1. A computer system can be perceived from two profound perspective, its architecture and organisation. This two components are coordinated in a manner to achieve an optimal performance. In your opinion which of the above component of the computer system is more important. Justify your stance by enumerating at least three verifiable reasons to support your claim. 2. As part of the specification of a Pentium IV computer system, the bus moves data within the system with a speed of 400MHz. Determine the performance of the computer system's bus in terms of its clock cycle time. 3. A computer system has three peripherals connected to it via serial port, parallel port and universal serial port respectively. To what extent do these ports differ from each other and evaluate the performance of the computer peripherals with respect to its data transfer rate. 4. A potential candidate in an interview session, you have be called upon to explain how the electronic communication pathway within a computer system could be configured. Explain those configuration types, illustrate them and enumerate the merit and demerits of the configurations. 5. In which of the memory mapping techniques is a replacement policy not required? Explain why a replacement policy is not required in such memory mapping techniques. Q1a. Consider a microprocessor that has an on-chip 64 Kbytes cache, 16 MB main memory and data are transferred between main memory and cache in blocks of 4 Bytes each. Show the field information for direct, associative and two-way set associative mapping for memory address (19CF08)H [5 Marks] Q1b. Calculate the cycle time of a computer memory system if access time is 10 nanoseconds and delay time is 2% of the access time. Also calculate the data transfer rate. What happens to the access time if data transfer rate is doubled keeping other values same? [3 Marks]
