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

A type of memory whose contents are not lost if the power is turned off or interrupted is said to be _____.

A coprocessor speeds processing by executing specific types of instructions while the central processing unit (CPU) works on another processing activity.

A redundant array of independent/inexpensive disks (RAID) is a method of storing data so that data can be accessed more quickly.

Moore's Law is a rule of thumb that states that transistor densities on a single chip will reduce to half every two years.

Compared with main memory, secondary storage:

Which of the following is related to Moore's Law?

The need for additional data storage capacity is one of the factors driving the growth in data centers.

_____ is an advanced optical disc technology that can store up to 3.9 terabytes, roughly 75-150 times more data than the Blu-ray optical disc system although it is the same size and shape as a regular digital video disc (DVD).

_____ are used to support engineering and technical users who perform heavy mathematical computing, computer-assisted design (CAD), video editing, and other applications requiring a high-end processor.

​A(n) _____ is a direct access storage device used to store and retrieve data from rapidly rotating disks coated with magnetic material.

_____ is a hard disk drive storage device that is set up with its own network address and provides file-based storage services to other devices on the network.

The scope of green computing is limited to the efficient and environmentally responsible design and manufacture of all types of computers.

Devices used to sequentially access secondary storage data are called direct access storage devices (DASDs).

_____ means that data can be retrieved without the need to pass by other data in sequence.

A _____ is a computer employed by many users to perform a specific task, such as running network or Internet applications.

Magnetic ink character recognition technology codes data on the bottom of a check or other form using special magnetic ink, which is readable by people and computers.

_____ is a technology that employs a microchip with an antenna to broadcast its unique identifier and location to receivers.

_____ involves capturing and editing data where it is originally created and in a form that can be directly entered into a computer, thus ensuring accuracy and timeliness.

_____ are credit cards embedded with computer chips containing key consumer and account data.

_____ is the backbone of a computer, connecting all of its components including the central processing unit (CPU) and primary storage and providing connectors for peripheral devices such as printers, external hard drives, sound cards, and video cards.
