A thin client, sometimes called a lean client, is a low-cost, centrally-managed computer devoid of CD-ROM players, diskette drives, and expansion slots. As software as a service ( SaaS) gains popularity, it is expected that thin clients and blade PCs will replace desktop PCs in many work and educational environments. In general, client computers are not as vulnerable to malware attacks, have a longer life cycle, use less power and are less expensive to purchase.
