What does DMA stand for?

What does DMA stand for? Correct Answer direct memory access

The DMA is direct memory access which can modify the memory without the help of the processor. If any kind of memory access by DMA to be done, it will passes a request to the processor bus and the processor provides an acknowledgment and gives the control of the bus to the DMA.

On a non-pipelined sequential processor, a program segment, which is a part of the interrupt service routine, is given to transfer 500 bytes from an I/O device to memory.     Initialize the address register     Initialize the count to 500 LOOP: Load a byte from device     Store in memory at address given by address register     Increment the address register     Decrement the count     If count! = 0 go to LOOP Assume that each statement in this program is equivalent to a machine instruction which takes one clock cycle to execute if it is a non-load/store instruction. The load-store instructions take two clock cycles to execute. The designer of the system also has an alternate approach of using the DMA controller to implement the same transfer. The DMA controller requires 20 clock cycles for initialization and other overheads. Each DMA transfer cycle takes two clock cycles to transfer one byte of data from the device to the memory. What is the approximate speedup when the DMA controller based design is used in place of the interrupt driven program based input-output?
How many persons are standing there in a straight line, all of them facing the north? I. Only one person stands to the left of Z. Only three person stand between Z and A. The person who is immediate right of A stand at the extreme right end of the line. II. Only two persons stand to the left of Z. Only two person stand between Z and H. H stand to the immediate right of A. A stands exactly in the middle of the line.
Consider the following statements. I. Daisy chaining is used to assign priorities in attending interrupts. II. When a device raises a vectored interrupt, the CPU does polling to identify the source of interrupt. III. In polling, the CPU periodically checks the status bits to know if any device needs its attention. IV. During DMA, both the CPU and DMA controller can be bus masters at the same time. Which of the above statements is/are TRUE?
To indicate the I/O device that its request for the DMA transfer has been honored by the CPU, the DMA controller pulls
A student reaches the bus station at speed of 8 km/hr on the cycle, boards the bus to the B point whose speed is 15 km/hr. From B to the rickshaw stand he gets a lift from the bike which travels at speed of 20 km/hr. From the rickshaw stand to the exam center he travels at speed of 12 km/hr. If the distance between home to the bus station, bus station to B, B to rickshaw stand, Rickshaw stand to exam center is equal then find student’s average speed. (Approximate values whenever felt necessary)
