Learning how to program one of these socket types will give you the ability to extrapolate the knowledge to others. This variety may seem complicated at first, but luckily there is a more or less generic approach on how to use sockets of any kind in code. But even these two kinds of sockets can be of different types: datagram (or UDP), stream (or TCP), raw sockets, etc. For local processes, Unix domain sockets may be a better choice. For instance, network sockets can be utilized when two processes reside on different machines. Sockets are pretty diverse, and there are many ways to use them for inter-process communication. And of course, when the socket is not needed anymore, it should be closed. A socket can be opened, data can be written to the socket or read from it. A pair of sockets allow two processes to talk to each other. As it often happens with computer abstractions, the concept borrowed from the real world - more specifically from the AC power sockets. And indeed, there is a special kind of file for that called sockets.Ī socket is yet another piece of abstraction provided by the operating system. Since network communication is also a form of I/O, it'd be reasonable to expect that it should boil down to working with files as well. Here is a canonical example with read() and write() operations: // C-ish pseudocode The operating system provides a set of functions system calls to manipulate files that accept a file descriptor as an argument. Simplifying a bit, a file descriptor is just a unique integer identifier of a file within a process. Much like regular files on disk, computer mice, printers, modems, etc can be opened, read/written, and then closed.įor every opened file, the operating system creates a so-called file descriptor. In Unix-like operating systems, it's pretty common to treat I/O devices as files. No worries, there is going to be an article covering the details of HTTP later, while the rest of this article will be focused on how computers send arbitrary data over the network. And the word protocol can be explained as a sort of convention between two or more parties on data transfer format and rules. What is this Hypertext Transfer Protocol? Well, at this point, it'd be sufficient to think of it as a text-based (i.e.
