ASSALAM O ALAIKUM,.....

MY PPR WAS DONE OK BY THE GRACE OF ALLAH ALMIGHTY.

mcqs 70% from moazz file rather some are new 2 are from  latency and throughput.

How many types of exceptions can occur in a machine? Explain any two of them. 5marks

types of exceptions

·         Program Exceptions

·         Hardware Exceptions

·         Trace and debugging Exceptions

·         Nonmaskable Exceptions

·         Interrupts (External Exceptions)

Program Exceptions
These are exceptions raised during the process of decoding and executing the
instruction. Examples are illegal instruction, raised in response to executing an
instruction which does not belong to the instruction set. Another example would
be the privileged instruction exception.
• Hardware Exceptions
There are various kinds of hardware exceptions. An example would be of a timer
which raises an exception when it has counted down to zero.
