This helps the OS use memory efficiently and avoids large empty spaces.<br /> * &#039;&#039;&#039;Segmentation:&#039;&#039;&#039; Instead of fixed-size pages, &#039;&#039;&#039;segmentation&#039;&#039;&#039; breaks a program into logical pieces called &quot;segments.&quot; These segments might be different sizes, like one segment for a program&#039;s code, another for its data, and another for its settings. This is more like how a human would think about parts of a program.<br /> <br /> Both paging and segmentation are ways the OS organizes memory to make sure programs can run even if they need a lot of space, and to keep different programs&#039; data separate.<br /> <br /> &#039;&#039;&#039;Bibliography:&#039;&#039;&#039;<br /> <br /> * &#039;&#039;&#039;Paging in Operating System.&#039;&#039;&#039; (n.d.). &#039;&#039;GeeksforGeeks&#039;&#039;.
