q1-  Public key algorithms are based on mathematical functions rather than on simple operations on bit patterns. Select one: True False

Calculate the total number of bits per character. Record your answers in the chart. Character Code Frequency Total Bits A 000 4 В 001 C 010 14 D 011 13 E 100 7 F 101 17 N 110 19 What are the total bits in the original code? Reduce the number of bits used without losing any information from the chart using the Huffman Coding algorithm. Draw the Huffman Coding tree in the space provided below. Hint: You can use the Shape tool to draw the graph, or you can draw the graph by hand, then photograph or scan your graph to submit it.

Find the decimal values of the following signed (negative) numbers. First find a signed-magnitude binaryrepresentation for them and then convert them to decimal numbers: a. (71)8= (111001)2 signed-magnitude =b. (80C)16 = (100000001100)2 signed-magnitude =c. (10100101)2 = (-0100101)2 signed-magnitude =
