Answer:
In a sentence: data is raw numbers, while information is organized data.
Explanation:
Data is a series of numbers or facts. A data set is a collection of data that are related (for examples all the students result in your last math exam). But it's not organized by itself... and rarely mean anything when looked at it in a raw manner.
To make sense of a data collection, you have to analyze it, calculate the mean or median of the data set for example... this is a treatment that has to be done to a data set to give it significance.. after such analysis, the result you have (mean, median, etc..) is a piece of information devired from the data.
Answer:
The first automatic digital computer has been designed by the English mathematician and inventor Charles Babbage. Babbage developed the Analytical Engine Plans for the mid-1830s.
Explanation:
- Babbage has developed the concept of a digital, programmable computer and was a mathematician, philosopher, inventor, and mechanical engineer.
-
Some regard Babbage as a "computer father"
-
The inventing of its first mechanical computer, the difference engine, is attributable to Babbage, which eventually resulted in more complex electronic designs, although Babbage's Analytical Engine is the main source of ideas for modern computers. He was described as the "prime" among the numerous polymaths of his century by his varied work in another field.

Answer:
True: In binary search algorithm, we follow the below steps sequentially:
Input: A sorted array B[1,2,...n] of n items and one item x to be searched.
Output: The index of x in B if exists in B, 0 otherwise.
- low=1
- high=n
- while( low < high )
- { mid=low + (high-low)/2
- if( B[mid]==x)
- {
- return(mid) //returns mid as the index of x
- }
- else
- {
- if( B[mid] < x) //takes only right half of the array
- {
- low=mid+1
- }
- else // takes only the left half of the array
- {
- high=mid-1
- }
- }
- }
- return( 0 )
Explanation:
For each iteration the line number 11 or line number 15 will be executed.
Both lines, cut the array size to half of it and takes as the input for next iteration.
