B
Bandwidth
Bandwidth is the measurement of the speed and amount of data
that can be transferred via a connection – most commonly in
reference to the Internet and Broadband connections. Bandwidth
is measured in megabits per second (Mbps) and obviously the
greater the bandwidth the faster the connection.
BIOS

‘Bits per second’ or bps, expresses the rate at which data is
transmitted. Generally, the higher the bit rate, the better
the image and sound quality.
BlackBerry
‘Blackberry’ is a brand of hand held devices which allow
consumers to access their email e-mail and make phone calls
all from the one unit.
Bleeding
When printers “bleed” during print, it is a reference to the
spreading of ink onto the page. Too much bleeding will merge
and distort the image; not enough bleeding will leave too much
white space on the page which will also distort what is being
printed.
Bluetooth
The Bluetooth feature enables data to be passed between
compatible devices wirelessly within short distances using
radio frequency.
Borderless Printing
Borderless printing is quite simply printing without a border.
Borderless printing fills the page to the edges without
leaving a frame effect. Borderless printing can be an issue
when considering photo printing.
BPS/Mbps
A measure of speed - Bits Per Second - Bits per second /
Megabits per second are used to measure how quickly data can
be transferred. 1 Mbps is equal to 1 million bits per second.
Broadband
Broadband is a high speed, permanent, Internet connection. The
main advantages of Broadband over a dial-up connection is the
speed – anywhere from 10 to 100 times faster – and that it
operates parallel to the phone line so that you can access the
Internet without tying up the phone line. (When operated over
a phone line this is termed as ADSL & over a cable feed DSL)
Brightness
Monitor or Television brightness is measured in candles per
metre squared. Therefore the greater the number, the brighter
the picture will be.

cache rather than the original server, making the process
faster.
CardBUS/PCMCIA
CardBus/PCMCIA is a standardised form of card slot for
notebooks. The majority of storage and memory cards follow the
PCMCIA standards and therefore a CardBus/PCMCIA compatible
notebook can accept the majority of such external storage and
memory devices.
Car Dock
A car dock is a cradle and power charger for hand held PCs for
when the user is on the move.
Car Mount
Car mounts are designed to hold hand held equipment, such as
satellite navigation devices, in position whilst the car is on
the move
Card slot
Some photo printers feature a memory card slot which allows
you to print directly from your digital camera’s memory card.
CCD
A charge coupled device is an integrated, light sensitive,
circuit which stores and displays images and converts the
image pixels into electrical charges. The intensity of each
charge is representative of the colours position on the colour
spectrum.
CD & DVD Drives
PC users need at least a CD-ROM to install software but unless
you're buying a budget laptop, then look for a CD-RW drive so
you can burn your own CDs. For watching movies and playing
games consider a CD-RW drive that doubles as a DVD drive. Some
higher end laptops offer DVD-rewritable drives, which can
store up to 8.5GB on one DVD disk but unless you need to store
huge files, such as movies or realms of MP3s, you may not need
these more expensive DVD-RW drives.
CD/DVD Printing
Some printers have the ability to print onto CDs and/or DVDs.
Clipboard
A clipboard is a temporary storage area for holding cut or
copied text and images, when transferring the data to a
different sentence, document or even programme.

