Interrupts and Bus types

While CPU is executing a program, an interrupt exists then it

• follows the next instruction in the program

• jumps to instruction in other registers

• breaks the normal sequence of execution of instructions

• stops executing the program

An interrupt breaks the execution of instructions and diverts its execution to

• Interrupt service routine

• Counter word register

• Execution unit

• control unit

Identify the type of interrupt in which low priority interrupts are interrupted by high priority interrupts.

• Sequential interrupt

• Nested Interrupt

• Level triggered interrupt

• Edge triggered interrupt

Computer buses with 64 lines can carry

• 32 bits

• 64 bits

• 8 bits

• 16 bits

The maximum memory capacity of the system is determined by which type of bus

• Data bus

• Address bus

• Control bus

• Optical fiber bus
