Study Notes
Introduction to Information Technology
- Software is a set of instructions that enables the physical components of a computer to work together.
- Software is referred to as programs, and computers cannot function without them.
- Software cannot be seen or touched like hardware.
Types of Software
-
System Software: Directly operates computer hardware and provides basic functionality for users and other software.
-
Operating Systems (OS):
- The main program of a computer, loaded first when the computer is turned on.
- Manages computer resources like memory, CPU, printer, and hard drives.
- Provides a user interface for interacting with the computer.
- Offers services to other software.
- Examples include: MS-DOS, UNIX, Windows, Linux, Android, iOS, and Mac OS.
-
Operating Systems (OS):
-
Application Software: General-purpose programs designed for specific applications.
- Customized Software: Programs designed for specific needs, like airline reservation systems.
Operating Systems Explained
- MS-DOS (Microsoft Disk Operating System): A non-graphical, command-line operating system initially released in 1981.
- Windows: A graphical user interface (GUI) operating system developed by Microsoft.
