Answer:
- ADSL.
- Ethernet Home Networks.
- Fiber Optics.
- Cable Television.
Explanation:
In Computer, Guided media also known as bounded media involves the use of cable such as fibre-optic cables, coaxial cable to transmit data signals from one system device to another.
Examples of systems using guided media are;
- ADSL.
- Ethernet Home Networks.
- Fiber Optics.
- Cable Television.
Answer:
False
Explanation:
NPV stands for Net Present Value, it is an important term in finance as it used to determine the value of money or investment based on a series of cashflows and specified discount rate. Excel provides a functions which aids easy calculation of the Net Present value of money or investment using the NPV formula. The syntax forbthe NPV formula is :
=NPV(rate,value 1, [value 2],...)
This formular requires only tow key parameters ; the discount rate, which comes first and the cashflows, which is designated in the syntax as values ; the cashflows is usually placed in a range of cells in excel and the cell range is inputed in the formular. Hence, the number of payments and future value aren't part of the NPV syntax.
Answer:
Option 1: May crash at runtime because it can input more elements than the array can hold
Explanation:
Given the code as follows:
- int[] a = {1, 3, 7, 0, 0, 0};
- int size = 3, capacity = 6;
- int value = cin.nextInt();
- while (value > 0)
- {
- a[size] = value;
- size++;
- value = cin.nextInt();
- }
From the code above, we know the <em>a</em> is an array with six elements (Line 1). Since the array has been initialized with six elements, the capacity of the array cannot be altered in later stage.
However, a while loop is created to keep prompting for user input an integer and overwrite the value in the array started from index 3 (Line 4- 9). In every round of loop, the index is incremented by 1 (Line 7). If the user input for variable <em>value</em> is always above zero, the while loop will persist. This may reach a point where the index value is out of bound and crash the program. Please note the maximum index value for the array is supposedly be 5.
Answer:
- def getData(a_dict, key_list):
- result = []
-
- for key in key_list:
- result.append(a_dict[key])
-
- return result
-
- result = getData( {"puffin": 5, "corgi": 2, "three": 3} , ["three", "corgi"])
- print(result)
Explanation:
Let's define a function <em>getData() </em>with two parameters,<em> a_dict </em>and <em>key_list</em> as required by the question (Line 1).
Since the function is to return a list of associated values of dictionaries, a new list,<em> result</em>, is declared and initialized with empty values (Line 2).
Next, use for-loop to traverse through every string in the input <em>key_list </em>(Line 4) and use the traversed key to address the value in the<em> a_dict </em>and add it to the <em>result</em> list (Line 5)
At last, return the <em>result </em>list as output (Line 7)
We can test the function using the test case from the question and we shall see the output as follows:
[3, 2]
