Operating Systems
Shell - The user interface that allows users to request specific tasks from the computer. These requests can be made either through the CLI or GUI interfaces.
Kernel - Communicates between the hardware and software of a computer and manages how hardware resources are used to meet software requirements.
Hardware - The physical part of a computer including underlying electronics.
Cisco IOS Access
GUI
A GUI allows the user to interact with the system using an environment of graphical icons, menus, and windows.
A GUI is more user-friendly and requires less knowledge of the underlying command structure that controls the system.
Examples of these are: Windows, macOS, Linux KDE, Apple iOS, and Android.
GUIs can fail, crash, or simply not operate as specified. For these reasons, network devices are typically accessed through a CLI.
PC operating system enables a user to do the following:
Use a mouse to make selections and run programs
Enter text and text-based commands
CLI-based network operating system enables a network technician to do the following:
Use a keyboard to run CLI-based network programs
Use a keyboard to enter text and text-based commands
