Describe a situation in which you have experienced harm as a consequence of a failure of computer security. Was the failure mali
Andrei [34K]

Answer: The goals of computer security are to protect computers and users from data theft or loss as well as damage to any part of the computer.

Explanation: Common means of achieving computer security are firewalls, anti-virus software and this can fail due to hardware problems  or   weaknesses that prevent malicious attacks.

To answer this question, think of a time when you experienced any one of these. For example, personally, I was once an unfortunate victim of a general malicious attack that took advantage of a weakness in my anti-virus software. After clicking on a link on a dodgy website, a virus was installed on my computer. My computer finally crashed, without any hope of restarting it. I lost all my data and I had to buy a new computer.  This was a malicious attack.

However, sometimes people can be specifically targeted to steal their data or monitor their activities.

Discuss whether design considerations need to change for each kind of computer users. support your answer with an example.
vaieri [72.5K]
Each kind of computer users have different knowledge, needs and requirements. For example there is a difference between the computer knowledge of developers and users without <span>technical experience. Because of this, but also why they need and use computers, and what tools they need, design consideration need to change for each kind of computer users.</span>

Which formula is used to measure accuracy?
Westkost [7]

Answer:You can only find REaccuracy if you know the actual “true” measurement… something that's difficult to do unless you're measuring against the atomic clock. The formula is: REaccuracy = (Absolute error / “True” value) * 100%.
