The Computer: Fast Information Machine ⚡
### How does a computer think?
A computer is an electronic device that accepts raw **Data (Input)**, processes it at high speed (**Processing**), and produces meaningful **Information (Output)**.
The **IPO Cycle**:
$$\text{Input} \longrightarrow \text{Processing (CPU)} \longrightarrow \text{Output}$$
$$\downarrow$$
$$\text{Storage (SSD/Hard Drive)}$$
Core Takeaway: Computers take input, process with CPU, output results, and store data in memory.
