Parts of the internet

In the following slides, you learn about the various parts of the internet.

Throughout the year, we will constantly use these words so that you can apply them in a discussion.

This is the key to being able, in the future, to work and collaborate online.

Key words:

Surfing = when you are online, going from web page to webpage, you are surfing.

Webbrowser = This is the program you need to get access to the internet.

Website = a collection of webpages with data, like text, images, videos, which are saved (technical term = 'hosted'). Next, the website has been placed on one or more web servers, and (usually) made available through the internet.

The part of the word 'web' in 'website' refers to the worldwide web and the English word 'site' means its place.

Tabs

In the past, you needed a new webbrowser window for each website.

Now, that's no longer necessary.

You can have multiple windows open in one browser window. 

We call these tab pages (tabs).

hotkeys:

Close a tab: ctrl+ w

Open a tab: Ctrl + t

Switch between tabs 

ctrl + pg up or pg down

Task: Try them!

Address bar

The spot where you see the internet address. 

This is where you type the name of the website when you want to surf.

URL

To reach a website you type the internet address.

This internet address we call a URL (uniform resource locator).

Using this, we can find a very specific website or file online.

Onderdelen van een URL

Dissect the URL:
https://www.marnixcollege.nl/internationalisering

Give an example of a domain extension.

Surfing to a website without errors

People often find that the internet knows everything for them. However, when you type in insufficient information, sometimes it leads to errors.

When you don't use a domain extension in your URL, you will always get to a website through a search engine.

In this case, the search engine sometimes gives you the wrong websites. So be specific and precise in your URL use.

Ip-address

Each computer that is connected to the internet has a unique number, the IP-address. Through the IP-address, computers can identify each other, and communicate with each other. Think of it as a type of telephone number for computers.

Websites sometimes also use the IP-address, for example to determine where your location is. The internet provider provides the IP-address.

The IP-address is made up of 4 series of numbers separated by a dot (.). 

When you want to know your IP-address, go to: watismijnipadres.nl

What is the ip-address you are surfing on now?
And what other information did you get when you checked?

A Website also has an IP-address 

Normally, we don't see this as it gets translated into a domain name: the website name.

You can use the following website for this:

https://smartranking.nl/tools/website-ip-checker/

What is the ip-address of marnixcollege.nl?

Now that you know the basics, start working on the 'hidden side' of a website.

A website is built up out of a lot of codes:
html, java, CC+ and many others.

Task:

Use the hotkey combination Ctrl+u.

When you do this, you see the way that the website of Lessonup is built.

You can do this for each page, to find out which code has been used. 

A website consists of different parts:

Preparatory task: 

1. Go to OneNote

2. Do the task. 

3. Make sure that everything is ready for next week.

Didn't you get it? Read the task one more time, check with a class mate and then ask me.
