If just 1 byte of data has been altered the same process will generate a different string If a checksum has changed unexpectedly then you know there is an inconsistency between copies If the checksums match the data has not altered brPage 4br UK DAT. Maxino Member IEEE and Philip J Koopman Senior Member IEEE Abstract Embedded control networks commonly use checksums to detect data transmission errors However design decisions about which checksum to use are difficult because of a lack of informat This paper examines the behavior of checksums and CRCs over real data from various UNIX 64257le systems We show that when given real data in small to modest pieces eg 48 bytes all the checksum algorithms have skewed distributions In one dramatic cas Electrical systems and board layout are prone to Elec tromagnetic Interference EMI because any alternating current in a conductor generates a prop agating electromagnetic field This field can induc e currents in nearby electrical components and caus LUFKVWUDVVH57347573645736957359573475736057370573705737157368573685735957347FKHUQ5735957347HUPDQ 7HO57373573475735857367573725734757370573715736757364573475736957371573675736957368573665736357347573475734757347573475734757347D Last Updated July 2012 The actual checksum math is easy and from a perfor mance standpoint so cheap that it can be con sidered free In the process of improving the use of hardware checksum of64258oading engines recalculating the IP checksum has been found to be essentialy Definition.
