Long story short, practice tests are boring, and boring times provoke doing boring tasks, such as learning howto decode barcodes.
The coputer read sheet contains a 4 by 8 square matrix, with certain squares blackened.
Hmm, 8 squares, sounds like 8bit binary. Kinda. This is what I learnt, remembering that I was in an exam so I couldn’t use outside world help.
This is the barcode if it was written as binary (the first few attempts of me decoding it failed because I was reading it upside down).
00001101 | B
00010101 | C
00000001 | D
(3349)
Now to read is quite simple, you get rows B and C and put next to each other, which make a 16 bit binary code.
0000110100010101
Which equals 3349, correct according to the number under the barcode. Now the next problem is what are rows A and D for. I presume they are for check sum, row D is a simple, “this row should equal one” check, but row A is left. If anyknows how the checksum works, comments would be nice. Btw, this was from a QCS prac. exam, I thought they would use something a little more harder.
ever heard of a “life”?
its when you go outside, play sport and shit? talk to friends in real life, not just on the net?
you should fuckin invest in one…
I heard you can buy one from Kmart, got any qoutes?
I never seen so much coolness, especially someone who won’t even put their name up
yeah go on put your name up. show us how awsome you relly are.
Really, not relly, you illiterate fucktard.
life can be found next to the canned goods at any good IGA near you.
another place to find a life is with your mum…in soviet Russia
PS. This blog is not the place to discuss hatred, or to judge people. I do go outside, and do talk to people off the internet, I’m just not in your life. I do admit computing is a major part of my life, it’s my hobby / sport. Go find somewhere else to troll.
your the illiterate fucktard, you didn’t even pick up that awesome was spelt wrong.
you can spell quotes pretty good to.
but then again i am the illiterate fucktard that spelt both ‘awesome’ and ‘really’ wrong, so i guess im just douchebag!
I’m not going to run everything through a spell checker. Reading barcodes is more my thing. Go get a life, or troll somewhere else. Mr Booth impersonator.
