The amount of RAM (random access memory) in a computer system is a critical factor in determining its overall performance. RAM is used to store the operating system, applications, and data that are currently being used by the computer. The more RAM a computer has, the more programs and data it can handle simultaneously without slowing down.
There are several ways to check the amount of RAM installed on an Ubuntu system. One simple method is to use the system monitor. To do this, open the system monitor by pressing the “Super” key (the key with the Windows logo on it) and typing “system monitor”. Once the system monitor is open, click on the “Resources” tab and then look for the “Memory” section. The amount of RAM installed on the system will be displayed in the “Installed” field.
