Implement the method countInitial which accepts as parameters an ArrayList of Strings and a letter, stored in a String. (Precondition: the String letter has only one character. You do not need to check for this.) The method should return the number of Strings in the input ArrayList that start with the given letter. Your implementation should ignore the case of the Strings in the ArrayList. Hint - the algorithm to implement this method is just a modified version of the linear search algorithm. Use the runner class to test your method but do not add a main method to your U7_L4_Activity_One.java file or your code will not be scored correctly.

Answer:

a. Packets - Network layer

b. Segments - Transport layer

c. Bits - Physical layer

d. Frames - Data link layer

Explanation:

When TCP/IP protocols are used for communication between two network hosts, there is a process of coding and decoding also called encapsulation and decapsulation.

This ensures the information is not accessible by other parties except the two hosts involved.

Operating Systems Interconnected model (OSI) is used to standardise communication in a computing system.

There are 7 layers used in the OSI model:

1. Session Layer

2. Transport Layer

3. Network Layer

4. Data Link Layer

Answer:

Explanation:

From the given information:

[tex]a_{n-1} , a_{n-2}...a_o[/tex] in binary is:

[tex]a_{n-1}\times 2^{n-1} + a_{n-2}}\times 2^{n-2}+ ...+a_o[/tex]

So, the largest number posses all [tex]a_{n-1} , a_{n-2}...a_o[/tex]  nonzero, however, the smallest number has [tex]a_{n-2} , a_{n-3}...a_o[/tex] all zero.

∴

The largest = 11111. . .1 in n times and the smallest = 1000. . .0 in n -1 times

i.e.

[tex](11111111...1)_2 = ( 1 \times 2^{n-1} + 1\times 2^{n-2} + ... + 1 )_{10}[/tex]

[tex]= \dfrac{1(2^n-1)}{2-1}[/tex]

[tex]\mathbf{=2^n -1}[/tex]

[tex](1000...0)_2 = (1 \times 2^{n-1} + 0 \times 2^{n-2} + 0 \times 2^{n-3} + ... + 0)_{10}[/tex]

[tex]\mathbf {= 2 ^{n-1}}[/tex]

Hence, the smallest value is [tex]\mathbf{2^{n-1}}[/tex] and the largest value is [tex]\mathbf{2^{n}-1}[/tex]

Explanation:

Answer:

Explanation:

The following code is written in Python. It is a function that takes the three arrays as parameters. It loops over the first array comparing to see if a number exists in the other arrays. If it finds a number in all three arrays it adds it to an array called same_elements. Finally, it prints the array.

def has_same_elements(arr1, arr2, arr3):

   same_elements = []

   for num1 in arr1:

       if (num1 in arr2) and (num1 in arr3):

           same_elements.append(num1)

       else:

           continue

   print(same_elements)

Answer:

mkdir homeworks    // make a new directory called homeworks.

touch homework_instructions.txt //create a file called homework_instruction

sudo -i    // login as root user with password.

chmod u+rwx homework_instructions.txt  // allow user access all permissions

chmod go-wx homework_instructions.txt // remove write and execute permissions for group and others if present

chmod go+r homework_instructions.txt  // adds read permission to group and others if absent.

grep POINTS homework_instructions.txt | ls -n

Explanation:

The Linux commands above first create a directory and create and save the homework_instructions.txt file in it. The sudo or su command is used to login as a root user to the system to access administrative privileges.

The user permission is configured to read, write and execute the text file while the group and others are only configured to read the file.

Answer:

The SANS Top 20 Critical Security Controls For Effective Cyber Defense

Explanation:

Password/PIN Policy

Developing a password and personal identification number policy helps ensure employees are creating their login or access credentials in a secure manner. Common guidance is to not use birthdays, names, or other information that is easily attainable.

Device Controls

Proper methods of access to computers, tablets, and smartphones should be established to control access to information. Methods can include access card readers, passwords, and PINs.

Devices should be locked when the user steps away. Access cards should be removed, and passwords and PINs should not be written down or stored where they might be accessed.

Assess whether employees should be allowed to bring and access their own devices in the workplace or during business hours. Personal devices have the potential to distract employees from their duties, as well as create accidental breaches of information security.

As you design policies for personal device use, take employee welfare into consideration. Families and loved ones need contact with employees if there is a situation at home that requires their attention. This may mean providing a way for families to get messages to their loved ones.

Procedures for reporting loss and damage of business-related devices should be developed. You may want to include investigation methods to determine fault and the extent of information loss.

Internet/Web Usage

Internet access in the workplace should be restricted to business needs only. Not only does personal web use tie up resources, but it also introduces the risks of viruses and can give hackers access to information.

Email should be conducted through business email servers and clients only unless your business is built around a model that doesn't allow for it.

Many scams and attempts to infiltrate businesses are initiated through email. Guidance for dealing with links, apparent phishing attempts, or emails from unknown sources is recommended.

Develop agreements with employees that will minimize the risk of workplace information exposure through social media or other personal networking sites, unless it is business-related.

