2. They have become important for people with
disabilities. Their flexibility allows adaptations
to be made easily to meet different needs,
making them easier to use. Accessibility
features are now a part of computer operating
systems and additional software and devices
can be added to extend the options available.
3. The motherboard is what holds all the components useful in the
computer e.g Hard drive and RAM. A printed circuit board
containing the principal components of a computer or other
device with connectors for other circuit boards to be slotted into.
For special needs children the motherboard would have to be
really powerful to run all the software needed. It might also need
lots of ports so you can add lots of peripherals.
4. RAM stands for ‘Random Access Memory’ which finds
places to store data randomly. It is not connected to the
computer but when you do connect it, RAM temporarily
stores data to the computer. On a computer you would
need at least 4GB-8GB of RAM with an extension up to
16GB.
A special needs computer would need a lot of RAM
because it will hold special needs programmes such as
dyslexia software, communications software and eye gaze
software.
5. A heat sink draws heat away from a CPU the
heat sink has a thermal conductor that carries
heat away from the CPU into fins that help
provide a large surface area for the heat to
dissipate through out the rest of the computer.
6. A hard drive is a disk drive used to read from and write to a hard
disk. Data sent to and from the hard drive is interpreted
by the Disk controller, which tells the hard drive what to
do and how to move the components within the drive.
A hard drive usually consists of 300gb – 1 tb.
7. Book reader – allows children to hear what has
been written.
Keyboard – a keyboard with large lettering and
has colours this will able children with special
needs use a keyboard.
A BIGTrack – a sensory mouse allows children
to still use computer mouse but with palm of
their hand.
