A Telnet client is called a local host; a Telnet server is called a remote host.
■ Simple Network Management Protocol (SNMP)

A protocol that provides a means to monitor and control network devices and to manage
configurations, statistics collection, performance, and security.

■ Domain Name System (DNS)

A system used on the Internet to translate names of domains and their publicly advertised
network nodes into IP addresses.

2.7.3.2 Transport Layer

The transport layer provides transport services from the source host to the destination host.
It constitutes a logical connection between the network’s endpoints: the sending host and the
receiving host.

Transport protocols, shown in Figure 2-9, segment and reassemble data that upper-layer
applications send, into the same data stream between endpoints.

The transport layer data stream provides end-to-end transport services, sometimes called
end-to-end services.
