How to check computer port
In today's digital age, computer ports are an important bridge between external devices and computers. Whether it is data transfer, external monitor or charging, the role of ports cannot be ignored. This article will introduce in detail how to check the computer port, and attach the hot topics and hot content on the Internet in the past 10 days to help readers better understand the importance of the port.
1. Types of computer ports
Computer ports are usually divided into physical ports and logical ports. Physical ports are actual interfaces, such as USB, HDMI, etc.; logical ports are virtual ports in network communication, such as TCP/IP ports. The following are common physical port types:
| port type | Purpose | Common equipment |
|---|---|---|
| USB | Data transmission, charging | Mouse, keyboard, USB flash drive |
| HDMI | video output | Monitors, TVs |
| Type-C | Multifunctional interface | Mobile phone, notebook |
| Thunderbolt interface | High speed data transfer | External graphics card, hard drive |
2. How to check the physical port of the computer
1.Observe the appearance of the computer: Most laptops have ports on both sides, while desktops have them concentrated on the back of the case. Common ports include USB, HDMI, audio interface, etc.
2.Read the instructions: The computer manual or official website will list the port types and locations in detail.
3.Use system tools: In Windows system, you can view the connected port device through "Device Manager"; in Mac system, you can view it through "System Information".
3. How to check the logical port of the computer
Logical ports are mainly used for network communication. Here is how to view them:
| operating system | View method | Commands/Tools |
|---|---|---|
| Windows | command prompt | netstat -ano |
| Mac/Linux | terminal | lsof -i |
4. Hot topics and content on the entire network in the past 10 days
The following are technology-related topics that have been hotly discussed across the Internet recently, which may be related to computer port technology:
| hot topics | heat index | Main content |
|---|---|---|
