I have heard terms domain reseller and domain registrar and that domain registrar is better than domain reseller. What is the difference between the two?
Difference between domain reseller and domain registrar?

Registrars are the companies that actually buy licenses to sell TLD's at a registry (those who manage the DNS server for a TLD) such as Verisign for .com. Domain resellers, often hosting companies, resell these TLD's from a registrar as it's much cheaper - otherwise hosting companies would have to buy licenses to sell TLD's themselves, which is extremely expensive.
