Would these statements cause an error? Why or why not? int year = 2019; int yearNext = 2020; int & ref = year; & ref = yearNext;

Answers

Answer 1

Answer: YES

Explanation:

int year=2019;

int yearNext=2020;

 int &ref=year;

&ref=yearNext; {This line leads to error as references cannot be reassigned}

(//compilation error: lvalue required as left operand of assignment

) lvalue(&ref) is not something which can be assigned.

To get this better, here are the difference between pointers and reference variables

Pointers

Pointers can be incremented

Array can be formed with pointers

Pointers can be reassigned

Pointer can be declared as void  

Reference variable

References cannot be incremented

Array cannot be formed with references

References cannot be reassigned as references shares the address of the variable its assigned

References can never be void

* Physical address in paired hexadecimal form.

* Physical address expressed in binary form.

Answer:

00000000 11111111 00000011 10111110 10001100 11011010

Explanation:

(i)First, open a command prompt window by using the shortcut: Windows key + X then select command prompt in the list.

(ii)Now type ipconfig/ all and press Enter. This will return a few information

(a) To get the Physical address in paired hexadecimal form, copy any of the Physical Addresses shown. E.g

00-FF-03-BE-8C-DA

This is the hexadecimal form of the physical address.

(b) Now let's convert the physical address into its binary form as follows;

To convert to binary from hexadecimal, we can use the following table;

cal address EtherAddr. What would happen if, when you manually added an entry, you entered the correct IP address, but the wrong Ethernet address for that remote interface

Answers

The arp command allows users to download and edit the Address Resolution Protocol cache.Whenever time a laptop's TCP/IP stack utilizes ARP to determine its Multimedia Access Control address after an IP address, it records the mappings in the ARP cache because the future ARP iterators proceed quicker.In this, when the Router removes the IP address from the Ethernet frame after receiving the destination IP address & uses ARP to determine the destination MAC address.The information is sent to the ethernet address; IP is on a higher layer, therefore this would be lost before the user stored their layer.That's why the solution in "all information would be lost".

The Address Resolution Protocol ARP cache maintained by ARP keeps a record of IP addresses and their corresponding Media Access Control, MAC address

The correct response to what would happen if the wrong EtherAddr is

entered into the arp-s InetAddr EtherAddr command is that;

The system will not be able to connect to the IP address linked to the wrong Ethernet address.

The reason the above response is correct is as follows:

Characteristics of the ARP protocol;

The ARP protocol is a protocol that has a high level of control such that

the reply is trusted and can be used to redirect traffic through spoofing of

the responses to ARP which are then stored in the cache.

Functioning of the arp -s InetAddr EtherAddr command;

The command arp -s InetAddr EtherAddr command inputs a manual entry

into the ARP cache that works to assign the inputted IP address in InetAddr

to the MAC physical address in EtherAddr.

The ARP provides the translation from physical MAC addresses of Layer 2

to  the IP address of Layer 3 by mapping the MAC address to the IP

address.

Solution:

What would happen if, when you manually added an entry, you entered the correct IP address, but the wrong Ethernet address for that remote interface is as follows;

When the wrong Ethernet address is entered in the arp -s command, the

IP-address is resolved as belonging to the wrong Ethernet  or MAC

address, and if the address does not exist, it will not be possible to

connect to the correct or desired IP address.

hard disk drive has 16 platters, 8192 cylinders, and 256 4KB sectors per track. The storage capacity of this disk drive is at most Select one: a. 32 GB. b. 128 GB. c. 128 TB. d. 32 TB.

Answers

Answer:

B

Explanation:

Here, we want to calculate the storage capacity of the disk drive.

