The world's largest social network site that lets you share messages, photos and videos with others.
An application that lets you make video calls from your Apple device such as your iPhone, iPad or Mac computer.
A document or program stored on your computer. Each file has a unique name.
The process of your computer reducing some of the non-essential information associated with your files. This means the files don't take up as much memory or storage space on your device.
Every file created on a computer or device has a unique name followed by a short three-or-four character code at the end, separated by a full stop. For example, "mydiary.doc". The code after the full stop indicates what kind of information the file contains and what type of software can view or open it. In our example, "mydiary.doc", the ".doc" tells us it is most likely a Microsoft Word file. Other common file types include ".jpg" (pronounced jaypeg) for photos, or ".xls" for Microsoft Excel spreadsheets.
Software or hardware that protects your computer from hackers or viruses.
An outdated application that plays audio and visual files and types of animation.
