Art in ICT
- Graphics software
- Brush setting (bigger/smaller)
- Distortion - add movement ot image
using 'ripple' 'wave' and 'twirl'
- Cloning - clonong background
to remove unwanted objects
- Layering - logos can be
made with layers with
different transparencies
- Colour effect,palettes,gradients
- Vector/bitmap graphics
- Vector is made with formulas
and can be resized wuthout
losing quality
- Bitmap uses pixels that have
different colours to make up an
image, takes up more momory
and zooming blurrs the image
- Webcam
- video camera in a fixed
position connected
directly to the computer
- can view real time images/live video
- Set up to monitor
weather,skiing conditions
on mountains and traffic
on congested roads
- Microphone
- input sound
into the device
- sound card puts
it into computer
which converts it
into a digital file
- used for voice
recognition in
computers
- Sound and music
- Musical Instrument Digital Interface
- as you play digital
signals are input and
stored as data files
- sound can be stored as
analogue (vinyl records)
or as digitised versions
in the form .wav/ ,mp3
- sound cards are needed for
computers to process sound
- heavy speakers = woofers
high frequency speakers
= twitters
- Synthesizers =
produce/sequence
many different
musical sounds
- Notator = can write musical scores
- internal memory/backing storage
- RAM/ROM
- Random Access
Memory data stored on
it can be changed 3GB
of RAM on computers
- small capacity + data is lost
when power is turned off
- Read-Only Memory data
can be read but nothing
can be saved or changed
- Disk Cache
- Recently read data from the
disk is put on the Disk cache
so if the data is required
again it makes the process of
getting the data X1000 faster
- Units used in ICT
- bit = 0 or 1
- Byte = 8 bits = the letter A
- Kilobyte = 1024 bytes = 1024 characters
- Megabyte = 1024 KB = single digital photo
- Terabyte = 1024 GB = external hard drive capacity ( 1 trillion bytes)
- Multimedia software
- Advantages
- Easy to
standardise
slides
- Can save
presentations
on hard drive
- edit order of slides
- Special effects
and sound can
be added
- templates can be used
- Disadvantages
- Relies on computer
- training required
- computer can be
unrealiable (crash)
- Expensive
equipment, people
want to steal it
- Difficult ot annotate
