A common multipoint link is being used by four stations. Station $1$ is to the furthest left andStation $4$ is to the furthest right, with the remaining stations in between.a$.$ Station $1$ attempts to send a frame to Station $4$ at time t $=10$ msb$.$ The first bit of the frame reaches Stations $2,3$ and $4$ at times t $=11\mathrm{.}7$ ms$,17$ ms and $19$ms respectivelyc. Station $1$ sends the last bit of the frame at time t $=27\mathrm{.}3$ msDraw a space and time model of the channel if it is using CSMA$/$CD$.$What is the Transmission Time and Maximum Propagation Time from the given information?What should be the Minimum Frame Size and does it meet the requirements given above if thebandwidth is $7$ Gbps$?$
