Interrupt vector table is always created in first 1K area of the memory. Explain why?
When CPU receives an interrupt type number from PIC, it uses this number to look up corresponding interrupt vector in memory. There are 256 interrupt types. Every interrupt vector occupies 4 bytes. Hence, a total of 4 x 256 = 1K bytes of memory is reserved at the beginning of processor memory address space for storing interrupt vectors.
Explain non-pre-emptive algorithms? Non preemptive algorithms: In this algorithm a job is provided to CPU for execution as long as the job is non-completed the CPU cannot
Why can CRC detect more errors than simple Checksum? There are two purposes a CRC can identify more errors than a simple Checksum. 1. Since an input bit is shifted by all th
What is Error detection code? It is a binary code that notice digital errors during transmission. The detected errors cannot be correct but the presence is shown.
