Q24: Which of the following option is FALSE? (a) Control is a basic function that a computer can perform, in which control unit manages the computer's resources and orchestrates the performance of its functional parts in response to instructions (b) Program execution consists of repeating the process of instruction fetch and instruction execution. (c) Interrupts do not improve processing efficiency (d) Timing refers to the way in which events are coordinated on the bus. Q25: Which of the following option is TRUE? (a) An I/O module cannot exchange data directly with the processor (b) A key characteristic of a bus is that it is not a shared transmission medium. (c) Computer sy at various levels of the computer system hierarchy. (d) In general, the more devices attached to the bus, the greater the bus length and hence the greater the propagation delay. V/O module cannot exchange data directly with the processor stems contain a number of different buses that provide pathways between components

Explanation / Answer

Q24.
