Identify CORRECT function of control bus for a computer system.

[CLO1-C1]

• Connecting major component such as CPU, memory and I/O unit

• Moving data between system modules

• Indicating the source or destination of data on the data bus

• Regulating the access data and uses of data and address line

Identify the INCORRECT point which related with the comparison between CACHE MEMORY L3 and L1.

[CLO1-C1]

• L1 will offer higher speed than L3

• L3 will offer more storage capacity than L1

• L1 will offer less storage capacity than L3

• L3 will offer higher speed than L1

Identify the mode of transfer as described in the statement below :

 

                  It can transfer data directly to and from memory rather

                  than using the CPU as an intermediary, therefore can

                  relieve burden on CPU and congestion on the bus system

 

[CLO1-C2]

• Programmed I/O

• Memory mapped

• Interrupt-driven I/O

• Direct Memory Access (DMA)
