What is internet?
Internet is the world’s biggest network. Not only computers are connected to internet, but all sorts of units. In that way you can today share huge amounts of information. Typical services created for this is file-sharing, IP-phones, e-mail, streaming services etc.
Thanks to networks progression, the world’s industries, communication and day-to-day lives have changed dramatically. Internet allows work, studying and communicating from distance. This has also led to some countries introducing censorship to control free information that could jeopardise society.
In addition, internet is the reason that we have social media and as we know them today with all kinds of services it’s entailed. With more access to internet around the world, more jobs have become available that suited for the development. Online shopping is among them.
- It’s a huge network that computers and various other things are connected to.
- Has made direct communication possible in new ways such as e-mail.
- Has streamlined retail which in turn has resulted in new opportunities such as online retail.
- Today you can get almost any knowledge from internet instead of books.
- It’s a fragile system where viruses and cyber attacks appear.
- Disinformation is easy spread on internet and between users.
- Thanks to the development of internet, artificial intelligence has developed at fast pace.
Illegal file-sharing such as downloading movies, games, music, programs or anything else without paying for it. It’s considered illegal action but many still do it because internet is so fast today. As a response to this trend many companies has created successful and legal streaming alternatives such as Spotify, Netflix and Viaplay.
Another issue that often occurs on internet is cyber attacks. The most common form is a group of hackers that take control over a number of computers over distance together with overloading them by sending huge amounts of information to another server over internet, a so called DDOS attack.
Viruses occur on internet and are easily spread through e-mails, downloads or websites. A trojan file is placed in a person’s computer unbeknownst to them so a hacker easy can access their personal information such as credit-card information when you pay on internet.
Thanks to more connecting to internet, the available information is expanding. This regards anything from Youtube clip posted, Wikipedia articles or any media that is investing in web journalism. This has led to a constant access to information for humans.
The fact that internet allows fast information spreading it has led to many discussions of sources. Disinformation is easily spread over internet and it’s also oftentimes meant to confuse, or push an opinion sin a certain direction, for example during elections. Checking sources is therefore crucial just like in traditional media.
Internet is also the technique that will lead us into the future with AI, artificial intelligence. Thanks to internets progression, huge amounts of data will allow AI to develop and keep updated with the latest information such as autonomous driving cars.
In your mobile phone
Today we carry our mobiles wherever we go and we use them for almost everything. In the past, mobile was used to make calls and text messages, but as we now have access to the internet in our phones, the areas of use have increased significantly. Initially, the internet connection to the mobile was something for those with good patience. It just went super slow. But through the different generations of mobile networks, 2G, 3G and 4G, the speed and accessibility has increased somewhat immensely. And now we are facing the next step, namely 5G.
When more and more mobile devices are expected to connect to a wireless internet, much more will be required when it comes to speed, throughput and delay. This is something that 5G is expected to do without any problems. It is talked about that 5G will be able to deliver speeds of up to 100 megabits / s with a delay of as little as a millisecond. In this way, self-driving cars will be able to make decisive maneuvers in no time and many units will be able to connect to the Internet in the same place, for example at concerts etc. where this has before caused problems.

Internet of Things
5G was created to carry, what we call IoT, the Internet of Things. The Internet of Things, simply put, means that things will connect to the Internet and thus become “smart”. Today, we are used to the fact that phones and computers are connected to the internet. But the Internet of Things means that other things will also be connected.
But how can the Internet of Things help us in our everyday lives? The possibilities are endless. Think about, for example, your bike is connected to the internet and can log how much you have cycled each week. If this is then linked to your laundry bookings, a washing time can be automatically booked after cycling seven times, because then your appliances know that you have a lot of dirt cleaning.
