Major Impacts of ICT Development
- Reduction in size of ICT devices by micro circuitry
- Increase in processing power
- New methods of storage such as flash memory - increases data portability
- Advances in telecommunication - allowed data to be transfered instantly across the world or locally via wireless
- Businesses can keep in touch with their employees via portable computers and mobile phones
- A few years ago, a business traveller could use a laptop to produce documents, a mobile to make calls and a PDA for short notes and contact details
- Devices are now used with phones, cameras, address books, music players and internet connectivity. The previous devices are converging into one.
- Although devices have gotten smaller, they are starting to get bigger again so the user can use the device for emails and web browsing etc.
- The idea that users could interact with a range of devices that work together seamlessly, without the user knowing. e.g. clothes could have tags so that the washing machine knows how to wash them
- Each item would need an individual ID provided by an RFID (Radio Frequency Identification) - could be used in mobile phones to pay for items, like an Oyster Card.
- Visual barcodes or 'tags' can be used as another form of identification
- Semacodes can be downloaded an printed, and can be photographed by a mobile phone, which will transport the user to a companies website.
- GPS (Global Positioning System) can be used to track devices and items for security
- there are also issues of personal privacy
- The most powerful computers in the world are known as 'Supercomputers'
- Designed to carry out calculations extremely quickly
- Speed is measured in 'flops' (floating point operations per second)
- 2008 the worlds first petaflop computer was announced
- Can be used to model weather, cliamte, and the performance of new drugs
- Some devices are being designed to read the eletrical signals from the brain via electrodes that rest on a humans scalp
- The electrodes monitor tiny changes in electrical voltage, from which software interprets them to attempt to identify what the user is thinking
- Could be extremely beneficial to people with disabilities
- Better results could be produced is the electrodes were 'invasive' to the brain, but this could be dangerous
- Explorers the effects of human genes on health, enabling scientists to identify hereditary traits, and predict the liklihood of future illness
- NASA are working on developing unmanned probes that could be sent to the moon, to communicate back to earth.
- However, there are issues with powering the probes
- Solar would not work, as the probes could be in darkness for up to 14 days.
- Nuclear power is being considered
