Exam 3: Data Representation

Explain the procedure to convert a binary value to its decimal equivalent.

Why do computers represent data with binary numbers?

The primary advantage of hexadecimal notation, compared with binary notation, is its ____________________.

More storage locations are required for a linked list than for an array with equivalent content because both data and pointers must be stored.

In ____ notation, nonnegative integer values are represented as ordinary binary values.

A sequence of characters that forms a meaningful word, phrase, or other useful group is a(n) ____________________.

In CPUs using a(n) ____________________ memory model, using twos complement or unsigned binary as the coding format for memory addresses is logical and typical.

In ASCII, NAK is sent to acknowledge correct receipt of data, and ERR is sent to indicate that an error has been detected.

Whether implemented in system or application software, almost all data structures make extensive use of pointers and addresses.

Double-precision integers are sometimes called large integers.

A(n) ____ is a whole number-a value that doesn't have a fractional part.

​A(n) ____ is a data element containing the address of another data element.

In computer terminology, each digit of a binary number is called a(n) ____________________.

Scientific and floating-point notation is far more complex than integer data formats.

A processor's efficiency depends on its ____________________.

____ notation always uses a fixed number of bits, with the leftmost bit representing the sign.

The leftmost digit in a bit string is called the ____.

In numbering systems other than the decimal numbering system, the term radix point is used for the period or comma.

A ____ data format combines two adjacent fixed-length data items to hold a single value.

Like ASCII, ____________________ is a coding table that assigns nonnegative integers to represent printable characters.
