checksum
校验和
Packets may contain encoded information, e.g., a cyclic redundancy check (CRC) and/or a checksum, which is used to determine the integrity of the packet. From herein, the term checksum is used in a general sense to refer to any kind of error check. The checksum may protect the integrity of data by being used to detect errors in data that is sent through space (e.g., over a communication link) or time (e.g., storage). A checksum may be calculated by simply adding up the components of a message or a portion of a message. For example, a header checksum may be based on the information contained in a packet header. A checksum may also be based on a body of a packet containing a message or a portion of the message. Checksums may be an integer number of bits or bytes. A checksum may also be based on a cryptographic hash function.
校验和是用来验证数据从源主机到目的主机的一致性的。在TCP/IP协议族中用到的都是16位的校验和，各部分的校验和有着自己的意义。在现有技术中，确定16位校验和的基本算法包括以下步骤：a.把所有要用来确定校验和的数据分成16位为一组的N个段，若字节数不是偶数，则增加一个字节的全0填充，此填充只是为了确定校验和，确定完毕就将其丟弃；b.对这N个数据段求和，得出一个可能大于16位的和值；c把大于16位的进位值按上面的规则与低16位进行相加，如果又产生了进位，则再加一次；d.把得到的这个值按位取反，就得到的校验和的值。

checksum
检验［校验］和；［核对和］
In data processing and data communications, the sum of a group of data items associated with the group for checking purposes. The data items are either numerals or other character strings regarded as numerals during the process of calculating the checksum.
在数据处理和数据通信领域中，用于校验目的的一组数据项的和。这些数据项可以是数字或在计算检验和过程中看作数字的其它字符串。

checksum
校验和
A calculated value that is used to test data for the presence of errors that can occur when data is transmitted or when it is written to disk. The checksum is calculated for a given chunk of data by sequentially combining all the bytes of data with a series of arithmetic or logical operations. After the data is transmitted or stored, a new checksum is calculated in the same way using the (possibly faulty) transmitted or stored data. If the two checksums do not match, an error has occurred, and the data should be transmitted or stored again. Checksums cannot detect all errors, and they cannot be used to correct erroneous data.
