Q. 1 Discuss the functional view of a computer system? How it is related with the structural view?

Q. 2 Do some research on Internet and explore the latest generation of computers? Write some important and distinct features of latest generation.

Q. 3 Explain basic instruction cycle. State your answer with the help of diagram.

Q. 4 Elaborate the concept of multiple bus hierarchies. Give brief description of bus types and their uses.

Q. 5 Give reason why RAMs traditionally have been organized as only one bit per chip whereas ROMs are usually organized with multiple bits per chip.

Note: All questions carry equal marks.

Q. 1 In virtually all systems that include DMA modules. DMA access to main memory is given higher priority than the processor access to main memory. Why?

Q. 2 Give reasons that page in a virtual memory system should be neither very small nor very large.

Q. 3 Using 1s and 2s complements perform the following subtractions.
a) 1000110 11011
b) 1101010 110100
c) 10011.1101 101.11
d) 1010 11011

Q. 4 Many instructional sets contain the instruction NOOP, meaning no operation, which has no effect on the state of CPU (like changing contents of any register or memory location) other than incrementing the program counter. Suggest some uses of this instruction.

Q. 5 Discuss the characteristics and functions of instructional sets. State your answer in the context of operator and operand types.
