That is: floating point unit: because the calculation of the floating point unit requires a lot of processing power, it is difficult for the processor to perform mathematical operations in the case of floating point (that is, the point containing the decimal point), and the floating point unit appears to perform and execute these Operation. Integer unit: This is the unit responsible for performing mathematical operations involving integers. It is the most important unit in most programs. Recorder: The structure of the recorder varies from computer to computer, as it includes a set of general-purpose registries and other loggers with special-purpose registries; the difference between public and private-purpose registries is that public registries can be used for purpose without having to limit them to a specific purpose, while the private registry insists on a specific job, not others.

The control unit ControlUnite (represented by the acronym CU) and this core component of the CPU are responsible for calling the instructions that are input into the computer and stored in the main memory, then sequentially decode their implementation, and finally carry the results and transfer them to the main The memory is processed in the computer in the CPU recorder.

The difference between RAM and read-only memory The main difference between RAM and read-only memory is the purpose of use, because the operating system uses RAM to perform various computer operations, such as storing programs in addition to storing different information during implementation, The read-only memory is mainly used to operate the computer, it is a read-only memory. It contains commands needed by the BIOS to start the computer. Another difference between the two types of memory is the write speed on this memory, the write process on random memory is faster, and the process of rewriting read-only memory (if programmable) is slower. Capacity is also an important difference between these two types. RAM capacity is much larger than read-only memory, the latter can only store a few megabytes, while the former is only a few gigabytes.
