Study Notes

USB Connection Standards

USB 1.1 had two speeds: low (1.5 Mbps, 3 meters max cable) and full (12 Mbps, 5 meters max cable)
USB 2.0 increased max speed to 480 Mbps (5 meters max cable)
USB 3.0 (super speed): 5 Gbps (3 meters, unspecified max)
- Different connectors from previous versions (Standard-A, Standard-B, mini-B, micro-B)
- Standard-B and micro-B connectors have different designs for improved signal transmission capabilities.
USB-C connector:
- Connects the device regardless of orientation
- Supports various signals (not just data; video, etc.)
- Smaller than micro-B, symmetrical for easy plugging
USB 3.1 Gen 1 (formerly USB 3.0): 5 Gbps, Renamed
USB 3.1 Gen 2 (formerly USB 3.1): 10 Gbps, Renamed
USB 3.2 Gen 1 (formerly USB 3.1 Gen 1): 5 Gbps, Renamed
USB 3.2 Gen 2 (formerly USB 3.1 Gen 2): 10 Gbps, Renamed
USB 3.2 Gen 2x2: 20 Gbps (Double the 10 Gbps lanes)

Thunderbolt Connections

High-speed serial connections that carry data and power on the same cable
Thunderbolt 1: 2 channels at 10 Gbps each (20 Gbps total throughput)
Thunderbolt 2: Aggregates channels for 20 Gbps throughput
Thunderbolt 3: Uses USB-C connector, supporting 40 Gbps
Supports copper cables (up to 3 meters) and fiber cables (60 meters).
daisy-chaining up to 6 devices for connection extension via additional cables

Serial Connections (pre-USB)

Pre-USB devices used 9-pin and 25-pin serial connections
RS-232 signals for serial communication with devices like modems
DB-9 and DB-25 connectors are still common
Used for configuring devices like switches, routers, or firewalls via command lines.
