What is the Internet?
The Internet is a large group of computers that are linked
together. There are millions of computers connected to
this network across 200 countries. The users of these
computers can communicate with each other by sending emails, transferring files, instant messaging, etc. Every
computer that is connected to the Internet has a unique address, which is called an Internet Protocol Address (IP
Address). The IP address is a series of numbers separated by dots, for example: 123.45.67.890.
How does it work?
Computers that are connected to the Internet have different functions. Computers (users) that get information on
the web are called clients. Other computers (servers) only store files such as photos, music, emails, videos or websites.
A client can access a server to visit a website, check an email account, etc.
When two computers exchange information, they are called peers. Some examples of this are instant messaging or
sending photos to a friend directly. When two peers interact with each other it is called peer-to-peer (P2P)
communication. For example, if you receive a photo from your friend, your computer is the client because you access
the file and your friend’s computer acts as a server because he or she supplies the photo.
Who invented the Internet?
In the 1960s, researchers from the Government Defense Department in the United States were looking for a way to
continue working in case some computers were damaged due to a war or natural disaster. They came up with a
network that linked several computers
together. In 1969, their network began
operating and was called the ARPANET.
Over the years, universities, large
businesses, and other major
organizations joined this network to
exchange ideas and resources with each
other.

Cyber Crime ONLINE CRIME
Cyber-crime is one of the fastest growing crimes in the world.
Frequent users of the internet buy things from online shopping
platforms, perform online banking, and store their files on a
‘cloud’. These events provide endless opportunities for cyber
criminals who take advantage of the weaknesses of others.
More than 70% of all Americans have experienced some form of cyber-crime in their lives. Most of these illegal online
activities are hard to detect and solve. In many cases, victims of cyber-crime do not even realize that something illegal
or illegitimate has taken place.
Basically, there are three types of cyber-crime:
• Harassment – Some people use the Internet anonymously and are engaged in illegal activities like
stalking, harassment, and bullying.
• Hacking – Hackers break into online networks and try to corrupt or download all kinds of sensitive or
valuable information.
• Phishing – Phishing is the activity of sending emails to people trying to trick them. The purpose of
phishing is to obtain money from the recipients of these emails. Usually, the elderly, who are not very
computer savvy are the most vulnerable groups for this kind of crime.
ANONYMOUS Anonymous is a group of hackers that is famous for their distributed
denial-of-service (DDoS) attacks. They target organizations such as
governments and large companies. A DDoS attack is a process in which
many computer systems attack a single target, such as a website or a
server. The enormous number of incoming messages (attacks) slow
down the server so that it cannot be used anymore.
1) Cyber-crime is the most common crime in
the world.
2) Online bullying is a cyber-crime.
3) More than half of the American population
has been affected by cyber-crime.
4) Cyber-crimes are hard to detect and solve.
5) Inexperienced Internet users are more
vulnerable to cyber-crime.
