S is for...Storage, Safari, Search Engine, SEO, Server, Sexting and Skype

Storage: In computer terms, storage tends to refer to a devices capability to store information for the 'long term' (often characterised by data that is kept even when a device is tuned off. This is often based on some form of disk. 'Memory' usually refers to RAM (Random Access Memory - based on one or more chips) which is where a device stores data that it is currently using. It is faster for a computer to retrieve data from RAM than it is from disc, therefore, the larger the RAM the more information a computer can have close at hand, helping it to process the information faster.

Safari: One of the ‘big four’ web browsers, Safari is Apple’s native browser. It is included as standard on Macs, iPhones and iPads.

Search Engine: Google, Yahoo!, Bing – these are all search engines, and their purpose is to find the information you want. By typing a keyword or phrase into the search box, the search engine will trawl the Web looking for the most relevant information. It doesn’t always get it right; but you do get LOTS of options. You can now drag images into the search box and find similar pictures.

SEO: This stands for ‘search engine optimisation’, and is a technique for making webpage content more attractive to search engines. Keywords are important for this, but today it’s more important for content to be useful, relevant and interesting or nobody will be able to find it. Or, indeed, want to read it.

Server: A server is a physical or virtual computer who's role is to 'serve' data to other computers on a network on request. There are many types of server. A Web server will respond to requests with Web pages. A 'File Server', most often found on an internal network will store and deliver documents on request.

Sexting: Sexting is the act of sending sexually explicit messages and/or photos between mobile phones. It's becoming increasingly common among teenagers, who often don't think about where their supposedly private messages can end up...

Skype: Skype is a software application that allows users to make voice calls over the internet. Calls to other Skype users are free, and there is also an instant messaging service. It's great for talking to people in foreign countries if you're a little strapped for cash! Skype also has the ability to make phone calls to and receive calls from a standard telephone system. Skype is one of many examples of a system delivering VoIP (Voice over IP - IP being the 'Internet Protocol', the way in which data is packaged up into small chunks for distributing over the Internet).
