Suppose the inventory is unordered (!) and a sequential search is done to locate a specific artifact. Given that the search is e

lana [24]

Answer:

The computer can do 12000 searches per second. Suppose there are 60000 inventory items. And we need to search one item from it in a sequential manner. The computer can do 12000 searches in one second. Hence it can search in a list of 60000 inventory in 5 seconds, as 12000 x 5 =60000 searches, in the worst case. And if the item is below 12000 on the list, it will take less than 1 second(1/12000 sec in best case), and so on.

And if we assume that the list is sorted, and perform a binary search. then in the worst case, the number of searches required in the worst case will be 60000/2= 30000. And the time required will be 30000/12000= 5/2=2.5 seconds, and (1/24000) seconds in the best case. Its 1/24000 as its binary search.

Which of the following is a typical feature of forums but not of review sites?

kkurt [141]

Actually, two options are correct:

They allow private messaging. - this is your safest option, as review sites don't offer private messaging (many rewiews are anonymous, so that would kill the point), but all forums do.


You need to sign up to be a member
Actually, this is also true, as many, if not most forums do require you to sign up, so that it is visible whenever a certain person posts again - otherwise you won't know if you're talking to the same person! however, many review sites, for example reviewing doctors, let you post without signing in.
