What is Domain? Why it is used for? Certainly, it is only for new, actually it is for them who don’t know it.
“Domain” is an English word which means “place”. If you want to open a web site, then you have to buy one place or Domain from a reputed organization. If someone wants to come into your office, then they have to know its address. This address is a name which is called a domain name for a web site. This domain name also will identify your website in different ways. Like, you know every man has a name. They carry their identity with their names. A domain also is a name like the almost man’s name. The difference between domain name and the man’s name is that the man’s name is not unique, it means many people have the same name. But, domain name is a totally unique, it means there are no second place for domain in the world. You can see your mobile number as right example. There is no visibility of anyone’s number with your phone number. A domain is an address of the website through which user will find this web site. Like you can see one domain name which is http://www.thementalclub.com. Using IP address in spite of domain You can also enter in your web site or visit any website. Generally IP address is in numbers. Like 10.196.001.002 is an IP address.
