Question

The operating system offers a graphical vs command line user interface to interact with an electronic device. Compare the graphical user interface and the command line interface in terms of speed, remote access, resource utilization, multitasking, and control. [5 Marks]

Answer 1

Operating offers both Command Line Interface (CLI) as well as  Graphical User Interface (GUI). Both have it's own advantages and disadvantages. Some people prefer GUI over CLI and some otherwise. We will compare the GUI and CLI on the basis of speed, remote access, resource utilization, multitasking and control:

1. Comparison in terms of speed

CLI: In the command line interface we needed only keyboard to navigate and to type which often faster in performance.

GUI : But in GUI we require both keyboard and mouse for typing and for naviagtion respectively. So when we needed to type then we needed to move our hand from mouse to keyboard and vice versa which is often slower than the CLI.

2. Comparison in terms of Remote Access

CLI:  In CLI the remote access (Accessing another computer over the network) is possible. User can all the files devices and files itself from the command line, But to do so you must have known the commands of the command line and it is not easy for the new developer to learn all the commands.

GUI: In GUI also the remote access is possible and it is easy to navigate in GUI with little experience. GUI provides a user friendly environment which consist of buttons, search box, drag and drop etc.

3. Comaprison in terms of Resource Utilization

CLI: A CLI is a tool that uses minimal resource to open the command line and to work in the command line.

GUI: A GUI is a heavy tool which needed more resources because of the componenets in the GUI that require loading such as icons and fonts and if heavy graphics then it needed to be rendered before loading which causes so much resource need.

4. Comaprison in terms of multitasking

CLI: In command line environment we can peform the multitasking but they don't provide ease and ability to view multiple process on the screen at once.

GUI: GUI provides all these features that the user can view, control, manipulate, and toggle through multiple process and files at same time.

5. Comparison in terms of control

CLI: CLI provides full control over both the file and operating system for user but it's not easy, as to do so we needed to know the required commands and it is not as user friendly as a GUI.

GUI: GUI provides a user friendly environment to users and offer lot of access to files, software and operating system as a whole. Because of it's user friendly nature GUI is utilised by more user than CLI.

I hope this will help.
