Understanding CPU
CPU which stands for Central Processing Unit is a hardware component or the main data processing hardware device in a computer. The CPU can be called the brain of the computer because the CPU regulates all activities and runs all programs including applications or software in it.
Whatever it is, all things related to processes in the computer, even a trivial process will always be regulated by the CPU. For example, when you press the letter "H" on the keyboard while typing, the letter "H" will appear on the screen, the CPU is what makes this possible. Thus, without the CPU in the computer, the computer will not be able to do anything or the computer cannot run the program.
The CPU is technically also more often referred to as a processor, therefore when reading and recognizing the specifications of a processor, you are actually reading the CPU specifications of a device.
CPU Components
A CPU has at least a "processor" or a chip embedded in it that functions in the computer's calculation process. However, rapid technological developments also allow a CPU to have more than a processor or what is also known as a "processor core".
The terms that we often hear today also come from the development of CPU technology, for example "dual core" technology where in a CPU there are two processing cores, or quad cores which have four processing cores. A sophisticated CPU even has technology with six (hexa core) and eight processing cores (octo core).
CPU Function
The main function of the CPU is to perform arithmetic and logical operations on data retrieved from memory or from information provided by some hardware device. CPU is almost the same as a calculator, it's just that the CPU is much more complex in processing the instructions given. The instructions are then stored first in RAM, each instruction will be assigned a unique address called a memory address. Furthermore, the CPU can access the data in RAM by specifying the address of the selected data.
