 | Algorithms can be implemented by computer programs, although often in restricted forms; an error in the design of an algorithm for solving a problem can lead to failures in the implementing program. |
| Algorithms are essential to the way computers process information, because a computer program is essentially an algorithm that tells the computer what specific steps to perform (in what specific order) in order to carry out a specified task, such as calculating employees’ paychecks or printing students’ report cards. |
| Algorithms are not only implemented as computer programs, but often also by other means, such as in a biological neural network (for example, the human brain implementing arithmetic or an insect relocating food), or in electric circuits or in a mechanical device. |

| Checksum algorithms (CRC*, BSD, and SYSV sum) can't be trusted to provide the level of assurance that hash functions are accorded. |
| In fact, checksum algorithms shouldn't be trusted for forensics purposes at all. |
| Checksum algorithms are designed to detect errors in data being transmitted or stored, but are not designed to protect data from being altered by a persistent and/or malicious attacker. |
