1. Overview

Adapters and converters are essential components in modern computing systems, enabling interoperability between devices with different interface standards, voltage requirements, or data formats. Adapters primarily facilitate physical or electrical connection compatibility, while converters transform signals or power between different protocols or forms. These devices play a critical role in ensuring seamless integration across evolving hardware ecosystems, supporting legacy systems, and enabling cross-platform functionality in professional and consumer environments.

2. Main Types & Functional Classification

Type	Functional Characteristics	Application Examples
Interface Adapters	Convert between physical connectors (USB-C, HDMI, VGA, etc.)	Laptop docking stations, peripheral connectivity
Protocol Converters	Translate communication protocols (USB-to-Serial, SATA-to-USB)	Industrial automation systems, data recovery tools
Power Adapters	Convert voltage levels and AC/DC power formats	Laptop chargers, international travel converters
Display Converters	Convert video signals (HDMI-to-VGA, DisplayPort-to-DVI)	Conference room projectors, multi-monitor setups
Network Adapters	Bridge different networking standards (Ethernet-to-WiFi, fiber-to-RJ45)	Enterprise network infrastructure, IoT gateways

3. Structure & Composition

Typical adapter/converter devices consist of:

• Enclosure: Plastic/metal housing for EMI shielding and mechanical protection
