Because the bot is also a malware the infects the whole computer system and host's network by the hackers, using the remote control by which they remotely controlled the user's system without the permission of the user for the purpose of stealing the confidential data and the information from the computer system of the user they aimed.
Describing where this quadratic is negative involves describing a set of numbers that are simultaneously greater than the smaller root (+1) and less than the larger root (+3). Write a C++ Boolean expression that is true when the value of this quadratic is negative.
Answer:
The Boolean Expression is (x >1)&&(x<3)
Explanation:
As mentioned in the question that to describe where the given quadratic is negative involves describing:
a set of numbers that are greater than the smaller root which is +1a set of numbers that are less than larger root which is +3So when the quadratic is negative the following boolean expression is true:
(x >1)&&(x<3)
This expression means that the set of numbers are greater than 1 and less than 3. x represents such number. So this boolean expression returns a boolean value true when the 1 and 2 are true. It can also be returned as 1 (which means true in boolean). In the above expression > and < are relational operators used for comparison and & is called logical operator which depicts that both (x>1) and (x<3) should hold or should be true for the expression to return true.
Example of boolean expression
The logic of Boolean expressions is explained with the following chunk of C++ code. For example x is a number, (x>1)&&(x<3) is an expression whose result is stored in "bool" data type variable result. If this expression holds true(i.e. value of x is greater than 1 and less than 3) then output will be 1 (true) otherwise 0(which means false).
int x;
cout<<"enter value";
cin>>x;
bool result;
result=(x>1)&&(x<3);
cout<<result;
Olivia manages wireless security in her company and wants completely different WiFi access (ie different SSID, different security levels, different authentication methods) in different parts of the company. What’s the best choice for Olivia to select in WAPs?
Answer:
The right answer is FAT WAP.
Explanation:
There are mostly two types of WAPs.
Fat WAP: Fat WAPs can be defined as an access point that can not be configured by switches. if the user uses multiple Fat AP then each Fat AP has to configured individually which means that it can give different SSID or passwords. Thin WAP: Thin WAPs can be defined as an access point which can be configured according to switch. which means Thin AP gives the same configuration while using multiple numbers.Hence according to the scenario, the most appropriate answer is FAT WAPs because it can be configured as a different WIFI set up in different parts of a company.
Some systems provide a small amount of dedicated memory built into the CPU that maintains a record of previous choices for each of several branch instructions that have been used in the program being executed to aid in determining whether a branch is likely to be taken. What are the contents of this memory called.
Answer:
Option (B) i.e., branch history table is the correct answer to the following question.
Explanation:
In the above question, some part is missing i.e., options which are:
a) look-ahead table
b) branch history table
c) branch prediction table
d) future speculation table
Because the branch history table maintains the records of the previous data or information and instructions also that are used after when it needed in the program or any other fields and it is the table of the shift register. So that's why the following option is correct. it also used design to store the previous data in the shift register.
Test if a number grade is an A (greater than or equal to 90). If so, print "Great!". Sample Run Enter a Number: 98 Sample Output Great! Hint Grades may be decimals
Answer:
Using Python language :
a = eval ( input ( "Enter a mark please"))
if ( a <0){
print ("Invalid mark")};
else if (a >=90 && a <=100){ print
( "GREAT")};
Explanation:
The question is about writing a program to check if a number grade is an A by validating the score range and then categorizing it according to a grading scale. The program would likely involve conditional statements to compare the entered score against defined grade thresholds.
To test if a number grade corresponds to an A, a program must first verify that the entered score is within an acceptable range. For a score to be considered an A, it must be greater than or equal to 90 or within a specified range that correlates to an A in a given grading schema. In Python, such a program could look like this:
score = float(input("Enter a score between 0.0 and 1.0: "))The standard rules for rounding can also be applied accordingly within the program to ensure that grades like 89.5 are rounded to 90, hence considered an A.

