution

6million bytes=6Mb

2Mb will take 1sec to download

for 6MB, t=6MB/2MB= 3Sec

its require 2 sec.

2.

Using 4B/5B mapping

1110 -11100

0111-01111

he encoded messsage 11100 01111
