Full Title or Meme
Nearly all computers and other portable devices support a single Universal Serial Bus (USB) for both data and power.
Context
- Legacy serial ports on computers were slow speed and specific to a particular function, like: keyboard, mouse, audio in, audio out, serial RS232 port or printer port.
- Now when a device is connected to a computer is must identify itself so that the computer can recognize that device and ensure it has the correct device driver installed.
- The smart card had a similar serial port with similar functionality.
- New devices for User Identifiers and Attributes are supplied with USB devices so that they can use the common port.
