Exam 1: Data Representation

Assuming that each of the following bit patterns originally had even parity,which one contains an error?

How many different bit patterns can be formed if each must consist of exactly 6 bits? ____________

Which of the following bit patterns represents the value -9 in two's complement notation?

Given that 1 foot = .3048 meters,write a Python script that will convert a height given meters to a height given in feet and inches.

To what does the term "normalized form" refer in the context of floating-point notation?

Which of the following representations in two's complement notation represents the largest value?

Which of the following systems is least efficient when encoding numeric values?

What is the smallest negative integer that can be represented in a two's complement system in which each value is represented by eight bits? ____________

Which of the following data storage systems provides the most efficient random access to individual data items?

Data compression techniques apply various principles to reduce the size of data.One,called _______________________,avoids repeating long strings of the same data item.Another,called _______________________,encodes the difference between consecutive blocks of data rather than encoding each block in its entirety.Still another,called _________________________,uses short bit patterns to encode frequently occurring items and longer patterns to encode less frequent items.

Using a two's complement notation system in which each value is represented by a pattern of six bits,represent the value -5. ____________

When using two's complement notation,what bit pattern represents the negation of 01001010? ____________

Which of the following storage systems is best suited for storing and retrieving long strings of data that are processed in their sequential order?

Which of the following mass storage system does not require physical motion?

What is the largest positive integer that can be represented in a two's complement system in which each value is represented by eight bits? ____________

In a two's complement system,what value can be added to any other value without causing an overflow? How many values in the system have this property? Explain your answer.

a.What is the output of the circuit below? b.In general,how does the three-bit input pattern across the top of the diagram relate to the circuit's output?

A computer's main memory consists of numerous memory cells,each of which contains ________ bits.Each memory cell is identified by a numeric value called the cell's _________.

In which of the following addition problems (using two's complement notation)does an overflow error occur?

Using an 8-bit floating-point format in which the most significant bit is the sign bit,the next three bits represent the exponent field in excess notation,and the last four bits represent the mantissa,write the bit pattern that represents the value 1 3/4.(Use normalized form.) ____________
