## Body

### Overview and Functionality
The **PlayStation 2 Network Adaptor** was an expansion peripheral that allowed the PlayStation 2 to connect to the internet. It slotted into the console’s **expansion bay** (located on the rear of original models) and provided an **RJ45 Ethernet port** for broadband connectivity. This enabled online multiplayer, web browsing via the PlayStation 2’s **Linux Kit** or **NetFront** browser, and access to early online services.

### Hardware and Design
- **Physical Connection**: The adaptors plugged directly into the PlayStation 2’s expansion port, which was absent in later slim models.
- **Ethernet Port**: Featured a standard **RJ45 connector**, requiring a wired broadband connection (no Wi-Fi support).
- **Hard Drive Integration**: The **PlayStation 2 Hard Drive** (a separate accessory) connected to the console through the Network Adaptor, providing additional storage for games like *Final Fantasy XI* and *SOCOM: U.S. Navy SEALs*.

### Compatibility and Limitations
- **Console Models**: Only compatible with the original "fat" PlayStation 2 (SCPH-30000 to SCPH-50000 series). Slim models (SCPH-70000 and later) lacked the expansion bay.
- **Game Support**: Required for online play in titles such as:
  - *SOCOM: U.S. Navy SEALs* (2002)
  - *Final Fantasy XI* (2003)
  - *Twisted Metal: Black Online* (2002)
- **Regional Variations**: Sold in different regions under the same name, with no significant hardware differences.

SIE was established in **November 1993** and rebranded in **April 2016**, with headquarters in **Tokyo, Japan**, and later **San Mateo, California**. The company’s focus on online gaming infrastructure made the Network Adaptor a key part of its early internet strategy.

### Legacy and Impact
