Answer:
The answer is E: All of the above
Explanation:
All of the above scenarios are examples of serious computer crimes. They are crimes that exist in the offline world but take place online. Sexual predators, for instance, mostly take advantage of the anonymity provided by the internet. They often target dating sites and find suitable victims. Cyber bullying and Cyber stalking are just as harmful as any other computer crime. Industrial Espionage may also somehow fall into this category. Less frequently, criminals may steal documents and computer files or more often, illegally gain access to company’s trade secrets on computers and servers.
Answer:
well, as long as there are no right or wrong answers, don't:
look to closely at the screen, as it may mess up your eyes
hold a drink above the computer, as it may spill and cause "sticky keys"
go to sites that you know will give your a computer a virus, cause they cost hundreds of dollars to repair, and some aren't able to come out
go on illegal sites/do illegal operations to the computer itself, because then you won't have a computer
Explanation:
Let me re-write the proposition:
p↔q⊕(¬p↔¬r)∧¬q.
Generally, the number of rows in a truth table depends on the number of Variables. Here we have 3 Variables: p,q and r. Each of them can have either the value of 1 or 0, which gives us 2*2*2 possibilities, or 2³, that is 8 possibilities and 8 rows:
p=0, q=0, r=0
p=0, q=0, r=1
p=0, q=1, r=0
p=0, q=1, r=1
p=1, q=0, r=0
p=1, q=0, r=1
p=1, q=1, r=0
p=1, q=1, r=1
All of the answers above are correct
