1. What is Address Binding?
a) going to an address in memory
b) locating an address with the help of another address
c) binding two addresses together to form a new address in a different memory space
d) a mapping from one address space to another
Explanation: Address Binding is a mapping from one address space to another
2. Binding of instructions and data to memory addresses can be done at ___________

b) Load time
c) Execution time
d) all of the mentioned
Explanation: all of the mentioned
3. If the process can be moved during its execution from one memory segment to another, then binding must be _________
a) delayed until run time
b) preponed to compile time
c) preponed to load time
d) none of the mentioned
Explanation: If the process can be moved during its execution from one memory segment to another, then binding must be delayed until run time
4. What is Dynamic loading?

8. The ___________ swaps processes in and out of the memory.
a) Memory manager
b) CPU
c) CPU manager
d) User
Explanation: The memory manager swaps processes in and out of the memory.
9. If a higher priority process arrives and wants service, the memory manager can swap out the lower priority process to execute the higher priority process. When the higher priority process finishes, the lower priority process is swapped back in and continues execution. This variant of swapping is sometimes called?
a) priority swapping
b) pull out, push in
c) roll out, roll in
d) none of the mentioned
Explanation: roll out, roll in
10. In a system that does not support swapping ____________
a) the compiler normally binds symbolic addresses (variables) to relocatable addresses
b) the compiler normally binds symbolic addresses to physical addresses
c) the loader binds relocatable addresses to physical addresses
d) binding of symbolic addresses to physical addresses normally takes place during execution
Explanation: In a system that does not support swapping the compiler normally binds symbolic addresses (variables) to relocatable addresses
