To understand how a website works, we need to find out what components the website includes and the tools / media that help it work.

History of Website

Web created by Tim Berners-Lee, a computer scientist in 1989, in a laboratory in Geneva, Switzerland. He has devised a method to navigate between files using:  Hyper link Frame work (HTTP).  Hyper Text Mark up Language (HTML).  Web browser and web server.

Web server

 Web server: A place to store source code and website content;  The web server is identified by its IP address;  Web servers (private) are usually for large websites, small and medium websites often use a small portion of the web server's resources.

Web Page Addresses (URLs)

The URL is simply a link to the website, referring to resources on the internet. The use of these resources requires the correct links and the URL for this task. The URL stands for Uniform Resource Locator, which replaces IP addresses, making it possible for computers to communicate with servers and server systems. URLs help determine the structure of the file on certain websites.

How to find out the website?

1 - Enter IP Address Enter the Apple server's IP address such as: 70.73.176. 2 - Enter URL Enter the correct Apple URL: www.apple.com 3 – Search by name You can search the website by the name of the site. Enter the website name as "Apple

Domain name system (DNS)

 Domain name is an alternate name for the IP address of the web server,  The assignment (mapping) of domain names to IP addresses is done by the domain name resolution system (DNS).

How domain names are organized and

managed

The Domain Name System is a hierarchical system, and at the top of the hierarchy is the DNS root zone. ICANN assigns organizations to manage Top Level Domains (such as the com domain) and accredits registrars who buy and manage namespace -- on behalf of companies and individuals -- within these Top-Level Domains The top-level domains use across the Internet were: .com - Commercial organizations .edu - Universities and other educational institutions The administration of domains may be devolved to sub-domains to assign a unique name to a particular department, function, or service related to the organization, etc.

Registration a Domain & Host

Step 1: Create a basic web page with Sublime Text 3, use HTML language to design the web. Step 2: Access infinityfree.net, this is a Free Unlimited Web Hosting. Upload the html file and save it

Types of DNS servers and their roles

Root Name Servers: The root server represents the top level of the DNS hierarchy. Local Name Servers: Local servers represent the lowest level DNS servers owned and maintained by many business organizations and Internet service providers (ISPs)

Purpose of DNS

The main purpose of DNS is to provide mapping between symbolic names and IP addresses in a worldwide hierarchical and hierarchical database.

Communication protocols

 It is a set of standard rules for data representation, signaling, authentication and error detection  There are several protocols used to communicate or convey information on the Internet: TCP, IP, HTTP, FTP, SMTP, POP ..

Server hardware

 Server Hardware means Computer Hardware which operates in a local area network that runs administrative software which controls access to all or part of the network and its resources and makes such resources available to computers acting as workstations on the network.
