Explain Different Types of User Interface

What is a User Interface? Explain its types.

User Interface


User Interface is the set of items on screen to interact with the computer. A user interacts and uses computer with the help of these items. For example, Windows Desktop is an example of user interface. Similarly Dos Prompt is also an example of user interface.

Types of User Interface

There are two main types of user interface:
1) Graphical user interface (GUI)
2) Command line user interface (CLI)

1) Graphical User Interface

Graphical user interface or GUI provides different graphical items like windows, menus, tool bars and icons etc. A mouse or any other pointing device is used to work with these items. Commonly we select different commands from menu or toolbar with the help of mouse. We need not to type commands. We can double click on a file or folder to open it. We can double click on a shortcut to open a program. GUI is very easy to interact the computer.
All versions of Windows, Macintosh, OS/2 and some versions of Unix and Linux provide GUI.

Advantages of GUI - Graphical User Interface:

a) Easy to learn: It is very easy to learn even for beginners or ediots :D
b) Easy to use: GUI based systems are very easy to use becaus of icons, shortcuts, toolbars and menues etc.
c) Use of mouse: Since, we use mouse to select any command from a menue or toolbar, so we feel easier to work on computer.
d) Less typing: There is a very less need of typing commands in a GUI based software. Mostly, you are to point and select commands with mouse.
e) No need to memorize syntax of commands: Syntax is the way of writing that is typing a command so that computer can understand and execute it. Since, in GUI we use mouse button clicks, we need not to memorize command syntax.

2) Command line user interface (CLI)

A command-line interface provides a prompt / place where user types commands for execution. CLI interface is difficult to learn and use. We have to memorize commands. Operating system will not execute the command if there is a small error in typing the command. Dos and some versions of UNIX and Linux provide command-line interface. CLI is character based or textual interface.

Explain different types of storage devices

Topic: Explain different types of storage devices in Computer systems Storage Devices Storage devices are used to store data and instructions permanently. Storage devices are also called secondary storage devices / backing storage devices / external storage devices or auxiliary storage devices. Examples of storage devices include Hard Disk, CD and DVD etc. Why Secondary Storage Devices are Used? Secondary storage devices are used because: Primary memory(RAM) is volatile and temporary. When computer is switched off, all data in ram is erased. Storage devices can store large amounts of data and instructions permanently whereas Primary memory has less capacity of storing data. Types Of Storage Devices There are three main types of storage devices:  Magnetic Tape   Magnetic Disk   Optical Disk   Flash Memory storage devices 1. Magnetic Tape Magnetic tape is the oldest storage device. It is made of plastic coated with m...

Introduction to Algorithms and Algorithmic Notation With Examples

Topic: Introduction to Algorithm and Algorithmic Notation With Examples What is an Algorithm? The step by step procedure to solve a particular problem is called an Algorithm .  A Good Programmer always writes algorithms before developing programs. Algorithmic Notation with example algorithms  Advantages of  writing an Algorithm The process of solving a problem becomes simpler and easier with the help of  algorithm. There are less chance of errors in the program, if we design algorithms before writing our programs in any programming language. We can convert an algorithm into a program of any programming language. It is not dependent on any programming language. Therefore it is easy to understand for anyone even without programming knowledge. What is the Relationship between an Algorithm and a Program Sponsored Links An algorithm is the sequenc of steps to perform a task, whereas a program is the set of statements to perfor...
