Total Access Time Calculation
To calculate the total access time for the disk I/O transfer of 1500 bytes, we will consider three main components: seek time, rotational delay, and transfer time.

Understanding CSMA/CD Protocol
In a network using the CSMA/CD (Carrier Sense Multiple Access with Collision Detection) protocol, hosts A and B share the same communication medium. The collision detection mechanism is crucial for ensuring data integrity during transmission.

Host A is sending data to host B over a full duplex link. A and B are using the sliding window protocol for flow control. The sender and receiver window sizes are 5 packets each. Data packets (sent only from A to B) are all 1000 bytes long and the transmission time for such a packet is 50 μs.Acknowledgement packets (sent only from B to A) are very small and require negligible transmission time. The propagation delay over the link is 200 μs. Calculate the maximum achievable throughput.- a)15.00 x 106 bps