We proceed as follows;

Per track capacity = 4 * 256 KB = 1024 KB = 1 MB

per platter capacity = 1 MB * 8192 = 8192 MB

total capacity = 16 * 8192 MB = 131072 MB

converting total capacity to GB,

1024 MB = 1 GB

thus, 131,072 MB to GB would be;

total capacity =131072/1024 = 128GB

Answer: D) Sharing best practices, lessons learned and other topics in a central place where the team can collaborate

Explanation: Knowledge sharing within a team is usually an important aspect of building a strong and efficient team. Acquiring knowledge usually comes from the experience gathered from previous projects, learning, or tips learned from various sources. Therefore, sharing knowledge is always a good way to ensure that what is gained is sustained by letting others know. Sharing and sustaining knowledge is most effective when transmitted or aired to a group of people usually a team gathered in an interactive setting which allows members to freely share experience and get feedback, views, or thoughts from other collaborators.

(Find the index of the smallest element) Write a function that returns the index of the smallest element in a list of integers. If the number of such elements is greater than 1, return the smallest index. Use the following header: def indexOfSmallestElement(lst): Write a test program that prompts the user to enter a list of numbers, invokes this function to return the index of the smallest element, and displays the index.

Answers

Answer:

Here is the function that returns the the smallest element in a list of integers

def indexOfSmallestElement(lst):

  smallest = lst.index(min(lst))

  return smallest

Explanation:

The function indexOfSmallestElement() takes a list of integers lst as parameter.

  smallest = lst.index(min(lst))

In the above statement two methods are used i.e. index() and min().

The first method index returns the index position of the list and the second method min() returns the minimum element of the list.

Now as a whole the statement min() first returns the smallest element in the list (lst) of integers and then the index() method returns the position of that minimum element of lst. At the end the index position of this smallest element in the list (lst) is stored in the smallest variable.

So lets say if we have a list of the following elements: [3,2,1,7,1,8] then min() returns the smallest element in this list i.e. 1 and index() returns the index position of this smallest element. Now notice that 1 occurs twice in the list and index() method only returns the the first index found in the list. So it returns the smallest index of the two index positions of 1 i.e 2. Hence the output is 2.

The test program is given below:

lst=list()  

num=int(input("Enter the list size: "))

print("Enter a list of numbers: ")

for i in range(int(num)):

  integers=int(input(""))

  lst.append(integers)

print("The index of the smallest element is: ")

print(indexOfSmallestElement(lst))

First the list named lst is created. After that the user is prompted to enter the size of the list which determines how many elements user wants to add to the list. num holds the size input by user. After that print statement displays the line"Enter a list of numbers: ". Next the for loop takes the integers from user num times. Suppose user want to enter 3 as list size then loop will take 3 elements from user. int(input("")) in this statement integer type input is taken from user using input() method. lst.append(integers)  statement is used to append these input integers into the list i.e. lst. print(indexOfSmallestElement(lst)) the statement calls the indexOfSmallestElement by passing lst to this method to return the index of the smallest element in the list of integers.

What are the differences between editing manually and editing digitally? What tools are used for each?

Answers

Answer:

Both manual and digital editing are concepts used in proofreading.

Manual editing is also called "hard proofreading" (or "hard proofing" for short). It is the process of proofreading, modifying or revising printed documents. In this type of proofreading, one would normally manually mark parts of the printed documents with editing materials such as ink, pen, marker e.t.c

Digital editing is also called "soft proofing". In contrast to manual editing, this type is done on digital documents. These documents include, but not limited to, DOC, txt, PDF, image, audio and video files.

Tools for editing manually are;

i. pen

ii. ink

iii. tipex

Tools for editing digitally are;

i. Photoshop application

ii. Text editors such as notepad++, Microsoft word

Proofreading has evolved in recent times as a result of advancements in technology. Now, manual proofreading has paved way for digital proofreading, which allows revising of PDF and  DOC files. The difference in both forms is as follows:

Manual Editing: In the process of revising or proofing printed documents, one would manually apply standard proofreading marks. Manual editing is also known as "Hard proofing", as the process requires proofreaders to mark the hard copies.