system is one of the most popular and is an acronym for the
colours it uses; Cyan, Magenta Yellow and Key (Black).
COM
COM Ports, such as COM1 and COM2 etc, are 'serial
communication ports'. These are now relatively old technology
(external dial-up modems plug into COM ports on the back of
the PC) - and most devices now use USB instead.
Compact Flash Cards
A compact flash card is a form of memory card which uses flash
memory to store data. Compact flash cards are relatively small
and as such are ideal for storing data for transfer between
devices. Compact flash cards are most commonly used for
storing images taken on digital cameras and can be used to
transfer such images to printers or computers.
Component Video
Three connectors (usually red, green and blue RCA jacks)
transmit and receive component video signals; the combination
of these signals conveys all the picture information.
Compression
The process of compression is the reduction or compression of
a file’s size – most commonly images - to ensure that a
greater number of files can be stored. However, the more a
file is compressed the more distorted it can become.
Computer Memory
Every computer comes equipped with a certain amount of
physical memory, usually referred to as
RAM (Random Access Memory). Computers store running
applications and data in the RAM. To find out how much memory
you'll need, take into account your Operating System and the
applications that you plan to use. You'll need at least 256MB
for Windows XP, 512 for Vista & 256 for Linux.
Connection Interface
Most printers connect via USB to your PC, though in some cases
it might be through a parallel
printer cable. Ethernet is also used in some printers as
this allows you to easily connect the printer to a network.
Console
Console is a generic term used to describe a computer system
which is specifically designed for the purpose of gaming.
Continuous Shooting Mode
The continuous shooting mode allows multiple pictures to be
taken in quick succession. When a picture has been taken it
needs to be stored onto some form of memory device. It can
take several second for the process to be completed and this
stops the next photograph being taken. However, with
continuous shooting mode the image is instantaneously stored
onto a temporary file before being transferred to the
permanent file later, allowing the photographer to continue
‘shooting’ without the need to wait between each image.
Continuous shooting mode is often used for action shots where
the subject is continuously moving and changing.
Contrast
The contrast of a television screen or PC monitor refers to
the colouring. Contrast is the ratio of dark colours to light
colours. The greater the contrast level is, the more defined
the picture will be.
Cookies
When navigating the Internet, user behaviour and details may
be stored on your computer when visiting some websites. The
files that are created are known as cookies. Cookies can be
used to speed up navigation as login details and other
preferences can be recalled quickly when returning to some
websites.
CPU

stationary e.g. within the office or home study rather than be
mobile and, as a result, are much larger machines which can be
difficult to manoeuvre.
Digital Camera
Card Readers
An alternative to plugging your digital camera into a
computer, or the digital camera card into some printers, is a
digital camera card reader which is plugged into the user’s
computer and can be left plugged in. All the user needs to do
is plug the camera card into the reader to access.
Digital Desktop PC

DPI
DPI – Dots per inch – specifies how many dots there are per
inch of image. When printing images, the printer creates the
image through a series of dots. A general rule of DPI is that
the greater the DPI is greater the definition of the image
will appear.
Drivers
Any peripheral that you attach to your PC or laptop, such as
printers, scanners and sound cards will require a driver. This
is a program (usually supplied on a CD or DVD when you
purchase the peripheral) that acts as the interface between
the PC Operating System and the peripheral. It is worth noting
that if you have a problem with any peripheral, you can cure
many issues by downloading the latest version of drivers for
that product on the Internet.
Dual Core
Dual-core computers combine two processor chips into one
allowing the computer to operate more quickly and run even
more applications simultaneously in comparison to a single
core processor.
Duplex
A duplex function on a printer allows automatic printing on
both sides of a single sheet of paper.
Duty Cycle
The duty cycle is the maximum usage level per month for a
printer. You should choose a printer with a duty cycle that
exceeds your current production needs to ensure a longer life
for your printer.
DVD
DVD - Digital Versatile Disc – is a large storage capacity
disc. Most computers today have the ability to read DVD’s and
many computers today also have the ability to write and
re-write (also known as ‘burn)’ DVD’s. This simply means that
computers can transfer data onto DVD’s for storage.
DVI
Digital Video Interface - DVI - is a type of cable connector
which provides a high-bandwidth, digital connection between a
video source and a display device.

with FireWire connections such as digital cameras and
camcorders. FireWire connections have an emphasis on plug and
play; they are simple and easy to use, as well as being very
quick.
Fixed Focal-Length Lens
If you just want to take pictures of groups of your mates then
a budget camera with a fixed-focal-length lens is perfect for
the snap shooter. As these are the lowest spec on the market,
there’s usually no optical zoom but if you look for a version
with macro and landscape modes then the lens will offer a
relatively wide angle of view.
Fixed Zoom lenses
As the name suggests fixed zoom lenses have a fixed lens
attached to the body, but they also allow the user to attach
extra lens converters for wide-angle and close-up shooting as
well as filters and flash ring units. These cameras can be a
little larger than the retractable zoom types and more
complicated to operate but they do offer higher resolution
images.
Flash
Flash is used on a camera to provide artificial light on a
subject where visibility is poor. This feature is fairly
standard on cameras today.

