swap space

In the world of Linux, efficient management of swap space is a crucial aspect of maintaining optimal system performance, especially in server environments or systems with limited physical memory (RAM). Swap space acts as an overflow area that the system can use when RAM is fully utilized. In this blog, we will delve into what swap space is, how to manage it, and best practices for its filesystem management. Swap space in Linux is a type of disk storage that is used to store data from RAM that is not actively being used. This process allows the system to free up RAM for more immediate tasks. Swap space can be created either as a dedicated swap partition or as a swap file.

If you’ve ever found yourself wondering how much memory your server or desktop has available, the free command in Linux is an indispensable tool. It provides a clear snapshot of the system's memory usage, including RAM and swap space. Understanding the output of the free command can help you monitor your system’s health and make informed decisions about resource allocation. In this article, we'll break down how to use the free command and interpret its output effectively. The free command is a terminal-based tool in Unix-like operating systems such as Linux. It displays the total amount of free and used physical memory (RAM) and swap space on your system.
