Meaning – The term graphical user interface, refers to the type of computer interface consisting of a visual metaphor of a real-world scene, often of a desktop. Within that scene are icons, representing actual objects, that the user can access and manipulate with a pointing device.
Initially, computers and other electronic devices relied on the command line to get tasks done for the user. However, casual users found this very difficult to understand and as such, the PC market became limited to just enthusiasts and experts. However, Apple and Microsoft changed the game when they introduced a GUI based operating system for their devices (macOS and Windows respectively), and this was immediately acceptable to the general public, as they could now see and interact with various elements within the operating system in order to get their tasks done.
Example of usage – “Although he was an expert developer and programmer, he preferred GUI based PCs for his daily use.”
