Your company has been assigned the 194.10.0.0/24 network for use at one of its sites. You need to calculate a subnet mask that will accommodate 60 hosts per subnet while maximizing the number of available subnets. What subnet mask will you use in CIDR notation?
Answers
To accommodate 60 hosts per subnet while maximizing the number of available subnets, we need to use a subnet mask that provides enough host bits and subnet bits.
How to calculateTo calculate the subnet mask, we determine the number of host bits required to accommodate 60 hosts: 2^6 = 64. Therefore, we need 6 host bits.
Subsequently, we determine the optimal quantity of subnet bits needed to increase the quantity of accessible subnets: the formula 2^n >= the amount of subnets is used. To account for multiple subnets, the value of n is set to 2, resulting in a total of 4 subnets.
Therefore, we need 2 subnet bits.
Combining the host bits (6) and subnet bits (2), we get a subnet mask of /28 in CIDR notation.

They got lower rates from the railroads than small farmers did. The correct option is A.
What is bonanza farm?Bonanza farms were large-scale commercial farms that emerged in the United States in the late nineteenth century.
These farms were typically located in the Great Plains region and focused on mass production of a single crop, such as wheat or maize.
One of the primary ways that bonanza farms made it difficult for small farmers to compete in the late nineteenth century was by receiving lower railway rates than small farmers.
Due to the large volume of goods shipped, bonanza farms were large-scale commercial farms that typically produced a single crop, such as wheat, and they were able to negotiate lower shipping rates with railroads.
Thus, the correct option is A.

Using a K-Map, simplify the sum of the minterms.
Answers
Karnaugh Map or K-Map is a pictorial method used to simplify Boolean algebra expressions and produce a minimized version of a given truth table and the simplified expression is D(B+AC)+D(AC+C) + BD.
Karnaugh Map or K-Map is a grid-like representation of truth tables that enables the user to identify patterns that correspond to logical operations of the Boolean variables.
K-Maps are useful tools for simplifying Boolean expressions.
They provide a graphical method of representing a Boolean function's truth table that simplifies the process of reducing the function using Boolean algebra.
The following steps are used to simplify the sum of the minterms using K-Map:
Construct the K-Map. In this case, since the function is a sum of minterms, we are given that the output is high whenever A=0, B=1, C=0, D=0, A=1, B=1, C=0, D=0, A=0, B=1, C=1, D=0, A=1, B=1, C=1, D=0, A=1, B=0,C=1, D=1, and A=0, B=1, C=1, D=1.
These are the cells with 1 in the map.
Group the adjacent cells containing 1s in groups of 2, 4, or 8.
Convert the groupings into Boolean expressions.
Simplify the expressions by using Boolean algebra.
The K-Map for the given sum of minterms, the two groups can be converted into Boolean expressions as follows:
Group 1: BD+ACD+ABCD
Group 2: AC+BD+BCD
Simplify the Boolean expressions by using Boolean algebra.
Group 1: BD + ACD + ABCD = D (B+AC+ABC)
= D(B+AC)
Group 2: AC + BD + BCD = D(AC+B+C) + BD = D(AC+B+C+B)
= D(AC+C)
The simplified expression is D(B+AC)+D(AC+C) + BD.

QR
code! Specifications You will create a class
QRC
code that fills a grid with values that can be interpreted to visualize a QRCode image. (This is not a true QRCode but a pattern similar to one.) Required elements 1. QRCode class methods are instance methods. 2. Your program will contain a main method that creates an instance of QRCode and calls its methods such that the result output is a grid dim
x
dim with Finder values in the upper left, lower left, and upper right corners. 3. The dimension for the grid and the seed for the Random object must be passed in from the command line. 4. If two arguments are not passed in from the command line, your program should use constants defined below: - DEFAULT_DIMENSION 30 - DEFAULT_SEED 160 5. Methods that return a value must pass unit tests that will not be made available for view, that is, those methods should be thoroughly tested by you prior to submitting your program. 6. Only the print methods may have output to the console. 7. Class members must conform to the UML diagram below: Q=============== Class Name ================ QRCode ============ Private Variables ============ - grid : int[] [] ============ Public methods ============== + createPattern(dim : int, seed : int) : int[] + setGrid(dim : int, pattern : int []) : void + getGrid() : int[][] + setFinder(xpos : int, yPos : int) : void + addFinders(dimension : int) : void - fillSquare(startX : int, startY : int, width : int, color: int) : void // possible helper method + print() : void + print (pattern : int [] ) : void + print(matrix : int[][]) : void Method specifications You will create an outline called a stub program where the method headers are the only implemented part of the class and all methods only return default values. In a later lab, you will complete the class to have full functionality. You can get all the information you need from the UML outline above. Testing Things to test for are the correct number/type of arguments, and the return values (void or null).
