Icon – definition and examples
An Icon may refer to a pictorial symbol we use in a GUI (graphical user interface). We sometimes use icons in web documents to identify a program, device, folder, or file. For example, an icon may represent a modem, printer, or a drive. When we click on the icon, we activate it, i.e., either an operation starts, or a window opens.
If I describe somebody as an icon, I am saying that they are important as a symbol of something. For example, Picasso and Marilyn Monroe were icons of modernism and mid-20th-century Hollywood respectively.
We sometimes use the term when referring to a depiction of Jesus Christ, the Virgin Mary, or a saint painted on a wooden panel
Collins Dictionary has the following meaning of the term when referring to an image on a computer screen:
“An icon is a picture on a computer screen representing a particular computer function. If you want to use it, you move the cursor onto the icon using a mouse.”
Icon on a computer screen
When they appear on computer screens, icons are small pictures that represent objects or programs.
They are extremely useful in Windows applications. They are useful because when you click with your mouse, you can shrink the whole window into a tiny icon. We also refer to this procedure of shrinking a window as ‘minimizing.’
When you want to re-display the window, you simply move your cursor to the icon and click. You may have to click just once or sometimes twice. We also use the terms ‘maximizing‘ or ‘restoring‘ when referring to re-displaying a window.
Types of icons
There are standardized electrical device icons, desktop metaphor icons, and brand icons for commercial software.
Icons for standardized electrical devices
Some common computer icons come from the broader field of standardized icons. These are icons that we have been using across a wide range of electrical equipment.
For example, many electrical devices use the USB and power symbols.
Most electronic and electrical devices have standardized icons as safety features. They also help owners know what specific buttons and plugs are for and where things go.
Icons may be hyperlinks that represent office objects or things in our desktop environment. For example, they may represent an inbox, printer, trashcan, folder, or a file.
A hyperlink is a text or image that takes the online visitor to another part of the web page, another page in the same website, or another website. A hyperlink on your desktop, if you click on it, will take you to another part of your system.
These desktop metaphors originally enabled users who were familiar with office procedures to navigate their computer desktops intuitively.
Regarding these desktop metaphors, Wikipedia says:
“The icons stand for objects or functions accessible on the system, and enable the user to do tasks common to an office space.”
Brand icons for software
We can often identify third-party software programs that are available on our computer screens as icons. These brand icons commonly appear on the screens of brand new computers. In other words, they form part of a bundle of products that come with new devices.
They are just like the hyperlink icons described above in that they represent functionality that is accessible in the system.
Companies will spend money on a brand icon because it represents a particular commercial product. They will pay commercial artists to design them.
The term ‘brand‘ may mean the name of a product, the image of a company, a logo, or a slogan.
