SMB

SMTP

Telnet



What are two characteristics of clients in data networks? (Choose two.)

use daemons
initiate data exchanges
are repositories of data
may upload data to servers

What is the role of the OSI application layer?

provides segmentation of data
provides encryption and conversion of data
provides the interface between the applications on either end of the network
provides control of all the data flowing between the source and destination devices
