Operatingsystems (OS) are an important software that runs on all computer’s hard drivesor computer chip; the OS manages all ofthe computer’s processes with the software and hardware. This allows people touse a computer for simple actions likerecognising input from a keyboard, while the OS does what you instruct bydisplaying the output on display. As anOS manages all the software and hardware, which need to use the CPU, memory,and storage – the OS controls it all to ensure the programs work and get whatthey need, this is done through the device drivers, which all peripherals andhardware have – it is a program that controls the connection between OS andhardware to make them compatible. They are also the interface that you see onyour screen’s desktop and allows you to use programs, by, for example, clicking on its icons.

Eachdifferent OS has a different interface, features, and customizability.  The first type of operating system was a command line, knownas DOS (disk operating system), where a user would have to type individualcommands for the computer to follow, this means computer users had to haveexpert knowledge in the DOS language. DOS also did not have any graphicalappearance but just text, which awaited the next instruction as shown to theleft. Then, the first Windows OS came out in 1985. This introduced the GUI OS(graphical user interface), this is the type of system we know today that usesan interface with icons and menus to click on with a mouse and pointer, becauseof this, everyone that uses computers does not have to know how to program.

Aswell as the basic functions to allow us to access and use software and hardwarethat the OS carries out, it offers additional features and functions includingutility software to tidy up disk space and ensure security for the system. Themain GUI OS’ include Windows, Mac OS, and Linux for PCs, but other devicesincluding mobile phones and game consoles such as Android, IOS, andPlayStation. Mac OS is Windows’ competitor but is limited to applecomputers which video games are not suitable for, but is used by users withcreative roles such as for music and video editing. Meanwhile, Linux ix theleast popular but is used as an open source OS so technical users can modifythe software to how they want it and download different versions of Linux.Linux is not considered user-friendly asyou must know what you are doing and the OS is much more likely to have errorsdue to a lack of a large, professional company creating and making patches forthe OS.
