An algorithm is simply a process, formula or method for solving a (usually mathematical) problem. On the web, an average user, blogger or website owner is most likely to come across algorithms in relation to search engines, particularly Google. The Google search algorithm is a method of finding the most appropriate search results for a particular search query.

Attenuation

July 9, 2007

Attenuation means the loss of a signal.

So in broadband terms, it refers to the loss of the broadband signal as it makes its way from your exchange to your home. Attenuation can be caused by the distance between you and the exchange, or poor quality cables. Attenuation is measured in decibels (Db).

Always On

July 2, 2007

Broadband services are referred to as “always on” as you don’t have to dial in to activate the service as you do with a narrowband (dial-up) internet access service.

Anti-Virus Software

June 19, 2007

Anti-virus software protects your computer from malicious code such as worms, trojans and viruses – whether in emails, downloads, and websites.

It is essential that a computer has up-to-date virus software running before a user goes onto the internet.

Dynamic IP address

June 16, 2007

A Dynamic IP address is one that changes each time you go online. All computers need an IP address when they connect to the internet, so they can be identified by other computers. Websites need fixed IP addresses. However casual web browsers don’t – so they are often allocated a dynamic IP address by their internet service provider (ISP) which changes each time they go online.

An IP address is made up of four sets of numbers with each set separated by a dot. Each set of numbers is between 0 and 255. With the extraordinary growth in the numbers of people going online around the world, it is easy to see that IP addresses based on number combinations could run out.

So if an internet service provider gives a web user a dynamic IP address, it reduces the need for IP addresses in general as the IP adresses a provider owns can be re-used. The internet service provider also saves money as it only needs enough IP addresses for the number of people likely to be going online at one time, rather than having to ensure that each subscriber has a specific IP address available to them at all times (which is what it would have to do if they gave each subscriber a fixed IP address when they signed up).

IP Address

June 11, 2007

IP stands for Internet Protocol – and the IP address is a unique identifying address given to every computer connected to the internet. It takes the form of four sets of numbers with each set separated by a dot. Each set of numbers is between 0 and 255.

Computers accessing the internet via an ISP may be allocated a temporary IP address by their ISP for that internet visit – however a website will require a fixed IP address. Many broadband providers include a free IP address with some of their broadband packages.

Internet Accelerator

May 8, 2007

An internet accelerator reduces the size of each webpage before it downloads to your pc. This can be useful if you are unable to receive broadband and are stuck on dial up; or if your broadband speeds are two slow for your requirements and you are unable or unwilling to upgrade to a faster package.

Although it can’t change the actual speed of your web connection, an internet accelerator can compress each element of a web page or email using Content Sensitive Compression (‘CSC’) . Once compressed, your web pages and emails can upload and download more quickly.

Unlimited Download Allowance

April 10, 2007

Broadband providers and ISPs often include unlimited downloads with a broadband package. If you and your family download large email attachments, film clips, lots of music and other data, an unlimited download allowance may be of use.

However unlimited downloads won’t be totally unlimited – broadband packages tend to include a fair use policy (sometimes known as an acceptable use policy) which puts (high) limits on how much you can download. Broadband providers say that these policies are needed as a few users are downloading so much data, so often that the broadband service for other users is disrupted.
