checksum
a digit or character, derived by applying a suitable algorithm to some data, used to check whether errors have occurred in transmission, storage or data entry
checksum
To compute a checksum
checksum
A value that is computed and that depends on the contents of a set of data Checksums are stored or transmitted with the data The checksum is used to detect if the data has been altered during transmission or when being stored and retrieved Receiving programs recompute the checksum to compare with the checksum sent or stored with the data Checksums may be more than one digit They are not always the result of addition but may be the result of one or more computations involving addition, subtraction, multiplication, or division
checksum
A calculated value used to test data for the presence of errors that can occur when data is transmitted or when it is written to disk
checksum
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
checksum
A method of providing information for error detection, usually calculated by summing a set of values The checksum is usually appended to the end of the data that it is calculated from so that they can be compared For example, Xmodem, a popular file-transfer protocol, uses a 1-byte checksum calculated by adding all the ASCII values for all 128 data bytes and ignoring any numeric overflow The checksum is added to the end of the Xmodem data packet This type of checksum does not always detect all errors In later versions of the Xmodem protocol, cyclical redundancy check (CRC) is used instead for more rigorous error control (Ref: Dyson, Dictionary of Networking)
checksum
A value which is the result of adding specific binary values A checksum is often used to verify the integrity of a sequence of binary numbers
checksum
Used in error detection, a checksum is a computation done on the message and transmitted with the message; similar to using parity bits
checksum
A number that represents a larger group of numbers in order to check for errors in data transmission It is commonly used when downloading a program, as well as in error control protocols The checksum is the result of a mathematical equation, such as adding all the numbers in a block together (although it is usually more complex than that)
checksum
The integer result of a 16-bit cyclic redundancy computation on the the bytes of a logical record segment, excluding the checksum result itself and any bytes (e g , the logical record trailing length) that follow it It is used to verify possible physical recording errors in the logical record segment
checksum
A value created by adding up bits in a packet The resultant value is computed at the sender and receiver of data Mismatches will cause error-recovery routines to be followed
checksum
A value calculated from items of data that may be used to verify that the data has not been altered
checksum
A block check character that is formed by taking the sum of the binary data transmitted
checksum
A checksum is a calculation applied to bits in transit before transmission, and then transmitted with the data The receiving device repeats the calculation on the received bits If the result is the same as the received checksum, then it is effectively certain that what is received is exactly the same as what was sent
checksum
A method of detecting errors in a data packet, by summing the value of each byte and transmitting that sum along with the packet The receiver performs the same operations, and if the sum matches, the packet is accepted CRCs are a better method, as checksums are prone to accepting packets which are in fact erroneous
checksum
Cyclic Redundancy Check (CRC), a computed value that is compared with stored data to tell if a file has been corrupted during transfer
checksum
A number computed by glomming together all the characters from an entire file in a special mathematical way If you are afraid that a file is going to change, perhaps getting messed up by being transmitted across noisy lines, you can calculate a checksum before and after transmitting it If you get the same checksum, the file probably did'nt change
checksum
The result of the use of a mathematical equation, used for error checking purposes, on data that is transmitted over a communications link
checksum
Numeric value used to verify the integrity of a block of data The value is computed using a checksum procedure A crypto checksum incorporates secret information in the checksum procedure so that it can't be reproduced by third parties that don't know the secret information
checksum
A numerical value that produces a predetermined constant when added to the sum of a specified group of bytes Used in summation checks
checksum
An additional set of information transferred with a computer program or a data stream that is used to verify the accuracy of the data just transfered
checksum
(n ) The result of adding a group of data items that are used for checking the group The data items can be either numerals or other character strings treated as numerals during the checksum calculation The checksum value verifies that communication between two devices is successful
checksum
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 degree of confidence that the data was received correctly [Source: NNSC]
checksum
An integer value given to each sequence file created with Wisconsin Package editors or programs Programs check this value each time a sequence file is used as input It is a check against the corruption of the sequence data For more information, see Chapter 2, Using Sequences
checksum
A mathematical calculation applied to the contents of a packet or file before and after it is transmitted If the "before" calculation does not match the "after" calculation, there were errors in the transmission
checksum
A checksum is a number used to check the integrity of a file There are numerous methods for calculating a checksum value
checksum
A primitive error-detection scheme where the sender adds the binary values for each data item sent (byte, word, etc ), and then transmits this sum along with the data The receiving end computes the checksum the same way, and then compares it to the value sent If they differ, this indicates that an error occurred during transmission However, if they are the same, it does not guarantee that the data is error-free A more common approach uses CRC to detect a broader range of errors
checksum
Method for checking the integrity of transmitted data A checksum is an integer value computed from a sequence of octets taken through a series of arithmetic operations The value is recomputed at the receiving end and compared for verification
checksum
{i} final check, examination of several of the bits which are transferred in order to discover transfer errors (Computers)
