flatbed

Flatbed scanners use a __ to illuminate the object being scanned.

Cold Cathode Fluorescent Lamp (CCFL)

The image in a scanner is recorded using a __ array, which generates an electrical charge in proportion to light intensity.

Charge Coupled Device (CCD)

The quality of a scanner depends on its __ , measured in pixels per inch (ppi).

resolution

Multi-function Devices (MFD) may use a __ scanner rather than a flatbed one.

sheet-fed

Older scanners use __-based software, while modern scanners are more likely to use WIA.

TWAIN

__ software can convert a text image into a computer-editable text document.

Optical Character Recognition (OCR)

__ is an interface name and while it is always capitalized it is not an acronym

TWAIN

Digital cameras store images on a flash memory-based card, such as __ or Secure Digital.

CompactFlash

Connecting a digital camera to a __ port will mount the camera storage as a Windows drive.

USB

If a PC does not have a flash memory card reader, you can connect the __ to the PC over USB to copy images.

camera

__ memory is main storage area for programs and data when the computer is running.

System

System memory is a type of __ memory called Random Access Memory (RAM).

volatile

__ means that data is only retained in the memory chips while there is a power source.

Volatile

If there is not enough system RAM, memory space can be extended by using disk space, called __.

virtual memory

System RAM is a type of RAM called __.

Dynamic RAM (DRAM)

__ stores each data bit as an electrical charge within a single bit cell.

DRAM

Variants of __ , or SDRAM, have been used for system memory since the mid-1990s.

Synchronous DRAM

SDRAM is synchronized to the __.

system bus

SDRAM for desktop PCs is packaged in __.

DIMMs (Dual Inline Memory Module)

Laptops use a smaller form factor for SDRAM called __.

Small Outline DIMM (SO-DIMM)

Double Data Rate SDRAM (DDR SDRAM) features __ data transfers.

"double pumped"

DDR has moved through __ technology updates to increase bandwidth.

DDR2, DDR3, and DDR4

Mass storage devices provide __ storage, where data is preserved when the power is turned off.

non-volatile

__ are one of the most widely used types of mass storage devices; they encode data magnetically on platters.

Hard Disk Drives (HDD)

The speed at which HDD disks spin is measured in __.

revolutions per minute (RPM)

__ is the delay that occurs as the read/write head locates a particular position on the drive.

Access time

Modern PCs and laptops use the __ interface for internal hard disks.

SATA (Serial ATA)

External HDDs are shipped in a special enclosure, which provides some combination of __ ports.

USB, Firewire, eSATA, and/or Thunderbolt

An external drive can also be connected via a network, referred to as __.

Network Attached Storage (NAS)

__ are designed to replicate or supplement the function of a hard drive, using flash memory.

Solid State Drives (SSD)

Solid state storage uses a type of non-volatile memory technology called __.

flash memory

Compared to spinning disk storage, ___ memory is very small, light, and much faster.

flash

In a __ drive, the SSD portion functions as a large cache, and the magnetic disc spins up only when non-cached data is accessed.

hybrid

Better performance is obtained from SSDs installed as __ adapter cards.

PCIe

__ , Digital Video Discs (DVDs), and Blu-ray Discs (BDs) are storage formats for consumer multimedia.

Compact Discs (CDs)

The data version of the CD (CD-ROM) has a capacity of __ MB.

700

DVDs deliver substantially more capacity (up to about __ GB) compared to CDs.

17

A recordable version of the CD is called __.

CD-R

CD-R is a type of __ media, meaning data areas once written cannot be overwritten.

Write Once Read Many (WORM)

Blu-ray Discs (BD) are replacing DVD as the media for distributing consumer multimedia.

The standard Blu-ray Disc has a capacity of __ GB per layer.

25

Optical drives are rated according to their __.

data transfer speed

A __ drive plugs into any spare USB port and is a popular way of packaging flash memory.

USB thumb

__ cards are used extensively in consumer digital imaging products.
