Identify the technique to free up the CPU by allowing device controllers to independently transfer data between the device and main memory.
a. Programmed I/O.
b. Direct Memory Access (DMA).
c. Polling.
d. CPU interrupt.

Answer:

B. - Direct Memory Access (DMA)

Explanation:

...

Direct Memory Access (DMA) is the technique to free up the CPU by allowing device controllers to independently transfer data between the device and main memory. Thus, option B is correct.

Direct memory access is a computer system feature that allows some hardware subsystems to access main system memory without relying on the central processor unit.

Direct memory access (DMA) is the method of transmitting data without using the CPU. It is frequently used to transport data to and from input/output devices. To manage the transfer, a second DMA controller is necessary.

DMA is a mechanism that allows an input/output (I/O) device to transmit or receive data directly to or from main memory, bypassing the CPU to speed up memory operations. A chip known as a DMA controller manages the process (DMAC).

Therefore, option B is correct.

Suppose you are asked to design a rotating disk where the number of bits per track is constant. You know that the number of bits per track is determined by the circumference of the innermost track, which you can assume is also the circumference of the hole. This, if you make the hole in the center of the disk larger, the number of bits per track increases, but the total number of tracks decreases. If you let r denote the radius of the platter, and x · r the radius of the hole, what value of x maximizes the capacity of the disk?
