In technology, phrases become obsolete very quickly. And if you're not in the know when it comes to the new cool slang then you could end up looking past it. It may even hamper your job prospects.

For example, in an interview, you should be talking about 'cloud computing', not 'ASPs' even though they are basically the same thing. We've put together the 12 words that should definitely not be using in technology today.

1. Intranet

Popular in the mid-90s, the term 'intranet' referred to a private network running the Internet Protocol and other internet standards such as the Hypertext Transfer Protocol (HTTP).

It was also used to describe an internal website that was hosted behind a firewall and was accessible only to employees. Today, every private network runs IP. So you can just use the term virtual private network or VPN to describe a private IP-based network.

2. Extranet

An 'extranet' referred to private network connections based on internet standards such as IP and HTTP that extended outside an organisation, such as between business partners.

Extranets often replaced point-to-point electronic data interchange (EDI) connections that used standards such as X12. Today, companies provide suppliers, resellers and other members of their supply chain with access to their VPNs.

3. Web surfing

When is the last time you heard someone talk about surfing the web? You know the term is out of date when your kids don't know what it means.

To teens and tweens, the internet and the web are one and the same thing. So it's better to use the term 'browsing' the web if you want to be understood. Or you can just say 'Google' since everyone uses that term as a verb.

4. Push technology

The debate over the merits of 'push' versus 'pull' technology came to a head in 1996 with the release of the PointCast Network, a web service that sent a steady stream of news to subscribers.

However, PointCast and other push technology services required too much network bandwidth. Eventually, push technology evolved into RSS feeds, which remain the preferred method for publishing information to subscribers of the internet. RSS stands for Really Simple Syndication.

5. Application Service Provider (ASP)

During this decade, the term 'Application Service Provider' evolved into 'Software-as-a-Service'. Both terms refer to a vendor hosting a software application and providing access to it over the web.

Customers buy the software on a subscription basis, rather than having to own and operate it themselves. ASP was a hot term prior to the dot-com bust. Then it was replaced by 'SaaS'. Now it's cool to talk about 'cloud computing'.
