Operating System Installation is the process of setting up a software system that manages computer hardware and software resources. This involves preparing a storage device, such as a hard drive or SSD, and copying the necessary files from an installation medium, like a USB drive or DVD. Users typically follow on-screen prompts to configure settings, such as language and time zone. Once the installation is complete, the Operating System will manage tasks like running applications, handling input from devices, and managing memory. After installation, users can install additional software and customize their system to meet their needs.
