Describe the different types of computers
Computers can be divided into analog and digital computers.
The main features of the analog computer are: the values involved in the operation are represented by the uninterrupted continuous amount, and its operation process is continuous. The simulation computer is affected by the quality of the components, the calculation accuracy is low, and the application range is narrow. Currently, there are few produce.
The main features of the digital computer are: the values involved in the operation are represented by intermittent digital quantities, and the operation process is calculated by digital bits. Because the digital computer has logic judgment and other functions, the digital computer works in a "thinking" manner that approximates the human brain. So it is also called "computer."


What is the most common type?
Common types: PCs, also known as microcomputers


What are the types of microcomputers?
There are four types of microcomputers. They are Network Computers, Industrial Control Computing, Personal Computers and embedded Computers.
1. Network Computers
1.1 Server
Specifically refer to some high-performance computers that can provide services through the Internet.
1.2 Workstation
Workstations are based on personal computers and distributed network computing. They are mainly for professional applications. They have powerful data computing and graphics and image processing capabilities. They are designed to meet engineering design, animation production, scientific research, software development, and financial management. High-performance computers designed and developed in areas such as information services and analog simulation.
1.3 Hub
A hub is a network device that shares media. Its role is to connect some machines to form a LAN. The HUB itself cannot identify the destination address.
1.4 Switch
The switch is a technical term for sending information to be transmitted to the corresponding route that meets the requirements by a method that is manually or automatically performed by the two ends of the communication.
1.5 Router
A wireless router is a kind of network device responsible for routing. It searches for a network path from the multiple paths in the Internet to provide communication to the user.
2. Industrial Control Computing
Industrial control computer is a kind of computer system that uses bus structure to detect and control the production process and its electromechanical equipment and process equipment.
2.1 IPC
It is Industrial PC based on PC bus
2.2 Programmable Logic Controller
A digitally-operated electronic system designed for use in industrial environments
2.3 Decentralized Control System

The decentralized control system is a series of distributed control systems with high performance, high quality, low cost, and flexible configuration. It can constitute various independent control systems, distributed control systems DCS, monitoring and data acquisition systems (SCADA), and can meet The need for process control and information management in various industrial fields.

2.4 Fieldbus system
It is an all-digital serial and two-way communication system.
2.5 CNC system
The modern CNC system is a numerical control system using a microprocessor or a dedicated microcomputer. The control logic is implemented by pre-storing the system program (software) in the memory to realize some or all of the numerical control functions and connect with the peripheral devices through the interface. The computer is called a computer. CNC, referred to as CNC system.

3. Personal Computers
3.1 Desktop
Also called a desktop computer, it is an independent and separate computer. It is completely unrelated to other components. Compared to notebooks and netbooks, the size of the computer is relatively independent of the host and monitor. Generally, they need to be placed on a computer desk. Or on a dedicated work bench.
3.2 Computer integrated machine
Computer Integrated Computer A computer integrated computer consists of a monitor, a computer keyboard and a mouse.
3.3 Notebook or Laptop
It is a small, portable personal computer, usually weighing 1-3 kg
3.4 Pocket PC
Pocket PC is a small, lightweight, easy-to-use, practical and inexpensive hand-held computing device that runs on embedded operating systems and embedded application software.
3.5 Tablet
The Tablet PC is a fully functional computer with no need for flips, keyboards, sizes, and shapes.
4. embedded Computers
embedded computer is an embedded system, which is an application-centered, microprocessor-based, software and hardware can be tailored to adapt to the application system's strict requirements on functionality, reliability, cost, size, power consumption and other comprehensive Special computer system.
