What does the term socket refer to?

Definition: 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 socket used for in programming?

Sockets allow you to exchange information between processes on the same machine or across a network, distribute work to the most efficient machine, and they easily allow access to centralized data. Socket application program interfaces (APIs) are the network standard for TCP/IP.

Are ports and sockets the same thing?

Both Socket and Port are the terms used in Transport Layer. 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. The same port number can be used in different computer running on same software.

What does socket mean in CPU?

central processing unit
In computer hardware, a CPU socket or CPU slot contains one or more mechanical components providing mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows for placing and replacing the central processing unit (CPU) without soldering.

What programming language is socket?

Java and C#/C++. cli/VB+ should support the creation of a socket server with relatively few lines of code, as (the same as python) they have already-made libraries supporting most of the functionality. They are more verbose than Python though so you’ll write much more code.

How do ports work in networking?

A port is a number used to uniquely identify a transaction over a network by specifying both the host, and the service. The port number serves to uniquely identify that service on a particular host. The default port number for SMTP is 25, so packets of information relating to email are directed here.

What is a socket pair in networking?

A socket pair consists of a pair of connected (but unnamed) sockets. It is very similar to a pipe and is used in much the same way. A socket pair is much like a pipe; the main difference is that the socket pair is bidirectional, whereas the pipe has one input-only end and one output-only end (see Pipes and FIFOs).

What type of socket is created?

A socket is created with no name. A remote process has no way to refer to a socket until an address is bound to the socket. Processes that communicate are connected through addresses. In the Internet family, a connection is composed of local and remote addresses and local and remote ports.
