U, also it limits the amount of CPU time each operation may take /tells them what it wants to do. There is an instruction decoder that reads the pattern of information in a specific register and decodes the pattern into an operation.The term Control Bus is when data travels between the CPU and memory on parallel wires called a "bus." One line contains the control signals that are generated from within the CPU. Another line senses the input signals. Every bus operation begins with a new clock tick. The term Address Bus is what is used to locates information in memory addresses, its a one way line from the processor, Each memory location has an individual address, the CPU accesses a particular address by putting the specific address in binary format on to the address bus. The term Data Bus is what is used to transfer data between the CPU and memory by a two way transfer that can read information or write new information into memory when the correct memory location is found, but its only able to write the new information to RAM memory.MEMORYCPU1- MEMORY ADDRESS (ADDRESS BUS)2 - CONTROL SIGNAL (CONTROL BUS)3- DATA (DATA BUS)1-Knocking on door to open it.2-Transfer the data.3-Telling it what it wants to do. 4. The diagram on the last page shows how CPU registers are used, the diagram is called the Fetch / Execute Cycle, and there is two main parts, the fetch cycle and the execute cycle. These cycles can be divided into a more specific description of how the registers are used, the fetch part of the cycle is the same regardless of the instruction but the instructions will change in the execute part of the cycle.This cycle can be broken down into a more detailed account of how the various registers are used they are detailed below.Registers, are specialized storage areas, these are used to hold information temporarily while it is being decoded. Each of these registers has a defined purpose to carry out so that the computer can operate effect...
