How's it "not knowing the difference" to explain that the usage of the terms client and server switched over time, in the sense of which is local and which is remote?

An xterm client running on a VAX mainframe connects to an X11 server running on a Sun workstation: the X11 client is remote, the X11 server is local.

A web browser client running on a phone connects to a web server running in the cloud: the web client is local, the web server is remote.

Right?

Exactly! I, too, used to live in an office next to a machine room full of "web clients"! :-D

(Actually, I'm one of those deluded fools who claim a "server" provides a "service" to one or more "clients", who make "requests". Yeah, I know, but I figure somebody has to keep the joke funny.)

Here's how Jim Fulton (who wrote the early graphics drivers for X6) explains it:

>Given it's roots, X naturally used the technically-correct terms to describe its major components: the portion that abstracted display and input hardware into a service that could be used by other programs was called the "display server"; the portion that made use of those services was called the "display client." This later caused endless confusion who thought that "server" was a synonym for "big computer" (file server, database server, etc.) and "client" meant "small computer" (diskless client, etc.). Who knows, maybe it would have been easier had they been called "application server" and "application client" but that revisionist history.

Also interesting:

>Ultimately, the pendulum swung back with the advent of Web 2.0 technology and mobile devices. Now, we take it for granted that applications can run anywhere in the network and be accessed by any type of device. While X is primitive compared to JavaScript and HTML5 (whose ability to push computational tasks over the network into the display device were inspired by Java and NeWS), X did lay the initial groundwork. It also proved that an open source model could work for in business environments. Not too shabby for a technology that will soon be hitting its 30th anniversary.

Loled. I used to do phone support for x11 servers for pcs. This terminology confused people to no end
