What is the internet

The name Internet comes from the English words Interconnected Networks, which means "interconnected networks". Internet is the union of all the networks and computers distributed all over the world, so it could be defined as a global network in which all the networks that use TCP / IP protocols and are compatible with each other.

In this "network of networks" as it is also known, computers of all kinds, from large systems to personal models. In the network, there are official, governmental, educational, scientific and business institutions that make information available to millions of people.


Internet was the result of an experiment of the Department of Defense of the United States, in 1969, that materialized in the development of ARPAnet, a network that linked universities and centers of high technology with contractors of that department. It was aimed at exchanging data between scientists and the military. The network was joined by nodes from Europe and the rest of the world, forming what is known as the World Wide Web. In 1990 ARPAnet ceased to exist.

What are the networks

The computer network names the set of computers and other interconnected equipment, which share information, resources and services. It can be divided into different categories, according to their scope (local area network or LAN, metropolitan area network or MAN, wide area network or WAN, etc.), their method of connection (coaxial cable, fiber optics, Radio, microwave, infrared) or their functional relationship (client-server, person-to-person), among others.

Tics in everyday life

THE RISE OF TECHNOLOGY

Technology has always been a part of man's life. Since prehistoric times, man has used his intelligence to create technologies that allow him to have tools with which to make better his work, for example through the creation of lances using stones which polish to make them more sharp and with it To be able to hunt animals.

The technology since that time and motivated by the needs of man, has evolved in an accelerated way until today, when many human actions are made with inputs and technological products of a computational nature.

Informatics in general has covered different areas of human life and today are an essential point in economic or social matters for example.

The technology from the economic sphere is the support of the current phenomenon of globalization that allows an accelerated commercial exchange through the possibility that all the society of the world of being interconnected in real time, originating what has been called "global village" .

In the social sphere technologies have caused great changes in the possibilities and ways of communicating of the human being, being one of the most important innovations the irruption of social networks or the possibility of communicating in real time through text, audio or image .

In this way we see how technology covers much of human life and contributes to the development of man in the future.





Cloud Computing
Cloud computing is a general term for anything that has to do with the provision of hosting services over the Internet. These services are divided into three broad categories: infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS). The cloud computing name was inspired by the cloud symbol that is often used to represent the Internet in images and flowcharts                               

Ergonomics

Study of the adaptation conditions of a workplace, a machine, a vehicle, etc., to the physical and psychological characteristics of the worker or the user.

Work environment

Is a term originating in the Latin ambĭens, which means "surrounding". This notion refers to the environment that surrounds living beings, conditioning their vital circumstances. The environment, therefore, is formed by diverse conditions, as much physical as social, cultural and economic

Computer related health problems

1. Carpal Tunnel Syndrome:

The main illness that people addicted to chatting with and chatting with other people can suffer. Carpal tunnel syndrome is a disease that occurs when the nerve that goes from the forearm to the hand is pressed or trapped inside the carpal tunnel at the wrist, causing numbness, pain, tingling, and weakness in the affected hand .

2. Damage to hearing:

If you listen to music on loudspeakers, you risk hearing problems. The first and most important is hearing loss (deafness), problems in the balance (this sense is in the ear) and in the short term, nausea and vomiting.

3. Mental problems:

The technology used in excess brings important health consequences. Many people have diseases such as depression, social isolation, anxiety, loss of pleasure and enjoyment of daily activities, among other psychological problems.

4. Overweight and obesity:

A recent study confirmed that people who spend so much time in front are more likely to be sedentary, and therefore, overweight and obese, diseases that lead to other problems such as diseases in the circulatory system, diabetes, among others.

5. Irreparable damage to the nervous system:

Abusing the technology can cause irreversible damage to the central nervous system, as the electromagnetic fields they emit cause diseases such as vertigo, fatigue, sleep disorders, memory loss and development of brain tumors.

6. Eye diseases:

Staying for hours watching the screens of a computer or television can also bring problems in the eyes. The most common are: dryness, eye strain, etc. The recommendation is to take active breaks to relax the eyes from exposure to these elements.

7. Addiction:

The obsession with technology is a reality in the modern world. So much this is already cataloged as a disease by specialists. And there are several: there is the nomophobia (fear of not having the cell phone handy) portatilitis (muscle aches and pains to use and load laptops in excess) cyberaddiction (Internet addiction).Environmental Impact

Environmental Impact

Environmental impact on the environment is the effect of human activity on the environment. The concept can be extended to the effects of a natural catastrophic phenomenon. Technically, it is the alteration in the environmental baseline.

Ecology is the science that is responsible for measuring this impact and trying to minimize it.

People's actions on the environment will always have collateral effects on the environment. Concern about environmental impacts encompasses several types of actions, such as pollution of the seas with oil, radioactive waste or radioactive / nuclear waste, auditory pollution, emission of noxious gases, or loss of habitat area Natural, among others.
