____ 21. Solid state storage devices store data in memory chips rather than magnetic or optical media and require less
power to operate while providing slower data access than magnetic data storage devices.
____ 22. The overall trend in secondary storage devices is toward use of direct access methods, higher capacity, and
increased volatility.
____ 23. MICR is a technology from the 1950s still used to speed the processing of checks.
____ 24. LCD monitors generally use between 35 and 50 percent less power than plasma screens and OLED monitors
use even less power than LCD monitors.
____ 25. Like a display screen, the quality or resolution of a printer’s output depends on the number of dots printed per
inch.
____ 26. One of the advantages of handheld computers is that they require little power relative to their size.
____ 27. 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.
____ 28. A blade server houses many computer motherboards that include one or more processors, computer memory,
secondary storage, network connections, and a common power supply and air-cooling source within a single
chassis.
____ 29. The scope of green computing is limited to the efficient and environmentally responsible design and
manufacture of all types of computers.
____ 30. Support for green computing is emerging as a new business strategy for computer manufacturers to
distinguish themselves from the competition.
