Q1: What is computer organisation?

A1:  Computer system’s entire structure all together including Central Processing Unit, I/O Devices, memory makes up a computer organisation. Each and every part of the computer, it’s function, how the components operate and are connected to each other is explained under computer organisation.

Q2: What is Computer Architecture?

A2: It is an area under which interaction between hardware and software technologies to create a computer system is described. It involves building computers, it’s parts and necessary equipment for the computer to work. It consists of System design, Instruction set architecture and Micro architecture.

Q3: How to accelerate computer performance?

A3: Based on how quickly a computer can execute programs, determines the most important measure of the performance of a computer. Design of the computer executes affects the speed with which a computer executes program. It is necessary to design the compiles, the machine instruction set, and the hardware in a coordinated way, for it’s best performance,.

Q4: What is career look like in Computer Architecture?

A4: As long as computers exists in this world, there will be a demand for computer architects. Since everyone uses computer these days and it has become necessary to work on computers. there is a high necessity of computer architects. It is expected that there will be 6% growth for employment in computer architecture. A lot of people are preferring to work on line, computer architects will have an interesting career to work forward.

Q5: What are output unit and control unit?

A5: Output units are the counter[arts of input unit. Sending the processed results to the outside world is the basic function of output unit.

Where as control unit acts as nervous system of the computer. It sends signal to other units and senses their states. The signals that govern the data transfer between processor, input unit, output unit and memory are generated by the control unit.

Q6: What is the difference between Memory Address register (MAR) and Mmeory Data Register (MDR)?

A6: Memory Address register (MAR) – Address of the location to be accessed will be held by MAR

Mmeory Data Register (MDR) – Data to be written into or read out of the address location will be contained by the MDR
