What’s the use of www. and. com in websites? As an extension of the question, why do emails have. Com too?
In: Technology
.com is a Top Level Domain. Any Internet address ending with .com must be registered with a central authority responsible for .com addresses.
Other Top Level Domains are .gov (for US government agencies), .uk (for addresses in the United Kingdom), and .mil (for the US military). Splitting up the domains this way allows different entities to decide how to use their block off internet domain names.
Google.com is the internet domain registered to Google.
Www is *not* part of the publicly registered address. It is a name the site administrator picked for a machine or service at an internet site. On a small network, the admin might direct users to login to mail.website.com for email and www.website.com for the web site and these will actually go to different places. A lot of times, however, the administrator will just send everyone to website.com and let the protocol determine whether to go to email, website, or wherever.
