Definition: TCP/IP from Dictionary of Information Science and Technology

the set of communications protocols that implement the protocol stack on which the Internet and most commercial networks run. The Transmission Control Protocol (TCP) and the Internet Protocol (IP) were also the first two networking protocols defined. (Shah & Carey, 2009)


Summary Article: TCP/IP
from International Encyclopedia of Hospitality Management

TCP and IP are protocols governing the handling and the formatting of data in an electronic communications system; they are the main protocols used on the Internet. The messages (files) exchanged over the network are divided into small units (called packets) by TCP, while IP takes care of managing the actual delivery of the data. The routing needed to accomplish this is completely transparent to the user. All is needed in order to access another system is an ‘Internet address’ (called IP address), a 32-bit number, normally written as 4 decimal numbers. A specific service, called DNS (domain name service), provides a database containing the correspondence between numeric addresses and alphabetic domain names. TCP/IP uses the client/server model of communication in which a computer user (a client) requests and is provided with a service by another computer (a server). This is the case, for example, in which a consumer is asking to view a hotel website. TCP/IP protocols support services such as remote login to a computer, file transfer (FTP), electronic mail and the World Wide Web. In the hospitality industry, beside these applications, many internal networks are using TCP/IP protocols to connect not only computers, but also other electronic equipment.
