COMPUTER FUNDAMENTALS

Detailed explanation-1: -The operating system is usually factory-installed, but because it is a general requirement, this term is used for additional software apart from the bare necessary amount, usually from other sources (or the operating system vendor).

Detailed explanation-2: -Most system software comes pre-installed on a computer with the operating system. Though there are ways to install new operating systems on a device, including its system software, it can be a more complicated process compared to application software.

Detailed explanation-3: -Preloaded apps are mobile apps which are installed and licensed on new devices before they’re purchased. In other words, they’re apps that new device owners can interact with right out of the box.

Detailed explanation-4: -An operating system (OS) is the program that, after being initially loaded into the computer by a boot program, manages all of the other application programs in a computer. The application programs make use of the operating system by making requests for services through a defined application program interface (API).
