There are two type of register in computer cpu. first one is data register and second one is address register.
CPU register is faster than memory loacations
a special high-speed storage area in cpu.
A register variables is that which got space in CPU internal register sets this requst can be granted or rejected by CPU ,by register veriable the processing speed become much faster for that variable.

The word CPU is repeated in the question, and the category, 8086/8088, does not fit a category where there is a specific processor register. Please restate the question, and give more details, and/or the name of the register.
register is internal memory inside the cpu.
Simple answer - speed. By using the CPU register, the information is kept "local" to the CPU. By storing a value in a memory location, a lookup has to be performed to retrieve it.
The instruction register.
temporay data storage area of the cpu
it's instruction pointer register it's in cpu and it holds the instruction which the cpu fetching it from memory
Major difference between Bus and Register is that B for Bus while R for Register
