confusion - computer networks
Do we actually need ip and Mac addresses both at same time for the computer for communication? Why we not use Mac instead of ip address since Mac is also the unique address globally? Why we not use ip instead of Mac Since both are unique but why we use both for computer networkws?

Forouzan's Sliding Window Numerical
I was scrolling through sample questions when I chanced over this question. Consider a sliding window flow control protocol between hosts A and B. Suppose the link propagation delay is 1 time unit, the retransmission timeout is 3 time units ... I would really appreciate any help regarding this question. Also, can someone please leave a link to similar questions?

Finding optimal window size
Finding Optimal Window Size In Slinding Window Protocol. Given Round trip time(RTT sec), Bandwidth(BW bits/sec), packet size(L bits), which approch is right? Approch 1. max data that can be sent in RTT = RTT * BW bits max window size = (RTT * BW)/L ... = (1 + 2a) packets; a=Tp/Tt Some problems are sloved with approch 1 and others with 2nd one. Which one should we use?

Made easy question about sliding window protocol
Options are: 8,4,6,7. This is a multiple correct question. Answer as per key is 8,6,7 Their explanation is this: My doubt: if the window size is 8, then why does the sender wait for acknowledgement after sending 3 packets? It can send more without waiting.
