You probably use it every day. L But do you know what the internet is? E Do you know how it works?

L E Y Acquire New Learning Be a Griffin The internet is a world wide network of devices to bring services to users.  www.Cardinalgriffin.staffs.sch.uk P AAcquire New Learning A global collection of I computer networks N Most schools, offices and homes have a network. S These networks join together to form the internet, L which connects over 50 billion devices worldwide. E Y Acquire New Learning Be a Griffin The internet is a world wide network of devices to bring services to users.  www.Cardinalgriffin.staffs.sch.uk P AAcquire New Learning I Cables N The simplest method of joining networks together is using cables. S It isn't practical to run cables between all the schools, offices and homes in a L country, so existing telephone cables are used. E Telephone cabinets contain the cables that connect networks to the internet.

These cables carry very high volumes of data at very high L speed. They are very expensive and very important. E If the cables are damaged, then whole countries can lose Watch this their internet connection. video Y Acquire New Learning Be a Griffin The internet is a world wide network of devices to bring services to users.  www.Cardinalgriffin.staffs.sch.uk P A Activity 4.1: Demo where to locate and how to We Do complete I N S L Lots of Written Practice E Y Acquire New Learning Be a Griffin The internet is a world wide network of devices to bring services to users.  www.Cardinalgriffin.staffs.sch.uk P A Activity 4.1: Submarine cables You Do I N S L Lots of Written Practice E Y Acquire New Learning Be a Griffin The internet is a world wide network of devices to bring services to users.  www.Cardinalgriffin.staffs.sch.uk P AAcquire New Learning Online services I N Connecting computers over the internet means that many services are S available online.

S Cloud computing involves taking things that would be traditionally done on a L computer and hosting them online so that they can be accessed from anywhere. E Y Acquire New Learning Be a Griffin The internet is a world wide network of devices to bring services to users.  www.Cardinalgriffin.staffs.sch.uk P AAcquire New Learning The advantages of cloud I storage Many business backup their files online and many people back up their photos online. N Storing your files and photos online in the cloud has many advantages, including: S you can access your data on more than one device you can access your data anywhere in the world if you have an internet connection L you will not lose your data if your device is lost, stolen or damaged there is, potentially, unlimited storage E you can easily share your data with other people. Y Acquire New Learning Be a Griffin The internet is a world wide network of devices to bring services to users.  www.Cardinalgriffin.staffs.sch.uk P AAcquire New Learning The disadvantages of cloud I storage However, there are disadvantages to storing files and photos online. N You can store only a relatively small amount of data for free. S Monthly fees for extra storage can be expensive. Cyber criminals can potentially L access your files from a cloud server without accessing your computer or phone. They can then ransom them, E delete them or steal sensitive information.

N Using online software has many advantages, including:  you do not need to install software on your computer  you never have to worry about software updates S  you’re less likely to be affected by malware because the data and programs are not stored on your computer  you can work on your files anywhere using any device if you L have an internet connection  you don’t need a powerful computer because the processing is done by the server running in the cloud  some of the most popular online software, including Google E Docs, Google Sheets and Office Online, is free.

N You can only access online software if you’re online. Online image-editing and video-editing software is getting better, but it can be very slow. S Online versions of software often have fewer features than the downloadable versions. The software developer may earn money selling L advertising, so you may be distracted by a lot of adverts. The software company may have access to your work E and could sell this information to someone else.
