for users, which may represent data using different syntaxes. At which of the following layers would you find
such service?

A.
Session

B.
Transport

C.
Presentation

works as a translator, translating the format an application is using to a standard format used for passing
messages over a network.
Incorrect Answers:

application processes, i.e., a semi-permanent dialogue. Communication sessions consist of requests and
responses that occur between applications.

as connection-oriented data stream support, reliability, flow control, and multiplexing.
