What does a microprogram is sequencer perform the operation?
In computer architecture and engineering, a sequencer or microsequencer generates the addresses used to step through the microprogram of a control store. It is used as a part of the control unit of a CPU or as a stand-alone generator for address ranges.
Which operations are performed by Microprograms?
microprogramming
- microprogram store.
- control memory.
- control unit.
- writeable control store.
- program control.
- memory protection.
- control design.
- one-level store.
When CPU detects an interrupt what it do with current state?
Answer: CPU detects an interrupt, what it does with current state just save it to avoid losing the data without meeting any trouble of it. Additional it works well and keeps the systems away from the common problem without any risk. The CPU has control all process and analysis the major things and execute the output.
What is the unit which decodes and translates each instruction and generates the necessary enable signals for ALU and other units called?
Answer is “Control Unit”
Why do we need secondary storage?
Secondary storage is needed to keep programs and data long term. Secondary storage is non-volatile , long-term storage. Without secondary storage all programs and data would be lost the moment the computer is switched off. magnetic storage devices, such as hard disk drives.

What is microprogram control?
1) A control unit with its binary control values stored as words in memory is called as microprogrammed control. Each word in the control memory contains microinstruction that specifies one or more microperations for the system. A sequence of microinstructions constitutes a micro program.
What is computer microprogram?
[¦mī·krō′prō·grəm] (computer science) A computer program that consists only of basic elemental commands which directly control the operation of each functional element in a microprocessor.
What happens when a process requests for DMA transfer?
When the process requests for a DMA transfer? Explanation: The process requesting the transfer is paused and the operation is performed, meanwhile another process is run on the processor.
What is the unit which decodes and translates each instruction?
The unit which decodes and translates each instruction and generates the necessary enable signals for ALU and other units is called A. ALU.
What is an important data transfer technique?
Answer: (b) DMA. DMA stands for Direct Memory Access. In the DMA data transfer scheme, data is directly transferred from an I/O device to RAM or from RAM to an I/O device.
