An Internet service provider (ISP), also sometimes referred to as an
Internet access provider (IAP), is a company that offers its customers
access to the Internet

An organization offering and providing Internet access to the public
using computer servers connected directly to the Internet.

ISPs offer businesses and consumers connections to the Internet.
Some offer Web hosting and site development services as well.

(In my own words)

An Internet service provider (ISP) is a company that allows customers
access to the internet at a price. Some popular ones are
, sky
broadband, and virgin media.

paying subscribers.

(In my own words)

A web hosting service is a company that allows companies and
individuals to get their websites onto the web and keep them there.
Websites require maintenance and upkeep, this is all performed by the
web hosting service then the company or the individual pays them

A domain structure is a cluster of computers which maintains it's own security and
accounts management locally, i.e.
on the primary domain controller. All logins for local
accounts are done within the domain, and it has its own file and application servers for
locally logged on users. It is generally part of a much larger corporate forest, consisting
of other domains that may or may not "trust" each other, depending upon how they are
set up...there could be an accounting domain, a database domain, a support for goods
and services domain, and an administrative domain in a very large corporation, along
with a client domain (say, the internet website for customers and public users) and even
a client domain for data programmers/software engineers.

In the computer world a domain is a logical way to group computers together. There are
2 main ways to share resources on a network: the workgroup way, and the domain way.
In a workgroup, every computer is king of it's own resources and decides what it going
to be shared and with whom. In a domain, the information is centrally controlled;
members of the domain obey a central authority, usually a server. The server decides
everything and carries all the user names, passwords and access each user has.

(In my own words)

Domain structure is the build up of a group of computers. E.g. at work in an office or at
school there’s a local drive and a shared drive. The local one is yours and yours alone.
The shared drive is open to viewing and possibly editing from the other computers in
the domain.

Companies accredited by ICANN (The Internet Corporation for
Assigned Names and Numbers) that offers registration services for the
domain names of organizations and individuals.

domain names

An organization that manages Internet domain names. Any person or
company that wants a presence on the Internet must register a unique
name with one of the more than thousand registrars around the world.

(In my own words)

A domain name registrar is a company that sells the rights of domain
names over to people. This is needed to start a website with a good
catchy domain name. Anyone can buy them, individuals or companies.


World Wide Web

(abbreviated as



W3 commonly known as

the Web), is a

Internet. With a

web browser, one can view


that may contain text, images, videos, and other multimedia, and


between them

hyperlinks. (

It's basically a lot of different files (all over the world) that are linked to each other, so that you can
look at a file that has a link to another file and then follow that link to read the next file. (These days,
it's not just files but useful programs, too.)


A widely used information system on the Internet that provides facilities for documents to be
connected to other documents by hypertext links, enabling the user to search for information by
moving from one document to another


(In my own words)

The World Wide Web is a crosslink of different files and sites from everywhere in the world where you
can go from one to another by simply clicking on a hyperlink. It is the biggest information base on the
planet and is constantly being upgraded and added to.

Web servers

A web server is a computer program that delivers (serves) content,
such as web pages, using the Hypertext Transfer Protocol (HTTP), over
the World Wide Web. The term web server can also refer to the
computer or virtual machine running the program.

A computer that is responsible for accepting HTTP requests from
clients, which are known as Web browsers, and serving them HTTP
responses along with optional data contents, which usually are Web
pages such as HTML documents and linked objects (images, etc.).

Web servers are computers on the Internet that host websites, serving
pages to viewers upon request.


A web server is a computer that hosts a website and allows people to
view it in browser.

Mail servers

An Internet
connected computer set up to receive e
mail from another
server and distribute it to users, and to send e
mail from those users to
another server.

(Mail Server) A server (computer) responsible for sending, routing and
delivering email.

(mail server) A computer on a network whose job it is to receive and
store incoming mail and route outgoing mail to the proper e
mail boxes
on other mail servers.


Mail servers are computers that are set up for the sole use of receiving
and sending emails from or to other servers for its clients (the public).

Proxy servers

A program that deals with external servers on behalf of internal clients.
Proxy clients talk to proxy servers, which relay approved client requests
to real servers, and relay answers back to clients

An intermediate device that receives SIP requests from a client and
then initiates requests on the client's behalf.

A proxy server is a process that acts like a switchboard through a
firewall to manage the various types of permitted communications with
the outside world. Proxy servers may also use caching to make
communications more efficient.


Proxy servers are devices that allow you to put down restrictions on
what you can search and also allow you to bypass firewall restrictions.
They take your HTTP request and do it for you (in browser).


A router is an electronic device that interconnects two or more
computer networks, and selectively interchanges packets of data
between them.

A router is a computer networking device that forwards data packets
across one or more networks toward their destinations, through a
process known as routing. Routing occurs at layer 3 (the Network layer
e.g. IP) of the OSI seven
layer model.

Routers forward data packets across computer networks. A Router
checks the data packet for its destination address and protocol format
details. If the router finds a match in its address tables, it routes it to
that destination address.


A router is an electronic device that allows computer networks to link to
each other and send data between each other.


A program used to view HTML documents

A web browser is a software application for retrieving, presenting, and traversing
information resources on the World Wide Web. An information resource is identified by
a Uniform Resource Identifier (URI) and may be a web page, image, video, or other

Electronic mail, commonly called email or e
mail, is a method of
exchanging digital messages across the Internet or other computer

mail is a way that a computer user connected to the Internet can
communicate with other connected users through text. E

text and attachments to each other


Web protocol is the way that your browser will work.
It can block certain websites due to multiple reasons
and set up guidelines for almost anything you can
use the internet for. Throughout the application layer
there are multiple protocols ranging from ATP’s
(AppleTalk transaction protocols) through to UDP’s
(user datagram protocols). Each protocol makes a
program run differently or changes the order in which
it works. The application layer is the layer that is in
control of the computers linking to each other
(through IP) an the protocols behind it include
Support services, Electronic mail, File transfer, and
Remote logins. These different categories hold
differing protocols that change the way that
computers connect to each other.

Web 2.0

This term refers to the “second generation” of services that are available on the World
Wide Web. Web 2.0 applications include blogs, podcasts,

Web 2.0 is the new web. No longer is it just an anonymous data storage, it is now a
cross linked mess of blogs, documents, opinions and ideas. Social networking and
wikis have completely changed the use of the net.

form of an online journal while readers may comment on posts. Most blogs are written
in a slightly informal tone (personal journals, news, businesses, etc.

Dynamic website maintained by an individual or an organization to provide

Cloud Computing

Cloud computing is Internet
based computing, whereby shared resources, software,
and information are provided to computers and other devices on demand, like the
electricity grid.

Allows software, data and services to reside in data centres that are accessed over the
Internet from any connected device.

internet based computing that enables users to access and share information (be that
documents, video, software, etc) from any computer, anywhere in the world.


Cloud computing is the future of storage. No longer do you need an internal or external
memory storage unit, you can just use cloud. It is a large storage facility off site from
your tower, laptop or device and you can access it from anywhere using the internet. If
you save a word document on your laptop on the way to work on the train for a
presentation the next day you can auto save it to cloud and it will automatically appear
on the storage on all of your synced devices or computers.
