What are Operating Systems?
Operating systems are the central nervous systems of a computer. They provide a large platform that allows other software or hardware platforms to run. This is by essentially acting as a bridge between the physical components and applications. Operating systems are capable of performing basic tasks, such as recognizing input from the keyboard, displaying data on the screen, and controlling peripheral devices such as disk drives and printers. They also manage basic security functions ensuring that there is no unauthorized access to the computer.
An operating system essentially gives you access to these smartphones and computers and allows them to perform all the basic functions we are used to. Devices come with an operating system installed that is usually specific to the manufacturer, but users can sometimes switch to the operating system of their choice depending on their device.
Operating systems allow for simultaneous use of applications and connect with the CPU for storage and memory allocation. Operating systems often require updates to keep things running smoothly, to fix bugs and to patch security vulnerabilities. Most device manufacturers will provide upgrades on their end without the need for users to purchase any additional packages or hardware.
