- Server: Designed to concurrently provide (shared) services to many people.
- Desktop: Designed for use by one person on their desk.
- Workstation: Usually a more powerful desktop.
Server
Hardware
A server is a computer that is used to provide shared services to many people. In a business context, the server is usually kept in a room dedicated to this purpose (the server room). Servers are often dedicated to one purpose: a file-server provides shared file-storage services to a group of people. An email server provides email collection, transmission and storage services to a group of people. This does not mean that the information is shared (though it can be) but that the computer and the services it provides are concurrently used by tens, hundreds or thousands of people. Servers are typically housed in tower or rack-mount cases. Servers do not typically have a dedicated screen, keyboard or mouse attached - they are managed by other means or by using a KVM-switch to share one keyboard etc between large numbers of servers.
Apart from the above, computer hardware designed for server use in an enterprise is often distinguishable from desktop computers (including workstations) in some or all of the following ways:
- rack-mount case.
- designed for "lights-out" usage.
- out-of-band management.
- boot-up messages diverted to remote monitoring devices.
- hardware RAID controllers.
- SCSI variants more often than SATA.
- front-accessible hot-plug disks.
- greater backplane bandwidth.
- higher noise levels.
- redundant hot-swap power supplies.
- support for SAN hardware.
- basic or absent graphics capability.
- often sold without a bundled keyboard or mouse.
There are home and SME "server" hardware devices which follow an almost opposite trend. They are designed to be very small quiet and unobtrusive and to sit on a desk or shelf. An example is the Excito Bubba, the size of a paperback book, sold without keyboard or mouse (it doesn't need one). These are also hardware designed specifically for a "server" rôle. There can be some overlap in form-factor with the "net-top" category of personal desktop computers.
Other usage
Obviously, in general this term means "one who serves" and can be applied to waiters in restaurants for example. This term is also used for software, for example the Apache project's HTTPD software is invariably described as web-server software. Some people associate the term most strongly with software.
Dictionary
Oxford says "a computer or computer program which manages access to a centralized resource or service in a network."
Desktop
Hardware
A desktop computer sits on the desk of one person and is primarily dedicated to the use of a single person. Whilst it might be shared consecutively (e.g. in "hot desking"), usually only one person is using it at any given time. It doesn't matter if the main part of the computer is placed under the desk. Desktops are often in tower cases (sometimes horizontally under a monitor) or all-in-one cases combined with the display. A desktop computer usually has a dedicated display, keyboard, mouse and other peripherals directly attached to it.
Other usage
Other usage isn't especially relevant but the term can obviously mean the upper surface of a desk. It can therefore be applied as an adjective for objects designed to be placed on that surface.
Dictionary
Oxford says "the working surface of a desk.
(also desktop computer)a computer suitable for use at an ordinary desk.
the working area of a computer screen regarded as a representation of a notional desktop and containing icons representing items such as files."

Workstation
Hardware
A workstation is a name usually reserved for a very high-performance desktop computer of the sort that might be used by scientists, engineers or on the trading floors of banks.
Other usage
The word "workstation" has a more general use. In some cases it means a position equipped for a worker. Sometimes furniture makers describe use this word in the description of their products. Some people use the term workstation to mean any personal computer. Sometimes the word is used to define a computer used, by one person at a time, for a specialised task.
Dictionary
Oxford says "a desktop computer terminal, typically networked and more powerful than a personal computer."

All-in-One
Here are some examples of current all-in-one desktop PCs:
You defame by publishing information hurting good reputation - possibly embarrassing, claiming incompetence or negligence.
You vilify if you defame by presenting the person's actions to be evil. Posting photos of someone sleeping under a tree, drunk may be defaming. Photo of that person raising a hand on a child is vilifying. Also, presenting normally mostly benign actions, making them to appear as evil is called vilifying (e.g. claim a woman who wears a red dress is "dressing like a whore")
Slander is a defamation that is false. (note for a long time in England one could win a lawsuit for defamation even if the defaming claim was proven true. Slander is always a defamation which is a lie)
I'm sorry but I won't give you any details on calumniate, I can only guess that's not a very frequently used synonym for slander. I think it implies verbal (or textual) form of slander, which on itself may take other forms (performing, parodying) but don't quote me on that.
You should also note libel (per StoneyB's comment) which is the same a slander except committed in a fixed/permanent form - slander is always in a volatile form (speech, gestures), while libel is fixed - in writing, as a picture, video, voice recording etc.
Best Answer
In New York (where those who are not "politically correct" are social pariahs) most corporate-run eating establishments prefer their wait-staff are referred to as "servers". However, in a private restaurant, (formal or informal) unless someone introduces themselves as "your server", it is still proper to say "Waiter," "Waitress," or "Bus boy/girl". "Captain" and "Maitre d'" are unchanged for male and female.
