The system by which Internet domain names and addresses are tracked and regulated.

Yes. You can register domain names before you find a hosting provider, and, in fact, you are not required to host a domain name. When you register a domain name with us, we automatically park it.

A temporary, parked page displays when visitors type the domain name into their browser's address bar. The parked page indicates you are reserving the site also we offer free 2 email accounts with every domain.

TLD is an abbreviation for top level domain. A TLD is the extension or portion of a domain name that follows the dot(or period). You are likely most familiar with TLDs like .com, .net, .biz, .info and .org. These TLDs are designed to signify something relevant to the domain. For example, the .com TLD stands for "commercial" while .net stands for "network".
There is also an option called a ccTLD, or a country code top-level domain. A ccTLD is designed to signify sites located in or associated with certain countries or territories. However, most of the ccTLD options don't actually have restrictions regarding who can register a domain name. In fact, many ccTLDs are commonly misinterpreted as TLDs. For example, while .tv is commonly registered by television and media related websites, .tv is actually the ccTLD designated for the country of Tuvalu.
There are also second level domain options too, particularly popular with ccTLDs. For example, the United Kingdom has a number of second level domains ranging from '.co.uk' (designed for United Kingdom based businesses) to '.net.uk' (designed for UK-based internet providers).
Domain hacks are also a popular use of both TLDs and ccTLDs. A domain hack involves creating a full word or phrase when combining the domain name with the TLD to create something your audience will easily remember. A popular example is using the .me ccTLD for Montenegro, and combining it with "aweso" to create the domain aweso.me.

DNS is an abbreviation for domain name system. The domain name system is like the phone book for the internet.
DNS is essentially a database of IP addresses. Each IP address contains a series of numbers that allow computers to communicate with each other. A website is identified on a server by its IP address. Instead of your visitors having to remember an IP address to type into their browser to access your site, they can instead just use your more memorable domain name. When your domain is entered into the browser, DNS translates it into an IP address because that is what computers understand. Your computer is able to connect to your domain hosting and show your website on the web browser once the IP address is found.

A domain name registration is the simple process of reserving your website's name for a specified period of time. The two parties involved with a domain registration are generally the user who is registering the domain and the domain registrar. The domain registrant is the user who actually registers the domain name (you) and the domain registrar is the company who helps that user with their domain registration (OBHost).

When you register domain names from OBHost, you get access to our user-friendly MyOBHost control panel. You can manage your domains and all of the features included with your OBHost domain registration in this control panel. Just some of the domain features you’ll be able to manage include customizing your nameservers, transfer in a new domain, DNS and much more!

Yes, you need web hosting to have a website.
You can have a domain name. You can have domain hosting (AKA web hosting). But without the two together, you're not going to be able to have a website. Domain names and domain hosting are attached at the hip.
When you register a domain name, you are acquiring exclusive access for your visitors to use that web address to find you online. But if you want to actually put up a website at that address, you need domain hosting. Domain hosting is the service used to store all of the files that make up your website.
Think of domain names and domain hosting as a physical storefront. A domain name is like renting an address for a plot of land. It's your plot of land for as long as you keep paying your rent. At the end of the day though, it's still just a plot of land. You still need walls, windows, doors and a roof for your store. These are the files, databases, images and videos that your website consists of. This is your domain hosting. Without domain hosting, you can't have a website.
At OBHost, we offer both domain name registration and domain hosting! Simplify the administration of your website by having both all in a single location!
