Memory usage refers to the amount of random access memory (RAM) being used by a computer system. RAM is a crucial component of a computer, as it stores the operating system, programs, and data that the computer is currently using. When a computer is running low on RAM, it can start to slow down or even crash. Therefore, it is important to be able to check memory usage in order to identify and resolve any potential problems.
In Windows Vista, there are a few different ways to check memory usage. One way is to open the Task Manager. To do this, press Ctrl+Shift+Esc on your keyboard. In the Task Manager, click on the “Performance” tab and then select “Memory” from the left-hand menu. This will show you a graph of your computer’s memory usage over time.
