Does CRC add any overhead to the transmitted data? Yes, CRC adds a certain amount of overhead to the transmitted data. The CRC checksum, which is typically a fixed number of bits, needs to be appended to the original data before transmission. This increases the total size of the data be...
Assume that g(x) is CRC-4, which equals X4+ X + 1, and the source data M is 10110011. In this case, the divisor P is 10011. The transmit end shifts M leftward by four bits, and divides the resulting number by P. Example of CRC calculation at the transmit end ...
CRC is ahashfunction based on binary division. A sequence of redundant bits (called CRC bits) are appended to the end of the data block so that the resulting block is exactly divisible by a second, predetermined binary number. At the receiver's end, the incoming message is divided by this...

文章146 What is a CRC? A CRC (cyclic redundancy check) is a type of function that performs a mathematical calculation on a block of data and returns a number that represents the content and organization of that data. The CRC returns a number that uniquely identifies the data. CRC is the...

Customer retention cost (CRC) refers to the total cost of retaining a customer. It includes the cost of marketing, sales and customer service. The formula for average customer retention cost per customer is: Average customer retention cost per customer = Total cost of customer retention/number of...
The MTU is the sum of the IP packet length and Ethernet header length, that is, MTU = IP MTU + 14 bytes. For example, on some Cisco devices, the MTU is the sum of the IP MTU and Ethernet header. The MTU is the sum of the IP packet length, Ethernet header length, andCRClength...
An IP address is a 32-bit binary number. Because the address 0.0.0.0 indicates an invalid, unknown, or unavailable target, there are (232 –1) addresses except this address. For ease of use, the 32-bit binary number is divided into octets. Each octet is represented in dotted decimal not...
