Parity blocks-computing
« on: May 09, 2011, 03:43:00 am »
Can someone explain the use , & how parity is calculated in a block of data + how parity is calculated in parallel parity ?
I would love to change the world, but they won't give me the source code. ;)

Just need to remember how a parity works in detecting error in transmission, nothing else for AS.

Continuous efforts matter more than the outcome.

You check it. :P

I already checked. Only we should know the use of parity check because of parity bit(s).

check 1.5 Data transmission and networking

e)
recognise that errors can occur in data transmission; explain the use of parity checks, echoing and
check sums in detecting and correcting these errors, and the use of parity blocks to aid self checking

thanx master key !! :D
but i already hav dat !!

Read A Level Computing.

It says about even parity and odd parity checks. Parity bit is before MSB. ;)
