Q. Define Various classes of Interrupts?
Figure below gives list of some common interrupts and events which causes occurrence of those interrupts.
Figure: Various classes of Interrupts
Interrupts are a useful mechanism. They are helpful in improving the efficiency of processing. How? This is to fact that almost all external devices are slower than processor so in a typical system a processor has to continually test whether an input value has arrived or a printout has been finished in turn wasting lots of CPU time. With the interrupt facility CPU is freed from task of examining status of I/O devices and can do useful processing during this time so raising the processing efficiency.

Q. Illustrate Diffrent types of modems? There are four different types of modems: half-duplex, full-duplex, synchronous, and asynchronous.With half-duplex modems data can be tr
Q. Explain Addressing modes in RISC? Simple addressing modes: Another benefit is the use of simple addressing modes. RISC machines employ simple register addressing having disp
Define speculative execution. Speculative execution means that instructions are implemented before the processor is particular that they are in the correct execution sequence.
