Multiple-choice questions.
Colour depth Would affect the quality of an image produced by a
scanner
A dedicated device Dedicated devices are computers such as ATMs, point-of-
sale devices (that is, tills and card machines) and even
fridges and air-conditioners.
GPS Technology that determines current position.
Lumen Unit for measuring light output – typically describes the
output of an LCS projector.
UPS Device that is used to protect computers against power
surges.
HDMI Type of port that sends high-definition video and sound to a
monitor.
Plug-and-play Series of technologies about how a peripheral
communicates with the computer when connected to it.
Driver Software used to control a specific hardware device.
The export option The export option on the File tab can be used to convert
Word documents to other formats

CSV files CSV files are also text files where data items are separated
with a comma.
Special paste option The special paste option can be used to paste links from
other documents.
A section A section is a part of a document where the page
formatting differs from the rest of the document.
An accelerometer in a Determines the way the device is held or moved.
smartphone (Determine how many steps you take)
Wireless output Wireless output devices use Wi-Fi, Bluetooth or near-field
devices communication (NFC) to communicate with the computer.
DEVICE DRIVERS Device drivers are software programs that are separate
from the device. Most operating systems also have a set of
standard device drivers installed for things such as computer
mice, keyboards and hard drives (internal and external).
These devices are often referred to as plug-and-play
devices.
OCR OCR stands for optical character recognition and it is a
software program designed to convert printed characters
(such as those on a hard copy document) into digital text.
OCR is most commonly found in specialised scanners used
for archiving or document management.
A client computer A server computer provides resources/services in a network
A server computer A client computer uses resources/services provided by
servers in a network
Thin clients A thin client is a computer that runs from resources stored on
a central server instead of a localized hard drive. Thin clients
work by connecting remotely to a server-based computing
environment where most applications, sensitive data, and
memory, are stored.

Defragmentation The defragmentation utility will rearrange and consolidate
the distributed parts of files on disk. So that it can be
obtained faster.
Memory • Retain data and instructions while working.• Electronic •
Fast • More expensive per GB
Storage • Permanently retains programs and data. • Magnetic,
optical or electronic. • Slower speed. • Cheaper per GB
Driver Software that controls the device. Where can a driver be
found? • Internet • Shop from a store. • May be included in
operating system
INFORMATION PROCESSING CYCLE
INPUT In the input stage, the data is entered into the computer.
PROCESSING The central processing unit (CPU) inside the computer then
takes that binary code and does the calculations needed
to get that data to display in a way that makes sense to the
user.
STORAGE Storage is where the computer takes the input and stores it
in its memory banks.
