Ubiquitous Computing System


Ubiquitous Computing Systems (Ubicomp)

1.     Definition of Ubiquitous Computing

Ubiquitous computing, also known as ‘exists everywhere’, is where processors can be put in any device, format or location in order to connect the internet so data will be generated by that processor and will be already available.


2.     Definition of RFID

RFID, also known as radio frequency identification, is where an object within a ubiquitous computing location contains RFID chips. This means the radio waves can transfer data to a tag a person or object so it can be tracked.

 
3.     How does a RFID work?

In a ubiquitous computing environment, a RFID chip is placed in a processor which enables data to be transferred and transmitted electronically as effectively as possible. These chips are generally placed on an object or person so it can be tracked down, but it isn’t like a GPS. It just monitors the amount of stock available, examples of this include:

Tags on groceries in the supermarket so when the data reaches a minimum number of quantities an automatic order will be sent out by the processor. RFID’s are similar to barcodes but do not need to be scanned and can transfer data electronically and be transmitted.

 
4.     What are 2 examples of ideas of unicomp being used now

·        Currently, unicomp is used generally on an everyday basis in many types of industries. Whether this is, motoring, supermarkets, clothing stores, and so on. If the shop is a CD store, then when the amount of CD’s are down to a certain number, the processor then automatically sends out data for more CD’s to be replaced in an order.

·        Another example includes, if a cat flap opens, it’ll only open for the cat if the correct chip is in its collar so no other cats with no RFID chip in its collar can come in.


5.     What are 2 examples of unicomp being used in the future

·        If an RFID chip is placed on a car, then on that person’s device it can automatically transfer data about when their car needs servicing, an MOT, to book itself into the garage, if it’s low on petrol and place orders if a part in the car isn’t working or broken.  It may also send information to their nearest garage to book an MOT or so on.

·        Another example is when a refrigerator is low on stock of food, and it automatically sends out an order to a supermarket for another order of that food to be sent in when it’s on a low quantity. The data will be sent out to the online website of the most common used supermarket.


6.     What does the acronym RFID stand for and what is it used for? (6)

RFID stands for radio frequency identification and is frequently used in ubiquitous computing, as it appears everywhere at the same time on any device. RFID is used for monitoring the information in industries, mainly in a ubiquitous computing environment, but also so everyone can connect to the internet or mobile device at the same time. It works in the RFID system, by having a RFID chip (radio frequency identification) installed into a processor, which then enables information to be transferred and transmitted through signals in the antenna. It’s used now on an everyday basis as the shopping industries use ubiquitous computing to keep track of the amount of stock in stores, and if a minimum number of that product is in place then an automatic order is placed. It can be used in the future by perhaps putting a RFID chip on a vehicle so it can transfer data about if the vehicle needs a MOT, servicing, is low on petrol or if it needs a spare part, for example.
