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. The term derives from the fact that small computers in networks tend to be clients and not servers. Since the idea is to limit the capabilities of these computers to only essential applications, they tend to be purchased and remain “thin” in terms of the client applications they include. 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, they are not as vulnerable to malware attacks, have a longer life cycle, use less power and are less expensive to purchase. Thin client is also used to describe software applications that use the client-server model where the server performs all the processing.
Secure Computing : Protect your data with unique security features.
HP Thin Clients are nothing more than paperweights when not connected to a secure network. That’s right. Once unplugged from the HP high-security environment, absolutely
no data can be found. HP Thin Clients also include unique security features like Enhanced or File-based Write Filters and built-in firewalls. Control and customize end-user network access like never before with antivirus software and support for multi-factor authentication through smart cards.
Manageability : Manageability for control freaks.
We’re control freaks, too. That’s why we keep management centralized at the server in the datacenter. That way, there are fewer points of failure and less susceptibility to viruses and malware. And thin clients are easy to deploy—out of the box in less than 10 minutes—with configuration that’s as real no-brainer. All it takes is a web browser or remote desktop software to connect thin clients to your server.
High Performance :Accommodate all types of users.
All user types are accommodated with thin computing solutions from HP— including power 
users in fields like design, manufacturing, oil and gas exploration, or financial services who need greater performance, specialized USB hardware, and advanced, 2D, 3D, and multimedia application support. Customized applications and USB device support are no problem.
