7. Which of the following is the area of memory that is used for temporary storage?
a) Register
b) Accumulator
c) Stack
d) Hard Disk
Explanation: Stack can be used at the time of function call or it is a short time large-scale storage of data. Therefore, a stack is an area within memory for storage.
8. PUSH-POP mechanism is seen in _______
a) Stack pointer
b) Register
c) Memory
d) Index register
