System Memory Usage can be checked in several different ways, depending on the operating system you are using.
Windows:
If you are using a Windows operating system, start by right-clicking on the Taskbar and selecting Task Manager. Once the Task Manager window opens, click on the Performance tab, which will give you an overview of your computer’s memory usage. This includes information about the amount of dedicated and shared memory being used, as well as the total system memory that is available. You can also click on the Memory tab for a more detailed breakdown including the processes currently running on your machine and their memory usage.
Mac OS X:
If you are using Mac OS X, open up the Activity Monitor application. You can find it in Applications > Utilities. The Activity Monitor shows you an overview of your computer’s system memory usage including information about the processes currently running and their memory consumption. You can also find out more about the memory usage of each process by clicking on the Process Name column.
Linux:
If you are using a Linux-based operating system, start by entering the command top in a terminal window. This command will show you an overview of your system memory usage with information about the processes currently running, their CPU utilization, and their memory usage. You can also enter the command free to get more details about your memory usage.
Other tools to keep track of your system memory usage include third-party applications such as Windows Reliability Monitor, NETGEAR Genie, and RAMMon. Additionally, there are many websites and mobile apps that you can use to monitor your system memory usage.
No matter what operating system you are using, the most important thing to remember is to keep an eye on your memory usage and make sure that you have enough free memory for your computer to perform its tasks. If you notice that your system is constantly using more memory than it should, then it may be time to consider upgrading your computer’s memory.
