A
Access or making
a connection to the Internet. You would normally do
this via an ISP (Internet Service Provider) such as
Mesh, but you may also have access to the Internet
through an office network.
Account When
you sign up for Mesh you are given a username and
password. This is your account and each time you go
online it allows Mesh to check that you are authorised
to access the Internet.
Acrobat Also
known as the Acrobat Reader. This program allows you
to read documents that are stored in the PDF format
(Portable Document Format). There are versions of
Acrobat available for PC, Macintosh and Linux computers,
which means that documents stored as PDF files can
be opened and read by anyone, regardless of what type
of computer they use.
Attachments These
are files that are sent with an email message. They
can be text, graphics, sound, video, spreadsheets,
databases, or even an entire application. However,
attachments can also come in the form of computer
viruses that can damage your computer. Be wary of
attachments and don't open any attachment unless you
know and trust the person that sent it to you.
B
Bandwidth refers
to the amount of data or information that your Internet
connection can cope with. The more bandwidth you have,
the faster you can receive data from the Internet.
A simple text-only email message doesn't need much
bandwidth, but audio and video clips require a lot
of bandwidth.
Banner Also known
as 'banner ad' - an advert in the form of a graphic
image, normally situated right at the top of a web
page.
Baud Rate This
is the technical term for the speed at which you connect
to the Internet via your modem, and is measured in
kbps (kilobits per second). Most modems have a maximum
baud rate of 56kbps - often shortened to just 56k
- but the actual connection speed may be somewhat
lower because of factors such as interference on the
phone lines.
Bookmark Web
browsers allow you to add 'bookmarks' that store the
address of your favourite Internet sites. This allows
you to visit the site whenever you want to, without
having to type in the site's full address each time.
Broadband A high-speed
Internet connection that is much faster than an ordinary
56kbit modem. The Mesh broadband service, Mesh Broadband,
is up to 20 times faster than dial-up with a top speed
of 1Mbps (1 megabit per second).
Browser A web
browser is a program that allows you to enter and
explore the World Wide Web. You are probably using
a browser right now to read these Help files. Internet
Explorer is the most popular browser at present and
comes pre-installed on all PCs and Macintosh computers.
C
Connection Your
computer connects to the Mesh Broadband Network via
the wireless Subscriber Unit (SU) supplied by Mesh
Broadband. This has nothing to do with your telephone
line, so you can be accessing the Internet and be
on the telephone at the same time.
Cookie A cookie
is a small piece of software, usually left by a website
and stored on your computer's hard drive, which records
information about you and your browsing habits on
the Internet. For example, if you are a regular user

allow the shop to remember your name and details of
all your purchases.
Cursor A blinking
line or shape on the screen that tells you where the
next character will go while you are typing.

screen that you can see when no other files or applications
are open. If you are on a computer with the Windows
operating system you should see the My Computer, My
Documents and Recycle Bin icons on your desktop.
Dial-up Most
people connect to the Internet by using their computer
and modem to dial the telephone number of their ISP
(Internet Service Provider) over an ordinary telephone
line. This is known as a 'dial-up connection'.
DNS Domain Name
Server. A system housed on a number of servers on
the Internet that converts domain names to a unique
number known as an IP (Internet Protocol) address.
Domain Name A
domain name on the Internet is rather like the street
name in an ordinary postal address. Each site on the
Internet has its own domain name, such as meshbroadband.co.uk.
Download When
you transfer any document or information from the
Internet onto your own computer, this is known as
a 'download'. See also: Upload
Driver A small

your questions for you.
Firewall A firewall
is a computer program that acts like a barrier, protecting
a company's internal network from unauthorised external
access (most commonly in the form of Internet hackers).
Flame An insulting

