Introduction
The Internet is a complex network based on numerous technical concepts and terms. For website operators, webmasters and all those who deal with the topic of web hosting in Germany or internationally, it is essential to know and understand the basic technical terms. A thorough understanding of these terms not only makes it easier to choose the right web hosting provider, but also to effectively manage and optimize your online presence. In this comprehensive web hosting glossary, we explain 50 of the most important terms you should know in order to navigate the web hosting sector with confidence and run your website successfully.
Basic web hosting terms
1. web hosting
Web hosting refers to the provision of storage space and necessary resources on a server to make a website accessible on the internet. It is an essential service for anyone who wants to establish an online presence, be it for personal blogs, company websites or e-commerce platforms. Cheap web hosting often offers different packages tailored to the different needs of website owners.
2nd domain
A domain is the unique address of a website on the Internet, such as "www.example.com". It serves as an easily recognizable alternative to the IP address and is an important part of any website. Choosing a good domain is crucial for branding and the findability of your website in search engines.
3. server
A server is a powerful computer that provides data and services for other computers (clients) in the network. In the context of web hosting, the server stores and manages the files and databases of a website. The quality and capacity of the server directly influence the performance and availability of your website.
4th IP address
An IP address is a unique numerical identifier that is assigned to every device on the Internet. It enables communication between different devices on the network. For websites, the IP address is important for assigning the domain to the corresponding server on which the website is hosted.
5. DNS (Domain Name System)
The DNS is like a telephone directory of the internet. It translates domain names into IP addresses, allowing users to access websites using easy-to-remember names instead of complicated number combinations. A correctly configured DNS is crucial for the accessibility and loading speed of your website.
Hosting types and technologies
6. shared hosting
With shared hosting, several websites share the resources of one server. It is a cost-effective option for smaller websites with lower traffic volumes. Despite the shared resources, shared hosting often offers sufficient performance for personal blogs, small businesses and start-ups.
7 VPS (Virtual Private Server)
A VPS is a virtual server that shares the resources of a physical server with other VPSs, but has its own dedicated resources. It offers more control and performance than shared hosting and is well suited for medium-sized websites or applications that require more flexibility and security.
8. dedicated server
A dedicated server is a physical server that is reserved exclusively for a website or organization. It offers maximum control, performance and security, ideal for large companies, e-commerce platforms and websites with high traffic volumes.
9. cloud hosting
Cloud hosting uses a network of connected servers to provide resources flexibly. It enables high scalability and reliability as the website content is distributed across multiple servers. This type of hosting is ideal for websites with variable traffic volumes and for companies that require high availability.
10. managed hosting
With managed hosting, the hosting provider takes over technical tasks such as updates, security and backups, which reduces the administrative burden for the customer. This is particularly advantageous for companies that want to concentrate on their core competencies without having to worry about the technical administration of their web server.
Web hosting resources and performance
11th bandwidth
Bandwidth refers to the amount of data that can be transferred in a certain amount of time. It is an important factor for the loading speed and performance of a website. Sufficient bandwidth ensures that your website loads quickly and reliably even with high traffic volumes.
12. storage space
The storage space indicates how much space is available on the server for files, databases and emails. Depending on the type and size of your website, you may need more or less storage space. Modern web hosting providers often offer scalable storage options to meet the growing requirements of your website.
13. CPU
The CPU (Central Processing Unit) is the "brain" of the server and processes all requests and calculations. A powerful CPU ensures faster data processing and improves the overall performance of your website, especially with dynamic content and applications.
14. RAM
RAM (Random Access Memory) is the working memory of the server and has a significant influence on speed and performance. More RAM enables the server to handle more processes simultaneously, which shortens loading times and improves the user experience.
15. uptime
Uptime is the time during which a server or website is available without interruption. A high uptime of 99.9% or more is crucial for the reliability of a hosting service and ensures that your website is always available.
Security and data protection
16. SSL/TLS
SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are protocols for encrypting data transmissions on the internet. An SSL certificate secures the communication between your web server and the visitors to your website, which not only increases security, but also strengthens user trust and has a positive effect on SEO rankings.
17. firewall
A firewall is a security system that monitors incoming and outgoing network traffic and blocks unwanted access. It protects your website from potential threats such as hacking attacks, malware and other security risks.
18. backup
A backup is a backup copy of data that can be restored in the event of data loss or corruption. Regular backups are essential to ensure the integrity and availability of your website data and to enable quick restores in an emergency.
19 DDoS protection
DDoS (Distributed Denial of Service) protection refers to measures to defend against attacks that aim to overload a server or website with a flood of requests. Effective DDoS protection ensures that your website remains accessible even in the event of targeted attacks and that business continuity is maintained.
20. two-factor authentication (2FA)
2FA is an additional level of security that requires a second factor for authentication in addition to the password, e.g. a code on the smartphone. This significantly reduces the risk of unauthorized access and protects sensitive data and administrative access to your website.
