Knowing how to check RAM size on a Linux machine is a fundamental task for system administrators and users alike. RAM, or Random Access Memory, acts as the computer’s short-term memory, storing data and instructions that the processor needs to access quickly. Monitoring RAM usage is essential for optimizing system performance, troubleshooting issues, and ensuring the smooth operation of your Linux system.
There are several methods to check RAM size on a Linux machine. One common approach is to use the “free” command, which displays information about memory usage, including the total amount of physical RAM installed on the system. Another option is to use the “vmstat” command, which provides detailed statistics about memory usage, including the amount of free and used RAM.
