The microprocessor contains the CPU of a microcomputer. It is composed of the Arithmetic Logic Unit, Cache Memory (optional), Memory Management Unit (optional), Bus Interface Unit, Control Unit, Instruction Decoder, and Registers.
In the 8086/8088, the execution unit is the part of the processor known as the CPU. It executes the instructions and generates the results. The bus interface unit, on the other hand, is the part of the processor that handles reading and writing to memory. The two are somewhat loosely coupled, with the bus interface unit attempting to always be ahead of the execution unit, i.e. using the cache, so that the execution unit's wait time is minimized and performance is maximized.

The Bus Interface Unit (BIU)
If you mean after external hard drives, probably am 80 GB credit card. MSM9841 and MSM9842 offers two types of memory interface: interface when DMA controller is used (16-bit bus) that memory interface is through DMA controller; interface without DMA controller that memory interface (16-bit bus) is through CPU.
How Memory interface with CPU indicate the direction of signal and control signals?
The bus interface unit is the part of the processor that interfaces with the rest of the PC. Its name comes from the fact that it deals with moving information over the processor data bus, the primary conduit for the transfer of information to and from the CPU. The bus interface unit is responsible for responding to all signals that go to the processor, and generating all signals that go from the processor to other parts of the system.
The execution unit execute the instruction while the bus interface unit do the fetching and shows the results as an output
The largest unit of memory is a Yoda Byte. :)
Power interface Unit.
RAM is generally measured in Megabytes or Gigabytes
