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. 1. DMA is the best type of I/O technique for large transfers. 2. Each I/O device requires its own specific set of instructions or control signals for operation. 3. Monitor in OS is the central component of most computer OS, it is a bridge between applications and the actual data at the hardware level. 4. The DMA cannot transfer data between two I/O ports. 5. There exist four major theoretical advances in the development of OS 6. OSI reference model has six layers. 7. Internet Protocol is a connectionless protocol. 8. A scheduling is the key to multiprogramming. 9. Infrastructure mode is that each computer in network is sending packets to each other directly. 10. Computer systems can be divided into four components. 1. A computer system can be perceived from two profound perspective, its architecture and organisation.
