We Need To Talk About Ones And Zeroes

@mswale, I agree with you.

Your minor premise is that these digital packets successfully travel thousands of miles through AWS’ digital sewer, only to arrive in our homes completely unscathed ones and zeroes.  Facts prove this premise false.  The transmission of digital data over the WWW introduces a number of errors that cause distortion including, without limitation:

1. Jitter, the distortion we are all most familiar with. ​​​​​​
2. Transmission impairments: signal distortion, attenuation
3. Noise:  From EMI which includes RFI, introduced during transmission.

Your statement is incorrect.  The 3 bullet points impact the "signal" at the digital to analog stage.  Not during the digital to digital transmission.

I’m a computer/network/server guy with over 40 years experience in the field.  I was working with networking systems when "ethernet" was still using coax cable and what we call the Internet (i.e. World Wide Web) didn’t even exist yet.

All network transmission protocols, such as TCPIP, Netbios, etc., whether through the Internet, on a corporate LAN, or on your residential WLAN/LAN, have safeguards built in.  They are designed to insure that the data transmitted and received at either end is correct, bit by bit.  If there is any descripancy, it will request that the data packet be resent over and over again, until it is right.  Even a CD player has safeguards to guard against read errors, it’s called oversampling.  (Something nobody even thinks about anymore since it is so reliable.)

And think about it for a minute.  If the data stream is even a little bit wrong, even one bit of data flipped from a 0 to a 1, it would cause corruption that could be a financial transaction to be wrong, or a database to contain the wrong information, or a music file to be corrupted.  And once the data has been digitized, the network transmission/receipt doesn’t differentiate between the type of data (i.e financial, video, scientific, or even music), it is just a string of 0 and 1’s.  That is the beauty of digital transmission.  What is sent is what is received.  And you should be thankful that is correct, otherwise you might find the decimal place on an online credit card transaction to be one place to the right of where it should be.

Jitter, EMI noise, data buffers running dry do to slowness, etc. don’t affect the correctness of the digital data. They effect the ability of the D to A processor and software to convert it back into an analog output.

I am not a networking expert, but when you request a set of data from a provider, you can't receive "noise". You can't receive anything different than what was packaged and sent. You must receive what the provider sent to the last bit. Nothing will be added removed. This "noise" stuff is pure imaginary BS.

@jeffbij I never said sequence of ones and zeros were corrupted.  I said the signal is has errors including jitter, transmission impairments, and EMI.  None of these involve a corrupted sequence, additional or absent digits or sequences.   We are arguing the over semantics regarding the use of the term unscathed.   It is unscathed with regard to the accuracy of the digital sequencing based on the TCPIP protocol but scathed in its timing and signal quality.  

"Timing and signal quality" the go to for the forum expert.

Jesus you lot need to stop

I can't wait until someone comes up with a teleporter that guarantees a bit perfect transfer of someone and watch everyone fight to be the first Brundlefly. 

Carry on. 

All the best,
