Under the information technology and systems implies discipline, which included the creation and management of data through computer technology. Often, by means of information technology computer equipment, but it is a broader concept.

 

This is a complex, scientific and engineering disciplines involved in the organization of work of people associated with the collection, storage and management of information, as well as computer science.

 

As to what kind of information technologies and systems greatly influenced my life I will write next.

 

First - this is a device called a computer.

The advent of computers has committed our lives to the revolution. They have changed the way we work, study, leisure and other aspects of life.

Today, computers are used in all areas of life, such as medicine used computed tomography, transport - traffic management, science - in the calculations and modeling processes.

At this point, the computer has an important role in everyone's life. But it also has its pros and cons. Pros are that, with the help of a computer, we can find the information we need on the Internet, we can communicate with people who can play, have fun, make people laugh to watch videos, write research papers, develop. Disadvantages are that the computer does not really even good for the human body. If it is too long to spend their time at the computer, your vision will quietly go bad. Sometimes it can get sick head sharply. A dependence that is poorly vliyat per person, takes away a lot of free time. I spend a little time at the computer, only to have all the right. I think this is an important discovery for mankind. Main abide by the rules and spend some time surprising number next to it.

 

Second - this is the internet.

Among all the discoveries I've made in my life, there is one huge and difficult to understand, making you forget all the others - is opening the Internet.

I do not remember when was my first dive into the virtual world of millions of computers, but remained in my memory, the memory of the first page, which I got. Joy - that's what I felt then and what will never forget never understand until the end of the cause of that joy. Maybe my old dream has come true, maybe page was very beautiful, and maybe made me rejoice in the miracle that strange codes in some distant city from me overcome thousands of miles and passed through the telephone wires and display the on-screen colors, shapes, human-friendly names. Yes, otherwise you can not call it. Miracle ...

 

Third would be fair to mention smartphones.

Due to the constant development of electronic technology in the market today, a host of so-called "thinking" phones. Models with built-in microprocessors revolutionized in their environment, because now there are completely different devices possible.

The differences between smartphones and regular handsets simply stunning. In newer phones, a host of additional features, increased memory capacity, quality and quantity of information transmitted, it became higher resolution camera, accelerated access to the Internet.

For "smart" is without a doubt the future. However, during the operation revealed one is not a very pleasant thing, "smart" phones have been extremely finicky. Most of their damage associated with mechanical failures. We can recall little functional, but strong are larger models that are jokingly called the "Nutcracker." They dropped to the floor and into the water, get a crack at them, but after assembly and drying machines work as before. In case of serious damage can be easily replaced or screen housing.

Smart phones are totally different. Fragile and capricious circuits protected by a plastic cover, even at weak shocks and vibrations may be damaged. Contact with water categorically excluded, as internal nodes instantly oxidized and the unit becomes useless. Repair of these models is more complex and costly than repairing laptops.

 

Fourthly, I would like to say about GPS navigators.

GPS (Global Positioning System - Global Positioning System) - a satellite navigation system for the measurement of distance, time and determines mestopolozhenie. Allows any location (not including polar region), almost any weather and in space near the planet determine location and speed of objects.

The basic principle here - the determination of the location by measuring the distance to the object from points with known coordinates - satellites. Distance is calculated from propagation delay time from the sending it to a satellite receiving antenna GPS-receiver. That is, to determine the three-dimensional coordinates of GPS-receiver needs to know the distance to three satellites and the GPS time system. Thus, to determine the coordinates and height of the receiver signals are used with at least four satellites.

 

And in conclusion I would like to say about social networks.

Not everyone knows that the concept of "social network" has appeared in 1954, and nothing to do with the Internet, of course, was not the case, and to study the phenomenon began in the 30s of the last century. Concept was introduced by sociologist James Barnes: "social network" - it is a social structure made up of a group of nodes, which are social entities (people or organizations), and the connections between them (social relations) (more on Wikipedia). In more simple terms - it is a certain group of people they know where the person is the center, and its familiar branches. Between all members of the network have bilateral or unilateral constraints. For example, it may be a group of fellow students, which is the center of a Jack and Bill and Catherine his friends (branches).

The impact of social networks on people's lives is huge, many do not even realize until the end of this phenomenon, and in fact the social network - this is the most popular activity on the Internet. Today, of the 100 most visited websites in the world's top 20 - a classic social networks and another 60 - to some extent socialized. More than 80% of companies worldwide use social networks at work. About 78% of people trust information from social networks. They even arranged through the whole revolution. Social networks have become the center of the modern Internet.
