Let the message be M : 1001 0001 and the generator function is G : 1001
Solution :
CRC sender
<u> </u>
1001 | 1001 0001 000
<u> 1001 </u>
<u> 0000 0001 </u>
1000
<u> 1001 </u>
0001 000
<u> 1 001 </u>
0001
Here the generator is 4 bit - 1, so we have to take three 0's which will be replaced by reminder before sending to received--
eg 1001 0001 001
Now CRC receiver
<u> </u>
1001 | 1001 0001 001
<u> 1001 </u>
0000 0001
<u> 1001 </u>
1000
<u> 1001 </u>
0001 001
<u> 0001 001 </u>
0000
No error
Answer:
A bar code reader scanner captures the pattern in a barcode and sends it to the computer, where special software translates the pattern into meaningful data.
Explanation:
A barcode reader is a handheld device that captures and reads information that is contained in a bar code. It consists of a scanner, a decoder and a cable that connects the barcode reader into a computer. This scanner works by directing a beam or red light across the black and white elements of a barcode. This amount of light energy that is reflected back is measured and converted into electrical energy which is then converted into readable data by the decoder and forwarded to a computer.
