ICT stands for Information & Communication Technology... it is basically a field that focuses on the uses of technology, such as computers, and ways of working that help individuals and organisations use information and be more efficient.
ICT personnel usually refer to group of technology and procedures that serve a particular purpose as a 'system' or 'service', (hence 'ICT Services'). For example, communication services, a learning management system, printing services or a backup system. Each system provides a particular service to users.
All the devices and systems at an organisation can "talk" to each other via cables and switches which send the electrical signals around. This is termed a Local Area Network (LAN). If wireless access is used instead of cables, it can be termed a Wireless LAN (WLAN).
Two or more LANs connected together are termed a Wide Area Network (WAN). For example, our WAN consists of all the Archdiocese of Canberra-Goulburn schools' networks. Now expand that by the number of organisations in a city, times the number of cities in a country, times the number of countries in the world and bam! - you have a world wide web. This collection of inter-connected networks is termed the Internet.
It hasn't taken long for organisations to work out they can make money by charging people to use services on their network. This was the birth of online businesses and, now that we can store a huge amount of files online, cloud computing - that is just a term for using services on someone else's network, because they do it better than we could ourselves, or for free, sometimes, like in the case of Google Apps for Education - an online service.
So that is where we are up to at the College. But, all this interconnection with other people and information poses some problems. There are ethical situations which have never been encountered before, such as the ease of copying music files that we haven't paid for. Cyber-bullying and privacy of your personal information is also an issue... so here are some reminders before you dive in:
