Error and Detection

Question 1

What is Error Detection

Answer 1

Error Detection is the detection of errors caused by noise or other impairments during transmissions from the transmitter to the reciever.

Question 2

What is the another name for detection.

Answer 2

Summer

Question 3

Process of Error Detection

Question 4

What is error correction

Answer 4

Error correction is the detection of errors and reconstruction of the original, error-free data.

Question 5

Types of Errors

Answer 5

Single Error
Burst Error

Question 6

Describe Single Error

Answer 6

In single error only one bit of given data unit is changed which either be from 0 to 1 or from 1 to 0

Single type errors are the least likely type of error in serial data transmission

Question 7

Describe burst error

Answer 7

Burst error it means there are more than 2 data unit changed from 1 to 0 or 0 to 1

Question 8

Mention popular techinques of error detection

Answer 8

Simple parity check
Two dimensional parity check
Checksum
Cyclic redunancy check

Question 9

Describe simple parity check

Answer 9

It is the most familiar error detecting code
it is the simplest technique for detecting and correcting errors

Question 10

Describe CRC

Answer 10

CRC is an error detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data.
