Token
A token is a unique frame that is approved from node to node about a ring system, it is a sequence of bits passed continuously between nodes in a fixed order and enables a node to transmit information. When it gets to a node that requires transmitting data, the node modifies the token into a data frame and transfers it to the receiver. A token is fundamental to the internal workings of a token ring network.
Tokenization
Tokenization is the process of replacing sensitive data with unique identification symbols that retain all the essential information about the data without compromising its security. Tokenization, which seeks to minimize the amount of data a business needs to keep on hand, has become a popular way for small and mid-sized businesses to bolster the security of credit card and e-commerce transactions while minimizing the cost and complexity of compliance with industry standards and government regulations.
