#WHAT IS ICAL SERVER HOW TO#
Many people are familiar with how to view and navigate web pages, but have limited knowledge of how those web pages do what they do. If you run a website, it is important to understand what web server is, how does it work, and what role it play in delivering your website content to site visitors. By the end of 1990, the first web page was served on the open internet, and in 1991, people outside of CERN were invited to join this new web community.Īs people began to realize the effectiveness of transferring data across what is now known as the internet, multiple operating systems began to develop so that all could exchange data using computers. In 1989, the first web server, known as CERN httpd, was created with the objective to exchange an information, along with a browser called WorldWideWeb. In this article, we explain what is a web server and how does it work. If the service you're providing becomes popular, a typical computer may not have the necessary resources to handle all of the requests.Web servers are used for hosting websites and data for web applications.Connecting a computer to a network and the Internet can open up your computer to new types of attacks.When your computer is used as a server, its resources (e.g., processing and bandwidth) is taken away from what you have available to do other things.

For example, you could install an FTP server program on your computer to share files between other users on your network.Īlthough it is possible to have your home computer act as a server, keep the following ideas in mind. Any computer, even a home desktop or laptop computer, can act as a server with the right software.
With these types of servers, the hardware is managed by another company and configured remotely by you or your company. Servers that are remote or not hosted on-site are located in a data center. These areas help isolate sensitive computers and equipment from people who should not have access to them. In a business or corporate environment, a server and other network equipment are often stored in a closet or glass house. The domain name can always remain the same, even if the IP address changes. Also, domain names enable the server operator to change the IP address of the server without disrupting the way that users access the server. The domain name makes it easier for users to connect to the server, because the name is easier to remember than an IP address.
When users connect to the domain name (such as ""), the name is automatically translated to the server's IP address by a DNS resolver. Usually, users connect to a server using its domain name, which is registered with a domain name registrar.
The server is assigned an IP address by InterNIC, or by web host. For example, with a web server, a user could connect to the server to view a website, search, and communicate with other users on the network.Īn Internet server works the same way as a local network server, but on a much larger scale. Once connected to the network, other computers can access that server and its features. With a local network, the server connects to a router or switch that all other computers on the network use. How do other computers connect to a server? The following list contains links to various server types. To alleviate these issues, servers are commonly set up to be fault tolerant. Consequently, when servers fail, they can cause the network users and company many problems. Why are servers always on?īecause they are commonly used to deliver services that are constantly required, most servers are never turned off. However, many servers today are shared servers that take on the responsibility of e-mail, DNS, FTP, and even multiple websites in the case of a web server. Some servers are committed to a specific task, often referred to as dedicated. They are also proficient at performing intense calculations. For example, a user may set up a server to control access to a network, send/receive e-mail, manage print jobs, or host a website.
