What is the data rate of a POTS connection?

  1. 28 KBps

  2. 56 KBps

  3. 128 KBps

  4. 512 KBps

The correct answer is: 56 KBps

A POTS (Plain Old Telephone Service) connection refers to traditional analog phone lines. The data rate for a POTS connection is 56 KBps, which is much slower than newer digital connections like DSL or cable modems. Option A, 28 KBps, is too low and does not accurately reflect the data rate of a POTS connection. Option C, 128 KBps, and D, 512 KBps, are both much higher data rates and are not applicable to POTS connections.
