6. The flip-flop is a cell that is capable of storing how many bits of information? (a) Four (b) Three (c) Two (d) One 7. The decoder is a combinational circuits that converts binary information from the n coded input to a maximum of unique outputs. (a) m outputs (b) 2" outputs outputs outputs (c) 2"+1 (d) n2" 8. A register is a: (a) Group of binary numbers (b) Group of logical variables (c) Group of flip-flops (d) Group of numerical variables 9. A digital system is an interconnection of: (a) Software modules (b) Hardware modules (c) Binary modules (d) Logical modules 10. Digital modules can best be defined as: (a) Logical variables (b) Arithmetic variables (c) Registers (d) Flip-flops 11. The statement P: R2 + R1 can be described as : (a) Transfer the contents of R2 to R1 when P=1 (b) Transfer the contents of R1 to R2 when P=0 (c) Transfer the contents of R1 to R2 when P=1 (d) Transfer the contents of R2 to R1 when P= 1
