DEVICES To access the internet you need a device with an internet connection. Compare it with a book, you need this book to access the story inside of it. To access the information on the internet you need a device to get there. Instead of having one book with one story in it, you have multiple devices to access the story on the internet. There are four devices to use; the smartphone, tablet, laptop and PC.

THE PC
The PC (personal computer) is the oldest device to access the internet. The PC consist out of; a screen, that displays your information. A mouse, this is your navigator on the screen. A keyboard, that makes it possible to type and control your PC. And last but not least; the computer. This can be seen as the heart of the whole PC. It contains the on and off button, different ports, and CD-rom drive.
LAPTOP
The laptop is a portable version of the PC. It is easy to transport because all the components are gathered inside one machine. Same as the PC it has a screen and a keyboard. Instead of a loose mouse it has a touchpad; a specialized surface that can translate the motion and position of a user’s fingers to a relative position on the operating system that is made output to the screen. And the heart of the laptop is inside it, just as humans. 7
TABLET
The tablet is a mobile computer with a touchscreen display. The touchscreen display uses gestures by finger to replace the mouse, trackpad and keyboard used in laptops. Most tablets also have sensors, digital cameras and a microphone. It is often used for recreational purposes, rather than professional use.
SMARTPHONE
The smartphone is a mobile phone, but it has way more purposes than just calling and texting. It also has a internet connection, which makes it possible to browse on the internet. Smartphones vary in size and composition. The display is almost always a touchscreen, fingerprint recognition and sometimes additionally a keyboard.

THE INTERNET Now we have learned what kind of devices we need to get entrance to the mysterious world of the internet, it is time to explain what the internet excactly is. The internet is like a big supersmart robot, that can do a lot of tasks at the same time. All the devices are connected to this robot, but this connection is not visible or sensible. Luckily though, because otherwise we could not go outside without tripping over countless amount of cables. You couldn’t fly an airplane through the sky without getting tangled up. So, lets say that all our devices have a voice. A secret voice, that we humans can not hear. They all speak to eachother in the same language that we call ‘WI-FI’. When you will go on your computer and, for instance, want to sent an e-mail to your best friend. Your computer will talk in WI-FI language to the super robot and the super robot will tell this further to the computer of your best friend. The computers and the super robot can talk way and way faster to eachother than humans. This makes the internet really, really fast.

PRIVACY Privacy means the state of being apart from other people or concealed from their view. Privacy is very important in the online world. A network that you use with your device is accessible for more people than just yourself. You can have a private network, we can compare this with your own house. You can lock it, and decide yourself who can enter. A private network can be locked with a password. Unfortunatly, there are burglars out there that aim to steal your possesions. For this reason you make sure that your house is locked and your valuable possessions are out of sight. It is important that you approach a network in the same way. Make sure that your private network is secured with a password and that you don’t keep any important personal data on your device. Never share your passwords with anyone that you don’t know or trust.
When your are not at home, and there is no possibilty to connect to a private network with your device, there is often a chance that you can connect to a public network. This public networks are often Wi-Fi hotspots, that you will find in coffeeshops, airports and other public spaces. These networks are often not secured by a password, and thereby accesible for everyone. A lot of cyber criminals (criminals that commit crimes online) make use of those networks, because they are easy accesible. They can, with special software and equipment, easily detect your device and find out what your doing on your device. For this reason it is very important you don’t use any sensitive data when you are connected to a public network. Never access your bank account when you are connected to a public network. It is the same as a publc space. You don’t share your valuable possesions at an airport with others. So don’t share your valuable online data with others on a public network.

VPN Whenever you access a public network, it is best to protect your connection. This can be done with a VPN-service. VPN stands for virtual private network. A VPN service protects your network connection, to make sure that cyber criminals can not detect you. Make sure that you choose your VPN service carefully. Read the privacy policy, check the provider’s background and location, and do a little research.
