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.

Which size checksum does md5 produce?
128
What is an adjective for compute?
It is computed, as in "the computed value".
How do you calculate checksum value for a message?
To calculate a checksum value for a message, first, divide the message into fixed-size blocks (often bytes). Then, sum the binary values of these blocks together, and if there's an overflow, wrap around and add it back to the sum. Finally, the checksum is typically obtained by taking the bitwise complement of the final sum. This checksum can then be appended to the message for error-checking purposes.
What is invalid checksum?
An invalid checksum indicates that the data integrity check has failed, meaning the data may have been altered or corrupted during transmission or storage. Checksums are numerical values generated from a set of data, and they are used to verify that the data remains unchanged. If the calculated checksum of received data does not match the expected checksum, it suggests an error, prompting a retransmission or further investigation.
How is your credit score computed?
Credit scores are personal information. If you can tell me how your credit score is computed then I will tell you how my credit score is computed. Okay?
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.
How do you calculate the checksum of ICMP packet?
To calculate the checksum of an ICMP packet, you first need to create a pseudo-header that includes the source and destination IP addresses, the protocol number (1 for ICMP), and the length of the ICMP packet. Then, concatenate this pseudo-header with the ICMP packet data. The checksum is computed by performing a bitwise one's complement sum of all 16-bit words in the combined data, followed by taking the one's complement of the final sum. Finally, the calculated checksum is inserted into the ICMP packet's checksum field.
How do you change checksum?
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.
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 is the process for generating a 16-bit checksum for data verification?
To generate a 16-bit checksum for data verification, the process involves dividing the data into 16-bit blocks, adding up all the blocks, and then taking the one's complement of the sum to obtain the checksum. This checksum can be appended to the data for verification purposes.
What is 8-bit checksum of EOOOAO3031?
To calculate the 8-bit checksum of the string "EOOOAO3031," you first convert each character to its ASCII value, sum those values, and then take the result modulo 256. The final checksum is the least significant 8 bits of that sum. For the string provided, the checksum would be 154.
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 is 8-bit checksum of 110F3F0D0F?

What is an adjective for compute?
