“What is…” 

An app? 

On a computer you have programs such as Word, Excel, email, etc. On an iPhone or iPad, you have Google, email, Weather etc. These are applications (apps for short). 


When you are listening to a radio station, watching a TV show, or watching YouTube you are streaming, not saving to your computer or device.


Downloading is different from streaming. Downloading is when you save a file, a movie, documents, or other data to your computer instead of just watching or listening.


When you upload a file or other data, you are copying or moving it from your computer’s hard drive, or from a device, to a space on the internet. It may be saved to a website to be shared with friends, the world, etc. or just for your own benefit so as not to use up your internal computer space. 


Cookies are small pieces of information generated when you visit websites. Websites (Amazon, for example) use cookies to save your preferences, passwords, etc. in order to steer your next visit towards a purchase of an item that you may have previously searched for. Your antivirus program may catch a cookie that is not from a safe site. In this case you should delete cookies and website history. 


Hyperlink examples: an email address which contains ‘@’ or a website which starts with ‘www’. Clicking on a hyperlink will take you to a website or prepare an email to be sent.


Twitter is a free social networking site to write ‘tweets’ – short notes.

People use the hashtag symbol (#) before a keyword or phrase in a tweet to categorize those tweets and help them show more easily in a Twitter search. Clicking or tapping on a hashtagged word in any message shows you tweets that include that subject. 


A blog is an online journal. A blogger tells a story, with or without pictures, similar to a diary, in order of dates past to present.
