$1.$ Estimate data transfer time using latency and Bandwidth.

$2.$ Calculate the Delay Bandwidth Product

$3.$ Name the $7-$layers of the OSI model and describe the protocol at each level and

compare it to Internet Protocol model and explain how it differs from the OSI model.

$4.$ Recognize different waveforms encoding $($NRZ$,$ NRZI, Manchester, and $4$B$/5$B

encoding$)$

$5.$ Processing a typical frame by identifying a frame header and body for the three types:

Byte$-$oriented, Bit$-$oriented and Clock$-$based protocols

$6.$ Apply different error detection techniques: parity check, checksum, CRC

$7.$ Implement the sliding window protocol

$8.$ implement multiple access protocols $($CSMA$-$CD: Ethernet and SCMA$-$CA: Wifi$)$

$9.$ Identify the tree different forwarding approaches:

a$.$ Datagram

b$.$ Virtual circuit

c$.$ Source routing

please just give examples of these with some sort of solution thanks I will upvote
