What is a CPU?
The Central Processing Unit (CPU) is the main chip in a computer that executes instructions and performs calculations. It’s often called “the brain of the computer” because it controls most operations.

The CPU is the heart of all computation — it takes instructions, processes them rapidly, and runs everything from typing a letter to playing a game.

Input and output devices are hardware components that allow communication between the user and the computer system.

Input Devices: Used to send data to the computer.
Output devices allow the computer to deliver or display results of processed data to the user.

Cooling systems are essential in computers and electronic devices because heat negatively impacts hardware performance, efficiency, and lifespan. Without proper cooling, hardware can overheat, slow down, or fail entirely.

Edge computing is a technology where data processing happens near the data source, such as sensors or IoT devices, rather than sending everything to a centralized cloud or data center.

This approach reduces latency, saves bandwidth, and improves real-time decision-making.
