Applications – often called “apps” – are pieces of software that you can download to run on the internet, computers, mobiles and other electronic devices.

Built by software developers, apps tend to fall into two categories: Useful apps (eg a weather app that can determine your location and provide you with the weather forecast) and fun apps (eg a game you can play on your mobile).
According to Futuresource Consulting, 3.6 billion mobile apps were downloaded from app stores in 2009 and this is expected to rise to 6.6 billion in 2010
Apps can be downloaded from various online app stores, which are owned either by the mobile handset manufacturers (eg Apple App Store and Nokia Ovi Store), mobile network providers (eg Orange Application Shop and Vodafone App Store) or aggregators, such as Handango.
They can vary in price – some downloads might be free whereas others must be paid for.
Because so many applications are now available, they’re often categorised within the stores, into areas such as Entertainment, Games, Music, Shopping, Social Networking, Sport and Travel. Cost varies across apps, with some free and others costing between 29p and £10.
Payment methods differ between app stores and may include credit/debit cards, PayPal accounts and iTunes accounts.
There are additional costs if an app is connected rather than standalone (in other words, if it requires data traffic to be generated in order to function). An example of this is a news app that regularly fetches the latest news from the internet and sends it to your mobile – while the app is running, you will be charged by your mobile provider based on your data package agreement with them.
More and more apps are being developed for families. As well as apps for parents, there are apps to help children read, write, play, create and manage their schoolwork. For example:
What you need to know to get started
Technology is part of your child's life before they start primary school. They're probably using the computer, the internet and interactive TV for fun - watching programmes on the CBeebies channel and website or taking part in the Club Penguin chat rooms...but they still need adult guidance and supervision.
If you have 8-11 year old children, your house is probably full of technology - PlayStation, Nintendo, iPod...the list goes on. In fact, research shows that 8-11 year olds in the UK have an average of four media devices in their bedroom.
This is a crucial age for young people to embrace new technologies and develop their ICT skills both at home and at school...and it's a crucial time for you to take control when they start exploring the digital world as well as the real world.
They're at secondary school and growing up fast. It's a time of change and their digital world might seem as important as the real world to them. They might spend their evenings on Bebo, Facebook or MySpace ; watching videos on YouTube and uploading their own for others to watch; or doing research for their homework.
You want to encourage their technology and social skills, of course, so it's useful to understand what they're doing with technology and to get involved with it.
Once your children are teenagers, it might be tempting to think that they're tech-savvy and dealing with everything the virtual world can throw at them. You probably watch in awe as they switch from chatting with friends on Facebook to updating their Twitter profile; playing against someone on the other side of the world on their games console to downloading music on their mobile.
It's all great fun but, as they get older, the things you need to help them to cope with in their digital world are ever more challenging. Far from leaving them to it, you really need to keep communicating with them.
