Michael Dell started Dell Computers in 1984 from his dorm room at the University of Texas at Austin. Dell began by selling assembled personal computers directly to customers, providing customization and low prices. This business model was highly successful and helped Dell grow into one of the largest technology companies in the world, selling PCs, servers, networking products, and mobile devices like the Dell Streak tablet. Dell is now headquartered in Round Rock, Texas and employs over 103,000 people worldwide.
