A value that is computed by a function that is dependent on the contents of a data object and is stored or transmitted together with the object, for the purpose of detecting changes in the data.

A checksum is a value calculated from a block of data, used to detect errors in transmitted data.

See Hash algorithm

The result of a mathematical operation that uses the binary representation of a group of data as its basis, usually to check the integrity of the data.

(IEEE) A sum obtained by adding the digits in a numeral, or group of numerals [a file], usually without regard to meaning, position, or significance. See: check summation.

The sum of a group of data items, which sum is used for checking purposes. Note 1: A checksum is stored or transmitted with the group of data items. Note 2: The checksum is calculated by treating the data items as numeric values. Note 3: Checksums are used in error detecting and correcting. 2.

Internetworking Dictionary A computed value which is dependent upon the contents of a packet. This value is sent along with the packet when it is transmitted. The receiving system computes a new checksum based upon the received data and compares this value with the one sent with the packet. If the two values are the same, the receiver has a high de [..]

A simple error-detection scheme in which each transmitted message is accompanied by a numerical value based on the number of set bits in the message. The receiving station then applies the same formul [..]

In a computer, a summation of digits or bits summed according to an arbitrary set of rules and primarily used for checking purposes. Typically used as an error detection technique in communication and [..]

An algorithm-based method of determining the integrity and authenticity of a digital data object. It is used to check whether errors or alterations have occurred during the transmission or storage of a data object.

Computed value representing the sum of the contents of digital information; used to check whether errors have occurred in transmission or storage of information

(n) a digit representing the sum of the digits in an instance of digital data; used to check whether errors have occurred in transmission or storage

A mathematical calculation applied to the contents of a packet before and after it is sent. If the "before" calculation does not match the "after" calculation, there were errors in the transmission.

A technique for detecting if data inadvertently changes during transmission. The sender simply divides all the data up into two-character numbers, then adds all the numbers together. The receiver m [..]

Used in communications to ensure that the transmission has no errors. It is the numerical sum of all transmitted bytes and is placed at the end of the transmission.

A unique numerical signature dreived from a file. Used to compare copies.

A count of the number of bits in a transmission that is included with the unit so that the receiving end can verify that the entirety of the message has been transmitted.

A checksum is a count of the number of bits in a transmission unit that is included with the unit so that the receiver can check to see whether the same number of bits arrived. If the counts match, th [..]

Checksum is the number of bits in a transmitted unit of data. A checksum is appended to a data unit as a simple error-detection method. The receiving node counts the data bits and compares the result to the checksum, to see whether all bits have arrived. If the numbers match, the transmission was likely complete. TCP and UDP provide checksum count [..]

The sum of a group of data values. Usually transmitted with the data to assist in error detection.

A checksum is a function that creates blocks of data that are used for the purpose of detecting accidental errors that are created during transmission or storage.
