 this creates entries into the symbol table first and then creates the object code.

 the return address from the subroutine is pointed to by the pc.

 the registers store the return address of the routine and is pointed to by the pc.

 in dma the i/o devices are directly allowed to interact with the memory without the intervention of the processor and the transfers take place in the form of blocks increasing the speed of operation.

 the processor upon receiving the interrupt should let the device know that its request is received.

 the delay in servicing of an interrupt happens due to the time is taken for contact switch to take place.

 none.

 this resistor is used to pull up the voltage of the interrupt service line.

 the maskable interrupts are usually low priority interrupts which can be ignored if a higher priority process is being executed.

 the trap is a non- maskable interrupt as it deals with the ongoing process in the processor. the trap is initiated by the process being executed due to lack of data required
