- In the context of memory management, describe in fully the differences between dynamic loading and static loading.Which of the studied data structures in this course would be the most appropriate choice for the following task? And Why? Input/output buffer is an area of a computer memory used to temporarily store data and instructions transferred into and out of a computer, permitting several such transfers to take place simultaneously with processing of data. Instructions are processed according to the arrival time and they are executed one by one.Please describe the shmat system function, including what a shared memory file is, how a process is generated, and why such a call is necessary.
