Exam 3: Hardware: Input, Processing, and Output Devices

Key to the success of grid computing is a(n) _____ that acts as a grid leader and traffic monitor.

Sequential access storage devices allow data to be accessed more quickly than direct access storage devices.

Speech recognition technology _____.

_____ printers are generally faster than inkjet printers and can handle more volume than inkjet printers.

Chip-and-PIN cards employ a computer chip that communicates with a card reader using infrared frequencies so that the cards do not need to be swiped at a terminal.

The faster the clock speed of the CPU, ________.

With _____ access, it is possible to go directly to and access the needed data.

Explain the primary difference between RAM and ROM memory chips.

Large, bulky tape drives have been replaced with much smaller tape cartridge devices measuring a few millimeters in diameter that take up much less floor space and allow hundreds of tape cartridges to be stored in a small area.

The chip-and-PIN card technology ________.

Briefly discuss how the processing of data in a computer involves the interplay between its various hardware components.

The _____ is a special-purpose, high-speed network that provides high-speed connectivity among data storage devices and computers over a network.

Netbook computers are ideal for users who need to run demanding applications, have many applications open at once, or need lots of data storage capacity.

Green computing is focused at the efficient and environmentally responsible _____ of IS related products.

________ is a form of processing that speeds processing by linking hundreds or thousands of processors to operate at the same time, or in parallel, with each processor having its own bus, memory, disks, copy of the operating system, and applications.

Each CPU produces a series of electronic pulses at a predetermined rate, called the clock speed, which affects machine cycle time.

A(n) ________ is a special-purpose, high speed network that provides direct connections among data storage devices and computers across the enterprise. It also integrates different types of storage subsystems.

Dual core and quad core processors are now common and help boost the computer's processing power.

_____ is a storage method for less frequently needed data that makes it appear to be stored entirely on tape cartridges, although some parts may be stored on faster hard disks.

_____ are frequently used to capture input in standardized tests such as the SAT and GMAT.