Josh, as an administrator for a health care company, is required to support an older, legacy application. He’s concerned about the application having some vulnerabilities that would affect the remainder of the network. Of the following, which option is the most efficient way to mitigate this?A) Use an application containerB) Implement SDNC) Run the application on a separate VLAND) Insist on an updated version of the application
Answer:
Use an application container.
Explanation:
Host operating system is software installed in a computer that interacts virtually with a server and also describes the difference between its software and a guest operating system.
It interacts with the hardware and works with atype 2 hypervisor which does not interact with the hardware but create virtual machine interfaces for multiple guest operating system to be installed, which are not necessarily the same as the host os.
Host os can also be used to describe operating systems that make use of container based virtualization. Containers are storage partitions used to hold applications separately on the same server, instead of replicating the operating system.
So with a container, Josh can separate the legacy application from other applications in the server.
Pressing ____ in the middle of a numbered list creates a new numbered paragraph and automatically renumbers the remainder of the list.
a.[Enter]
b.[Ctrl]
c.[Esc]
d.[Alt]
Answer:
Option a is the correct answer.
Explanation:
In an MS-WORD Document, when the user wants to write some line with the help of bullets or numbers then he needs to press enter when he had completed the first line and wants to proceed for the second line.
The question scenario also suggests the same which is described above. Hence Enter will fill the blank of the question statement. Hence Option 'a' is the correct answer while the other is not because--
Option b suggests about 'control' key, which is used to select or copy or cut if any other key is pressed with it.Option c suggests about 'ESC' key, which is an escape key used to escape some process.Option d suggest 'ALT' key, which is not used in MS-WORD Document for any purpose.Assume the list numbers1 has 100 elements, and numbers2 is an empty list. Write code that copies the values in numbers1 to numbers2.
Answer:
numbers1 = [5]*100
numbers2 = numbers1[:]
print(numbers2)
Explanation:
We have used the Python programming language to solve this problem. First we created a list to have 100 elements line 1, numbers1 = [5]*100, This statement creates a list that has 100 elements (the integer 5). In line two, we assign the elements in the the first list to the second list numbers2, notice the full colon in the statement numbers2 = numbers1[:], This allows the elements of the first list to be copied into the second list and on line 3, we printout the the second list.
Final answer:
To copy values from one list to another in Python, you can use a for loop or a list comprehension, both methods will provide a separate copy of the original list.
Explanation:
To copy the values from numbers1 to numbers2 in Python, you can use a for loop or a list comprehension. Below are two examples of how this can be accomplished:
Using a for loop:numbers2 = []Both methods will create a separate list, numbers2, with the same values as numbers1, ensuring that the original list is not modified.
A security analyst is checking the bash command history on a Linux host that was involved in a data breach. The data breach stemmed from the Linux host running a series of commands against a web server on the internal network, which exploited a vulnerability in an unpatched, outdated Apache module.Given this scenario, which of the following commands might the analyst find in the bash command history for banner grabbing? (Select TWO).A. arpB. tracertC. nmapD. telnetE. nslookup
Answer:
C. nmap & D. telnet
Explanation:
Why nmap?
nmap is a command that is used to determine which hosts are running and which services are being executed in such hosts. This is a well-known command among the hacking community to provide access to this type of information in order to grab information from open ports.
Why telnet?
Like nmap, telnet is used to examine which ports are opened and which ones are closed. Opened ports represent a breach in the network, leading to hackers accesing the information through this access point.
how to engage more underrepresented and under resourced students in stem programs?
Answer:
Through after school programs
Explanation:
Under represented and under resourced students can be better engaged in STEM programs through the establishment of after school state of the arts learning centres that can augment for the vacuum in the regular school system.
In such programs, the use of technological platforms with an integrated electronic learning system is necessary, because it avails the students the opportunity to brace up with the evolving impact of information technology to learning and personal developments.
Secondly, the use of immediate resources within the reach of these under privileged and under resourced students is a necessity. for example, a student in a rural community could start become more engage in engineering designs, building technology, instrumentation and architecture through the use of disposed cartons used to construct buildings, cars etc.

Canada and the U.S. both produce wheat and computer software. Canada is said to have the comparative advantage in producing wheat if: a. Canada requires fewer resources than the U.S. to produce a bushel of wheat. b. the opportunity cost of producing a bushel of wheat is lower for Canada than it is for the U.S. c. the opportunity cost of producing a bushel of wheat is lower for the U.S. than it is for Canada. d. the U.S. has an absolute advantage over Canada in producing computer software
Answer:
The answer is B.
Explanation:
In terms of economics, there is "Absolute Advantage" and "Comparative Advantage".
Absolute Advantage is used when someone is the best at a certain task than someone else, they have the absolute advantage.
Comparative Advantage does not work quite the same, you don't have to be the best at something, if you can produce the same product or results at a lower cost, you have comparative advantage.
And in the option B, it says that Canada is said to have comparative advantage if the opportunity cost is lower for Canada than it is for the US. Opportunity cost is the amount that it costs for someone to produce something and if you have lower opportunity cost, you can have the comparative advantage without having a higher production rate.

