With thin-client computing, implementation of the Linux operating system (OS) in the enterprise is faster. The server-centered approach, with thin computing attached for the desktop, offers a 'much more versatile, cost-effective, secure, and manageable IT environment.' Linux thin clients now represent over one-fifth of the current market globally for thin clients and are becoming more attractive as companies try to reduce costs and fulfill Linux mandates. Thin clients can run the most advanced Web, Windows-based, and Linux applications in a seasoned architecture that increases security, manageability, affordability, and reliability in a client/server architecture. In such an environment, data and applications reside on PCs throughout an organization. In the open source environment, Linux thin clients are designed to run in a mixed-OS environment that runs multiple applications concurrently. Linux thin clients can serve up Windows, Linux, Java, text-based, or browser-based applications. The client is manageable to an extent unlike any other desktop Linux configurations. The most significant benefit of a thin Linux configure may be in the area of security. While Linux desktop PCs run multiple network services and local applications that can be exposed to viruses, attacks, and security intrusions, Linux thin clients do not store applications with openings at the desktop. Linux thin clients are also 'locked-down,' with no floppy drives, extra peripherals, or software downloads. Thin clients also are more reliable because they do not have moving parts. Open Source Development Labs (OSDL) divides desktop usage into five groups (transactions workers, technical workstations, basic knowledge workers, advanced knowledge workers, and kiosks). Some users may prefer other architectures, but thin clients support the needs of most business users very affordably, reliably, and securely.
