The application layer does not define the application itself, but rather it defines (73) that applications need—like the ability to transfer a file in the case of HTTP. In short, the application layer provides an (74) between software running on a puter and the network itself. The TCP/IP application layer includes a relatively large number of protocols, with HTTP being only one of those. The TCP/IP (75) layer consists of two main protocol options—the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP).(71)A. application B. transport C. link D. network(72)A. hardware B. software C. packet D. equipment(73)A. services B. processes C. applications D. address (74)A. iteration B. object C. interface D. activity (75)A. application B. session C. physical D. transport11 / 11
