I previously wrote an article about common terms you will find on the internet, but not that many people know what they mean. So here I am with more useful hints to clarify these terms and with some luck give you a better understanding of them, while not having to pick up the telephone and asking your buddy who also doubles as your IT support guy.

Broadband

This is a term utilised for any always-on web connection that isn't dial-up. This typically applies to most new Internet connections these days (I hope you're not depending on dial-up). They can be through your standard copper telephone lines or shiny new fibre optic lines. Of course in other countries such as New Zealand you may also get broadband though satellite. 3G and eventually 4G mobile networks may be able to provide decent connection speeds too , though they aren't considered broadband.

Firewall

No, it's not a literal wall of fire; though that would prevent people from physically taking info that they aren't authorised to use. A firewall is a device that looks a lot like your router or switch that controls what connections come in to your network. This is a way of stopping folk from prowling onto your network and having an inquisitive look through your files and other personal information. If you're a home user you can deploy a software firewall, though this is not as good as a physical firewall.

Plugin

A straightforward way to clarify this: add-on. Something similar to your web browser can be boosted by getting a plugin. For example: it's possible to get a plug-in that will allow you to talk to your pals on Facebook or have your iTunes library info scrolling along the bottom of your browser. Add ons can be made for plenty of other programs too,eg Microsoft Office or Adobe Photoshop. Just remember that malicious programs can on occasions masquerade as a plugin to get you to click them, so if it's not on a trustworthy site, don't download it.

I certainly hope that this helps. Happy computing!
