1. What input bit patterns will cause the following circuit to produce an output of 1? Inputs SIO Output If the output of an AND gate is passed through a NOT gate, the combination computes the Boolean operation called NAND, which has an output of 0 only when both its inputs are 1. The symbol for a NAND gate is the same as an AND gate except that it has a circle at its output. The following is a circuit containing a NAND gate. What Boolean operation does the circuit compute? Lg | Inputs — }>——> Output [ | | — fee — __ If the output of an OR gate is passed through a NOT gate, the combination computes the Boolean operation called NOR that has an output of 1 only when both its inputs are 0. The symbol for a NOR gate is the same as an OR gate except that it has a circle at its output. The following is a circuit containing an AND gate and two NOR gates. What Boolean operation does the circuit compute? Inputs [ io Output | i Use hexadecimal notation to represent the following bit patterns: a. 0110401011110 010 b. 111010000101010100010111 gronoiii4 npooran pac s009 c. 01004000 What bit patterns are represented by the following hexadecimal patterns? a. 5FD97 b. 610A c. ABCD d.010 If the memory cell whose address is 5 contains the value 8, what is the difference between wri value 5 into cell number 6 and moving the contents of cell number 5 into cell number 6? Suppose you want to interchange the values stored in memory cells 2 and 3. What is wrong with the following sequence of steps: Step 1. Move the contents of cell number 2 to cell number.3- Step 2. Move the contents of cell number 3 to cell number.2) ~ ve How many bits would be in the memory of a computer with 4KB memory? a Here is a message encoded in ASCII using 8 bits per symbol. What does it say? (See Appendix A) iting the
