The input function reads a piece of data that has been entered at the keyboard and returns that piece of data, as a string, back to the program. This function is designed to accept data directly from the user, Similar function is the function raw_input() used in Python programming, which asks the user for a string of data (ended with a newline), and simply returns the string.
Answer:
The answer is d. Data
Explanation:
information gathered from observing a plant grow 3 cm over a two-week period results in Data
data is facts and statistics collected together for reference or analysis.
Data is any information that has been collected, observed, generated or created to validate original research findings
a cloud phone system is a Voice over IP (VoIP) based business telephoneplatform that is hosted by a third-party provider such as OnSIP. Cloud phonesystems typically offer advanced security and telephony features such as: extension dialing, auto attendants, and conference bridges

See explaination
Explanation:
The reasons why indexed sequential search structure is better are:
1. In index sequential search any field of the records can be used as the key. This key field can be numerical or alphanumerical.
2. Since each record has its data block address, searching for a record in larger database is easy and quick. There is no extra effort to search records. But proper primary key has to be selected to make efficient.
3. This method gives flexibility of using any column as key field and index will be generated based on that. In addition to the primary key and its index, we can have index generated for other fields too. Hence searching becomes more efficient, if there is search based on columns other than primary key.
The reasons why 5 B-tree is better:
1.The B-tree Provides support for range of queries in an efficient manner and You can iterate over an ordered list of elements.
2. B-Tree algorithms are good for accessing pages (or blocks) of stored information which are then copied into main memory for processing. In the worst case, they are designed to do dynamic set operations in O(lg n) time because of their high "branching factor" (think hundreds or thousands of keys off of any node). It is this branching factor that makes B-Trees so efficient for block storage/retrieval, since a large branching factor greatly reduces the height of the tree and thus the number of disk accesses needed to find any key.
3. It is a generalization of a BST in that a node can have more than two children. These are self-balancing and hence the average and worst complexities is logarithmic. We opt for these when the data is too huge to fit in main memory. These structures are used in database indexing and help in faster operations on disk
the additional informations is we should first decide to choose which structure is suiatable for which algoritm in terms of space and time and then use the appropriate search algorithm.
