There are several meanings of parallel device. It can mean having two or more computers working on the same problem at the same time. This is called parallel computing.
Or it can mean any device hooked up to the parallel port on a computer. Parallel ports are fairly obsolete, so you are less likely to see this version of parallel device in the future.
Depends, is the device serial or parallel?
serial device
Serial
A capacitor
Serial ports only allow one device to send and one device to receive at a time, where a parallel port can send and receive data at the same time.
it is used to interface between controller and peripheral device.. peripheral device otherwise called external device such as LED,LCD...

A fuse will not work successfully if it is connected in parallel with the device it is supposed to protect.First, it will blow because it has no resistance in series with it. Second, once it blows, the device still has power applied to it. Fuses must be wired in series.
The data bus of 8085 is 8 bit and so it will read or write 8 bits simultaneously.So it is Parallel Devise
to higher or lower the electricity.
The most common of all circuits used in industry and around the home is the parallel circuit. In industry all MCC controls are in parallel with the supply distribution and around the home all lighting circuits are in parallel with the supply distribution panel.
