Outside the computer community, most people have a lack of knowledge of basic technical concepts and specific terms. The difference between a server and a web host is a good example. There is confusion between these two ideas and how they relate to each other. Without a server and without a web host , the Internet would stop working. The following points should clear up misunderstandings and help you understand how these elements work and interact.
What are servers and web hosts?
Let's start by explaining what servers and web hosts are. In general, a Web server is an entity that accepts requests via HTTP or a similar protocol and generates a response. It can be either numeric in the case of the Apache web server program, or physical, as a dedicated machine equipped with the aforementioned program. Web hosting is a service sold by specific companies called "hosters". They rent their servers to their customers, allowing them to create their websites.
Explanation of basic features
Whether physical or purely software, a server receives data and performs operations before returning their results to clients. For example, an Apache server receives a request from a web browser, calls its associated database, and then fills an HTML file with the generated information. A web host uses multiple network devices, such as switches or routers, to relay information from servers and to servers.
Web hosts store multiple servers in "Datacenters" or data centers and manage hardware and software for their customers.
Hardware vs Software
A physical server is simply a computer without a monitor. It includes a processor, a motherboard, RAM and several hard drives storing data. Servers usually look like VCRs stored on top of one another in racks. This allows the host to save space and simplify management and maintenance. A Web server program such as Apache, Nginx, or IIS performs the operations required to run a site. You will need both to make your site visible on the Web.
The network aspect
In the end, a server that is not accessible from the outside will not be very useful. Web hosts connect through Internet service providers in the same way as the average consumer. The only real difference is the bandwidth. Web hosts can support download and upload speeds in the terabit per second range. An average web host uses a variety of DNS and BGP servers configured specifically to provide communication between sites and servers across the internet.
Why do we pay for accommodation?
In theory, it is possible to host your home site using a standard PC. However, the vast majority of sites reside on servers within data centers. This is because web hosts have more powerful hardware than generic consumer PCs. In addition, hosts have specialized network equipment such as high-speed fiber optic cables that can support a huge data load. Finally, the hosts repair or replace the machines as they break down and are vigilant on everything related to firewall or malware problems.
Where to go?
When you go looking for a web server, power and speed are the most critical aspects. The amount of RAM and the power of your dot processor you will need depend on the size of your site and the traffic it generates. A good host is reliable and secure. You prefer a web host that guarantees 99.99% connection time and strict security measures. Quality hosters tend to have quality software and server hardware. Do your research before you engage with a hosting company.
