What main purpose does software serve?

Software primarily serves the function of facilitating tasks on computers. This encompasses a broad range of applications, from operating systems that manage overall system functionality to specific applications that enable users to perform designated tasks such as word processing, data analysis, graphic design, and more.

While managing hardware resources is an essential function of system software, it is more of a supportive role to ensure that the software can perform its primary task—helping users accomplish their objectives efficiently. Similarly, designing user interfaces and developing network connections are specialized aspects of software development and operation, but they fall under the larger umbrella of software's role in enabling users to complete tasks effectively. The core purpose remains centered around empowering users to effectively interact with technology and execute various functions.
