Part 1
#1. What is the difference between interactive processing and real-time processing?
#2. Suppose a time-sharing operating system allocated time slices of 20 milliseconds and the machine executed an average of 5000 instructions per microsecond. How many instructions could be executed in a single time slice?
#3. A process is said to be I/O-bound if it requires a lot of I/O operations, whereas a process that consists of mostly computations within the CPU/memory system is said to be compute-bound. If both a compute-bound process and an I/O-bound process are waiting for a time slice, which should be given priority? Why?
Part 2