Digital Editing: In the process of revising or proofing digital documents i.e. PDF and DOC files, one would digitally apply the proofreading marks. Thus, corrections and edits are transferred electronically among authors, proofreaders. Digital editing is also known as "Soft proofing", as the process requires proofreaders to mark the soft copies i.e. without using any paper or pen.

There are a number of electronic tools and marks available for both techniques of

proofreading. Some tools used for manual proofreading include- deletion, capitalization, and  insertion, close-up, transpose.

Tools used in digital proofreading include- spell check, readability levels, trite expressions,  and comment, track changes.

gray

Explanation:

In the above method "find_color" is declared that uses the color variable as the parameter, inside the method a color variable is declared that convert method parameter value into the string and remove its brackets, and three variable "r,g, and b" is defined.  In this variable first, it splits parameter value and after that, it converts its value into an integer and uses the multiple conditional statements to return its calculated value.

if block checks the r, g, and b value it all value is equal it will return a string value, that is "gray" otherwise it will go to elif block. In this block, it checks the value of r is greater then g, and b if it is true it will return a string value, that is "red" otherwise it will go to another elif block.   In this block, it checks the value of b is greater then g, and r if it is true it will return a string value, that is "blue" otherwise it will go to another elif block.    In this block, it checks the value of g is greater then r and b if it is true it will return a string value, that is "green" otherwise it will go to another elif block.    In the other block, it checks r is equal to g or g is equal to b or r is equal to b, it will return the value, that is "yellow" or "teal" or "purple".

A technician is evaluating malware that was found on the enterprise network. After reviewing samples of the malware binaries, the technician finds each has a different hash associated with it. Which of the following types of malware is MOST likely present in the environment?

a. Trojan
b. Polymorphic worm
c. Rootkit
d. Logic bomb
e. Armored virus

Answers

Answer:

(b) polymorphic worm

Explanation:

A polymorphic worm can be compared with a chameleon. It changes its color so as to blend with the background of the surrounding to avoid being seen or caught. A polymorphic worm is a special type of worm that keeps changing its constituent features in order to avoid being detected. The most common way in which polymorphic worms hide their codes is by using encryption.

Polymorphic worms have two parts: the part that changes and the one that does not change. The part that changes include the characteristics of the worm such as encryption key, associated hash value e.t.c. The part that does not change is basically its functionality. Therefore, although the characteristics of the worm keep changing, its overall function remains the same.

E. An SLA guarantee of 60 minutes

The Recovery Point Objective tells how old a backup file must be before it can be  recovered by a system after failure.

Since the data in the failover systems described in this question must be backup and recovered after the failure, it will be important to include the Recovery Point Objective (RPO) in the Business Continuity Plan.

Since the failover systems must use back up data that is no older than one hour, the backup of the system data must be done at intervals of 60 minutes or less. Meaning that the maximum RPO is 60 minutes.

Note that RPO is more critical than RTO in data backup

Answers

Answer:

The answer is "Option b".

Explanation:

In the choice b, a public class "Employee" is declared, in which two private variables "name and salary" is declared whose data type is a string and double. At this, the class is accessible outside the scope but it variable accessible in the class only and the wrong choice can be defined as follows:

In choice a, datatypes access modifiers were different that's why it is wrong.In choice c and d both classes use a priavte access modifier, which means it can't accessible outside that's why it is wrong.

The terminal window wants to evaluate your current bash knowledge by using the ~/workspace/nested-directories folder:

a. cd into the nested-directories/nested-level-1/ directory by using an absolute path
b. cd into the nested-level-3/ directory by using a relative path
d. Move the entire ~/workspace/config/ directory to the nested-level-1/ directory

Answers

Answer:

a. cd into the nested directories/ nested - level - 1 / directory using an absolute path

Explanation:

The directory is a location on the hard disk, which is also called a folder. It contains the files and also contains the other directories called sub directories.

A path to a file is merged with a slash and determines the file or directory in the operating system. An absolute path is the location file or directory from the actual file system

The directory's absolute path starts with a slash, and all slashed in the directory separates the directions.

