A traditional desktop computer usually has a computer tower, monitor, mouse, and keyboard. An all-in-one desktop, however, tries to combine these. The actual computer will be inside of the (sometimes over-sided) monitor, and the monitor itself may include a touchscreen. You will still usually want a keyboard, rather that trying to use the on-screen one, and a mouse my be useful as well. You will at least be able to do away with the computer tower, however.

No you do not need a dell keyboard. Any keyboard, screen, or mouse will be compatible with your Dell PC with the exception of Apple products.
A tower is the part of the computer which all the main devices are located. The tower is where you first turn your computer on. A desktop is the same thing, a desktop consists of a Tower, Monitor, Keyboard, Speakers, and a Mouse.
One option would be to implement your applications in QNX, and use the incredibly powerful networking capability and their IPC capability.
