Can you please explain me about instruction register?

Answer 1

Instruction register:-

it hold's the instruction decoded bu control unit..

if you know that bus is the communication Chanel of computer system,

whenever we enter some instruction it's going to pass by bus. but we send instruction in human understandable form so all data should be convert in bus understandable form. now all data convert in bus understandable form but here is the problem that what C.P.U. not able to understand that , so control unit convert all instruction in c.p.u. understandable form now all data converted in c.p.u. understandable form but still there in c.p.u. going some process so it can accept that thing right now ..so it can store in some where in c.p.u. that called instruction register..

I.R is the one type of register.it can hold very small amount of data.
