THINGS TO NOTICE

Any bits that are zero are always ignored. The number of bits does not change the parity either.

The receiver must know not only whether the message was sent using even or odd parity, but also whether the parity bit is the first or last bit.

THINGS TO TRY

Set slow-motion to 0.5, click random, and then click go.

Set the parity and placement to a type you wish to drill, and click setup. Work each step by hand, and then click the step button to check your answer.

Applets on this website were written by Teresa Carrigan in 2004, for use in computer science courses at Blackburn College, with the exception of the Fireworks applet. The applets made with NetLogo require Java 1.4.1 or higher to run. The applets made with NetBeans require Java 1.4.2 or higher to run. Applets might not run on Windows 95 or Mac OS 8 or 9. You may obtain the latest Java plugin from Sun's Java site.
