GOING ONLINE

The internet is a huge network with computers interconnected all over the world thanks to router and paying for the service. The internet was developed in the 60’s.

Today we can access with web browsers: Mozilla Firefox, Safari, Google Chrome, Internet Explorer.

How to search web

Webpages have hypertext links. These are when you put the cursor on a piece of information, then you click and you can get to other website or play a video, a song, etc.

We can use search engines to look for a specific point of information: Google, Bing, etc. If I need to do a project about wolves for example, it is a good idea to type: wolf, feature, continent; because the research will be more precise.

Blog and video

Blogs are very easy to use and a very fast way of publishing a website. They are used to exchange information: diaries, expand knowledge, describe hobbies.

The two main platforms are blogspot and wordpress, but YouTube and Vimeo are the equivalence with video

Social media

Facebook, Twitter, Snapchat, etc work like a group of friends. To interact with others you will probably need to send invitations. You need to be very careful who you are interacting with.
