port 1 –Cisco Systems, Inc.  1) On computer and telecommunication devices, a port (noun) is generally a specific place for being physically connected to some other device, usually with a socket and plug of some kind. Typically, a personal computer is provided with one or more serial ports and usually one parallel port. The serial port supports sequential, one bit-at-a-time transmission to peripheral devices such as scanners and the parallel port supports multiple-bit-at-a-time transmission to devices such as printers.

Port (computer networking) 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.

parallel port Most personal computers have both a parallel port and at least one serial port. On PCs, the parallel port uses a 25-pin connector (type DB-25) and is used to connect printers, computers and other devices that need relatively high bandwidth. It is often called a Centronics interface after the company that designed the original standard for parallel communication between a computer and printer.

- TCP and UDP Ports. As you know every computer or device on the Internet must have a unique number assigned to it called the IP address. This IP address is used to recognize your particular computer out of the millions of other computers connected to the Internet.

Port (computer networking) A port is identified for each address and protocol by a 16-bit number, commonly known as the port number. Specific port numbers are often used to identify specific services. Of the thousands of enumerated ports, 1024 well-known port numbers are reserved by convention to identify specific service types on a host.

Port (medical) Port (medical) In medicine, a port is a small medical appliance that is installed beneath the skin. A catheter connects the port to a vein. Under the skin, the port has a septum through which drugs can be injected and blood samples can be drawn many times, usually with less discomfort for the patient than a more typical needle stick. Ports are used mostly to treat hematology and oncology patients. Ports were previously adapted for use in hemodialysis patients, but were found to be associated with increased r

Open Router Ports & Their Security Implications [Technology Explained] Open Router Ports & Their Security Implications [Technology Explained] An open router port is the term used to refer to a virtual door allowing specific data in or out of your router. One example of a port is the most popular port 80. Port 80 is used for HTTP or Web traffic. If port 80 is closed outbound for your computer, then you would not be able to get to the Internet.

Port (computer networking) In computer networking, a port serves as an endpoint in an operating system for many types of communication. It is not a hardware device, but a logical construct that identifies a service or process.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 address of a communications session.A port is identified for each address and protocol by a 16-bit number, commonly known as the port number.Specific port numbers are often used to identify specific services.t is not a hardware device, but a logical construct that identifies a service or process.

Serial port In computing, a serial port is a serial communication interface through which information transfers in or out one bit at a time (in contrast to a parallel port). Throughout most of the history of personal computers, data was transferred through serial ports to devices such as modems, terminals and various peripherals.

Port forwarding 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.

Difference Between Socket and Port Socket vs Port. In the context of computer networking, a socket is an end point of a bidirectional communication that occurs in a network that is based on the internet protocol. Sockets will distribute the data packets that are coming through the communication channel to the correct application.

What is a USB Port? A USB port is a standard cable connection interface for personal computers and consumer electronics devices. USB stands for Universal Serial Bus, an industry standard for short-distance digital data communications. USB ports allow USB devices to be connected to each other with and transfer digital data over USB cables.

Understanding Port Forwarding â Beginners Guide Port forwarding is a technique that is used to allow external devices access to computers services on private networks. Most online gaming Applications will require you to configure port forwarding on your home router. To understand port forwarding you need to understand what a TCP/IP port is and how ports and IP addresses are used together. You will also need to appreciate the difference between internal and eternal IP addresses and ports. A TCP/UDP port identifies an application or service on a machine in a TCP/IP network.

port 1) On computer and telecommunication devices, a port (noun) is generally a specific place for being physically connected to some other device, usually with a socket and plug of some kind. Typically, a personal computer is provided with one or more serial ports and usually one parallel port.ort numbers are from 0 to 65535. Ports 0 to 1024 are reserved for use by certain privileged services. For the HTTP service, port 80 is defined as a default and it does not have to be specified in the Uniform Resource Locator (URL).
