or

Cable Connections

USB

Ethernet

Internal motherboard connections

5. Semiconductor Components

Examples include:

CPU – Central Processing Unit

GPU – Graphics Processing Unit

MPU – Microprocessor Unit

NPU – Neural Processing Unit (AI)

APU – Accelerated Processing Unit

EPROM/Flash Memory – Stores firmware

6. Analog Electronics

Basic components:

Resistor (R) – Limits current and creates attenuators.

Capacitor (C) – Stores electrical energy.

Inductor (L) – Filters electrical signals.

Bipolar Junction Transistor (BJT) – Amplifies or switches signals.

Operational Amplifier (Op-Amp) – Signal amplification.

8. Product Examples

This architecture is used in many products:

Smartphones

Tablets

Smartwatches

Smart speakers

Digital cameras

Video game consoles

Vehicle infotainment systems

Smart home LED lighting

Smart wall outlets

What Does It Mean If You Don't Understand It?

If you do not understand how the technology works, you may:

Connect the wrong power supply.

Use the wrong voltage or frequency.

Install incompatible hardware.

Select incorrect software or firmware.

Misunderstand the products, Technique specifications.

Make design or troubleshooting mistakes.

Increase the risk of product failure or safety issues.

The solution is to learn the technology step by step:

Input Power (AC)

Power Supply (AC → DC)

Electronic Components

Signal Processing

Software & Firmware

Communication (Wi-Fi, Bluetooth, USB, Ethernet)

Cloud Services

Applications
