& Computers work faster than humans can.
& A wide range of time-consuming tasks can be performed on a
bigger scale
Work
& Computers have reduced the labour involved in mentally intensive
and repetitive physical tasks
& They can also perform tasks that can be dangerous for people
to perform on their own.
Resources
& Resources cost money and computers can be programmed to
work more efficiently with resources.
& Technology can also be used to monitor and limit carbon
emissions in factories and cars, to keep the air we breathe
cleaner.
ACCURACY: & As long as computers have quality programs and quality data, it is
extremely accurate. Repeatable accuracy is essential in mass
production on assembly lines
& If the software is correct, the computer can perform the same
tasks over and over with 100% accuracy.
What aspects ensure that computers are accurate?
application programs + data = high quality
RELIABILITY: & Computers can be relied on to do tasks accurately, without getting
tired, getting bored, complaining, or asking for more money.
& Computers help us to record and use data efficiently. Computers
do this by allowing users to work in an organized and competent
way. This way a user can get a lot of work done with little effort
& Efficient data entry is aided by accurate data entry. Accurate
data entry is aided by the use of data validation techniques such as
input masks and validation rules.
& Computers process data reliably. As long as users enter the data
accurately, the computers can be relied upon to provide accurate
output. Computers do not have to take leave for vacations or even
for sleep. The 'garbage in, garbage out' (GIGO) principle refers to
the fact that inaccurate inputs will result in inaccurate outputs.
