Explain the process of inserting an element in a list stored in contiguous memory.

The ____ data type has only two data values-true and false.

A(n) ____________________ integer uses one bit to represent whether the value is positive or negative.

​List the capabilities that any data and information processor, whether organic, mechanical, electrical, or optical, must have.

Recall that scientific notation, including floating-point notation, trades numeric range for ____________________.

The fractional portion of a real number is represented by digits to the right of the ____.

With unsigned integers, the lowest value that can be represented is always ____________________.

A(n) ____________________ is a data structure composed of other data structures or primitive data elements.

____________________ notation uses the base-8 numbering system and has a range of digits from 0 to 7.

The assignment of numeric codes to characters follows a specific order called a(n) ____.

​Computer systems represent data electrically and process it with ____________________

A(n) ____________________ combines related data items in much the same way a record does, but it extends the record to include methods for manipulating data items.

ASCII is a 7-bit format because most computers and peripheral devices transmit data in bytes and because parity checking was used widely in the 1960s to 1980s for detecting transmission errors.

Unicode is widely supported in modern software, including most OSs and word-processing applications.

Computers are designed to process character data and can therefore represent characters directly.

In the decimal or binary notations, the symbol used to represent a digit and the digit's position in a string determines its ____.

A(n) ____________________ is the location of a data element in a storage device.

____________________ numbers often designate memory addresses.
