Question 1

Which standard govern parallel communications?
A)RS232
B)RS-232a
C)CAT 5
D)IEEE 1284

Accepted Answer

IEEE 1284 is the standard that governs parallel communications, specifically for connecting computers and printers.

Question 2

Which common bus specification provides the fastest data transfer rate?
A)VL bus
B)ISA
C)PCI
D)All of the above

Accepted Answer

PCI (Peripheral Component Interconnect) provides a faster data transfer rate compared to VL (VESA Local) bus and ISA (Industry Standard Architecture), making it the correct choice for the fastest data transfer rate among the options given.

Question 3

Devices that use the ____ bus are self-configuring.
A)EISA
B)ISA
C)MCA
D)PCI

Accepted Answer

PCI (Peripheral Component Interconnect) devices are self-configuring, meaning they can automatically configure their IRQs, memory addresses, and other settings, a feature known as Plug and Play.

Question 4

Which of following is not a valid bus in computer system ?
A)Data Bus
B)Memory Bus
C)Address Bus
D)System Bus

Accepted Answer

Memory Bus is not a specific type of bus in computer systems; rather, it is a concept that can involve several types of buses (like the data bus, address bus, and control bus) for communication between the memory and other components. The System Bus, Data Bus, and Address Bus are all recognized types of buses in computer architecture.

Question 5

The AT bus is also known as the ____ bus.
A)286
B)8-bit ISA
C)16-bit ISA
D)ISA

Accepted Answer

The AT bus is also known as the 16-bit ISA bus, which was introduced with the IBM PC/AT.
