What things do ICT devices do well?
ICT devices and systems are
capable of performing lots of tasks very well. Some of these are listed below:
- Speed
Computers perform tasks very fast. Some cpu's can execute literally
'billions' of instructions per second.
- Accuracy
If programmed properly, computers are capable of performing the same tasks
100% accurately every time.
- Multi-Tasking
Computers are able to perform many tasks at the same time.
- Repetitive Tasks
Computers will carry out boring and repetitive tasks accurately. Humans
tend to get bored and make mistakes.
- Networking
Computers can be joined together (either as a LAN or a WAN) and allows
them to easily share resources such as printers and data.
- Huge amounts of
Data Storage Computer databases can store
enormous amounts of data. All types of data be stored including text,
numbers, images and video.
- Fast Searches
Computers can search for stored data extremely fast. For example, the
police can match fingerprints in a database in minutes rather than
spending weeks searching through printed copies.
- Security
Data can be secured with passwords or encryption.
What things do ICT devices not do well?
Computers, and other
devices, are not without their problems. Limitations of ICT devices are listed
below:
- Battery Life
Portable device such as laptops, PDAs and mobile phones are limited by
their battery life. These devices only remain charged for so long before
they need to be plugged into the mains.
- Weight
Some portable devices are heavy (especially laptops). This does not make
them ideal for carrying around.
- Screen and
Keyboard Size Smaller devices such as mobile
phones and PDAs have very small screens and keyboards which can cause
problems for some people.
- Bandwidth is the speed that data can be transported over the Internet. Low bandwidth means that large files will take a long time to transfer.
