It is employed to hold temporarily the right hand instruction from a word in memory..
For example, The IAS machine's basic unit of information was a 40-bit, so that two instructions could be stored in each 40-bit memory location. Each instruction consisted of an 8-bit {operation code} and a 12-bit address.
Hence the IBR (Instruction Buffer Register) is used to temporarily hold Right hand instruction for the next use.

Instruction Buffer Register?
An Instruction Buffer Register is also known as IBR. It registers a computer's processor or its Central Processing Unit (CPU).

How does the Fetch Decode Execute work?
The program counter in the processor holds the address of the next instruction needed from main memory. The program counter copies its contents into the memory address register. The memory address register then sends the address along the address bus to main memory and the contents of the memory location specified by the address are sent along the data bus to the memory buffer register. The contents of the memory buffer register are then copied to the current instruction register where they are decoded and executed.

Which register modifies ret instruction?
instruction register
What register points to the next instruction?
actually register holds the data..there are 6 register which are temporary registers..program counter holds the address of next instruction to be fetched..instruction register holds the currently executed data...

What is the consists in the Instruction register?
The Instruction Register contains the current instruction being executed. It is an internal, special register, and you can not do anything explicit with it. If you are referring to the Program Counter, that simply contains the address of the next instruction to execute. It is incremented for each opcode and operand byte fetched.
