Calculate the latency (from first bit sent to last bit received) for the following:
(a) 10-Mbps Ethernet with a single store-and-forward switch in the path, and a packet size of 5000 bits. Assume that each link introduces a propagation delay of 10 μs and that the switch begins retransmitting immediately after it has finished receiving the packet.
(b) Same as (a) but with three switches.
(c) Same as (a) but assume the switch implements "cut-through" switching: It is able to begin retransmitting the packet after the first 200 bits have been received.
1. Write a program to solve the selection problem. Let k = N/2. Draw a table showing the running time of your program for various values of N.

You are engaged by law firm to study evidence for the defence. You uncover evidence that doesn't help your client's case but was not discovered by the prosecution.
Do you agree or disagree that throughput and capacity are finding factors for effectiveness of system more so than processor speed?
Assuming the average packet size is 5 slot times, express the available bandwidth as a function of N.
Given two strings, A and B, create a bigger string made of the first char of A, the first char of B, the second char of A, the second char of B, and so on. Any leftover chars go at the end of the result
