IP:
An IP address ( Internet Protocol
address) is a unique number, similar in concept to a
telephone number, used by machines (usually
computers ) to refer to each other when sending
information through the Internet . This allows
machines passing the information onwards on behalf
of the sender to know where to send it next, and for
the machine receiving the information to know that
it is the intended destination. An example of an IP
address is 212.116.XX.XX.
Domain name:
A domain name is the
unique name of a computer on the Internet that
distinguishes it from the other systems on the
network. They are sometimes colloquially (and
incorrectly) referred to by marketers as "web
addresses".
Dial-up access:
Dial-up access is relatively slower
form of internet access in which the client uses a
modem to dial the internet service provider's (ISP)
node, a dialup server type such as the
Point-to-Point Protocol and TCP/IP protocols to
establish a modem-to-modem link, which is then
routed to the internet.
ADSL:
Asymmetric Digital Subscriber Line (ADSL) is a form
of DSL, a data communications technology that
enables faster data transmission over copper
telephone lines than a conventional modem can
provide.
Broadband:
Broadband in general refers to data transmission
where multiple pieces of data are sent
simultaneously to increase the effective rate of
transmission
E-mail:
Electronic mail, abbreviated e-mail
or email, is a method of composing, sending, and
receiving messages over electronic communication
systems.
Web hosting:
Web hosting is a service that
provides Internet users with online systems for
storing information, images, video, or any content
accessible via the web. Web hosts are companies that
provide space on a server they own for use by their
clients as well as providing Internet connectivity,
typically in a data center. Web hosts can also
provide data center space and connectivity to the
Internet for servers they do not own to be located
in their data center.
DNS:
The Domain Name System or
DNS is a system that stores information about
hostnames and domain names in a kind of distributed
database on networks, such as the Internet. Most
importantly, it provides a physical location (IP
address) for each hostname, and lists the mail
exchange servers accepting e-mail for each domain.
LAN:
A local area network (LAN) is a computer network
covering a local area, like a home, office or small
group of buildings such as a college.
When using Ethernet the computers are usually wired
to a hub or to a switch. This constitutes the
physical layer.
Proxy Server:
A proxy server is a computer network
service which allows clients to make indirect
network connections to other network services. A
client connects to the proxy server, then requests a
connection, file, or other resource available on a
different server. The proxy provides the resource,
possibly by connecting to the specified server, or
by serving it from a cache. In some cases, the proxy
may alter the client's request or the server's
response for various purposes.
Intranet:
An intranet is a local area network
(LAN) used internally in an organization to
facilitate communication and access to information
that is sometimes access-restricted. Sometimes the
term refers only to the most visible service, the
internal web site. The same concepts and
technologies of the Internet such as clients and
servers running on the Internet protocol suite are
used to build an intranet. HTTP and other internet
protocols are commonly used as well, especially FTP
and email. There is often an attempt to use internet
technologies to provide new interfaces with
corporate 'legacy' data and information systems.
VPN:
A Virtual Private Network, or VPN, is
a private communications network usually used within
a company, or by several different companies or
organizations, communicating over a public network.
VPN message traffic is carried on public networking
infrastructure (e.g. the Internet) using standard
(often insecure) protocols.
Plug-n-play:
Plug and Play is a term used in the
computer field to describe a computer's ability to
have new devices, normally peripherals, added to it
without having to reconfigure or (ideally) restart
the computer. There are a number of terms or
variations that describe similar abilities,
including PnP, and hot swapping. The term Plug and
Play is most associated with Microsoft, who started
using it in reference to their Windows 95 product.
Many other operating systems had already supported
such features for some time, but all of them soon
used the same terminology
VoIP:
Voice over Internet Protocol (IP) A type of
telephone system that uses the internet to make a
receive telephone voice calls. Its advantages over
traditional telephony include: lower costs per call,
or even free
