1. Web Hosting

Web hosting refers to the service of providing the infrastructure, server space, and resources needed to make a website accessible on the internet. It’s like renting space on the internet to store your website’s files and make them available to visitors.

2. Server

A server is a powerful computer that stores and serves web pages and other digital content to users over the internet. When someone visits your website, their device connects to your server to retrieve the web page.

3. Domain Name

Domain Name

A domain name is the human-readable address used to access a website on the internet, such as www.example.com. It provides a user-friendly way to reach websites instead of typing in IP addresses, which are numerical and less intuitive.

4. IP Address

An IP address (Internet Protocol address) is a unique numerical label assigned to each device connected to a computer network, including the internet. IP addresses are used for identifying and locating devices on the web.

5. DNS (Domain Name System)

The DNS is a system that translates human-readable domain names into IP addresses. When you enter a domain name in your browser, the DNS resolves it to the corresponding IP address, allowing your device to connect to the correct server.

14. Uptime

Uptime is the percentage of time a web hosting server is operational and accessible. It’s a measure of server reliability, and higher uptime percentages indicate better server performance.
