Michael Dell, a student at the University of Texas, started the brand of Dell in 1984 as a computer maintenance company. Michael Dell started the company also because IBM PC compatibles are standardized to component level and the fact that anyone can manufacture IBM compatible personal computers, and thus starts manufacturing and selling PCs. Dell features a direct-to-consumer (DTC) sales style that eliminates middlemen and has no inventory. It offers the latest spec PCs and other products at a low price, and allows you to purchase PCs with the specs you want (models that can be taken home on the spot are also available). Currently, sales volume is top class in the world. Since 2008, the company has been committed to acquiring IT solutions and researching and developing enterprise solutions with a total investment of approximately $ 18 billion. This will enable the company to become a comprehensive IT company that handles not only endpoints such as PCs and tablets, but also hardware such as servers, storage, and networks that form the foundation of datacenters, as well as software for IT infrastructure, big data analysis software, and security solutions. In October 2013, Michael Dell, Chairman and CEO, and global investment firm Silver Lake completed the delisting of Dell.
