O.S have drastically improved in the sence of interface as the engineers work tirelessly to make more user friendly operating systems.
Earlier versions of O.S were tedious and cumbersome to work with since commands were executed by typing a string of codes or a line of commands.
One had to remember every element of the codes for a command to be executed perfectly.
Unlike current O.S which utilizes work area, pictorial commands known as icons and execution of the commands is done by a pointing device.
Commonly used operating systems today include
- Windows O.S developed by Microsoft .
- Mac O.S developed by the Apple company.
