Answer:
The term "savanna" is often used to refer to open grassland with some tree cover, while "grassland" refers to a grassy ecosystem with little or no tree cover.

Answer:
polynomial-bounded algorithms
Explanation:
There are two algorithm complexities and they are time and space complexities. They can be denoted with the big-O notation. The big-o notation for a time and space complexity gets the worst-case time and space respectively.
The time complexity gets the measure of the execution time of an algorithm. When the time function is a polynomial ( k^n + k^n-1 ...) then the algorithm is said to be a polynomial-bounded algorithm.
Answer:
This is a failure of prevention model of computer security
Explanation:
Because the firewall was misconfigured so attack prevention mechanism failed to resist the attack and the security of computer is compromised. Prevention is an important model of operational security because <em>protection </em>is possible firstly attacks are prevented from targets and if not prevented and failed then they are detected and finally security department respond to that attack.
protection = <em>prevention </em>if <em>prevention </em>failed than (detection+response)
