WHAT IS RESELLER HOSTING?
Reseller hosting is a form of web hosting wherein the account owner has the ability to use his or her allotted hard drive space and bandwidth to host websites on behalf of third parties. The reseller purchases the host’s services wholesale and then sells them to customers, possibly for a profit. A certain portion of hard drive space and bandwidth is allocated to the reseller account. The reseller may rent a dedicated server from a hosting company, or resell shared hosting services. In the latter case, the reseller is simply given the permission to sell a certain amount of disk space and bandwidth to their own customers without renting a server from a web hosting company they signed for a reseller account with. (wikipedia)

Therefore, the account owner is sort of a hosting service supplier to those end users.ExpertPK
