What is a Proxy Server and How Does it Work?

A proxy server is a so-called “proxy computer” that a user can use to access the Internet. The main purpose of its existence is to broadcast all the user’s requests to the Internet and send back the responses received. In this article, we will consider in detail what a proxy server is, what it is used for, what are its principles of work and what kinds of proxy servers there are.

What is a proxy server?

As previously mentioned, the proxy server is the third link that connects the user to Internet servers. It acts as a kind of intermediary which separates the user from the site he visits. The proxy creates special conditions under which the site will recognize him as a real person who visited the page. Such servers are very useful and versatile, so they can be used in many cases: 

  • The server gives you privacy on the Internet. The site will not be able to recognize your real identity
  • Proxy provides a high level of safety when surfing the internet and all basic attacks from malware will be handled by a proxy
  • It allows you to access information that is not available in your location
  • The proxy can speed up access to certain webpages
  • Gives you access to blocked content and applications

It allows you to do all these things because it changes the IP address and the traffic is additionally checked.

How a proxy connection works

We talked a little bit about this in the previous paragraph, and now we will continue this theme. Initially, each computer is assigned its unique IP address, which identifies your identity on the Internet. It can provide all the information you need about you, your country, your region of residence, your computer number, and your Internet service provider.

Proxy servers also have such IP addresses and after you connect to them their IP address will be shown instead of yours, and you can remain anonymous. To connect to the proxy you will need to go into the settings of your browser. All subsequent network connections will be made to the IP address of the proxy server.

Types of proxy servers

Proxy servers come in different types and purposes. And below we will describe each of them: 

  • Transparent proxy – mainly used in public institutions and schools. Such a server will not conceal any information about you from a website and will honestly tell you that it is a proxy
  • Anonymous proxy, like the first one, does not hide what it is but will keep the user’s data secret. So this type of server will provide faceless information to both sides 


Distorting proxies – These proxies provide untruthful information to internet pages about the user who visited them. Thus, the sites will not suspect anything and will behave as usual

Private Proxies: These proxies protect your IP address by changing it every time and providing fake data, preventing the monitors from following your traffic

HTTP proxy is the most common server used for web browsing

What is Primary Data?

To carry out a successful statistical study, one of the basic and most important elements that help in data acquisition, in which primary data are the most important.

Primary data is one of the two basic forms of data, or in short, it is the simplest of all data that is required for statistical processing. This article will tell you everything you need to know about the types of primary data.

What is primary data?

Primary data are those “raw” and “unprocessed” data that investigators assemble straight from primary sources: polls (online or live), interviews, experiments, and so on. This is why they are regarded as the best type of data because they come from reliable sources.

But before you start any research, you need to determine its goals and target group. Who might want your experiment? The sources from which you will extract primary data are also selected and tailored precisely to the demands of the specific source.

Examples of primary data

We’ll provide a few examples to illustrate how primary data collection occurs.

  • Market research

Carried out primarily as a point of a major line of business planning, the market survey gathers data about the target market and customers

Companies that perform market studies on a new product they are about to release (let’s say a phone) collect information on customer purchasing power, feature preferences, and many other things that may be involved in using a smartphone. A new study needs to be done each time, as the results of the previous ones will be considered irrelevant due to product changes.

  • Student Dissertation

This type of research, as has become clear, is done by students when writing a diploma or any other research paper. The types of data will also depend on the type of research: laboratory, social, statistical, and so on.

For example, a student who wants to find out how eating fast food affects a person’s weight would have to select several people, feed them fast food every day, and record changes in their weight. This will be called primary data.

  • Surviving trauma

Everyone experiences trauma differently, whether it is physical or psychological trauma. If you want to do research that will help you understand the commonalities, you need to interview people with these experiences using an online survey or questionnaire.

Methods for collecting primary data

The first method is the interview. What are the pros and cons of this type of interview?


  • You will have access to detailed information
  • Abstinence or insincerity can be noticed and noted in your research
  • Ability to control samples


  • Too time-consuming
  • Expensive

Surveys and questionnaires.


  • Participants have a lot to think about when answering
  • Not expensive


  • Multiple missing answers can lead to systematic error
  • Slow



  • All data are objective
  • Does not affect past or future events


    • Information is limited
    • It’s expensive
