Today, we are going to cover the different domains of software applications. Can anyone tell me what system software includes?
Isn't it just operating systems?
Great start! Yes, operating systems like Windows, macOS, and Linux are part of system software. They manage overall system resources and facilitate hardware operations. What other types can you think of?
What about compilers and interpreters? They take our code and run it, right?
Exactly! Compilers and interpreters convert source code into executable files. They are crucial for software development. Now, can anyone define what application software does?
Application software helps end-users perform tasks, like accounting or word processing.
Spot on! Applications like ERP and CRM software are designed to support business processes. Let's summarize key types: System software serves as the backbone for hardware management, while application software directly meets user needs.

Now let's shift gears to the economic aspect. How have software and hardware costs changed over the years?
I think hardware used to be way more expensive than software, right?
Correct! Initially, hardware was the dominant cost, but with advancements in technology, hardware costs have diminished significantly, while software development costs have escalated. Can anyone explain why this is significant?
If software is now the major expense, it means we need better engineering practices to control those costs.
Exactly! Poor quality or buggy software can result in financial losses and reputational damage. We must prioritize effective software engineering processes.
