Human life in the modern world cannot already be presented without the Internet which opened a huge number of opportunities for people. At the same time the conducted surveys showed that a large number of users cannot accurately answer what is the Internet. It is worth understanding this subject and to give definition to the main terms.
What is the Internet and as it works?
If to speak a simple language, then the Internet is a large number of the computers located in different corners of the world and connected with each other by means of communication channels which are intended for obtaining information. As a result the global network consisting of a server and client part turns out. Describing what is the home Internet, it is necessary to specify that the most important – the software installed on servers which are the powerful computers capable to accept and process a lot of information.
What is the Internet connection?
To use network it is necessary to be connected to it. For this purpose there are several options. It is worth noticing that the quantity of ways of connection to network constantly increases, so, the most widespread are for today:
- FTTB (ETTH). The most popular technology which principle of work is that the switchboard connecting to service provider is installed. Into the apartment or the house enter twisted couple which is connected to the personal computer or the router. Speed limit is 1 Gbit a second.
- xPON. The fiber-optic channel is the most progressive and modern way of connection. The possibility of connection of the Internet is caused by the organization of the gigabit channel with services of Tripple Play. For connection the optical cable is carried out.
- GPRS and 3G (above). The mobile Internet is in huge demand. With its help the person can be connected practically in any place, but at the same time there are limited limits. Speed of such Internet grows every year.
- Satellite communication. This option of connection can be unilateral at which connection works only for reception of information, and for transfer the usual communication, and the second option – bilateral at which both reception, and transfer is possible is necessary.
- WiFi and WiMax. Extensive wireless networks carry out in most cases in places of a big congestion of people.
What is the speed of the Internet?
Or are transferred by the maximum number of data which are accepted by the computer to network per concrete unit of time, call the speed or capacity. The most widespread options of measurements: Kbps and Mbit/sec. It is interesting to learn what fastest Internet in the world, so, it is registered by the Economic Cooperation Organization in Japan. Residents of the country have more than 60 Mbit/sec. The factors influencing speed:
- the chosen data plan;
- technology of the transmission channel;
- load of network with other users;
- speed of loading of the websites;
- work on the computer of programs and applications;
- setting up operating system and computer.
What is Internet service provider?
The company providing to users Internet access and other services connected with it is called as provider. He can be primary or secondary. Practically each provider offers several data plans at choice. If interests what most favorable Internet, it is necessary to specify that data plans differ in the access speed, existence or lack of volume of the transmitted data. The choice should be made proceeding from own requirements.
What is the Internet the address?
For contact with any computer in network it is necessary to know the unique Internet address. There are two formats differing in the form:
- IP address. The possibility of the modern Internet assumes use of IP of the fourth version. It turns on four blocks of figures which can enter number from 0 to 255.
- DNS address. As addition to the IP addresses the domain name system transforming alphabetic names of domains to the IP addresses was thought up. The DNS address contains the alphabetic reductions divided into separate blocks.
What is traffic on the Internet?
Understand the mathematical indicator determining the speed and volume of exchange of information as this term. Measure quantity of traffic in Gbyte, MB, Kb. Appropriate will be to specify what is the unlimited Internet, so, understand right of access without any restrictions neither on volume of the obtained information, nor on time spent in network as it. Divide traffic into two groups: entering (the obtained data) and proceeding (the sent data).
What is WiFi the Internet?
This concept is not understood as Internet per se as it is the modern standard of data exchange between different devices which have special radio modules. If you deliberate what Internet it is better to connect, then, it is clear that the wireless network is more convenient. Now the WiFi modules are installed in all modern equipment, so, it is not only in phones, but also in cameras and even multicookers.
For access to the network by means of WiFi the access point is necessary. In most cases in this role the router – the device which looks as a small box with antennas and a set of nests acts to attach the wire Internet. Besides, the laptop, the smartphone or the tablet can be a point of access. Regularly the cities become covered by access points more and more.
History of development of the Internet
In far 1957 the Ministry of Defence of America decided to create a new system to exchange data between the supreme state agencies of the USA. As there was a Cold War, wanted to create a backup system of exchange of information. The advanced developments agency put forward the idea to create the network connecting computers. The history of the Internet specifies that the plan was transferred to the advanced American universities. The first small network ARPAnet appeared by 1969, and it interested in the Ministry of Defence which began to allocate funds for its expansion and completion.
Finding out what is the Internet and when it appeared, it is worth specifying that in 1973 the network became international when Americans carried out a cable which connected departments of America with the government organizations of Norway and Great Britain on a bottom of the Atlantic Ocean. All the time the ARPAnet network extended and improved. Carry out the first standardization in 1983, and same its year began to call the Internet.
Possibilities of the global Internet
To Internet users assumes a large number of opportunities which regularly extend.
- Information search. A simple task for which the search engine is used.
- Work. The Internet allows people to carry out sales, to advertize the business, to look for work, to invest money and so on. Possibilities of the Internet give a chance to construct successful business.
- Training. Many people use the Internet for obtaining new knowledge. Here it is possible to obtain not only the training information, but also to complete different courses, lessons, to receive programs, video and so on.
- Entertainment. Probably, each person at least once used the Internet for rest and entertainment. For this purpose there is a large number of games, movies, programs and so on.
- Communication. Describing what is the Internet and what opportunities it gives to the person, it is necessary to specify that this excellent means for communication between people. In network there are different portals, forums, social networks, messengers and other ways for communication with people worldwide.
