Q. Explain working of Direct Memory Access?
In both programmed I/O and interrupt-driven processor is busy with executing input/output instructions and I/O transfer rate is limited by speed with which processor can test and service a device. What about a scheme that needs minimal intervention of CPU for input/output? These two types of shortcomings can be overcome with a more efficient technique called as DMA that behaves as if it has taken over control from processor. C Consequently the question is: why do we employ DMA interface? It is employed primarily when a large amount of data is to be transferred from I/O device to Memory.
What are the process states in Unix? As a process implements it changes state according to its circumstances. Unix processes have the following states: Running : The process
This boils down to the concept of Binary digits. Take an array size of 64 for example. We begin from 0 and end at 63. We need 6 bits.But, if we were to begin from 1 and end at 64,
