What Are Web Servers? Why Are They Necessary?

The first versions of WWW ((what most people call “The Web”))) provide means for people around the world to exchange information between, to work together, to communicate, and to share documentation more efficiently. Tim Berners-Lee wrote the first browser (called WWW browser) and Web server in March 1991, allowing hypertext documents to be stored, fetched, and viewed. The Web can be seen as a tremendous document store where these documents (web pages) can be fetched by typing their address into a web browser. To do that, two im- portant techniques have been developed. First, a language called Hypertext Markup Languag (HTML) tells the computers how to display documents which contain texts, photos, sounds, visuals (video), and animation, interactive

A web server is a PC that opens pages on a browser on request. It sends the web address of the page that has been requested to the web browser. They have an IP address and possibly domains and are essential for an ecommerce because ecommerce is online and a web server is what you need to surf the web.

Web hosting services – this is where a user will buy a certain amount of storage space on a company’s network, which will then be visible to the public through a IP address, and store their website files so a third user can visit the website. This allows users to view the website by downloading packets of information.

As a conclusion, Lighttpd is a high-quality web server that suitable for any websites with dynamic content. It is also an alternative web server which is easy to configure and efficient than the resource limited web servers.

Web Server: A webserver is a Hardware device used to host an eCommerce website. The server supports the entire content of the website such as HTML files, Data bases and Image Files. Web Servers will run on operating systems such as Windows or Linux and will use web server software to manage access requests to the website. Webservers are similar to PC’s however they have faster processors and more memory making it much more powerful.

Server: This is a computer that is designed to carry out specific functions at the request of other computers they’re connected to a network and direct the information stored on the network to clients, for example a web server will run software that receives requests from clients and then processes the request and delivers an output using HTML.

Web application is the communication between client and server using HTTP protocol. Where the server is responsible for serving web pages. Client which is web browser, request web page from the server, receive the server response and display to the user. The user uses the client (web browser) to display the web pages, watch videos online etc. The client side and server side programming refers to the programming which runs at the specific side, the server’s or the client’s.

A web server is computers otherwise gathering of computers that are used to deliver a web pages and other information to multiple users within the server.

SYN-ACT is the Web server communication whereas each conversation begins with a sequence of “handshake” interaction. The computer system will initiate to send information to synchronize in the web server. The contacted Web server responds with a synchronized acknowledge or “SYN-ACT”

Since shared data is in one location, it is easy to back up critical information. Though the server-based network demonstrates better performance and data handling, it is important to know that when the server goes down it takes the entire network with it. Unlike peer-to-peer networks server-based networks are more secure because security is handled for the network as a whole and not just for individual computers. Owing to these benefits, server-based systems are extensively used by large businesses and for various web

Application servers: These servers use special tags within an HTML file to direct processing. They also can have hooks to call external programs to handle processing that is not built into the server, and they also separate developer and server portions into separate packages.

The address of a web server can be easily retrieved on Wireshark by looking at the “Destination” tab. Also, I could open command prompt and ping the entire domain and receive the IP address in relation to it. Therefore, the IP address of the “gaia.cs.umass.edu” server is 128.119.245.12. See Figures 9 and 10.

A server is a node on the network that provides services to the users of that network. A server will manage hardware and software resources or monitor the exchange of information through a network. Each server will respond to the requests of a user and provide a service, like printing a document or retrieving a stored file. There are two basic types of servers: Dedicated and Non-dedicated.

Internet Servers (also commonly known as Web Servers), primarily function to deliver web pages on request to clients. When a user types a domain name into their browser, or clicks on a link, the request is first sent to a Domain Name Server (DNS). DNSs are servers that hold databases full of domain names and IP addresses. When a DNS receives a request, it matches the domain name (ie, www.CriketX.com) to the IP address of the server that holds all of the files that make up that particular website and sends that information back to the user’s browser. The browser can then send a request for those files to the IP address of the web server (205.134.224.227 for www.CriketX.com). If

Computers (and other network devices like smartphones or tablets) use IP addresses to identify each other on the network and route your request to the site you are trying to access. It is just like dialing a phone number to reach the person you want to talk to, but thanks to DNS, you don’t need to maintain your own address book of IP addresses. You will simply connect via DNS server (also called “domain name server” or just “name server”). Domain name system servers match domain names like coursera.org to their associated IP addresses.
