Your computer is compatible only with certain web site programming languages. When you visit different web hosts, you will see the variety of programming languages that that web host offers. Unless a web host uses a programming language that can be used by your computer, their services are useless to you.
Computer Specifications and Operating System
You will need to know the specifications and operating system of your computer in order to know which web site programming languages are compatible with your computer. Do a web search using keywords that include your operating system, computer specs and "web host languages". You should come up with articles, discussions and other resources that will allow you to quickly identify which programming languages can operate with your computer. This will help you weed out the web host services that you cannot use.
