What is TCP socket used for?

A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. An endpoint is a combination of an IP address and a port number.

What is TCP listen port?

The Listening Ports section of the Network tab gives you information about the services and processes on your system that are waiting to service network requests. These services are listening on either a TCP or a User Datagram Protocol (udp) port.

Is HTTPs TCP or UDP?

TCP is used by HTTP, HTTPs, FTP, SMTP and Telnet. UDP is used by DNS, DHCP, TFTP, SNMP, RIP, and VoIP.

What is a socket vs port?

A port is a logical construct assigned to network processes so that they can be identified within the system. A socket is a combination of port and IP address. An incoming packet has a port number which is used to identify the process that needs to consume the packet.

How do sockets work?

Sockets are commonly used for client and server interaction. In a connection-oriented client-to-server model, the socket on the server process waits for requests from a client. To do this, the server first establishes (binds) an address that clients can use to find the server.

How do listening ports work?

Listen 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. When a process makes a connection to another process on its listen port, the originating process is assigned a temporary port.

What is listen IP?

An HTTP listener, also known as a network listener, is a listen socket that has an Internet Protocol (IP) address, a port number, a server name, and a default virtual server. Each virtual server provides connections between the server and clients through one or more listeners.

What is TCP and UDP with example?

TCP – used for traffic that you need all the data for. i.e HTML, pictures, etc. UDP – used for traffic that doesn’t suffer much if a packet is dropped, i.e. video & voice streaming, some data channels of online games, etc.

Where is UDP used?

UDP is commonly used for applications that are “lossy” (can handle some packet loss), such as streaming audio and video. It is also used for query-response applications, such as DNS queries.
