The hardware$/$user gap refers to $\_\_\_\_\_.$

a$.$ the mismatch between the needs of different users

b$.$ the ability of users to utilize the system efficiently

c$.$ the mismatch between hardware capabilities and user needs

d$.$ the capabilities of the operating system and other system software

A computer system is running several applications. The system$$s ability to create the illusion of simultaneous execution of the applications is known as $\_\_\_\_\_\_\_\_\_\_\_\_.$

Which technique improves system resource utilization by holding active programs in memory while the programs wait for I$/$O completion or for an event to take place?

$\_\_\_\_\_\_\_\_\_\_\_\_$

A process in the $\_\_\_\_\_$ state has the necessary resources and control of the CPU.

Transferring control of the CPU from one process to another is called a$/$an $\_\_\_\_\_.$

Using threads rather than multiple processes avoids the need for $\_\_\_\_\_\_?$

A process control block replicates its information to each thread control block. What data is replicated?

Which algorithm needs to implement an arbitration rule?

a$.$ Shortest Job First $($SJF$)$

b$.$ Shortest Remaining Time $($SRT$)$

c$.$ First$-$In$-$First$-$Out $($FIFO$)$

d$.$ All of the above
