`
`Graphical Kernel System 11. A computer graphics stan (cid:173)

`graphical images. It functions at the application level
`rather than the hardware level and deals with logical work(cid:173)

`keyboard, mouse, and monitor) rather than with individual
`devices. Graphical Kernel System was developed in 1978
`to handle two-dimensional graphics: the later modifica(cid:173)

`on the screen. The user can select and activate these
`options by pointing and clicking with a mouse or, often,
`with the keyboard. A particular item (such as a scroll bar)
`works the same way for the user in all applications.
`because the graphical user interface provides standard soft(cid:173)

`user's actions (such as a mouse click on a particular icon or
