Socket Designing

 Architecture Of Socket:-

Sockets are a type of inter-process communication (IPC) technique used for exchanging data between two or more processes in a network. They are an essential part of network programming and enable applications to communicate with each other and exchange data over the network.

A socket is essentially a software abstraction of a physical network connection and provides an endpoint for communication. A socket is identified by an IP address and a port number. The IP address is a unique identifier assigned to the machine, while the port number is a unique identifier assigned to the socket.

When two processes want to communicate with each other, they create a socket. The sending process connects to the receiving process’s socket and sends data, which is then read by the receiving process. Similarly, the receiving process can send data to the sending process’s socket.

Socket programming is a type of network programming that allows two processes to communicate with each other. It involves creating sockets, binding them to a specific port, and then using them to exchange data with the server. Socket programming is used to create client-server applications, where the client requests data from the server and the server responds with the requested data.

Socket programming is based on the client-server model, where the client sends requests to the server, which then sends a response back to the client. The client and server exchange data using a protocol such as TCP or UDP.

The socket programming model is divided into four layers: the application layer, the transport layer, the network layer, and the link layer. The application layer is responsible for providing an interface to the user. The transport layer is responsible for end-to-end delivery of the data, while the network layer is responsible for routing the data to its destination. Finally, the link layer is responsible for providing access to the physical network.

Sockets are used in a wide variety of applications, from web browsers to email clients to streaming media players. They enable applications to communicate with each other, exchange data, and share resources. Socket programming is a powerful tool for creating distributed applications and for connecting different applications, networks, and computing devices.
