Web 2.0

October 13, 2007

Web 2.0 commonly refers to the second generation of web development and usage.

Rather than the web being simply a tool to provide information to the user, or to sell products and services online, Web 2.0 uses the web as a collaborative and participatory tool in itself.

The growth in social networking sites such as Facebook, Bebo and MySpace; the explosion of user-generated (and user-managed) websites such as Wikipedia; and the upsurge in niche and vertical sites rather than broad content sites; are all part of Web 2.0.

3G

July 20, 2007

3G stands for third generation and usually (though not always) refers to the third generation of wireless personal communications devices (such as mobile phones, and PDAs) and service.

3G offers faster web browsing and mobile video. Higher bandwidth means that the broadband element can still be always on (downloading email, web surfing, games, instant messaging etc), while voice calls take place. Download speeds can be up to 2Mb for static locations and up to 384kb for mobile.

In the UK, licences for the spectrum assigned to 3G were auctioned off to mobile phone network providers at great cost. Setting up the networks required was also extremely expensive for the licence bid winners.

Pop3

July 18, 2007

POP3, or Post Office Protocol version 3, is a standard for retrieving email from a message mailbox on an email server, to your computer. Because the email message actually downloads to your machine you don’t need to stay online to read the message – making it particularly useful to people with dial up connections. Many ISP email accounts (ie not web mail) use Pop3.

If you have a Pop3 email account and you own a domain name you can have an email address such as yourname@yourdomain.com

Mp3- MPEG 1 Audio Layer 3

July 5, 2007

Mp3 stands for MPEG 1 Audio Layer 3, a technology with which audio files are digitally compressed to reduce them to a fraction of their original size – making them small enough to be easily downloadable with a broadband service.

A feature of Mp3 is that sound quality is not affected by compression and the technology is therefore particularly useful for music files.

21CN – 21st Century Network

June 29, 2007

21CN, or the 21st Century Network, is BT’s next generation network. An IP (internet protocol) network, it will offer communications from anywhere to any device, and will deliver a range of converged services including voice, data, mobile TV, and video.

At present, the BT network runs on a Public Switched Telephone Network (PSTN) – 21CN will see it move to an Internet Protocol (IP) network. PSTN is expensive to maintain – 21CN will bring together several systems and the new approach should be both more cost-effective, and ensure that next generation converged services are fast and efficient. The programme is expected to cost £10 billion, with savings of £1 billion a year expected.

On the 21CN network your calls from your home or business will still travel along copper wires to your exchange, as they do now – but at the exchange they will move onto the new IP system along with data traffic.

BT has already run a 21CN trial, linking BT exchanges in central London, Woolwich and Cambridge, carrying over 160 million calls. BT is now migrating live customers – 350,000 customers in Cardiff and the surrounding area are expected to be migrated onto the new IP network by the end of 2007.

ADSL2+

April 3, 2007

ADSL2+ is next-generation ADSL with increased bandwidth – allowing theoretical download speeds of up to 22 or 24 Mb.

Providers include UK Online and Be – both of these companies have been rolling out their LLU (local loop unbundled) networks across parts of the UK. Coverage is now much improved.

Most domestic users are unlikely to need such fast download speeds at this time, and even those who can sign up for an ADSL2+ broadband package will have to be near to the exchange to get really high speeds.

However for businesses ADSL2+ could make quite a difference to download speeds on their networks. Additionally, ADSL2+ has some dignostic capabilities. ADSL2+ may well come into its own for residential broadband customers as IPTV, or Internet Protocol TV, becomes more widely available. (IPTV allows users to watch films and programmes on demand from thousands available). The extra speed available with ADSL2+ may make it much more attractive, especially as many people will also be using their broadband connection for VoIP, internet gaming, and more.
