Computer Engineering Foundations
🔷 What Is Computer Engineering?
Computer engineering is the field that designs and builds the physical parts of a computer.
It combines:
- Electrical engineering → how electricity works inside a machine
- Mechanical engineering → cooling, structure, moving parts
- Computer systems → how components talk to each other
Think of it as the bridge between hardware, energy, and logic.
🔌 Electrical Engineering Basics
Electricity
The movement of electrons through a material.
Voltage (V) — “Pressure”
How strongly the electricity is being pushed.
Current (I) — “Flow”
How many electrons are moving.
Resistance (R) — “Opposition”
How difficult it is for electricity to move through a material.
Power (P)
