Final answer:
A stack of recently used activities is called a stack, which works on a Last-In, First-Out basis. This principle is applicable in various scenarios, from computing to estimating other physical quantities like masses and times.
Step-by-step explanation:
A stack of all recently used activities, sorted in the order in which they were used, is called a stack. In the context of computer science and technology, this is a data structure that operates on the principle of Last-In, First-Out (LIFO). The most recently added item is the first to be removed, which reflects the actual scenario of a stack of physical objects like books or plates.
Understanding the concept of a stack can help students learn how to estimate or manage data in different scenarios, not just in technology but also in everyday situations. Estimation strategies used in computing, such as considering the number of pages in the stack, can apply to estimating various physical quantities such as masses and times.
For example, if you wanted to estimate the time required to complete a task, you might think of the task as a stack of individual steps. Just as one would count the number of pages to estimate the size of a physical stack, you could estimate the time by adding up the time expected for each individual step. This concept bridges the gap between abstract data structures in computing and tangible real-world applications.
