The address space provided for each and every user for 16MB is
- A.
23 bit
- B.
31 bit
- C.
24 bit
- D.
33 bit
Correct Answer
C. 24 bitExplanation
The address space provided for each and every user for 16MB is 24 bits. This means that each user is allocated a unique address range within the 16MB memory space. With 24 bits, it is possible to represent 2^24 different addresses, which is sufficient to cover the entire 16MB address space.Rate this question:

i/o Device address is –
- A.
8 bit long
- B.
16 bit long
- C.
32 bit long
- D.
64 bit long
Correct Answer
B. 16 bit longExplanation
The correct answer is 16 bit long. This means that the i/o device address is represented by a 16-bit binary number. The length of the address determines the range of addresses that can be assigned to different devices. With a 16-bit address, there can be a maximum of 2^16 or 65,536 unique addresses.

Which add to the difficulty of managing loosely coupled configuration?
- A.
Control Units
- B.
Resource Serialization
- C.
Communication Mechanism
- D.
Collection of Applications
Correct Answer
C. Communication MechanismExplanation
