Comments
Identifies a node as a member of a domain.
DS1 (T-1) carries 1.544 Mbps, DS3 (T-3) carries
44.736 Mbps
Computers, Controllers, and other devices that
communicate via networking devices.
10 or 100 Mbps, Baseband network that uses
various media (thick coax, thin coax, twisted pair,
or fiber optic cable).
Example: 10BaseT is 10 Mbps Twisted Pair.
Use for send and receive files between an FTP
client and an FTP Server.
The Switch or Bridge reads the content of a packet
(such as destination address) to determine whether
the message should be blocked or forwarded.
Application software that runs in a computer, or a
dedicated firewall device that includes a dedicated
computer and software. In either case, it is placed
in the data path between networks.
In some cases, the content of firmware is fixed, and
cannot be altered. In other firmware (e.g., Flash),
the content can be re-written.
See "Filtering".
Framing techniques vary with protocols used.
Typically, message data is preceded by an
identifying "header" and is followed by an error-
check sequence.
The name is resident in each Host computer.
The portion of the IP address (right part) that
uniquely identifies a Host device on a network.
Application-Layer protocol that controls
transactions between the web client and the web
server.
Access to the Internet is governed by a world-wide
set of rules. IP (Internet Protocol) addresses are
assigned by Internet Corporation for Assigned
Names and Numbers(ICANN)
