UNIT 1 - SOFTWARE

What is software? In the most general sense, software is a set of instructions that tell a computer what to do. These instructions can be anything from a simple game to a complex operating system Categories of software : system software and application software

System Software System software is what makes the computer itself work. It includes the operating system, the most important type of system software, and other programs that help manage the computer's memory, disks, and peripherals. Many of them are free and come installed on your computer. Here are a few examples of system software:

Operating system: The operating system is the most important type of system software. It manages all the other software and hardware on the computer. Common examples include Microsoft Windows, macOS, and Linux. Utility programs: Utility programs help manage the computer's memory, disks, and peripherals. They include disk defragmenters, virus scanners, and backup programs. Device drivers: Device drivers are small programs that enable the operating system to communicate with a particular piece of hardware. For example, a device driver lets the operating system talk to the computer's graphics card.

Application Software
