Exam 3: Computer Hardware

A _______________ drive is a new, innovative form of storage that uses semiconductor memory and transistors that can be programmed to store data for virtually unlimited periods without power.

The central processing unit (CPU) is the main processing component of a computer system.

_______________ bytes of storage are needed to represent the name "Sarah."

Active RFID chips are self-powered and must be close to the reader to transmit their signal.

Some microcomputers are powerful enough to support applications with heavy mathematical computing and graphics display demands, such as computer-aided design (CAD) or investment analysis.

High speed storage media cost less per byte and provide higher capacities than lower-speed storage media.

Floppy disks consists of a polyester film disk covered with an _______________ compound.

Computing technology that can be used to draw or write on a pressure-sensitive graphics table is called _______________-based technology.

OCR stands for ____________________.

According to the text, which of the following is considered by millions of computer users to be the primary function of the desktop PC?

Which of the following does not apply to a personal digital assistant (PDA)?

The computing power of microcomputers currently exceeds that of the mainframe computer of previous generations, at a fraction of the cost.

Web-enabled personal digital assistants use touch screens, pen-based handwriting recognition, or keyboards, so mobile workers can send and receive e-mail, access the Web, and exchange information with their desktop PCs or Web servers.

The clock speed of a microprocessor today is commonly expressed in teraflops; earlier microcomputer speeds were reported in gigahertz.

According to the text, using web-enabled PDAs allows workers to realize all the following benefits except:

_______________ technology is a form of input technology commonly used by banks on their ATM cards.

Printing information on paper is the most common form of information output.

_______________ cards are a form of input technology. These cards have an embedded microprocessor chip and several kilobytes of memory.

Video displays and printed documents have been, and still are, the most common forms of output from computer systems.

RFID stands for ____________________.
