Introduction to Internet

Published:

Introduction to Internet is the denomination of a set of information resources in the world. These resources are so vast that they are beyond what we can imagine, in fact it can be considered as a “chaotic” environment of computers.

Internet allows traveling in cyberspace (virtual, non-geographic space, determined by the interconnection of people through telematic networks. A term that was coined by the North American writer William Gibson in his scientific fiction novel Neuromancer, published in 1984.

Gibson initiated the movement called cyberpunk) using any type of computer, be it, for example, a compatible PC, an Apple, a Sun workstation or even a cell phone (especially if it is a smartphone type).

Origin of Internet

The origin of the Internet comes from a series of computer networks developed in the 1970s. It began with the network called Arpanet, managed by the US Department of Defense. It was later expanded, giving rise to what we know today as the InternetIntroduction to Internet.

In Spain it was introduced from the Red Iris, currently dependent on the public company Red.es, being the Introduction to Internet provider (ISP) of all Spanish public universities. We can realize how technology has evolved if we consider that the first experimental network was created in 1969 with only four computers, 12 years later, with the arrival of the IBM PC, networks with hundreds of computers began to spread.

Networks

It would be a mistake, however, to consider the Internet only as a network of computers, a group of interconnected networks. Computer networks are simply the medium that transports information, which is the most useful thing about the Internet. The Internet allows millions of people around the world to communicate and participate and also to share information.

To access the resources offered through the Internet, it is not necessary to know any programming language, nor even to know in detail the operating system under which our computer or the rest of the computers on the network work. The term network means the union of two or more computers with each other. There are a large number of reasons that justify the existence of the Introduction to Internet, the two most prominent are:

Allow users to communicate

For example through email, messaging systems and social networks.

Sharing resources (for example, the old Seti project for the search for extraterrestrial life, which has currently been included in another project, BOINC, sponsored by the National Science Foundation of the United States, which encompasses multiple projects with large calculation needs).

A local area network (LAN) is a network in which computers are connected directly, usually with some type of cable (although Wi-Fi wireless networks are gaining ground). WAN (also known as MAN) is a computer network that covers a relatively large geographical area.

Typically allowing multiple organizations such as government offices, universities and other institutions to connect on the same network. Most WANs are linked by telephone and fiber optic lines, although sometimes by satellite.

Introduction to Internet Personal Networks

PAN are personal networks, of very small scope. As can be deduced, fast communication is achieved on the Introduction to Internet, however sometimes th.re are problems, most of the bottlenecks that occur with some frequency are due to the low quality of some lines or intentional saturation, such as the well-known cases of “denial of service” attacks.

Next, the advantages of the Internet are cited, copied from an advertising proposal by a group of prominent bloggers, headed by Ricardo Galli, creator of Meneame.

Yes to internet

The Internet has allowed the development of tools such as free software (open source) and Wikipedia. Being the cheapest and most efficient method of knowledge and technology transfer to less developed countries.

Never before has so much knowledge been within our reach with a few “clicks” of the mouse. Knowledge has become a common good that is not scarce. It is not necessary to spend thousands of euros on paper encyclopedias so that children can access the necessary knowledge for an up-to-date, skeptical, global and tolerant education.

With blogs and social networks we have overcome the stage where we thought that the Internet would serve to have thousands of television channels from the same companies, now we are the people, each one of us, the protagonists.

On the internet we have become accustomed to freedom of expression and debate of ideas, that is why we defend them. Each blog is a small contribution, the blogosphere is the visible testimony.
