Hello!!!!! visitors today I post about User Interface, i think it important for you..
The user interface is what you see when you start a computer.The user interface is comprised with a set of easy to use commands,icons,menus,etc.This is the main source of the work the computer to get something done.Basically there are two types of user interfaces;
1.Command Line Interface
2.Graphical User Interface(GUI)
Command Line Interface
In command line interface,the user has to enter commands through the keyboard to get something done from the computer.The main draw back of this method is that the user should remember the commands and their syntaxes.Any wrong commend will display an error massage on the screen.Another drawback is different commands are used to do the same task for many software applications,resulting a command mix up.
Graphical User Interface(GUI)
Users communicate with the OS and other Software Applications through the interfaces containing icons,buttons,bars,menus and boxes etc.,to work with the computer.The main advantage is that,the users need not remember the commands and syntaxes to execute a job(s) withing computer.
GUI-short for Graphical User Interface,a GUI uses icons and menus to carry out commands such as openings files,deleting files,moving files,etc. A GUI OS is often operated using the mouse however,it also allows keyboard shortcuts or arrow keys to be used navigation.
GUI OS have become very popular because of their ease of use and because it does not require the user to memorize commands that are used with non GUI OS such as DOS or UNIX.
