hi friends, i want to know how to calculate chechsum value.
Hi Shreyas
Checksum is one of the error detection techniques used in digital communication. It is the one's complimemt of the sum of two or more words/bytes. For example:
If you need to generate a checksum for two bytes, say 11001010 and 01010101, then you need to perform binary addition on them i.e.
11001010
+
01010101
=
00011111, now taking its one's compliment (or simply inverting the bits) we get: 11100000. This result is the required checksum.
