Client Side

Client Side:-

In Client side we usually use “Thin Client “(or Low Powered PC).

Thin Client:-

Thin Client is a low-cost computing device that works in an application server environment. It does not require state-of-the art, powerful processors and large amounts of RAM and ROM. A Thin Client environment also provides assurance for disaster recovery and business continuity as users applications, and configurations are stored on centrally-managed servers with backups.

*Internet2/Cloud May be a server (Virtualized) or Group of Server (Computer Grid)

• A Hardware/Software that runs application on a server, not on desktop.
• Key strokes and mouse click are sent over network to the server to process and give back the result…… (Screen).
• Clients can be a low powered PC or a Thin client device.
• They Don’t Have HDD, FDD, CDROMS, Cooling Fans, Very Low Processing Power.

Note:-

· Client: - is a computing device/software that retrieves information from a server.

· Thick Client: - is a computing device that includes a software operating system, a powerful processor and a wide range of applications that can execute on the computing device.

Advantages of Thin Client:-

· Dramatically Decreases The TCO by 54% to 57%.

· Decreases IT Cost By 80% through Reduced Staff And Centralized Software Management. Greatly Simplifies The Software Upgrade Over The Network.

· Eliminates The Hardware Upgrades On Client Side.

· Increases End User Productivity. (Limited Access To Authorized Applications & Storage)

· Increased Life Time Of Client. (NO Moving Part ,Less Power Usage)

· Provides Higher Security. (Authentication, virus protection, data on server, theft).

· No Access To HDD, FDD, CD-ROMS. (Avoids Downloads, installations, Junk Data on to the HDD)

· Reduced Power Consumption.

· Centralized Backup. (Home Directory Mapping)

· Simplifies infrastructure

· 286,386,486 PCs Can Be Converted To Thin Client And Can Work At Speed Of 800Mz Celeron Processor.

Disadvantages of Thin Client:-

• Entry costs are high for servers and installation expertise.
• More bandwidth is required; multimedia, project-based learning applications run very slowly.
• Thin-client doesn’t allow the flexibility to load software on the spot
• PC’s are coming down in costs, and many educators believe users need the fully-functioning capabilities of a desktop.

Thin Clients reduce costs by requiring only a low-cost display unit on each desk, while a server cluster provides the actual computing horsepower. This allows streamlined, centralized management of a large number of desktops, rather than maintaining hardware and software on each individual workstation.
