Exam 3: Data Representation

Compilers and interpreters for high-level programming languages, such as C and Java, convert decimal numbers into ____________________ numbers automatically when generating CPU instructions and data values.

The representation format for each data type balances compactness, range, accuracy, ease of manipulation, and standardization.

​The advantage of using an index lies in the efficiency of record insertion, deletion, and retrieval.

A(n) ____________________ is an array of pointers to records.

Real numbers are represented in computers by using ____.

Generally, a byte is the largest unit of data that can be read from or written to a storage device.

When discussing computer processing, ____ refers to executing processor instructions, such as addition, subtraction, and equality comparisons, and "ease" refers to machine efficiency.

Twos complement notation is simple to understand for most people.

Decimal and binary notations are alternative forms of Boolean logic.

Intel microprocessors have been used in PCs since 1961.

____ occurs when the absolute value of a negative exponent is too large to fit in the bits allocated to store it.

A(n) ____ is an ordered list in which each element can be referenced by an index to its position.
