of connecting several (usually up to seven) peripherals in a 'chain' (serially) to a computer
. The data
cable originating from the computer passes from device
1 to device 2 to device 3 ... and so on until the last
device. Each device has an 'address,' and responds only if the data is specifically addressed to it. Both SCSI and USB port
schemes allow devices to be daisy-chained so that all connected devices are available to the user
, but only one at a time and not simultaneously.
