[Overview] What Is a Thin Client & Its Pros/Cons and Examples? [MiniTool Wiki]
Thin Client Definition
What Is a Thin Client?
In computer networking, a thin client is a simple low-performance computer that has been optimized for building a remote connection with a server-based computing environment. Within this environment, the server handles most of the work including opening applications, performing calculations, as well as saving data.
Thin client computers play as components of a broader computing infrastructure, where a lot of clients share their computations with a server or server farm. The server-side infrastructure makes use of cloud computing programs like hosted shared desktop (HSD), virtual desktop infrastructure (VDI), and app virtualization.
Thin client hardware generally supports common peripherals including monitors, keyboards, mice, open ports for USB devices (such as flash drive, printers, and webcams), as well as jacks for sound peripherals.
Some thin client PCs consist of (legacy) serial or parallel ports to support older devices like time clocks, receipt printers, or scales. Typically, thin client software includes cloud access agents (like ICA, RDP, or PCoIP), a graphical user interface (GUI), a local web browser, terminal emulators (for some situations), and a basic set of local utilities.
- ICA refers to independent computing architecture.
- PCoIP means PC over IP, a proprietary remote display protocol (RDP) by Teradici company.
Thin Client OS
A Thin client OS is an operating system that powers a thin client, enabling the device to run.
Advantages of Using Thin Client Technology
The thin client combination forms what is called a cloud-based system, where desktop resources are centralized at at least one data center. This centralization brings some benefits such as optimization of hardware, reduced software management, and improved data security.
1. Hardware Resource Optimization
Taking advantage of the thin client methodology optimizes the usage of the hardware equipment within the system. For example, bussing, input/output (I/O), and cabling can be minimized while idle memory and processing power can be assigned to user sessions where need those resources most.
2. Software Maintenance Simplification
With the thin client deployment, software patching and OS migration can be applied, tested, and activated for all users in one instance to accelerate roll-out and improve administrative efficiency thus reducing the cost to run the whole system.
3. Security Improvement
Within the thin client setup, software assets are centralized and are easily monitored and protected by firewalls. The sensitive data is uncompromised in case of device loss.
Disadvantages of Thin Client Technology
Thin clients have many advantages including the above one. Yet, they still have some limitations.
- Thin clients are extremely dependent on a continuous Internet connection.
- Slower network than relying on internal computer components.
- Servers have to be sized correctly to deliver the right amount of resources to each client.
Think Client vs Thin Client
In contrast with the thin client, there is a thick client (also called fat client, rich client, or heavy client) or a conventional PC. A thick client also aims to work in a client-server model yet has significant local processing power. However, a conventional personal computer intends to carry out its functions mostly locally.
