RISC

Reduced Instruction Set Computing

local What is RISC?

Riser Card

A riser card is normally used in a low profile case. Instead of the cards being perpendicular to the board, a riser card is used to make them parallel to the board, saving on the height. The riser card (short) is inserted to the mainboard perpendicular and the the others are inserted into the riser parallel to the main board.

Robot

Autonomically moving mechanical device. See the FAQ for the Czech origin of the word.
