Cloud computing and Ubiquitous
computing systems Callum pilling
Ubiquitous means ‘existing everywhere’. Processors can be embedded
in any device, including clothing, appliances, vehicles, buildings and people,
to connect them to the internet so that the data generated by the
processors will be readily available.
Radio frequency identification (RFID)
The RFIDs register when any product leaves the
premises.
Some futuristic examples of ubiquitous computing
include:
a car that can inform the owner when it needs servicing, book
itself into the garage and place orders for any parts needed
a refrigerator that can monitor its contents, compile an order as
food is used and add the items to the user’s online shopping
account.
An example of a use of RFID is the cat flaps that only open for
the animal that has the correct chip in its collar
Applications of ubiquitous computing
Currently, there are computing
systems in place which monitor
the shelf and warehouse stock.
This technology is used by many
industries (supermarkets, book
and DVD suppliers, car part
manufacturers, etc)
When the stock reaches a certain minimum
level, an order is automatically placed with the
appropriate supplier electronically. Mainly this
is done by a process where the tills feed
product sales to a central computer, which
then calculates the present stock.
Currently manual checks still have to be
made to allow for ‘shrinkage’ (i.e. loss due to
theft or damage).
Cloud computing – This is when a computer
uses services provided by another
organisation’s computer systems.
Servers – A computer hardware system
which acts as a host for other computers on
the same network
Cloud storage – This is when a computer’s
storage, access and retrieval facilities are hosted
by another computer system.
Radio frequency identification (RFID) – The use of a
wireless non-contact system which uses radio waves
to transfer data from a tag attached to an object or
person. The technology is mainly used for the
purposes of automatic identification and tracking.
