A checksum is used solely to see if a file has changed or to see if two files contain exactly the same data. The chances of two different files having the same checksum is very, very small.
If you change a file in any way, even by one byte, the checksum will change.

Why did the Checksum values change with each new request?
Every packet has a new set of error detection assigned to it, the Checksum is a part of this process. The error correction occurs in the transport layer where the ACK will fail and the receiving host will request the packet to be sent again.
The OSPF packet format has a checksum field but the RIP packet does not why?
RIP messages are wrapped in a UDP package, which already has a checksum.
What does it mean when a protocol gets a checksum?
A checksum is used to determine that the information sent using the protocol has not been corrupted en-route.
IP TCP and UDP all discard a packet that arrives with a checksum error and do not?
Only TCP will automatically discard a packet with a bad checksum. UDP packets have a checksum field, but it is rarely used, and then only by the application (not UDP itself)
What would one need a checksum for?
A checksum (also known as a hash sum) is a small size datum computed from a block of digital data. One would use a checksum to detect errors that could have been introduced during storage.
What is 8-bit checksum of 110F3F0D0F?
7b
Write a program in c for checksum?
yes
Which size checksum does md5 produce?
128
Do checksums change during transmission?
If the checksum did change during transmission, wouldn't that mean a transmission error occurred? Any compression or encryption in the middle of transmission affects the data at that moment, but that's the wrong time to try to calculate a checksum for comparison purposes. (Unless it is yet another layer of error checking, used after compression/encryption but before transmission, and again after reception but before decompression/decryption.)
Assume that the data unit 00001111 11110000 excludes the checksum and that it is divided into se Once a checksum checker computes the total for the data unit what will the complement of the result be?
00000000
What is computed checksum?
A checksum is a part of almost any number you want to include self-verification. Some examples are credit card numbers, bank account numbers, computer file "fingerprints," and computer security codes. See related links for a more detailed explaination of ways checksum is calculated.
What is the correct designation for the checksum for the information link in the vehicle?
CKSM
