What is a port? The most complete and strongest port number in history, collection!

2022-06-24 02:04:00 【Network technology alliance station】

Port is a very basic concept in computer network technology , Whether it's network implementation 、 Operation and maintenance 、 Or software development , Ports can be said to be the stuff we often deal with , Often hear or experience “ The port is occupied , Kill the related process ” Equal word .

So what is a port ？ What are the port numbers ？ What does each port number mean ？ And let the circle walk slowly ！

What is a port ？

In network technology , port （Port） There are roughly two meanings ： One is Physical port , such as ,ADSL Modem、 A hub 、 Switch 、 The interface used by the router to connect other network devices , Such as RJ-45 port 、SC Ports, etc .

Two is Logical port , Generally speaking, it means TCP/IP Port in protocol , The range of port numbers is from 0 To 65535, For example, for browsing Web Services 80 port , be used for FTP Service 21 Ports, etc .

What we will introduce here is the port in the logical sense . The port we call here , Not computer hardware I/O port , It's a formal concept of software . Tools provide different types of services , There are two types of ports ,

One is TCP port ,
One is UDP port .

When computers communicate with each other , There are two ways ：

One is after sending the message , You can confirm whether the information arrives , That is, there is a way to respond , This method mostly adopts TCP agreement ;- One is to ignore it after sending , Do not confirm whether the information has arrived , This method mostly adopts UDP agreement .

The ports provided by the services corresponding to these two protocols , It can be divided into TCP port and UDP port .

Port classification

Recognized port （Well-KnownPorts）： Range from 0 To 1023
Dynamic port （Dynamic Ports）： Range from 1024 To 65535

Recognized port

They are tightly bound （binding） In some services . Usually the communication of these ports clearly indicates the protocol of a certain service . for example ：21 Port allocation FTP service ,25 Port allocation SMTP（ Simple mail transfer protocol ） service ,80 Port allocation HTTP service ,135 Port allocation RPC（ Remote procedure call ） Services, etc. .

Dynamic port

It's called dynamic ports , Because it A service is not always assigned , It's dynamic allocation . Dynamic allocation refers to when a system process or application When the program process needs network communication , It requests a port from the host , The host assigns... From the available port numbers One for it to use . When the process is shut down , At the same time, the occupied port number is released .
