Evolution of Computer Ports
Introduction
Modern USB ports are prevalent due to their superior utility compared to older port systems.
Historical challenges of connecting devices in the 80s and 90s.
Legacy Port Types
PS/2 Port
Introduced in 1987 on the IBM personal system SL2.
Replaced the DIN connector from the 1950s.
Used for dedicated keyboard and mouse connections on PCs.
Less common now due to USB's robustness and ease of use.
Still offers advantages in specific scenarios, such as BIOS compatibility and security setups where USB ports are disabled.
Apple Desktop Bus
Introduced in 1986, supporting devices like joysticks and graphics tablets.
Replaced by USB with the release of the original iMac.
Serial Port
Known as the OG do-it-all connection, transmitting data one bit at a time.
Used for various connections including modems, PC to PC connections, and smart home hubs.
Limited by low data transfer speeds and cumbersome design.
Parallel Port
Primarily used for printers and known as printer port or 1284 port.
More efficient than serial ports for data-heavy devices but replaced by USB due to synchronization challenges in parallel connections.
Game Port
Common in the 80s and 90s for connecting joysticks and game paddles.
Often found on sound cards as an added feature.
Eventually outmoded by USB due to limited button support and analog vulnerability to electrical noise.
Conclusion
USB's digital nature and versatility led to the decline of these older technologies.
Viewer engagement with historical port usage encouraged for future episodes.
