Error detection at the data link layer is achieved by?
The correct option is C Cyclic redundancy codes
Error detection at the
data link layer is achieved by Cyclic redundancy codes.
Error detection and
correction. Beside framing, data link layers also include mechanisms to detect
and even recover from transmission errors. ... The simplest error detection
code is the parity bit, which allows a receiver to detect transmission errors
that have affected a single bit among the transmitted N + r bits.
It allows the receiver to
inform the sender if a frame is lost or damaged during transmission and
coordinates the retransmission of those frames by the sender. • Error control
in the data link layer is based on automatic repeat request (ARQ). Whenever an
error is detected, specified frames are retransmitted.
A cyclic redundancy check
(CRC) is an error-detecting code commonly used in digital networks and storage
devices to detect accidental changes to raw data. Blocks of data entering these
systems get a short check value attached, based on the remainder of a
polynomial division of their contents.
Data is transferred in
the form of bits between two or more digital devices. There are two methods used
to transmit data between digital devices: serial transmission and parallel
transmission. Serial data transmission sends data bits one after another over a
single channel.
