The internet is used all around the world.Social media has a big effect in our lives.We use it and need it.The internet is a small but it may cause harm.We just want to be safe from cyber bullying,pornography and even bad comments that may cause harm.It may cause a child to have trauma.

Here are five tips to be safe

  1. Make sure to have an adult by your side whenever you use the internet
  2. Never lie. Lying will take you nowhere make sure to tell the truth
  3. Never follow or add people you don’t know offline
  4. When you are suspecting or feel something is wrong,tell an adult IMMEDIATELY
  5. Follow these rules and be safe 😄

Being safe is what we all want,but we must not forget to help others too.We all want to enjoy the internet happily but where did the internet come from.Read this👇

It doesn’t seem a likely spot for a major act of innovation. But 40 years ago this August, a small team of scientists set up a computer terminal at one of its picnic tables and conducted an extraordinary experiment. Over plastic cups of beer, they proved that a strange idea called the internet could work.

The internet is so vast and formless that it’s hard to imagine it being invented. It’s easy to picture Thomas Edison inventing the lightbulb, because a lightbulb is easy to visualize. You can hold it in your hand and examine it from every angle.

The internet is the opposite. It’s everywhere, but we only see it in glimpses. The internet is like the holy ghost: it makes itself knowable to us by taking possession of the pixels on our screens to manifest sites and apps and email, but its essence is always elsewhere.

This feature of the internet makes it seem extremely complex. Surely something so ubiquitous yet invisible must require deep technical sophistication to understand. But it doesn’t. The internet is fundamentally simple. And that simplicity is the key to its success.

The people who invented the internet came from all over the world. They worked at places as varied as the French government-sponsored computer network Cyclades, England’s National Physical Laboratory, the University of Hawaii and Xerox. But the mothership was the US defense department’s lavishly funded research arm, the Advanced Research Projects Agency (Arpa) — which later changed its name to the Defense Advanced Research Projects Agency (Darpa) — and its many contractors. Without Arpa, the internet wouldn’t exist.

As a military venture, Arpa had a specifically military motivation for creating the internet: it offered a way to bring computing to the front lines. In 1969, Arpa had built a computer network called Arpanet, which linked mainframes at universities, government agencies, and defense contractors around the country. Arpanet grew fast, and included nearly 60 nodes by the mid-1970s.

But Arpanet had a problem: it wasn’t mobile. The computers on Arpanet were gigantic by today’s standards, and they communicated over fixed links. That might work for researchers, who could sit at a terminal in Cambridge or Menlo Park — but it did little for soldiers deployed deep in enemy territory. For Arpanet to be useful to forces in the field, it had to be accessible anywhere in the world.

Picture a jeep in the jungles of Zaire, or a B-52 miles above North Vietnam. Then imagine these as nodes in a wireless network linked to another network of powerful computers thousands of miles away. This is the dream of a networked military using computing power to defeat the Soviet Union and its allies. This is the dream that produced the internet.

Making this dream a reality required doing two things. The first was building a wireless network that could relay packets of data among the widely dispersed cogs of the US military machine by radio or satellite. The second was connecting those wireless networks to the wired network of Arpanet, so that multimillion-dollar mainframes could serve soldiers in combat. “Internetworking,” the scientists called it.

From Theguardian.com

It is a very fascinating story here’s another version.

The Internet started as ARPANET, a 1960s defence force project in the US which had the objective of connecting several super-computer sites in the country with one another so that if any one of them was destroyed by a nuclear explosion, for example, then the remaining computers would continue to function.

This early, geographically-dispersed network proved to be so successful (remember, this was in the days when computers were large unwieldy creatures that often ‘crashed’ without the help of explosions of any kind), that soon other large computer sites located within universities, government departments and large corporations began linking to this network.

As this network grew, so its benefits and advantages quickly became apparent. Academics, officials, technicians and scientists could communicate with each other quite easily and were readily able to share information. It increasingly attracted the attention of organisations outside the US and as other countries joined the network they helped it grow even faster.

This internationalisation of the Internet helped give its name — an INTERnational NETwork; hence Internet.

Of course, with improved technology and supporting infrastructure, the Internet eventually became available to smaller computer networks and to individual users. From being an unfriendly, command-driven environment, the Internet was friendly to use. The advantages of having huge amounts of information available at your finger tips and accessible in a user-friendly way, helped in attracting the large numbers of users that we see on the Internet today, already numbering in excess of 670 million.

It has a very interesting story.And it had a lot of flaws but it came to exist , using it safe will make you enjoy it

I hope you enjoyed reding this😀