All directions in the absolute path are written on the left side. The last name in the path may belong to the file, and the pwd command can determine the current directory.

The relative path is the location of the file. It begins with the working directory. An absolute path is unambiguous and working with deeply nested directories.

There are two commands which are used such as

cd pwdcd is used for changing directorypwd is used for the working directory

We easily navigate the file system with the help of an absolute path.

What's the value of this Python expression? ((10 >= 5*2) and (10 <= 5*2))

Answers

Answer:

The Boolean value returned by that expression will be True

Explanation:

We have two logical statements in that expression:

Expression 1: (10 >= 5*2)

This can be read as: is 10 greater than or equal to 5 multipled by 2. This evaluates to true as 10 is equal to 5 * 2. Hence expression 1 returns true

Expression 2: (10 <= 5*2)

This can be read as: is 10 less than or equal to 5 multiplied by 2. This also evaluates to true as 10 is equal to 5*2. Hence expression 2 returns true.

Now between this two expression is the and operator which evaluates to true if and only if both logical expressions returnes true.

True and True ==> True

Since Expression 1 ==> True and Expression 2 ==> True

This means Expression 1 and Expression 2 ==> True which is the Boolean value returned by the statement

The value of the python expression ((10 >= 5*2) and (10 <= 5*2)) is True

The code will definitely return a Boolean value(True or False).

For the expression to be True , the two statements must be True. The AND gate returns True if the whole statement is True.

(10 >= 5*2) is True because 10 is equals to 5 × 2 = 10.

(10 <= 5*2) is True because 10 is equals to 5 × 2 = 10.

The two statements are True . Therefore,

True and True = True.

Answer:

def split_check(bill, people, tax_percentage = 0.09, tip_percentage = 0.15):

   tip = bill * tip_percentage

   tax = bill * tax_percentage

   total = bill + tip + tax

   

   return total / people

Problem You Need to Solve for This Lab:

You are asked to write an app to keep track of a relatively small music library. The app should load song information from a data file once the app is started. It should allow user to view, add, remove, and search for songs. The app should save the data back to the same data file when the program exits.

What Your Program Should Do:

Write an interactive text based menu interface (using a loop) that will allow the user to

ï‚· Enter information for a new song

ï‚· Display information for all the songs in the database with index for each song

ï‚· Remove a song by index

ï‚· Search for songs by a certain artist

ï‚· Search for songs by a certain album

ï‚· Quit

For each song, you need to keep track of:

title

artist

duration

album

Allow the program to keep looping until user wants to quit. When the program starts, it should load the tasks from external file ("songs.txt") into memory. When user enters information about the new song, the program needs to read them in, save them in memory and eventually write them to the external data file ("songs.txt"). The file format could look like:

Stereo Hearts;Gym Class Heroes;3;34;The Papercut Chronicles II
Counting Stars;OneRepulic;4;17;Native
The ';' is used as a delimiter or field separator. Each record ends with a new line character.

Some Implementation Requirements:

Write at least four functions WITH arguments for this assignment.

Use struct named Song to model each song

Use array of structs to model the collection of songs.

Hint: In this assignment, some data fields may have multiple words in it. Therefore,

you now SHOULD read using the 3 argument version of get.

Watch out. When using the 3 argument version of get you need to make sure to

remove the delimiter or newline. Therefore, anytime you read (even a confirmation

message), make sure to eat the newline using cin.ignore(...)!

Make sure to have a delimiter written between each item in the file – like a newline.

This will be important when you read the information back from the file.

For submission, your data file should contain a sufficient set of test data. It should have test cases for same artist with multiple songs and same album with multiple songs in it.

Do-Not List:

No Global Variables (you can have global constants)

Do not use Classes or Linked Lists

You must use cstring and char arrays. (do not use )

No use of the stdio library (use iostream and fstream)

Instead of the string class, you will be using arrays of characters and the cstring library

No STL containers such as vector. You must implement your own array for this class.
