Computer Memory and Storage

Yes, root directory is called as main folder on a storage device.

Instruction set architecture determines the minimum number of page frames that must be allocated to a running process.

It indicates the address of the next instruction to be executed for this process.

It is the process of assigning load addresses to the various parts o the program, adjusting the code and data in the program to reflect the assigned addresses.

Here, a program can allocate or deallocate memory at arbitrary points during its execution.

This register makes data operations much more size efficient, with a single byte STOS instruction to write data out of the accumulator.

Yes, buses will carry the information from one component to the other component.

Yes, volatile is called as the information lost when the power is off .

Yes, it is correct.  It belongs to tertiary storage.

Yes,  secondary storage is called as auxiliary storage.  It is also called as mass storage device.

Micro program executes the OPCODE. These programmes are available in ROS of the processor.

Micro programs are written to produce relevant digital signals of the given OPCODE. Hence, option (2) is correct.

Overlay concept uses the free blocks of the main memory during run time to execute some portion of a program. So, when a larger size program is required to be executed, it is first fragmented in smaller continuous programmes, and those programmes are loaded and removed in/from memory as and when required.

Cache memory is used when pipelining is implemented in the processor architecture. 80486 architecture supports the pipelining. 

ECL can be easily implemented to have high speed memory chip. Because of its speed, it is favourable for implementing cache memory.