A network design engineer has been asked to design the IP addressing scheme for a customer network. The network will use IP addresses from the 192.168.30.0/24 network. The engineer allocates 254 IP addresses for the hosts on the network but excludes 192.168.30.0/24 and 192.168.30.255/24 IP addresses. Why must the engineer exclude these two IP addresses?
Answer:
192.168.30.0/24 is the network IP address and 192.168.30.255/24 is the IP broadcast address.
Explanation:
The first IP (192.168.30.0/24) address of your subnet is the network address, the last IP (192.168.30.255/24) address of your subnet is your broadcast address and the available usable IP addresses in your subnet are subnet size -2, because network address and broadcast address cannot be allocated to a system.
The engineer must exclude 192.168.30.0 as it is the network address and 192.168.30.255 as it is the broadcast address, both of which are critical for network management and cannot be assigned to individual hosts.
An IP (Internet Protocol) address is a unique code used to identify devices on a network. The network the engineer is working on uses the 192.168.30.0/24 subnet, which corresponds to a block of 256 IP addresses ranging from 192.168.30.0 to 192.168.30.255.
However, within each subnet, two specific addresses are reserved and cannot be assigned to hosts:
192.168.30.0 is the 'network address' that identifies the subnet itself. It is used by routers and other networking equipment to determine the routing of packets.192.168.30.255 is the 'broadcast address' used for communication with all devices on the subnet simultaneously. Messages sent to this address are received by all devices in the subnet.These reserved addresses ensure effective network management and communication, preventing conflicts and ensuring that all devices can communicate efficiently.
In the Windows command-line syntax, a directory is referred to by which character(s)?
Answer:
'\' is the correct answer for the above question.
Explanation:
In the windows command line '\' symbol is used for the directory. In any computer system, the hard disk is a large set of memory. so the user needs to partition to make one or more part and that part is known as a drive.
The drive is the most important part of the system so it is uniquely identified on the command line by the help of '\' symbol.
Just for example if a user wants to open the D drive in a window command line by pressing D: then the command line shows--
D:\>
Hence '\' is used to refer the directory in the windows command line. Hence the answer is '\'.

Planning : this is the feasibility study of the needs the application is meant to solve.Analysis: in this stage, the client prior problems and best solution are written down.Design: this stage gives a graphical design of the application with focus on the problems it is meant to solve. Prototyping and wireframing technologies are used.Development: In this stage, lines of code are written, debugged, tested and continually reviewed.The other stages are deployment and maintenance.
Final answer:
A design review in software development is best conducted during the development of functional and design specifications to ensure alignment with project requirements and constraints, allowing for necessary refinements.
Explanation:
A design review in the software development process should be conducted as the functional and design specifications are being developed based on the requirements. It is crucial to ensure that the design aligns with the project requirements and constraints before moving forward. Testing and evaluation may reveal weaknesses or areas for improvement in the design, prompting refinements to better meet the criteria.

Choose the type of attack that is based on entering fake information into a target network domain name server?
Answer:
DNS poisoning
Explanation:
DNS is a server service that verifies or resolves an IP address to a site or domain name. It's services is made available with a dhcp request from a client system, providing the ip address of the DNS server. The DNS server has the records of domain name linked to their individual ip addresses.
When an attacker wants a client to visit his site without knowing the site is not genuine, he gains access to the dns server and changes the information or poisons the entries of the server. So if the client tries to access that site, it takes him to the attackers site. This is called DNS poisoning.

With 2020 Kicks’ Easy-Fill Tire Alert, what happens when the correct pressure is reached during inflation?
Answer:
THE HORN SOUNDS when the correct pressure is reached during inflation with 2020 kicks' Easy-Fill Tire Alert
Explanation:
Properly inflated tires are able to save up to 11 cents per gallon on gas and extend a tire’s life by over 4,000 miles, but it’s hard to know when the tires are at the proper pressure. Luckily, Nissan’s Easy-Fill Tire Alert system will take away the guesswork and help fill tires to the correct pressure every time—without needing a handheld pressure device!
First, park your vehicle and apply the parking brake.
Leave the ignition on (accessory mode) but keep the engine off
As you start to fill a tire, the exterior lights will flash to indicate that the system is monitoring the change in pressure
Once the tire meets the correct pressure, the horn will go off to tell you it’s done
If the tire is over-inflated, the horn will sound again, and the hazard lights will flash 3 times to tell you that you need to release some air

Practice problems on functions. Write C function(s) to carry out the specified tasks. For each problem, also write the suggested application program(s) that apply the function. (1) Write a function multiPrint(int n, char c) that prints n copies of a character c.
Answer:
Function:
int fun(int n,char c) // function definition with a two argument in which variable n is a integer type and variable c is a character type.
{
while(n>0)// while loop
{
printf("%c",c); // print statement for character
n--; // decrease statement to false the loop.
}
return 0; //return statement.
}
output:
When the user pass n=5 and c='a', it will prints 5 times 'a' character.When the user passes n=10 and c='t', it will print 10 times 't' character.Explanation:
Firstly we declare a function of two arguments in which variable n is an integer type and variable c is a character type. Then in the function body, we use while loop from n times iteration because question demands to print n time any character.Then in the loop body, we use a print statement to print a character and a decrease statement to false the loop after a finite iteration.
