Flow Control :The flow of control passes to the next sequential instruction in
memory unless directed otherwise by branch instructions, nullification of
instructions, or interruptions.
Branching
•Unconditional branch instructions
Always branch to the specified target•Conditional branch instructions
Perform some operation (move, compare, add, or bit test) and then branch if the
specified condition is met
•Delayed branch feature
The instruction following the branch is executed before control passes
to the branch destination.

classes of interruptions are handled in the same wayThe interruptions are
categorized into four groups based on their priorities
