Burst Error: because of the noise if one or more number of bits were changed during transmission those type of errors are called as Burst Errors.These type of errors are common in compact disks , magnetic tapes etc..
Example:
0 |

= Before transmission A
0 |

0 |
0 |
0 |
After transmission A=
From the above figure we can observe that three bits were changed these errors are called Burst errors
