Client-Server communication model is one of the most common Internet communication models. This model describes the relationship between two computer programs.
One of them calls a client who claims a service, information or resource from another program we call a server – he, in turn, processes and executes the request by providing the requested resource. Programs can run on the same computer or be on separate machines, in which case communication takes place over the network. Which program is a client and which server is determined by what role it performs. If a service/resource is a server, and if it is a consumer we call it a client.
How does this work?
When we want to open a page, we enter the address in your browser (this is the client). It analyzes the entered URL and derives information about where to send the request and what protocol. It then sends the request to the machine on which the desired page is stored. On this machine runs a program – a web server that is constantly waiting for client queries. When our query reaches the web server, it also analyzes the URL and retrieves information about exactly what content is required (page, action, video, etc.) and where it is stored. Once these things have been established, the content is sent to the client. When the browser gets it, it displays it on the screen, of course, formatting it according to its type and other factors.
What are web Dedicated Servers?
Web Dedicated Servers are computer programs that deliver different types of content to the end user, such as web pages, using the HTTP protocol on the global www space. By Web Server we mean the software that performs this function. Examples of popular web servers are Apache, IIS, nginx, Google Web Server (GWS), and more. Otherwise, the term web server is often used for the physical server itself, on which the software works, referring to the role it performs.
What is the main function of the web server?
The main function of the web server is to store the content of web pages, web applications, etc., to receive and process queries coming from clients (browsers) and to respond to these requests by sending the relevant content to the client. As technology evolves, the content of web pages is becoming more and more diverse and thus extends the features and capabilities of web servers. If ever, their features were limited to providing text and images on demand, they are now used to store and service all kinds of sophisticated applications such as web services, control panels, social media, and more.
What is the root protocol the web server works with?
The basic protocol through which queries are received and the content is sent is called HTTP – Hypertext Transfer Protocol, and the basic format of web pages is HTML – Hypertext Markup Language.
Top Web Servers:
There are many web servers, but those that are widely used are a few. It is almost certain that when you open a page, the content is delivered to you via one of the following servers:
– Microsoft IIS
– Google Web Server (GWS)
Web server as a service
Like any program, web servers have certain environmental requirements, but they can also run on any available computer. However, when we want a website to be accessible to a wide audience without interruption, then the task is no longer that simple. In many cases, websites are an important part of a business and a source of funds. This places higher requirements on their hosting.
Continuous power supply, constant Internet connection, technical support, security, and monitoring must be provided to ensure that their content is available at all times. For this reason, websites and web servers, respectively, work on server hardware, in special collocation centers, where the necessary conditions are provided to maintain the quality of the service. The web servers themselves, like software, have many features and require setup and care. This is the task of hosting companies like WebHostFace – to provide optimal conditions for storing and servicing web content. If it’s a commercial site with thousands of visits per day, it’s not possible to maintain it at home on your own computer. That is why sites are massively stored and serviced by hosting companies that have the necessary experience and the necessary conditions for the purpose.
