What is a port? And what are its types

In the world of computing and networking, the term "port" or "port" refers to a specific channel on a computer or networking device that it uses to exchange data with other devices. A port can be thought of as a specific connection point that is used to implement a specific service or application on the device.

There are many different types of ports, and each is known by a number called a "port number". This number is used to identify the service or application to be accessed on the host machine. Here are some common port types:

TCP/IP Ports: The popular TCP/IP protocol is used to transfer data across networks. There are a set of predefined ports for specific applications, such as:

Port 80: Used for web service (HTTP). Port 443: Used for secure web service (HTTPS). Port 25: Used for outgoing email service (SMTP). FTP Ports: FTP is used to transfer files between computers over a network. Some common ports for FTP include:

Port 20: It is used for data transfer. Port 21: Control Connection. Email Ports: Different email protocols use specific ports to route email messages. Some common outlets for email include:

Port 110: Used to receive email (POP3). Port 143: Used to receive email (IMAP). These are just examples of some common port types. There are other types of ports that are used in different applications and depending on the specific needs of each application. Developers or network administrators may use dedicated ports to run their own applications or services.

SFTP Ports: These are used to transfer files securely using SFTP. Some common SFTP ports include:

Port 22: Used for SSH connection and secure file transfer. Routing Protocol Ports: They are used to exchange routing information between routers in computing networks. Some common ports for routing protocols include:

Port 520: Used for Routing Interior Protocol (RIP). Port 179: Used for BGP. NNTP Ports: These are used to exchange articles and news in online discussion forums. Some common ports for NNTP include:

Port 119: Used to transfer news (NNTP). Chat Protocol Ports: These are used for communication and interaction in chat and instant messaging applications. Some common ports for chat protocols include:

Port 5222: Used for the XMPP (Jabber) protocol. Port 6667: Used for IRC (Internet Relay Chat) protocol. These are just additional samples of the types of ports used in communications and networks. There can be more predefined ports or dedicated ports for specific applications and services according to individual needs and requirements.



Here are some additional types of ports: FTP Ports: In addition to the ports I mentioned earlier, there are also other ports used in FTP:

Port 990: Used for Secure Transfer Mode FTP (FTPS). Email Ports: In addition to the ports I mentioned earlier, there are some other ports used in the Email Protocol:

Port 465: Used for the Secure Email Service (SMTPS). Archive Transfer Protocol (SSH File Transfer Protocol, SFTP) Ports: Used for secure file transfer over SSH protocol:

Port 115: Used to transfer files using SFTP. Remote Desktop Protocol (RDP) ports: used to connect to and control a computer remotely:

Port 3389: Used for RDP. Game Ports: Used to communicate in network and online games:

Port 27015: A common port for Steam games. Voice over IP (VoIP) ports: used for VoIP:

Port 5060: Used for SIP (Session Initiation Protocol) for voice communications over the network. These are just a few more examples of the types of ports used in communications and networking. Remember that there are many other ports available that can be used for different applications and services.

TFTP Ports: These are used in TFTP, which is primarily used for simple file transfers, operating systems, and software updates. Some common ports for TFTP are:

Port 69: It is used to transfer files by TFTP protocol. Virtualization Protocol Ports: These are used in virtual machine protocols to manage and operate virtual environments. Some common ports for virtual machines are:

Port 902: Used for the VMWare Server protocol. Network Time Protocol (NTP Ports): They are used in the Network Time Protocol to obtain and synchronize time across the network. Some common ports for NTP are:

Port 123: Used to transmit and synchronize time across the network. Service Location Protocol, SLP Ports: These are used in the Service Automatic Discovery Protocol to find available services in the network. Some of the popular ports of SLP are:

Port 427: Used to discover services across the network. Multicast Streaming Protocol Ports: These are used for multicast transmission in networks. Some common ports for multicasting are:

Port 1755: Used for RTSP (Real-Time Streaming Protocol). These are some additional examples of port types used in communications and networking. It should be noted that there are many other ports available that can be used for different applications and services.

Web Transfer Protocol (HTTP Ports): These are used to transfer web pages and content over the Internet. Some common ports of HTTP are: Port 80: Used for unencrypted HTTP connections. Port 443: Used for encrypted HTTPS connections. ZIP Ports: These are used to transfer compressed files over the network. Some popular ports for ZIP are:

Port 21: It is used for FTP service to transfer compressed files. Content Delivery Protocol Ports: These are used to efficiently deliver content and files over the network. Some of the common ports for CTP are:

Port 1935: Used for streaming media and video over the Internet (RTMP). Remote Procedure Call, RPC Ports: used to execute and call remote processes and programs over the network. Some common ports of RPC are:

Port 135: Used for RPC service. Data Transfer Protocol Ports: Used to transfer data between computers and servers. Some of the common ports for data transfer protocol are:

Port 20: It is used for FTP service to transfer data. Port 21: It is used for FTP service to transfer commands. These are just a few more examples of port types. Please note that there are many other ports available that can be used for different applications and services.



Instant Messaging Protocol Ports: used to communicate via instant chat protocols. Some popular outlets for instant chat are:

Port 5222: Used for XMPP (Extensible Messaging and Presence Protocol). Port 1863: Used for the MSN Messenger protocol. Secure Communication Protocol Ports: These are used for secure communications over the network. Some common ports for secure communication are:

Port 22: Used for SSH (Secure Shell). Port 443: Used for encrypted HTTPS connections. File Search Protocol Ports: These are used to search for files and resources over the network. Some common outlets for searching files are:

Port 137: Used for NetBIOS (Network Basic Input/Output System) protocol. Port 139: Used for the NetBIOS Session Service protocol. Real-Time Streaming Protocol Ports: These are used to stream media and data across a network in real time. Some common ports of a real-time streaming protocol are:

Port 554: Used for RTSP (Real-Time Streaming Protocol). Remote Access Protocol Ports: These are used to access and control computers remotely. Some common ports of remote access protocol are:

Port 3389: Used for RDP (Remote Desktop Protocol). These are some additional examples of port types used in communications and networking. Please note that there are more ports available that can be used for various purposes.
