Apr 23, 2025 · Socket programming is a way of connecting two nodes on a network to communicate with each other. One socket(node) listens on a particular port at an IP, while the other socket reaches out to the other to form a connection.

socket is what allows a process to communicate with other processes. This means that your applications will need a socket to communicate with TCP. From the perspective of your program, a socket is a lot like a Unix file handle, but it requests network services from the operating system.

socket() • int socket(int domain, int type, int protocol); • The domain specifies what type of socket we want—for this lecture, it will be one of PF_INET or PF_INET6 • The type for this lecture will always be SOCK_STREAM (meaning TCP, it could also be SOCK_DGRAM for UDP) • The protocol is the protocol number (e.g., one of IPPROTO_TCP or

Network sockets are application-level software implementation that enable communication between two processes over a network (which can be Internet or any other network type). It acts as a bridge between applications and the network stack, allowing processes to …

When dealing with stream sockets (TCP) Sockets, the TCP part is done for us. We can deal with the stream ABSTRACTION. How do you think a network connection may behave differently from a file? If it helps you can compare a file to reading/writing into a book and reading/writing a socket to texting/messaging a friend. How might this cause deadlock?

What is a Socket? Where does Socket fit in the Network Stack? When does write() block? Questions? Thank you!

WHAT IS A SOCKET? A socket is an endpoint for communication between two machines. It is a key concept in network programming, allowing processes to send and receive data over a network. Introduced in Berkeley UNIX in the 1980s, later adopted widely. Used for communication in client-server models.

As we’ve seen with sockets programs, sockets are a popular implementation for achieving network communication. After creating a socket, we use the bind system call to assign it to an address and port number.

Our goal: learn how to build network applications that communicate using sockets. Multiple sockets might exist in each host. A port number identifies each such socket in each host. 0 to 65535. Port numbers ranging from 0 to 1023 are called well …

A socket is the local abstraction that’s used to interact with that connection. So imagine a communication channel with a host/process on each end. Each
