a computer worm spreads from one computer to another through a.
Answers
SolutioN :-
Let the speed of the stream be x km/h.
so, speed of boat in downstream is ( 11 + x )
and also speed of boat in upstream is ( 11 - x )
Distance cover by boat is 12 km.
The speed of boat in still water is 11 km/h
\boxed{\tt \bullet \: \: \: Distance = Speed \times Time.}
∙Distance=Speed×Time.
\begin{gathered} \tt \rightarrow \dfrac{12}{11 - x} + \dfrac{12}{11 + x} = 2 \times \dfrac{3}{4} \\ \\ \end{gathered}

Answer:
where a worm differs from a virus is that it typically doesn't infect or manipulate files on its own .
Explanation:
simply clones itself over and over again and spreads via a network to other system where it continues to replicate itself.
