FAQs About Web Hosting Terms

What is the difference between shared hosting and dedicated hosting?

Shared hosting involves multiple websites sharing the same server resources, making it more affordable but less powerful. Dedicated hosting provides a server exclusively for one website, offering more control, better performance, and higher security, but at a higher cost.

Why is uptime critical for my website?

Uptime is crucial because it determines how often your website is accessible to users. High uptime ensures that your site remains available, essential for maintaining user trust, search engine rankings, and overall site reliability.

What does SSL stand for, and why do I need it?

SSL stands for secure sockets layer. It encrypts data transferred between your website and visitors, protecting sensitive information such as credit card numbers. An SSL certificate also improves SEO rankings and is necessary for eCommerce sites.

How does a CDN improve website performance?

A CDN improves website performance by storing copies of your website’s content on multiple servers worldwide. When a user accesses your site, the CDN delivers the content from the server closest to them, reducing load times and enhancing user experience.

What is the difference between SSL and TLS?

SSL (secure sockets layer) and TLS (transport layer security) are protocols used to encrypt data for secure communication over a network. TLS is the newer, more secure version of SSL and is widely used today in HTTPS connections.

What is a subdomain, and how is it used?

A subdomain is a domain that is part of a larger main domain. It is often used to create distinct sections of a website, such as a blog or store. For example, blog.example.com is a subdomain of example.com.

Why is scalability important for a website?

Scalability is essential because it ensures your website can handle increased traffic and data as your business grows. Scalable hosting solutions like cloud hosting allow you to expand resources without compromising website performance.

What is the role of DNS in web hosting?

DNS (domain name system) translates human-readable domain names into IP addresses, directing users to the correct server where your website is hosted. DNS is essential for routing traffic on the internet and ensuring that users can access your website.

What are the benefits of using a website builder?

Website builders allow users to create professional-looking websites without needing coding skills. They offer customisable templates, drag-and-drop interfaces, and built-in features like SEO tools, making building and launching a website quickly easy.
