- What is the difference between standardisation and normalisation? And can you offer some instances of each?arrow_forwardWhich of the studied data structures in this course would be the most appropriate choice for the following tasks? And Why? a. An Exam Center needs to maintain a database of 3000 students' IDs who registered in a professional certification course. The goal is to find rapidly whether or not a given ID is in the database. Hence, the speed of response is very important; efficient use of memory is not important. No ordering information is required among the identification numbers. b. A transposition table is a cache of previously seen positions in a game tree generated by a computer game playing program. If a position recurs via a different sequence of moves, the value of the position is retrieved from the table, avoiding re-searching the game tree below that position.arrow_forwardWalk me through the basic procedures involved in the segmentation process. How does it differ from paging? Simply put, what does it mean to state that something has been compacted?arrow_forward
