Explanation
In networks, a device that filters and forwards packets between LAN
segments. Switches operate at the data link layer (layer 2) and
sometimes the network layer (layer 3) of the OSI Reference Model and
therefore support any packet protocol. LANs that use switches to join
segments are called switched LANs or, in the case of Ethernet
networks, switched Ethernet LANs.
A protocol used for the transmission of event notification messages
across networks, originally developed on the University of California
Berkeley Software Distribution (BSD) TCP/IP system
implementations, and now embedded in many other operating
systems and networked devices. A device generates a messages, a
relay receives and forwards the messages, and a collector (a syslog
server) receives the messages without relaying them.
Syslog uses the user datagram protocol (UDP) as its underlying
transport layer mechanism. The UDP port that has been assigned to
syslog is 514. (RFC3164)
Transmission Control Protocol. TCP, together with IP (Internet
Protocol), is the basic communication language or protocol of the
Internet. Transmission Control Protocol manages the assembling of a
message or file into smaller packets that are transmitted over the
Internet and received by a TCP layer that reassembles the packets into
the original message. Internet Protocol handles the address part of
each packet so that it gets to the right destination.
TCP/IP uses the client/server model of communication in which a
computer user (a client) requests and is provided a service (such as
sending a Web page) by another computer (a server) in the network.
Trivial File Transfer Protocol. An Internet software utility for transferring
files that is simpler to use than the File Transfer Protocol (FTP) but less
capable. It is used where user authentication and directory visibility
are not required. TFTP uses the User Datagram Protocol (UDP) rather
than the Transmission Control Protocol (TCP). TFTP is described
formally in Request for Comments (RFC) 1350.
