What is the functional unit that can directly exchange information with the CPU?

The functional unit that can directly exchange information with the CPU is: internal memory (main memory). Internal memory is a storage space that can be directly addressed by the CPU and can directly exchange information with the CPU. As long as the computer starts running, the operating system will transfer the data that needs to be calculated from the memory to the CPU for calculation. When the calculation is completed, the CPU will transmit the results.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

The functional unit that can directly exchange information with the CPU is: internal memory , also known as internal memory and main memory, is one of the important components of the computer.

Internal memory is used to temporarily store operation data in the CPU and exchange data with external memories such as hard disks. It is the bridge between external memory and the CPU. All programs in the computer run in the memory. The performance of the memory affects the overall performance of the computer.

As long as the computer starts running, the operating system will transfer the data that needs to be calculated from the memory to the CPU for calculation. When the calculation is completed, the CPU will transmit the results.

Internal memory is a storage space that the CPU can directly address and is made of semiconductor devices. It is characterized by fast access speed.

Memory is the main component in the computer, which is relative to external memory.

The programs we usually use, such as: Windows operating system, typing software, game software, etc. They are generally installed on external storage such as hard disks, but their functions cannot be used only because they must be transferred into memory to run in order to truly use their functions.

When we usually enter a piece of text or play a game, we actually do it in memory. Just like in a study room, the bookshelves and bookcases where books are stored are equivalent to the external storage of the computer, and the desk where we work is equivalent to the memory.

Usually, we store large amounts of data that need to be saved permanently on external memory, and put some temporary or small amounts of data and programs on memory. Of course, the quality of the memory will directly affect the running speed of the computer.

Memory is a place where programs and data are temporarily stored. When we use WPS to process a document, when you type characters on the keyboard, it is stored in memory. When you choose to save, the data in the memory will be saved to the hard (disk) disk.
