Operating system swapping process
Please help me explaining this in simpler words: If we were to swap out process P1 and swap in process P2, the I/O operation might then attempt to use memory that now belongs to process P2. There are two main solutions to this ... system buffers and process memory then occur only when the process is swapped in. Note that this double buffering itself adds overhead.

Assume a 10Mbps Ethernet has two nodes, A and B, connected by a 360m cable with three repeaters in between, and they each have one frame of 1,024 bits to send to each other. Further assume that the signal propagation speed across the cable is 2*10^8 m/sec ... an 8bit processing delay in addition to a storeandforward delay. At what time, in seconds, is A's packet delivered at B
