I. Server Concept
A server is a type of computer that runs faster, handles higher loads, and is more expensive than a regular computer. Servers provide computing or application services to other client machines (such as PCs, smartphones, ATMs, and other terminal devices) on a network. Servers feature high-speed CPU processing power, long-term reliable operation, powerful I/O external data throughput capabilities, and better scalability.
Server Classification
There are many types of servers, the most common being tower servers, rack servers, and blade servers.
Tower server
Tower servers are similar to desktop PCs, but because servers have more internal components and more slots, they are generally larger than PCs.

rack server
Rack servers don't look like computers; they resemble computer switches. They come in 1U, 2U, and 4U sizes. Rack servers are installed in standard 19-inch server racks.
Rack-mounted servers
blade servers
Blade servers are server units that can accommodate multiple cards within a standard-height rack-mount chassis. They are low-cost server platforms that achieve HAHD (High Availability, High Density) and are specifically designed for specialized applications and high-density computing environments. Like blades, each blade is essentially a system motherboard.

II. Workstation Concept
A workstation is a high-end general-purpose microcomputer. It is designed for single-user use and offers significantly more performance than a personal computer, particularly in graphics processing and parallel task handling. It typically features a large, high-resolution, multi-screen display, ample internal and external memory, and powerful information processing and high-performance graphics and image processing capabilities.

Workstations are mainly used in the following fields:
Computer-aided design and manufacturing (CAD/CAM)
This field is considered a traditional domain for workstations. The adoption of CAD/CAM technology can significantly shorten product development cycles while reducing the development difficulty of high-tech products and improving product design quality. In the CAD field, from large buildings to small components, graphics workstations demonstrate a strong competitive advantage due to their intuitiveness, high precision, and high efficiency.
Animation Design
The user base primarily consists of television stations, advertising agencies, film and television production companies, game software development companies, and interior design companies. Television stations use graphics workstations to create opening animations for various television programs; advertising agencies use them to create animated scenes for commercials; film and television production companies use them for computer special effects; game software companies use them as a development platform; and interior design companies not only use graphics workstations for design but also allow users to see 3D simulation renderings of the finished product before renovations even begin.
GIS Geographic Information System
Its target customer base primarily consists of urban planning units, environmental protection departments, geological survey institutes, and research institutes. They typically use graphics workstations to run GIS software. This allows users to gain real-time, intuitive understanding of project locations and surrounding facilities, such as streetlights and underground drainage pipelines. These large-scale data operations can only be efficiently performed on workstations with specialized graphics processing capabilities.
Planar Image Processing
It is an industry with a high degree of application penetration. Users typically use graphics workstations as the hardware platform and software such as Photoshop and CorelDraw as operating tools, focusing on image processing, advertising and brochure design, packaging design, textile pattern design, etc.
Simulation
In the military field, simulation technology is an effective means of training fighter pilots, tank drivers, and simulating maritime navigation; in the field of scientific research and development, it enables designers to conduct simulations on graphics workstations before building prototypes, allowing them to identify problems in a timely manner and modify the design.
III. Industrial Control Computer Concept
An industrial control computer, also known as an industrial control computer, is a general term for tools that use a bus architecture to monitor and control production processes, electromechanical equipment, and process equipment. An industrial control computer includes both hardware and software. The former shares the same attributes and characteristics as a traditional computer, integrating a monitor, touchscreen, host, CPU, graphics card, memory, hard drive, and peripheral interfaces. The latter includes an operating system, control network, computing power, and a human-machine interface.
Industrial PC
Currently, there are five main types of industrial control computers: IPC (Industrial PC via PC bus), PLC (Programmable Logic Controller), DCS (Distributed Control System), FCS (Fieldbus System), and CNC (Civil Numerical Control System). In the intelligent era spurred by Industry 4.0, industrial control computers, as an important component of traditional industrial fields, have long surpassed their original purpose of simple industrial control.
Features of industrial control computers:
High reliability: Industrial control computers typically use high-quality electronic components and materials, and undergo rigorous testing and certification, enabling them to operate stably for extended periods under harsh environments such as high load, high temperature, and high humidity.
Strong anti-interference capability: The circuit and interface design of the industrial control computer have high anti-interference capability, which can effectively avoid misoperation and failure caused by external signal interference.
High security: The industrial control computer's system and applications have high security, which can protect the confidentiality, integrity and availability of the system and data, and prevent malicious attacks and damage.
High scalability: Industrial PCs typically have a variety of expansion interfaces and card slots, which can easily expand various input/output devices, communication devices and control devices to meet the needs of different application scenarios.
Good real-time performance: Industrial control computers typically use real-time operating systems, which can meet the requirements of industrial control and automation tasks with high real-time performance, ensuring the accuracy and stability of control.
