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.
On retrieval, the calculation is repeated and, in the event the check values do not match, corrective action can be taken against data corruption. CRCs can be used for error correction (see bitfilters).
CRCs are so called because the check (data verification) value is a redundancy (it expands the message without adding information) and the algorithm is based on cyclic codes.
CRCs are popular because they are simple to implement in binary hardware, easy to analyze mathematically, and particularly good at detecting common errors caused by noise in transmission channels. Because the check value has a fixed length, the function that generates it is occasionally used as a hash function.
The CRC was invented by W. Wesley Peterson in 1961; the 32-bit CRC function, used in Ethernet and many other standards, is the work of several researchers and was published in 1975.
The 7th Central Pay Commission (7CPC), constituted in February 2014 to review the principles and structure of emoluments of all central government civilian employees including defence forces in India, submitted its report on 19 November 2015. p 95,para 6.1.2–3 7CPC's recommendations affects the organization, rank structure, pay, allowances and pension, of 13,86,171 armed forces personnel. page 105, para 6.2.2
Following the submission of the 7CPC report, the Chiefs of Staff of the Armed Forces in a submission to the Government stated that the recommendations of 7th CPC are anomalous, discriminatory, and at variance with historical parities.
The anomalies identified by the armed forces are about use of different principles, policy, and formula by the 7CPC for determining armed forces pay, allowances, level, rank equivalence, pension, and status in comparison with the civil services, including defence civilians, police and intelligence services. These anomalies they have argued affect morale, command and control, and cohesion.
