Modern computers are powerful machines that allow you to both use the global information network and create various content: from documents to videos and others.

RAM and drive memory (storage), what's the difference?
Random access memory (RAM, RAM) - random access memory - part of the computer memory system that is used by the operating system, programs, as well as input, output and intermediate data processed by the processor.
Internal memory (drive, storage, hard drive, SSD, HDD) - computer memory that is used to store all data on the computer (including those that are not being used at the moment).
For a simpler understanding, let's compare RAM with a table top. The longer it is, the more papers and other things you can place on it for work right now. And storage (drive, hard drive, SSD, HDD) is like paper boxes under the table, which stores documents that you do not need at the moment, but will sooner or later.
The more RAM a computer has, the more applications (including those requiring RAM: graphic editors, etc.) it can launch and work in them simultaneously.
The more internal memory a computer has, the more data (movies, music, photos, programs, etc.) can be stored on the computer.
How to find out how much RAM is installed on a Mac
1. Click the Apple logo () in the upper left corner of the screen.
2. Click "About This Mac".
3. The amount of RAM will be indicated in the Memory line in the Overview tab of the window that appears.

The color of the Memory Load graph will give you an idea of how much memory you are currently using. Green indicates that some amount of memory is available. Red, on the other hand, indicates its exhaustion. MacOS starts using a boot disk to expand memory. In this case, Apple recommends closing unused applications or installing more RAM. Yellow means that memory is still available to the system, but the Mac is already starting to start optimizing its work.
5. Pay attention to the Memory column, in which the processes will be allocated in order of higher RAM consumption.

Complete these processes if necessary. To do this, select the required process and click the "×" button in the upper left corner of the "System Monitor" application window.
