Detailed explanation-1: -The idea of operating system hardening is aimed at minimizing a computers exposure to current and even future threats by configuring the operating system and removing applications and devices that are unnecessary. In the modern world, security takes an increasingly predominantly important role.
Detailed explanation-2: -The operating system divides memory into “pages". They’re typically 4KB in size. The operating system keeps track of those pages in a table. By counting them we can determine how much memory is used or free.
Detailed explanation-3: -Memory management is the process of controlling and coordinating a computer’s main memory. It ensures that blocks of memory space are properly managed and allocated so the operating system (OS), applications and other running processes have the memory they need to carry out their operations.
Detailed explanation-4: -Linux is a great way to breathe new life into an old machine. Why? Because most Linux distributions have lower system requirements than Windows, the operating system found on most PCs sold in stores. Linux typically puts less strain on your computer’s CPU and doesn’t need as much hard drive space.
