System = {"10.10.10.1" : "windows 10"} is a dictionary, which is a type of data structure that stores information in key-value pairs. This type of data structure is often used in programming languages such as Python and JavaScript. It can be used to store and retrieve data quickly, such as IP addresses and operating systems in this example.

The data structure systems is a dictionary, as indicated by the use of curly braces {} and the key-value pairs separated by colons :. Each key-value pair represents an entry in the dictionary, with the IP address as the key and the corresponding operating system as the value.

answer D another 100% provable incorrect answer provided by examtopics. Pretty sure they would fail the exam. might ask for a refund.

An example of a dictionary is a collection of key-value pairs, such as {'one':1, 'two':2, 'three':3}. An example of an array is a collection of elements stored in sequential order, such as [1, 2, 3]. An example of a tree is a hierarchical structure composed of nodes, such as the family tree. An example of a tuple is a fixed-length sequence of elements, such as (1, 2, 3).

D. A dictionary Explanation: • Tuple: A tuple in Python is an ordered collection of items that are immutable. Tuples are defined using parentheses () and can contain multiple elements. • Tree: A tree is a hierarchical data structure consisting of nodes, where each node has zero or more children nodes. Trees are not a built-in data structure in Python like lists or dictionaries. • Array: An array is a collection of items stored at contiguous memory locations. Arrays are typically used to store elements of the same type. In Python, lists are used instead of arrays and are defined using square brackets []. • Dictionary: A dictionary in Python is an unordered collection of key-value pairs. Dictionaries are defined using curly braces {} and are indexed by keys. Each key is mapped to a value.

The data structure in the given code is a dictionary, which maps IP addresses to operating system names. The syntax for creating a dictionary in Python is using curly braces {} and separating keys and values with colons (:), and separating items with commas (,). Therefore, the correct answer is: D. A dictionary

I think Anarry is correct

A - tuple. Tuple is an ordered set of values separated by a comma.