screen is made up of millions of tiny liquid crystal
molecules, called pixels. These function like a camera
shutter, allowing light to either pass through or be blocked
as voltage is individually applied so they change state to
create an 'image'. The colour is added to the LCD display
through three filters (red, green, and blue) that are applied
to each pixel. LCD TV screens always maintain sharp, clear
pictures without reflection from artificial lights or bright
sunlight through windows.
LCD technology is extremely lightweight therefore products are
both highly portable and versatile. With screen sizes ranging
from 13" (4:3) to 40"+ widescreen, this means you can watch
LCD TV wherever you want!
LCD TVs also produce flicker-free images for a more
comfortable viewing experience with less eyestrain, even when
viewing close-up. Also, since no static electricity is
generated on an LCD screen it remains virtually dust free and
clean for perfect viewing all the time.
Li-ion
Li-ion – Lithium ion batteries – are a lightweight,
rechargeable, high-power battery. It is these features which
lend to such batteries being widely used in the Digital camera
and camcorder markets.

M
Macro Mode
Macro mode allows a digital camera to take pictures extremely
close-up to the subject. On some cameras this function will
allow photos to be taken from less than 10cm to subject.
Manual Exposure
Manual exposure allows the exposure settings of a camera to be
manually adjusted by the user to suit the environmental
lighting conditions.
Manual Focus
As with manual-flash and manual exposure, manual focus is
where a camera can be manually focused in relation to the
picture subject and environment.
Manual ISO Overrides
Many cameras come with pre-determined ISO (International
standards organisation) settings. So, for example, in well lit
environments a cameras functions and settings will
automatically adjust to meet a particular ISO standard but in
poorly lit environments the settings will adjust to meet
another particular ISO standard. The user, however, may choose
to use a manual ISO override function so that they have
complete manual control over the camera’s settings.
MB (Megabyte)
A byte is a collection of eight bits and is a measurement of
computer storage space. One Megabyte is worth one million
bytes – the greater the number of bytes then the greater the
storage capacity will be
Mbps / BPS
Megabits per second / Bits per second are used to measure how
quickly data can be transferred. 1 Mbps is equal to 1 million
bits per second.
Media Card Reader
An alternative to plugging your digital camera into a computer
or the digital camera card into some printers is a media card
reader which allows the media card to be read on the computer
without any need for cables or external adapters.
Megapixel (MP)
Obviously, a digital camera doesn’t store images on film,
instead when you take a picture, light is captured by the
Charge Coupled Device (CCD) and stored as a matrix of red,
blue and green coloured squares. These squares are known as
pixels with one mega pixel referring to 1 million pixels.
Therefore the more pixels there are, the better the image.
Technology has evolved, mobile phones now include 1 or even 2
MP capabilities and so generally the 3 megapixel camera is the
lowest spec on the market today. If you plan to publish images
on the web or include them in an email either use a camera
under 3MP or compress larger images otherwise file sizes
become too large.
Memory Type
Digital cameras can use a variety of memory storage devices,
differing from each model, or manufacturer, to the next. The
most common types are compact flash memory cards and SD cards.
(View Compact Flash Cards and
SD cards for more information)
Memory Type DDR
DDR is an integrated memory storage space in computers which
transfers data on both the rising and falling edges of the
clock-cycle. The DDR speeds up the computer system allowing
quicker and easier loading, navigation and storage of data.
Memory - RAM
Every computer comes equipped with a certain amount of
physical memory, usually referred to as RAM (Random Access
Memory). Computers store running applications and data using
the RAM. To find out how much memory you'll need, take into
account your operating system and the applications that you
plan to use. You'll need at least 256MB for Windows XP.
MHz (Megahertz)
Hz (hertz) and Megahertz (MHz) are terms used for the
measurement of transmission speed – how quickly a computer can

hand-held device which could store hundreds of CDs onto one
pocket-sized device, once they were compressed into MP3 files.
MP4
MP4’s are the compressed format of not only audio files (like
MP3s) but all multimedia files – moving pictures included.
This compression of multimedia files allows improved transfer
and storage capacity.
MPEG4
MPEG4 is the compression format used to compress audio, video,
voice and related formats of data. This compression format
allows quick transfers of data and increased storage capacity.
Multifunction Printers (MFPs)
All-in-one, or multifunction printers combine a printer with a
scanner and/or fax. With an all-in-one printer you can scan
documents and either store them in your PC or print them out
immediately, so your machine works as a copier. You can also
scan documents, and either send them to your PC for faxing, or
fax them directly from the multifunction.
Multi Mode Flash
A multi mode flash function includes additional features to
the ‘flash,’ such as red-eye reduction.

