A thin client is a computer system used to run applications where most of the actual processing is done on a remote server linked over a network. Biggest Cloud Providers
The local machine, the thin client, is simply used to display the results in a way that is as close as possible to what you might see when running the program locally. These local machines are also called a slim or a lean client.
Thin clients work on an operating system locally and carry flash memory. All applications and data for thin clients are stored in the central server and allows local printing, device support, web browsing, and processing network computing.
The thin client devices used to access remote user data can be strong and operate within a budget for companies that use a thin client. As connection protocols grow and improve, businesses can gain much more effectiveness out of thin clients and virtual desktops.
Client management console is a benefit for thin client users. It is a virtual tool that is installed and remotely manages all deployed employees. A client management console can create, clone, and show the company’s customized image to the deployed thin client devices.
Different thin clients, therefore, support different workloads. For instance, the VNC protocol described above doesn’t (yet) natively support video streams. You could open a video player on a VNC-connected desktop, but you’d see at most one frame every second or so, even on a broadband connection.
On the other hand, you could run a web browser that supports Flash, connect to a remote video server, and enjoy full-screen H.264 video playback — on the exact same network connection. It’s also possible to open a VNC connection in a web browser, since a VNC server can provide a Java-based browser applet that runs at just about the same speed as the binary client and supports most of the same features.

In theory, most any application can be run on a thin client. In practice, getting the most out of a given app in a thin client setting may require functionality that isn’t available through the client device.
Thin clients lend themselves most naturally to certain kinds of usage:
Any place where security is an issue typically benefits from some type of thin-client setup. Data is kept on the backend; the client only presents the user with whatever they are authorized to see, and tampering with the client generally only results in a broken client instead of stolen data.
Thin clients are also useful in public environments — libraries, government offices, airlines, Internet cafés — where many people may use the same machine, and there’s a need to reduce the amount of risk due to leftover data from previous sessions. The risk is not eliminated — it’s always possible to “shoulder-surf” someone else’s work — but it is reduced by dint of there being minimal data on the terminal itself.

Thin clients are well-suited to workloads where the actual work being done is not CPU-intensive, and requires only as much client feedback as would be provided by a web browser. In fact, many such thin clients may well be web browsers, since they provide toolsets to cover most of the user interaction you might need in such a scenario.
One common scenario for repurposing older PC hardware is to convert it into a thin-client system of some kind. Applications that would not run well on the PC itself could be published from a server to that PC across a thin-client connection, provided the app’s functionality wouldn’t be hindered that way.

Thin clients can be grouped into two basic categories: software thin clients and hardware thin clients.
A hardware thin client is a device that has been created specifically to run thin-client software and little else. It’s easy to compare it with the “dumb terminal” or “diskless workstation” of old, albeit with better graphics, but there are some other differences.
For one, the exact makeup of a hardware thin client varies. It could be an existing PC that’s been stripped down to do nothing more than run the client software, or a custom-designed piece of hardware that again does little more than connect to the remote host and perform the needed client display functions. One example of such a device is the nComputing system, a hardware thin-client mated with a server which allows dozens of users to be supported by a single desktop-class machine.
A software thin client is, simply, an application running on whatever host is available, whether dedicated (as with a hardware client) or just commodity hardware. It may use some of the abilities of the local host — hardware-based graphics acceleration, for instance — to better render the remote client’s interface.
But the exact choice of host doesn’t have to be a system designed solely as a connecting client—it can be a full-blown PC with its own workload, running the thin-client application in conjunction with other things.
Provided is hardware thin clients and software thin client software examples:
The single biggest disadvantage to a thin client is its dependency on the network. Since everything a thin client does is provided across a network connection, the network becomes both a single point of failure and the single biggest performance bottleneck in the system. If the network slows down, experiences latency or cuts out completely, the client may do anything from lag to stop working entirely.
The exact construction of the thin client and server model in question can ameliorate some of the problems with a slow or flaky network. A web browser, for instance, can locally cache everything it downloads, although the size of the cache will vary depending on the capacity of the client hardware. Most anyone who’s browsed from their cache during a DNS outage will be familiar with how useful this can be.
However, thin client dependency on the network remains. Also, networks are still many orders of magnitude slower than the slowest internal component in even a modest PC— the cost of which may be comparable to a hardware thin client. This may limit a thin client’s cost-effectiveness compared to a more conventional local-workstation solution.
A thin client is a computer system used to run applications where most processing is done on a remote server linked over a network, grouped into two basic categories: software thin clients and hardware thin clients.
All applications and data for thin clients are stored in the central server and allows local printing, device support, web browsing, and processing network computing. Thin clients are great for high-security and public environments, minimal workload, and higher computational demand for apps.
