Week 3: Basics of Computer Software

Introduction to Computer Software: Overview of operating systems, and applications.

Computer software refers to a set of programs, applications, and data that enable a computer to perform specific tasks. There are two main types of computer software: system software and application software.

System software includes operating systems, device drivers, and utility programs that manage and control the computer’s hardware and software resources. The most important system software is the operating system, which is the primary interface between the user and the computer. The operating system manages the computer’s resources and provides a user-friendly interface for running applications and managing files.

Operating Systems: Operating systems are the backbone of a computer system. They manage all the hardware and software resources of a computer and provide a user interface for users to interact with the computer. There are many different types of operating systems available, including:
