Checking memory size in Red Hat is a crucial task for system administrators to ensure optimal performance and resource allocation. Memory, also known as RAM (Random Access Memory), plays a vital role in storing data and instructions that the CPU needs to process. By monitoring memory size, admins can identify potential bottlenecks, prevent system crashes, and make informed decisions about hardware upgrades or resource optimization.
There are several methods to check memory size in Red Hat systems. One common approach is through the command line using the “free” command. Running “free -m” displays memory information in megabytes, providing details about total memory, used memory, and available memory. Additionally, the “top” command can be used to view real-time memory usage, including information about processes and their memory consumption.
