A Graphical User Interface (GUI) is an arrangement of interactive components such as icons and other graphical objects that assist a user to interact with computer software, such as an operating system. A GUI is believed to be more user-friendly than a command-line interface which is text based, such as MS-DOS, or the shell of Unix-like operating systems.
A GUI is also an interface through which a user relates with electronic devices such as computers, hand-held devices as well as other appliances. This interface displays information graphically and related user controls. This is as opposed to text-based interfaces, where data and commands are in text format. GUI representations are manipulated by using a pointing device such as a mouse, trackball, stylus or – alternatively – a finger on a touchscreen.
The requirement for GUI became apparent as the first human/computer text interface was through keyboard text creation using what is named a prompt (or DOS prompt). Commands were typed onto a keyboard at the DOS prompt in order to introduce responses from a computer. Using these commands, and the need for exact spelling, created a cumbersome and inefficient interface.
What are the benefits of a GUI?
The major advantage of a GUI is that systems which make use of one are available to individuals of all levels of knowledge, from an utter beginner to an advanced software developer or other tech-savvy people. GUIs make it easy for anyone to:
- Open menus,
- Move files,
- Launch programs, or
- Search the Internet – without having to tell the computer using the command line – to carry out a function.
GUIs also give instant feedback. By click on an icon, this action will open it up in real-time. By using a command-line interface, you won’t know if it’s a valid entry until you hit <ENTER>. If it’s not valid, nothing will happen.
A computer with a GUI that is well designed can be used by almost anybody. This is regardless of how technically savvy the person might be. Consider the cash management systems, or computerised cash registers, that are used in stores and restaurants today. Inputting information is as easy as pressing numbers or images on a touchscreen to place orders and calculate payments.
The process of inputting information is simple and practically anybody can be trained to do it from SEO’s to web developers and marketers. The system can store all the sales data for later analysis in countless ways as well as for digital marketing purposes. This type of data collection was far more labour-intensive before GUI interfaces.
Here are some more benefits or advantages of GUI Interface:
- A GUI interface requires just a click on the simple picture or image to use its functionalities.
- A GUI interface is very easy to use by a beginning – as we’ve said before – because it is user friendly and easy for any person to use who want to have better interface for their digital marketing strategy.
- Simple icons in the GUI interface use numerous instructions in the back-end. This means that it is easy for the programmer to code in GUI as compared to other non-GUI-based programming languages.
- Programmers or users do not need to understand the workings of a computer system in order to successfully navigate a GUI.
- A GUI looks very attractive and multi-coloured and it is much better than command-driven interface which has many drawbacks.
- The user can switch quickly between tasks on the GUI interface.
- Fullscreen interaction is also possible with quick and wholesome access to anywhere on the screen.
GUIs are utilised for the majority of computer operating systems, mobile operating systems as well as software that is on the market today. Although a few operating systems, such as Linux, still use command-line interfaces, this feature makes them less mainstream as they are only suitable for those who have an in-depth knowledge of commands and programming.