organiser with slightly increased capability with feature
functionality such as Internet and e-mail access and some
gaming capabilities etc. A palmtop is small enough to fit into
a user’s hand, or palm even.
Paper Tray Capacity
The paper tray capacity is the maximum amount of sheets of
paper that the printer can store in it’s tray at any time.
Parental Lock
Parental lock features are often available on Internet
browsers and more recently digital television and
satellite/cable receivers. It’s a system feature which simply
allows parents to control and block their children from
viewing particular programmes or websites.
PC
PC is quite simply an acronym for Personal Computer.
PC Card
A PC Card is a credit card-shaped device that plugs into the
PCMCIA (Type II PC Card) slot on your laptop. Modems, USB
connections (e.g. for your digital camcorder) and wireless LAN
radios are all available in PC Card form. PC Cards are handy
because they're easy to upgrade and affordable. However, most
laptops come with only one or two Type II PC Card slots,
forcing you to limit the number of PC Cards you can add.
PCI
PCI – Peripheral Component Interconnect – is a slot on a
computer unit which allows additional functionality devices to
be added to the computer, such as sound and graphics cards.
PCI Card
There are a number of PCI sockets on the motherboard and these

increased capability and feature functionality such as
telephone, Internet and e-mail access and some gaming
capabilities etc. A PDA is small enough to fit into a user’s
hand.
PDF
PDF – Portable Document Format – is the capturing of a
document in an image format. By standardising the document in
a pdf it will appear as intended regardless of which computer
it is viewed on. PDF was created by Adobe.
Photo Printer
A photo printer is similar to a standard printer however is
specifically designed for the printing of photo’s and high
quality images onto photo paper.
Picolitre
Ink droplet size is measured in picolitres, so for printing
the smaller the picolitre volume, the more defined the image
will be.
Pictbridge
Pictbridge is an industry standard term for printing directly
from camera (with/without the use of USB) without the need for
connecting to a computer.
Pixel
A pixel is literally a single dot on the screen and the pixels
form the image on your display. Therefore the more pixels
there are, better the picture. With HDTV there are many more
pixels (typically 1920 x 1080 or 1280 x 720) than with
Standard Definition TV (720 x 576), giving a crisper, clearer
and sharper picture.
Pixel Resolution
The pixel resolution indicates the number of pixels displayed
on a monitor or screen. The greater the number of pixels the
sharper and the higher the resolution will appear.
Plasma Screen TV
The screens on Plasma TV’s are perfectly flat. They produce
natural, vibrant colours while also maintaining a high level
of detail. This is because the pixels on a Plasma screen are
‘lit’ at once, unlike normal TVs, where the image is scanned
across the screen. The image is therefore sharper and
brighter.
This is great for regular room lighting and can be watched
from most distances and angles without affecting your viewing
experience. Even as you get closer to the screen, you will not
be affected by changes in picture or colour quality. They are
only a few inches thin which provides a lot of options when it
comes to installation.
In addition to stand mounting, they can be hung on a wall or
from a ceiling. All plasma TVs are designed in widescreen.
Plasma displays do not use electron beams, as conventional TV
displays do. They are therefore immune to the effects of
magnetic fields. This allows for speakers to be placed quite
close and will not compromise your home cinema set up.
Plug and Play
Plug and Play is a term which refers to the capabilities of a
PC/Notebook’s Operating System and its ability to ‘read’
attachable device. Windows systems boast plug and play
capability which, in theory, means that devices simply have to
be plugged in to be functional, without a need for additional
software installation
Plug-in Removable Hard Drive
A plug-in removable hard drive is a detachable hard drive
which can be plugged in and removed from your PC as and when
additional memory space is required.
Port Replicator
A 'port replicator' is a smaller, stripped-down version of a
docking station that mainly features ports, such as USB or
parallel. A port replicator can range from the size of a tube
of toothpaste to that of a docking station. A port replicator
is a more convenient way to increase your connectivity whilst
on the go as it’s smaller and lighter.
PPI (Pixels per inch)
PPI – pixels per inch – is the measurement unit for digital
images. And as the name suggests is a simple gauge of how many
pixels there are per-inch of image. The greater the PPI then
the greater definition there should be to the image.
PPM
PPM – pages per minute – indicates the number of pages a
printer can print within a minute. The PPM capacity will often
alter from black and white printing to colour.
Processor/Processor Type
Processor, sometimes referred to as the CPU (Central
Processing Unit), is the brain of the PC/ laptop. It's the
most important chip in a PC/laptop with. There are a variety
of processor types available depending on their application.
Processor Speed
Processor speed indicates how quickly the CPU (central
processing unit) operates- the CPU is in effect the “engine.”
Similar to cars, the faster the engine can run usually
indicates the better machine. And like cars, the quicker the
processor speed the more the processor will cost. Processor
speed is measured in MHz.

