The domain is the address of our website. To understand more clearly if I ask you where the Eiffel tower is located you will tell me that it is located in Paris, France while if you will ask me what your domain is I will tell you it is old.eltonheta.com so the domain is our internet address.
What does a domain consist ofc?
A domain has a name and a suffix, so in my case the name is “eltonheta” and the suffix is ”.tech”
The suffix has a certain meaning, for example .org is used by organizations, .edu is used by educational centers such as universities, etc., .gov is used by state institutions, etc.
What is hidden behind a domain?
An IP is always hidden behind a domain, for example behind Google.com is the IP of the google server which is 142.251.41.14 but varies from case to case for security reasons.
I hope this material has helped you and I am clear in what I have expressed.
You will find other materials here so remember this domain if you opened it by accident.
