Network port From Wikipedia, the free encyclopedia. A network port is a number that identifies one side of a connection between two computers. Computers use port numbers to determine to which process or application a message should be delivered. As network addresses are like street address, port numbers are like suite or room numbers.

List of Well-Known TCP Port Numbers Well-known ports are specified in RFC 1700. In TCP/IP and UDP networks, a port is an endpoint to a logical connection and the way a client program specifies a specific server program on a computer in a network. The port number identifies what type of port it is. For example, port 80 is used for HTTP traffic. Some ports have numbers that are pre-assigned to them by the IANA, and these are called the well-known ports which are specified in RFC 1700.

What are FTP ports? Best Answer: File Transfer Protocol (FTP) (Port 21) is a network protocol used to transfer data from one computer to another through a network, such as over the Internet. FTP is a protocol for exchanging files over any TCP/IP based network to manipulate files on another computer on that network regardless of which operating systems are involved (if the computers permit FTP access).

- An endpoint (socket) is defined by the combination of a network address and a port identifier. Note that address/port does not completely identify a socket (more on this later). The purpose of ports is to differentiate multiple endpoints on a given network address. You could say that a port is a virtualised endpoint.

Port (computer networking) In computer networking, a port is an endpoint of communication in an operating system. While the term is also used for physical devices, in software it is a logical construct that identifies a specific process or a type of network service. A port is always associated with an IP address of a host and the protocol type of the communication. It completes the destination or origination network address of a message. Ports are identified for each protocol and address combination by 16-bit unsigned num

What is the difference between port and socket in Internet terminology? Port: In simple language, Port is a number used by a particular software to identify its data coming from internet. Each software like, skype, chrome, youtube has its own port number and thats how skype or youtube knows which internet data is for itself. Socket: IP address and Port  together is called Socket. It is used by another computer to send data to one particular computer's particular software. IP address is used to identify the computer and Port is to identify the software such as IE, Chrome, Skype etc.

Port Number Definition - A port number is the logical address of each application or process that uses a network or the Internet to communicate. A port number uniquely identifies a network-based application on a computer. Each application/program is allocated a 16-bit integer port number. This number is assigned automatically by the OS, manually by the user or is set as a default for some popular applications.

Port forwarding In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall.

tunneling or port forwarding Tunneling, also known as port forwarding, is the transmission of data intended for use only within a private, usually corporate network through a public network in such a way that the routing node s in the public network are unaware that the transmission is part of a private network.

Computer Ports and Their Role in Computer Networking In computer networking, the term port can refer to either physical or virtual connection points. Physical network ports allow connecting cables to computers, routers, modems and other peripheral devices. Several different types of physical ports available on computer network hardware include: Ethernet ports.

What is Port Forwarding? Port forwarding is an excellent way to preserve public IP addresses. It can protect servers and clients from unwanted access, hide the services and servers available on a network, and limit access to and from a network. Port forwarding is transparent to the end user and adds an extra layer of security to networks.

TCP/IP Ports Network Applications that use the TCP/IP suite utilize sockets to communicate with one another. A socket is the combination of an IP address and a port. You can envision a socket like the following illustration: So, on the one hand you have an IP address, say 10.1.1.1 and a service port like 25 for SMTP.

Port (computer networking) A port number is a 16-bit unsigned integer, thus ranging from 0 to 65535. For TCP, port number 0 is reserved and cannot be used, while for UDP, the source port is optional and a value of zero means no port. A process associates its input or output channels via an Internet socket, which is a type of file descriptor, with a transport protocol, an IP address, and a port number.

- Port forwarding configures a device (modem, router, or gateway) to allow a computer, application, or a service on the Internet to communicate with a specific computer on a private local area network (LAN). Port forwarding sorts the data from the Internet source to the correct port on your network. Port forwarding is most commonly used for applications such as online gaming, surveillance webcams, VPN setup, File Transfer Protocol, remote computer software, and Web server hosting.

Port (computer networking) A port is always associated with an IP address of a host and the protocol type of the communication, and thus completes the destination or origination network address of a communication session. A port is identified for each address and protocol by a 16-bit number, commonly known as the port number. For example, an address may be protocol: TCP, IP address: 1.2.3.4, port number: 80, which may be written 1.2.3.4:80 when the protocol is known from context. Specific port numbers are often used to identify specific services.

What is a Port? In computer terms, a computer or a program connects to somewhere or something else on the Internet via a port. Port numbers and the user's IP address combine into the who does what information kept by every Internet Service Provider. Ports are numbered for consistency and programming.
