- What is the difference between a port and a socket?
Sockets are bi-directional, meaning that either side of the connection is capable of both sending and receiving data Therefore a socket can be created theoretically at any level of the OSI model from 2 upwards Programmers often use sockets in network programming, albeit indirectly
- What exactly is Socket - Stack Overflow
According to "TCP IP Sockets in C-Practical Guide for Programmers" by Michael J Doonahoo Kenneth L Calvert (Chptr 1, Section 1 4, Pg 7): A socket is an abstraction through which an application may send and receive data,in much the same way as an open file allows an application to read and write data to stable storage
- Differences between TCP sockets and web sockets, one more time
In fact, WebSockets is built on normal TCP sockets and uses frame headers that contains the size of each frame and indicate which frames are part of a message The WebSocket API re-assembles the TCP chunks of data into frames which are assembled into messages before invoking the message event handler once per message
- Difference between socket and websocket? - Stack Overflow
Websockets use sockets in their implementation Websockets are based on a standard protocol (now in final call, but not yet final) that defines a connection "handshake" and message "frame " The two sides go through the handshake procedure to mutually accept a connection and then use the standard message format ("frame") to pass messages back
- sockets - Whats the difference between streams and datagrams in . . .
there are three types of sockets stream (TCP, order and delivery guaranteed,no duplication,no length or char boundaries for data,connection-oriented,reliable, concurrency) datagram(UDP,packet-based, connectionless, datagram size limit, data can be lost or duplicated, order not guaranteed,not reliable)
- sockets - Why is bind () used in TCP? Why is it used only on server . . .
It assigns the "local" end's port number For a server socket, this is the ultimate way to go - it is exactly what is needed: have your socket be bound to port 80 for a web server, for example
- sockets - What does connection reset by peer mean? - Stack Overflow
It's fatal The remote server has sent you a RST packet, which indicates an immediate dropping of the connection, rather than the usual handshake
- sockets - Connectionless, unconnected connections - Stack Overflow
I just started learning about sockets programming, and I've run into a concept I've seen before but was quite confusing to me It seems that UDP connections are "connectionless, unconnected" connections Isn't "connectionless" and "unconnected" redundant? Are there then 4 types of connections? i e connectionless, unconnected ; connectionless
