X Terminal
An X terminal consists of a piece of dedicated hardware running an X server as a thin client. This architecture became popular for building inexpensive terminal parks for many users to simultaneously use the same large server. X terminals can explore the network (the local broadcast domain) using the X Display Manager Control Protocol to generate a list of available hosts that they can run clients from. The initial host needs to run an X display manager.

Xeon
The Xeon is Intel's server-class microprocessors for PCs intended for multiple-processor machines. The first Xeon processor was released in 1998 as the Pentium II Xeon as the replacement of the Pentium Pro. The Pentium II Xeon was based on the P6 microarchitecture and used either a 440GX (a dual-processor workstation chipset) or 450NX (quad-processor, or oct with additional logic) chipset, and differed from its forerunner in that it had a full-speed, off-die L2 cache. Cache sizes were 512 kB, 1 MB and 2 MB, and it used a 100 MHz bus.
