What is the error detection technique that can detect errors with only one bit?
(a) simple parity check (b) two-dimensional parity check (c) crc (d) checksum
What do you mean by single bit error correction?
A special system of multiple parity bits (e.g. Hamming parity) that allows not only error detection but limited error correction.Ordinary single bit parity can detect reliably single bit errors.Hamming parity can correct single bit errors and detect reliably double bit errors.
What is the verb for detection?
The verb for detection is detect.Other verbs are detects, detecting and detected.Some examples are:"I detect a foul smell in the air"."He detects something"."My metal detector is detecting something"."As usual, the detector only detected junk".
What is error control in networking?
An error-detection code by itself does not control errors, but it can be used to request repeated transmission of errored code words until they are received error-free. This technique is called ARQ. In terms of error performance, ARQ outperforms forward error correction (FEC) because code words always are delivered error-free (provided the error-detection code doesn't fail). However, this performance does not come free of charge - we pay for it with decreased throughput. The chief advantage of ARQ is that error detection requires simpler decoding than error correction. ARQ also is adaptive because it only re-transmits information when errors occur. On the other hand, ARQ schemes require a feedback path that may not be available.
Suppose that noise changes the data unit 01110000 to 01110011 what will detect the error?
Longitudinal redundancy checking LRC only
Why does the the florescense appear in the chaneels only n not in the form of moving bands While performing Gel electrophoresis For DNA detection?
Only the bands should show fluorescence, you must be doing the technique wrong..
What sort of hazardous gas detection options are available?
Well there is only one option and that is get a gas detector. Prices really vary on what brand and how many gasses it can detect. So thats about it you need to know
Is there a way to detect and earthquake?
Yes, earthquake is the breakdown of geological structure. There is the pre-warning wave emitted out before the start of the earthquake. However, the detection can only give a warning at a short period of time.
Two communicating devices are using a singlebit even parity check for error detection. The transmitter sends the bye 10101010 and because of channel noise the receiver gets the byte 10011010. Wil?
The receiver won't detect the error, as a parity check bit only detects inversion of an odd number of bits.
Why is PCR important in many aspects of biotechnology?
PCR is important technology in field of molecular technology This technique is mainly used to create multiple copies of DNA for particular DNA sequence Now, its application ranges widely from disease detection like in leukemia,lymphomas for detection of specific gene sequence in forensic analysis,to clone(to produce no of copies) of DNA of particular stretch. It is the only trustworthy and definite technique that can be used in above techniques that is why it has wide scope in biotechnology.
Can preliminary breathe test detect marijuana?
no, it can only detect the alcohol
What are the limitations of Hamming Code?
Hamming code handles only single-bit errors-two or more errors will cause an incorrect syndrome value. It can detect double bit error but not corrected
