Understanding How Web Hosting Works

Web hosting is a service that allows organizations and individuals to post a website or web page onto the Internet. A web host, or web hosting service provider, is a business that provides the technologies and services needed for the website or webpage to be viewed on the Internet. Websites are hosted or stored on special computers called servers. When Internet users want to view your website, they must type your website address or domain into their browser. Their computer will then connect to your server, and your web pages will be delivered through the browser.


Web Hosting Servers

Web hosting servers are special computers that store websites and make them accessible to Internet users. When you create a website, you need to store it on a web hosting server so people can access it when they type your domain name into their browser. There are two types of web hosting servers: shared and dedicated.

Shared servers are where your website shares space with other websites on the same server. This is the most common type of web hosting, and it’s usually the most affordable option. The dedicated hosting servers are where your website has its own space on a server. This is more expensive than shared hosting, but it gives you more control over your website since you’re not sharing resources with other websites.

Web Hosting Services

Many types of web hosting services are available, but the two main categories are self-managed and managed.

Self-managed hosting gives you full control over your server, but it also requires you to handle all of the technical aspects of running a server yourself. This includes installing software, setting up security, and keeping your server up-to-date.

Managed hosting takes care of all the technical aspects of running a server for you, so you don’t have to worry about it. This is more expensive than self-managed hosting, but it’s a good option if you’re not comfortable with managing a server yourself.

Web Hosting Plans

Many types of web hosting plans are available, but the three most common are shared, virtual private server (VPS), and dedicated.

Shared plans are the most affordable, but they also offer the least resources since your website shares space with other websites on the same server.

Virtual private servers (VPS) offer more resources than shared plans but are still more affordable than dedicated plans.

Dedicated plans offer the most resources but are also the most expensive.

Domain Name System

The Domain Name System (DNS) is like a phone book for the Internet. It’s a distributed database containing records of all the public websites. When you type a website address into your browser, DNS translates that address into a series of numbers called an IP address and then connects you to the correct website.

Every device on the Internet has a unique IP address, a series of numbers. For example, the IP address for Google is 74.125.224.72. Websites also have IP addresses, but they’re much easier to remember if they have a name like www.google.com instead of an IP address like 74.125.224.72. That’s where DNS comes in – it associates easy-to-remember domain names with the numerical IP addresses of websites, so we don’t have to keep track of all those numbers ourselves.

How DNS Works

When you type a website address into your browser, the first thing that happens is a DNS lookup. Your computer contacts a DNS server and asks it for the IP address associated with the domain name you’re trying to visit. The DNS server then looks up the IP address in its database and responds to your computer. Once it has the IP address, your computer can connect to the correct website.

DNS servers are organized in a hierarchy, with each level containing records for a specific part of the namespace. For example, root servers at the top of the hierarchy contain records for all top-level domains like .com, .net, and .org. There are also authoritative DNS servers that contain records for specific domain names.

When you type a domain name into your browser, your computer will first contact a root server to get the IP address of an authoritative DNS server for that domain. It will then contact the authoritative DNS server to get the IP address of the website you’re trying to visit. Finally, it will connect to the correct website using its received IP address.
