Question

Write about swapping. Let us assume the user process is of size 1MB and the

backing store is a standard hard disk with a transfer rate of 5MBPS. Calculate the

transfer rate.​

Answer 1

Answer:

Suppose the user process's size is 2048KB and is a standard hard disk where swapping has a data transfer rate of 1Mbps. Now we will calculate how long it will take to transfer from main memory to secondary memory.

User process size is 2048Kb

Data transfer rate is 1Mbps = 1024 kbps

Time = process size / transfer rate

= 2048 / 1024

= 2 seconds

= 2000 milliseconds

Now taking swap-in and swap-out time, the process will take 4000 milliseconds.
