1.	When two or more devices try to write data in a bus simultaneously, is known as ______________(a) Bus collisions(b) Address multiplexing(c) Address decoding(d) Bus contentionThis question was addressed to me in a job interview.My doubt is from Introduction of Memory Devices topic in section Memory Devices of Digital Circuits
Answer» Correct CHOICE is (d) Bus contention For explanation: Bus contention is an UNDESIRABLE state of the bus of a COMPUTER, in which more than one memory mapped device or the CPU is attempting to PLACE OUTPUT values onto the bus at once.
