Explanation:
Detailed explanation-1: -The Central Processing Unit (CPU) is called “the brain of computer” as it controls operation of all parts of computer. It consists of two components: Arithmetic Logic Unit (ALU), and Control Unit.
Detailed explanation-2: -This mode of transfer of data technique is known as Direct Memory Access (DMA). During Direct Memory Access, the CPU is idle and has no control over the memory buses. The DMA controller takes over the buses and directly manages data transfer between the memory unit and I/O devices.
