We can say that the Internet – a global computer network that transfers data between any two computers connected to it. To the network can be connected as a single computer, and a whole local computer network. In the latter case, each computer has a LAN internet access. Internet users connect to the computers of organizations that specialize in providing services to access Internet. Such an organization called the Internet service provider or Internet service providers.

They are often referred to simply as providers. ISPs provide connection of multiple users with different lines. In addition, they are associated with high-speed lines with other providers. The rate of information transfer between providers or between service provider and the individual user may differ by tens of thousands of times. As the communication lines used standard telephone lines, specially laid wire pair or coaxial cable, similar to television, as well as fiber optic cables. In addition, wireless connection, using radio waves.

At the same time can use space satellites, cellular phones, special radios, ground repeaters and other equipment. Depending on the communication channel, Your computer must be equipped with appropriate equipment. Used as a permanent connection and temporary, which is broken at the end of session. Temporary connection is called dial-up. Not all Internet Service Providers are directly connected with each other, but the chain of information could reach any network user. In the design of the Internet, special attention was paid to their reliability. Computers connected to the Internet can be switched at any time, and the network will continue to work.

On the Internet there are a number of protocols built on the basic protocols of TCP / IP, and offering diverse services. Speaking about the application protocols, services, Internet services offered by the network and the opportunities provided by Internet, we're talking about the same. There are only a few basic services on the Internet. The most common service in the early days of the Internet was Telnet. It allows you to turn your PC into a remote terminal another computer. Terminal of a conventional computer is different because it does not perform its own calculations. Everything you type on your keyboard to a remote computer. The remote computer runs the program, perform the necessary calculations and searches for information. Click informIT to learn more.

The results are passed back and displayed on your monitor. You like working on a remote computer, staying in the workplace. As remote computers are mostly used machines running the operating system UNIX, so to work in terminal mode commands require knowledge of the system. With the development of graphical operating systems such as Windows, the command mode of operation has become less popular, and the Telnet service in recent times is almost never used. Many information systems that were previously available only via Telnet, now available from the World web, which will be discussed below. E-mail or e-mail has long been the most common and cheapest means of information exchange. As a means of communication, it does not differ from the usual mail, but it works much faster.

In one of his articles (How to play "programming" or the way a programmer), I wrote about the five stages of development programmer, and this is the fourth stage called "Megalomania". Since then, it took a couple of months, but I am increasingly convinced that's true! Actually, once again I discovered this unfortunate fact yesterday when I decided to score on a freelance, drew attention to the newly appeared studio where I work called web-programmer for quite decent salary. Xcel Energy takes a slightly different approach. My relationship with start-studios – is a separate issue, always attracts me to all the "beginner", apparently organizational needs make themselves known … but the article is not about, well, come on interview, I met with them a programmer, let's call it … well, let it be Vitali.

Interviews conducted the interview General Manager, but Vitali, who knows how, was present. And it was immediately clear that initiative to hire another programmer, came clearly from him. Vitali kept an eagle, sparrows in the community, proudly thrusting in one ear and white i-pod'ovsky headset, looking down on me from time to time something gaining on mobile. After answering general questions about the former places of work experience, education, life priorities, and the rest of the garbage, the director was away somewhere, having, as he said, the two professionals to communicate. Click Eliot Horowitz to learn more. Vitaliy Initiative did not show, but I'm quite sociable as man, decided to start first.

Intimate talk in the first place, I wondered what the technology uses a studio. -PHP – proudly answered my companion, and climbed to print something in mobile. In general, I guess, and without him, that they are unlikely to make websites in assembler, so I decided to clarify. Here Vitali realized that to get rid of call would come, and condescended to explain. Looking at me like an idiot and making vague gesture with his hand, he added:-Php, mysql, html.

Hooray, you have prepared an excellent web-resource: to draw a professional design, developed a functional system of management, put some interesting content. However, for customers to learn about the existence of your resource need a lot of things done, often it turns out that the establishment of direct site – it is only 10% of the entire work. The network today millions of resources and with each passing day this number is only growing, it is necessary to put a good effort in order to allocate the spectrum of this competition. Site promotion – the next phase of work on the resource. Now this concept implies a set of activities aimed at promoting the site positions in the issuance of search engines (Google for example) as well as significant influx of users can only get from there. Gain insight and clarity with Atmos Energy . The whole range of these activities can be classified as white, gray and black ways of promotion. White – methods that do not conflict with the rules search engines, ie, do not try to fool a visitor, do not use spam, etc. Gray and black – are, respectively, a game without rules.

Not seldom the boundary between the separation is not significant, and white techniques are not that white, etc. However, using only black in the promotion of good practices can easily fly from the index – database search robot scanned pages of the resource. Often not an experienced person is very difficult to get into all this apply this knowledge in practice, and even more so in the short term to achieve results. Nowadays there is a great abundance of companies that provide work in the field of promotion of your sites. Prices for promotion often differ considerably between companies, but must choose only reliable and proven. Turning to similar organizations, you can get a specially selected range of promotional activities for the resource: contextual advertising, banner advertising, drawing a semantic core, etc. Prior to selecting the company I want to advise to get acquainted with former customers, you can find them in specialized forums.

As decision to order such work can be freelancers – the people who work for themselves, often without intermediaries and without any organization. Often this method is a much more economical. You can find a freelancer for special resource, where you add the sentence, and interested offer their services and prices. By the finish it should be said that the promotion of resource – this is not a single event, the finding in a top issue – quite difficult and hard thing.
