Fill in the blank(s) with the appropriate word(s).

Answer the following statements true (T) or false (F)

1. The transfer process from an interface board to a bus is controlled by the processor. 2. On a single-bus architecture system, the number of available slots limits the number of peripheral devices that can be connected to the system. One solution is to use an external bus to connect several peripheral devices through a single port. 3. It is possible to plug a printer, a scanner, a mouse, a modem, and other serial devices into a USB (universal serial bus) hub and then plug the USB hub into a single USB port that connects all those devices to the system. 4. Printers, external disk drives, and similar parallel devices must be connected directly to an interface card. 5. Simultaneous access requires independent data paths, so most mainframes use multiple- bus architecture.