appear on the page - usually represented as a horizontal and
vertical measurement (e.g.: 600 x 300 dpi). This is crucial to
determining the quality of image a printer can produce. 600
dpi is perfectly adequate for most home applications.
Retractable Zoom Lens
For those who want a stylish compact camera with the option to
zoom in on the action, go for a camera with a Retractable zoom
lens. This type of camera is easy to transport as the lens is
retracted into the camera body when the camera is in off mode.
Usually featuring 2 or 3x optical zoom and a limited variety
of focus controls, this camera is perfect for those who want
to take the next step from a fixed-focal-length lens.

without interrupting their functionality.
Shutter Priority
Shutter priority is a camera function by which the user
selects the shutter speed and the camera will automatically
adjust the aperture exposure to suit the light. This technique
is useful for preventing motion blur.
Single Lens Reflex (SLR’s)
Single Lens Reflex (or SLR's as they are more commonly known)
allow the user to completely detach the lens from the body of
the camera and exchange it using interchangeable lenses. These
cameras are the most expensive on the market and usually offer
users between 6 and 12 megapixels. They provide flexibility
and have the added bonus that you don’t have to buy a new
camera to upgrade the quality of the lens.

getting the user to part with their money. Anti-spam software
and devices are available which can greatly reduce the level
of spam a user is receiving.
Speakers
User requirements for speakers will differ depending on their
function needs. A basic computer user, who uses their computer
mainly for basic tasks such as word processing and spreadsheet
creation, will find the standard built-in speakers for their
PC more than adequate. However, surround sound speakers and
sub-woofers will appeal to a consumer looking to purchase a
new plasma TV, for example, or a computer user with a keen
interest in multimedia functions such as creating and editing
their own DVDs.

LCD (Liquid Crystal Display) monitors are space saving flat
panel displays. They are sometimes referred to as TFT's (Thin
Film Transistors). They use a similar display technology to
that in a digital watch but are much more sophisticated.
The major selling point of LCD monitors is their stylish
design and slim profile, which creates a smaller "footprint".
LCD's also weigh approximately half as much as CRTs and also
require half as much power and emit much less electromagnetic
radiation.
LCD monitors provide bright, sharp displays as each pixel is
produced by a tiny cell which contains a thin layer of liquid
crystals. They also have a higher resolution than an equally
sized CRT monitor and so the visible screen is larger.
TIFF file
TIFF – Tagged Image File Format – is a file format by which
images can be saved, and shared. The TIFF format is a widely
accessible format which allows the user great freedom in not
only distribution and displaying of the images but also the

unlock, the data.
Widescreen
Widescreen is a format of image presentation on monitors. The
aspect of the image ratio is wider than standard format. The
presentation of an image in widescreen format may be because
the monitor’s physically a widescreen format or through it’s
built-in aspect ratio settings.
Wi-Fi/Wireless Networking
Many laptops include a built-in antenna for wireless
networking (802.11 or Wi-Fi). If your laptop doesn’t have
wireless built-in then you can simply add a wireless PC Card
to enable Wi-Fi networking. This Wi-Fi ability allows the user
to connect to the Internet when in proximity to an access
point – commonly know as Wi-Fi hotspots. More and more public
spaces are gearing up to allow Wi-Fi access – ranging from
cafes, restaurants and hotels to larger areas such as Norwich
City Centre.
