Switch – 1. A data switch connects computing devices to host computers,
allowing a large number of devices to share a limited number of ports. 2. A
device for making, breaking, or changing the connections in an electrical
circuit.
TCP (Transmission Control Protocol) – A method (protocol) used along with
the Internet Protocol to send data in the form of message units between
computers over the Internet. While IP takes care of handling the actual
delivery of the data, TCP takes care of keeping track of the individual units of
data (called packet) that a message is divided into for efficient routing through
the Internet.
TCP/IP – Transmission Control Protocol/Internet Protocol (TCP/IP) is the
basic communication language or protocol of the Internet. It can also be used
as a communications protocol is a private network (either an intranet or an
extranet). When you are set up with direct access to the Internet, your
computer is provided with a copy of the TCP/IP program just as every other
computer that you may send messages to or get information from also has a
copy of TCP/IP.
UDP (User Datagram Protocol) – A method (protocol) used along with the IP
(Internet Protocol) to send data in the form of message units (datagram)
between network devices over a LAN or WAN. While IP takes care of handling
the actual delivery of the data (routing), UDP takes care of keeping track of the
individual units of data (called packets) that a message is divided into for
efficient delivery over the network. UDP is known as a "connection-less"
protocol due to NOT requiring the receiver of a packet to return an
acknowledgment of receipt to the sender of the packet (as opposed to TCP).
URL (Uniform Resource Locator) – The address that defines the route to a file
on the Web or any other Internet facility. URLs are typed into the browser to
access Web pages, and URLs are embedded within the pages themselves to
provide the hypertext links to other pages.
