Computer Addressing modes online test May 15, 2018May 15, 2018 papertest 0 Comments addressing modes, addressing modes assembly, addressing modes in assembly language, addressing modes in computer architecture, addressing modes in microprocessor, addressing modes of 8086 Question #1: A modulus-12 ring counter requires a minimum of 10 flip-flops None of these 12 flip-flops 8 flip-flops Question #2: The NAND or NOR gates are referred to as “universal” gates because: they are available everywhere in the world. they can be used to build all the other types of gates. they are easier to implement. they are available in different IC families. Question #3: An active-HIGH SR latch has a 0 on the S input and a 1 on the R input. Now when the R input goes to 0, the latch will be ________. RESET STROBE SET CLR Question #4: How is a strobe signal used when serially loading a shift register? To determine which output has a HIGH value To cascade it with other shift register To turn the register set and reset To control the number of clocks Question #5: The NAND or NOR gates are referred to as “universal” gates because: they can be used to build all the other types of gates. they are easier to implement. hey are available in different IC families. none of these Question #6: A correct output is achieved from a master-slave JK flip-flop only if its inputs are stable while the Clock is LOW Clock is HIGH Master gives a reset signal to slave lave is ready to receive the input from master Question #7: Synchronization is achieved by a timing device called a ________. Strobe CLK Master clock generator Reset Question #8: An inverter circuit can be realized with how many NAND gates: None of these 3 2 1 Question #9: A sequential circuit gives an output depending upon: None of these both present- and past-state input. its present state inputs only. its present-1 state input only. Question #10: Which of the following statements is false? In 2’s complement, the leftmost bit cannot be used to express a quantity. The 2’s complement of 0 is 0. In 2’s complement, the significant information is contained in the 1’s of positive numbers and 0’s of the negative numbers. For an n-bit word (2’s complement) which includes the sign bit, there are 2n - 1 positive integers, 2n + 1 negative integers and one 0 for a total of 2n unique states. Congratulations, you passed! I'm sorry but you did not achieve the required score.
