Software development is the process of designing, writing, testing, and maintaining the programs that run on computers and phones. Programming is writing the actual instructions, called code, using languages like Python, JavaScript, or Java.
How does it work?
Developers break a problem into steps, write code to solve it, then test and fix errors (called 'bugs'). Teams often use version control to track changes and tools that automatically test and release new versions of an app.
Why does it matter?
Every website, app, and digital service exists because someone built it with code. Software powers business, communication, entertainment, and nearly every modern industry.

Did You Know?
Most software is built in small steps: write code, test it, fix bugs, repeat. 'Debugging' is a normal, expected part of the job.
