1.
ReplyDeleteSpeed
Computers perform tasks very fast. Some cpu's can execute literally 'billions' of instructions per second.
Bank note counters perform repetitive tasks
Fingerprints can be matched quickly in a database
Programmed robots carry out jobs fast and accurately
2.
Accuracy
If programmed properly, computers are capable of performing the same tasks 100% accurately every time.
For example, a robot that is programmed to bolt a wheel to a car will get it exactly right each time.
3.
Multi-Tasking
Computers are able to perform many tasks at the same time.
4.
Repetitive
Tasks
Computers will carry out boring and repetitive tasks accurately. Humans tend to get bored and make mistakes.
For example, machines that count bank notes will do that job all day long without making a mistake.
5.
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.
6.
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.
7.
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.
8. Security
Data can be secured with passwords or encryption