information such as the subject of the message and
the email address of the person who sent the message.
Hit Strictly speaking, the term 'hit' specifically
refers to the number of files that you download when
you visit a website. A web page with a picture on
it would count as two hits - one for the page itself
and another for the picture. However, some people
use the word 'hits' less accurately to refer to the
number of people that visit a particular website each
month - for example, 2,000 hits per month.
Home Page All sites on the World Wide Web consist
of a series of 'pages'. The 'home page' is the first
page you see when you visit a website, and acts as
the main entry point that leads to all the other areas
within the site.
HTML Hypertext Markup Language (HTML) is the
computer programming language used to create web pages.
It allows pictures and text to be combined to create
web documents that can be viewed by browsers. Its
most important feature, though, is 'hypertext' - the
ability to create links that take you from one page
to another. See also: Gif, Jpeg, World Wide Web
HTTP This stands for Hypertext Transfer Protocol
- the computer 'language' used to link together all
the HTML pages found on the World Wide Web.
Hyperlink On World Wide Web pages, hyperlinks
are highlighted text or images which, when selected
(usually by clicking the mouse button), follow a link
to another page. Hyperlinks can also be used to automatically
download other files as well as audio and video clips.

is a small picture that computers use to represent
an area, function or an application to provide a visual
target for your cursor to click on. So a picture of
a computer accompanies the functions that apply to
your computer, and can be found above the words 'My
Computer' on the Windows desktop.
Image Map An
image map is an image on a web page that is divided
into a series of 'hot spots'. Each hot spot acts as
a link that will take you to another page with additional
information. For example, the image could be a weather
map that covers a number of cities. Each city on the
map would be a separate hot spot, and clicking on
a city would take you to another page that had a detailed
weather forecast for that area.
Instant Messaging
A form of high-speed chat that lets you instantly
exchange messages with friends or colleagues. Popular
messaging programs include Microsoft's MSN Messenger,
Yahoo Messenger.

by Microsoft and is installed on most PCs.
IP Internet
Protocol (IP) is the main protocol - or computer 'language'
- used to connect computers across the Internet.
IP Address An
IP address is a bit like a telephone number. Every
computer connected to the Internet has an IP address
in the form of a four-number code such as 255.124.165.231.
However, these codes can be difficult to remember,
so each IP address can also be linked to a 'domain
name' that is easier to remember, such as meshbroadband.co.uk.
See also: Domain Name ISDN Integrated Services Digital
Network (ISDN) is a digital telephone line that provides
faster Internet connection speeds than ordinary analogue
lines.
ISDN allows simultaneous
transfer of voice, data and video information, but
it may soon be made obsolete by ADSL and cable modems,
which both provide even faster 'broadband' connections.
ISP An Internet
Service Provider (ISP) is a company or organisation,
such as Mesh Broadband, dedicated to providing home
users and businesses with access to the Internet.
J
Jpeg A Jpeg file
is a way of storing high-quality photographics on

Leased Line A
rented, high-speed Internet connection for private
use, available 24 hours a day. Leased lines can cost
companies (and some very rich individuals) more than
£100,000 a year - the price depends on the amount

Internet using a typical 56k modem. See also: Gigabyte,
Kilobyte
MIME Multipurpose
Internet Mail Extensions - a format designed originally
to include images, sounds, animations and other types
of documents within Internet mail messages.
Mirror site Some
websites are so popular that they can become congested
by all the people trying to download files from the
site - sort of like an online traffic jam. To relieve
this congestion, the owners of the site may create
several 'mirror' sites around the world. The mirror
site contains all the same files as the original site.
If you find a mirror site that is close to you - in
the same country or continent - you will probably
be able to download sites more quickly than using
the main site. See also: Download
Modem Short for
MODulator/DEModulator, a modem is the device that
connects your PC to the telephone network so that
it can communicate with other computers on the Internet.
Modems these days are often built into your PC, but
you can also buy external modems if you have an older
computer that doesn't have one built in. See also:

page contains links that lead you to other pages or
other sites on the Web. Many people think that the
Web is the same as the Internet, but the Web is actually
just one part of the Internet. Email and newsgroups
are other parts of the Internet that are separate
from the Web. See also: Browser, Internet
