The internet is the biggest world-wide communication network of computers. It has millions of smaller domestic, academic, business, and government networks, which together carry many different kinds of information. The term is sometimes abbreviated as "the net". The World Wide Web is one of its biggest services. It is used by a few billion people all over the world.
The internet was developed in the United States by the "United States Department of Defense Advanced Research Projects Agency" (DARPA). It was first connected in October, 1969, and was called ARPANET. The World Wide Web was created at CERN in Switzerland in 1990 by a British (UK) man named Tim Berners-Lee.
Today, people can pay money to access the internet from internet service providers. Some services on the Internet cost nothing to use. Sometimes people who offer these free services use advertising to make money from them. Censorship and freedom of speech on the internet can be controversial.
Services on the internet[change | change source]
The internet is used for many things, such as electronic mail, online chat, file transfer, and the interlinked web pages and other documents of the World Wide Web.
The most used service on the internet is the World Wide Web (which is also called the "Web"). The Web contains websites, including blogs and wikis like Wikipedia. Webpages on the internet can be seen and read by anyone (unless the page needs a password, or it is blocked).
The second biggest use of the internet is to send and receive e-mail. E-mail is private and goes from one user to another. Instant messaging (such as AIM or ICQ) is similar to email, but allows two or more people to chat to each other much faster.
Some governments think the Internet is a bad thing, and block all or part of it. For example, the Chinese government thinks that Wikipedia is bad. Many times no one in China can read it or add to it. Some parents block parts of the internet they think are bad for children to see. Well-known examples of the whole internet being blocked are in North Korea.
Dangers on the internet[change | change source]
The internet makes communication easy, and communication can be dangerous. People often send secret information, and sometimes other people can steal that information. They can use the Internet to spread lies or stolen secrets or dangerously bad advice. For example, Facebook has had some problems with privacy settings. A person can post information on the website, but this is often a bad idea unless the person is very sure of what they are doing. One way to check for a secure website is to make sure the URL starts with https:// instead of http://. This means it is secured so other people cannot read information while it is being sent. However, it does not mean the website will do things to keep it safe.

Nowadays almost everyone in the world have had a contact with computers. A great part of them has been using international computer’s net known as Internet.
I think using internet has more advantages then disadvantages. First of all, Internet provides access to a lot of information. Some of them are very useful in your job other helps in your hobby. Searching the net with Google, you can find everything you want. You can also do shopping using Internet. Of course it has no sense to buying a roll, but if you need something inaccessible, you will be able to buy it in Internet shop. You need only to select what you want, fill in some forms and click ok. In a few days you will get what you have ordered directly to your home, without going anywhere. You can pay with your credit card, pay postman when you get the package, or transfer money from your bank account. Nowadays almost every bigger bank offers transferring money with Internet. It is more faster then going to the bank and filling blankets. Transferring money in traditional way takes about a day, using Internet you can do this in few seconds even in Saturday and Sunday evenings. What’s more internet banks give you insurance against unauthorized transaction. Some people thinks that their money can by easily stolen by hackers. It isn’t true because the easiest way to steal your money from internet bank is breaking to your house and stealing you card of codes. Internet banks have very good protections witch make them practically unbreakable.
Next advantage of internet is email. Internet mails get in a few seconds in their destinations. It is very important when you want to send something for example to Australia. Of course you can send not only texts. You can email whatever you want, movies, photos, songs, computer programs etc. Costs are very important advantage of emails. Sending an email is much cheaper then phoning, or sending normal letters.
Beside a lot of advantages, Internet has some disadvantages too. First of disadvantages is that people who spend too much time sitting in the front of computer can easily gets ill. Radiation emitted by computer’s screen is harmful to eyes. People who spend too much time at their homes (because they needn’t go anywhere, they can do everything using Internet) are getting weaker. Sitting a for long time is also harmful to the spine.
Second disadvantage is that Internet can by addictive. Some people just can’t live without it. They have no real friends and when Internet is down they are getting furious.
Internet has some opponents but more and more people treats Internet like telephone, or radio. They use it for fun and work, and I think at present living without internet would be quite difficult.
