🔹 What Is Computing?

Computing refers to the process of using computers to:

• Receive data (input)

• Process data using algorithms

• Store data

• Produce meaningful results (output)

At its core, computing combines:

• Hardware (CPU, memory, storage)

• Software (operating systems, programs)

• Algorithms (logical problem-solving steps)

• Data structures (ways to organize data efficiently)

🔹 Why Computing Matters in Engineering

Engineering problems are often:

• Data-heavy 📊

• Repetitive 🔁

• Complex 🔬

Computing allows engineers to:

• Automate calculations

• Simulate physical systems

• Analyze large datasets

• Optimize designs

• Reduce human error

Python bridges the gap between engineering theory and practical computation.
