Accuracy
Accuracy is a quality that describes anything near its true value or a recognized standard. For example, if a person's actual weight is 175.2 pounds, a scale that displays "174.8" would be considered accurate as it's close to the true value. The following sections contain answers to questions frequently asked about accuracy.
Are computers 100% accurate?
No, computers are not 100% accurate because they're programmed by humans, who are prone to mistakes (even when careful). Consequently, computers can never be 100% accurate by all measures. Also, a computer relies on user input; if the user gives incorrect input, it responds with the incorrect output. This action is called GIGO (garbage in, garbage out).
All of that said, when programmed correctly and tested thoroughly, computers can be more accurate than humans at most tasks; that's why they're so prolific today across many industries. Additionally, programmers can add error checking to help ensure the user's input is correct so that a correct response is received. For example, when entering a search query containing a spelling error (e.g., "compoter mouse"), the search can autocorrect the spelling error to ensure results are accurate.
How does accuracy help with computer development?
When computer software is developed, accuracy helps with the following:
- Reduces the number of bugs or errors a program contains.
- Reduces the need for patches or other problem-fixing updates.
- Improves the reliability of the program and reduces the risk of crashes.
- A well-designed program has better overall performance.
- Improves security; inaccuracies in the code cause most security vulnerabilities.
- Prevents data loss or corruption.
- Helps with troubleshooting when problems arise.
How can a computer help my accuracy?
Computers can assist their users in being more accurate by anticipating and recognizing common errors. Below are a few examples of how a computer can improve your accuracy.
- A spell checker helps find spelling errors and can automatically correct them or suggest alternative spelling options.
- A grammar checker helps writers by looking for common grammatical mistakes and offering suggestions for improvement.
- A calculator helps you perform calculations quickly and without errors.
- CBT (computer-based training) programs and services can also train you and test your skill on many tasks, improving your accuracy at what's being taught.
How can I improve my typing accuracy?
Like any skill, your typing accuracy on a keyboard can be improved by continual practice. The pages linked below contain information on improving your typing.
How is typing accuracy calculated
NWAM (net words a minute) is a measurement used to determine the GWAM (gross words a minute), minus any errors.
Should I focus on accuracy or speed?
Focusing more on your typing accuracy rather than only how fast you type helps reduce the number of mistakes you make. Also, reducing mistakes increases your speed because less time is spent correcting them.
