Computer Science Quiz

........ maps each block of main memory to only one possible cache line.

• Direct mapping

• Associative mapping

• Set associative mapping

• Indirect mapping

The cache is used to narrow the speed gap between ………. and ……….

• RAM and ROM

• RAM and HDD

• CPU and RAM

• None of the others

If an instruction which contains arithmetic operations, the data will be passed to:

• Control unit

• ALU

• I/O ports

• Registers

It's the operation updates the Program Counter (PC) to contain the address of some instruction in memory.

• Transfer of Control

• I/O

• System Control

• Skip Instruction

With memory-mapped I/O, which of the following statements is true?

• The I/O devices and the memory share the same address space

• The I/O devices have a seperate address space

• The memory and I/O devices have a seperate address space

• A part of the memory is specifically set aside for the I/O operation

Which types of transfers are supported by the connection structure of the computer?

• Memory to or from processor, I/O to or from processor, I/O to or from memory

• Memory to memory, memory to or from processor, I/O to or from processor

• I/O to or from processor, I/O to I/O, memory to or from processor

• None of the others

With isolated I/O, which of the following statements is true?

• The I/O devices and the memory share the same address space

• The I/O devices have a separate address space

• The memory and I/O devices have an associated address space

• A part of the memory is specifically set aside for the I/O operation

The data can be accessed from the disk using ……….

• Surface number

• Sector number

• Track number

• All of the others

Medium-term scheduling is:

• The decision as to which process's pending I/O request shall be handled by an available I/O device

• The decision as to which available process will be executed by the processor

• The decision to add to the number of processes that are partially or fully in main memory

• The decision to add which programs to the system for processes

A computer's memory is composed of 8K words of 32 bits each. How many total bytes in memory?

• 32,000

• 32,768

• 262,144

• 256,000
