What "FF" Means in Industrial Computing
In hardware specifications, FF is shorthand for form factor — the physical size, shape, mounting method and connector layout of a computer. Form factor is often the first decision in any deployment, because it determines where a system can be installed, how it is cooled, how it is serviced, and how many expansion ports it can carry. Two machines with identical processors and memory can behave very differently on a factory floor or in a branch office purely because of their form factor.
Industrial computing generally divides into four practical form factors: the mini PC, the thin client, the all-in-one (AIO), and the industrial PC (IPC). Each is optimised for a
