- Differentiate between personal, enterprise and workgroup operating systems
- Identify the components of a graphical user interface (GUI)
- Recognize command line interface options, parameters and commands
1. Computer Operating Systems: Managing Hardware and Software Resources
This lesson will introduce you to computer operating systems and help you figure out the difference between application and operating system software. Also, we will learn the difference between a desktop and wallpaper.
2. OS Functions: Security, System Management, Communication and Hardware & Software Services
The operating system (or OS ) is the brain of a computer and manages its functions, including systems management/monitoring, communication/networking services management, security services management, and hardware/software services management.
3. Enterprise, Workgroup & Personal Operating Systems
While every computer needs an operating system, different devices and different users need different functionalities. Learn about the different types of operating systems.
4. What is a Graphical User Interface (GUI)? - Definition, Components & Examples
If you use a computer or smart phone, you have used a GUI. In this lesson we will find out what a GUI is, quickly trace its history, and cover its key components. We'll also take a look at some current examples.
5. Command Line Interface: Commands, Parameters & Options
Despite the popularity of graphical user interfaces, command line is still widely used. In a command-line interface, a user interacts with a computer by typing in lines of text. Learn about the use of commands, parameters and options.