Encryption and Physical Security

You may want to develop encryption procedures for your information. If your business has information such as client credit card numbers stored in a database, encrypting the files adds an extra measure of protection.

Key and key card control procedures such as key issue logs or separate keys for different areas can help control access to information storage areas.

If identification is needed, develop a method of issuing, logging, displaying, and periodically inspecting identification.

Establish a visitor procedure. Visitor check-in, access badges, and logs will keep unnecessary visitations in check.

Security Policy Reporting Requirements

Employees need to understand what they need to report, how they need to report it, and who to report it to. Clear instructions should be published. Training should be implemented into the policy and be conducted to ensure all employees understand reporting procedures.

Empower Your Team

One key to creating effective policies is to make sure that the policies are clear, easy to comply with, and realistic. Policies that are overly complicated or controlling will encourage people to bypass the system. If you communicate the need for information security and empower your employees to act if they discover a security issue, you will develop a secure environment where information is safe.

elif computer == 2:

   if user == 0:

       print("The computer is paper. You are scissor. You won")

   elif user == 1:

       print("The computer is paper. You are rock. Computer won")

   elif user == 2:

       print("The computer is paper. You are paper too. It is a draw")

Explanation:

*The code is in Python.

Import the random to be able to generate number number

Generate a random number between 0 and 2 (inclusive) using randint() method and set it to the computer variable

Ask the user to enter a number and set it to the user variable

Check the value of computer the computer variable:

If it is 0, check the value of user variable. If user is 0, it is a draw. If user is 1, user wins. If user is 2, computer wins

If it is 1, check the value of user variable. If user is 0, computer wins. If user is 1, it is a draw. If user is 2, user wins

If it is 2, check the value of user variable. If user is 0, user wins. If user is 1, computer wins. If user is 2, it is a draw

From the available options given in the question, once the while loop terminates any of the provided answers could be correct. This is because the arguments passed to the while loop indicate two different argument which both have to be true in order for the loop to continue. All of the provided options have either one or both of the arguments as false which would break the while loop. Even options a. and b. are included because both would indicate a false statement.

Answer:

The answer is "[tex]\bold{A \cap\ B=\phi}[/tex]"

Explanation:

let

[tex]A=\{1,2,3\}\\\\B=\{4,5,6\}[/tex]

A and B are disjoint sets and they are not an empty set  then:

[tex]A\cup\ B=\{1,2,3,4,5,6\} \\\\A\cup\ B\neq 0[/tex]

therefore if the intersection of the two non-empty sets is the empty set then its disjoint set, which is equal to [tex]\bold{A \cap\ B=\phi}[/tex].

Explanation:

A perpetual system of inventory can be defined as a method of financial accounting, which involves the updating informations about an inventory on a continuous basis (in real-time) as the sales or purchases are being made by the customers, through the use of enterprise management software applications and a digitized point-of-sale (POS) equipment.

Under a perpetual system of inventory, updates of the journal entry for cost of goods sold or received would include debiting accounts receivable and crediting sales immediately as it is being made or happening.

Hence, an advantage of the perpetual system of inventory over the periodic system of inventory is that, it ensures the inventory account balance is always accurate provided there are no spoilage, theft etc.

The following are the characteristic of a perpetual inventory system;

I. It is the most popular choice for modern business.

II. Inventory is updated in near real-time.

III. It provides up-to-date balance information and requires fewer physical counts.

Explanation:

The following program is written in Python. It first creates a method that reverses the array using the built in reverse function. Then it creates the array, creates a loop to ask the user to enter 12 numbers while passing each input into the array. Finally, it passes that array into the previously created reverse method and prints out the new array.

def reverse(num_arr):

   num_arr.reverse()

   return num_arr

num_arr = []

for x in range(12):

   num = input("Enter a number")

   num_arr.append(num)

print(reverse(num_arr))

Answer:

b. Person p = new Person ("Homer", 23);

Explanation:

The statement that will create an object that represents an adult person would be the following

Person p = new Person ("Homer", 23);

This statement creates a Person object by called the Person class and saving it into a variable called p. The Person method is called in this object and passed a string that represents the adult's name and the age of the adult. Since the age is greater than 18, the method will return that adult = true.

The other options are either not passing the correct second argument (needs to be an int) or is passing an int that is lower than 18 meaning that the method will state that the individual is not an adult.

Answer:

Explanation:

Its the exact definition of an undecidable problem. Plus I have my notebook open next to me and that's what it says, trust bro.

An undecidable problem is a problem for which no algorithm can be constructed that always produces a correct output. The correct option is D.

Problems that cannot be solved by an algorithm are known as undecidable problems since no computer program can come up with a solution that works for every scenario.

This is a key drawback of computing systems, and it has been analytically shown that some issues are intractable from the start.

Decision issues that lack an algorithmic solution are referred to as undecidable.

A issue that cannot be solved by a computer or computer software of any type has never been solved by a computer. There is no such thing as a Turing machine that can solve an insoluble problem.

Thus, the correct option is D.
