Answer:
The correct answer is option (A).
Explanation:
Pinterest has turned to amazon for storage as a service because it continuously needs a large amount of storage as given in the scenario.
While the other options are not correct because of the following reasons:
- Grid computing can be defined as the concept of connection between a large number of computers in an architectural way who work to obtain the same goal but grid computing can not fulfill the need for storage for Pinterest.
- Cloud computing can work as data storage which can be accessed from the internet anywhere but this can not fulfill the storage requirements for Pinterest as they are very huge.
- Infrastructure as a service is not correct because the need of the company is for storage.
Depends on what software you use and how you set it up. But yea it’s possible
Answer:
i) The time taken for 1500 records = 15 seconds.
ii) The time taken for 1500 records = 50 seconds.
Explanation:
A is an O(n) algorithm.
An algorithm with O(n) efficiency is described as a linearly increasing algorithm, this mean that the rate at which the input increases is linear to the time needed to compute that algorithm with n inputs.
From the question, it is given that for 1000 records, the time required is: 10 seconds.
Algorithm time taken is O(n)
Hence,
1) For 1,500 records
=> 10/1000 = x/1500
=> 10x1500/1000 = x
x = 15 seconds
Thus, the time taken for 1500 records = 15 seconds.
2) For 5,000 records
=> 10/1000 = x/5000
=> 10x5000/1000 = x
x = 50 seconds
Thus, the time taken for 1500 records = 50 seconds.
