Do you think robots will take millions of jobs when they're put in different positions such as doctors or taxi drivers?
Yes, of course.
When you replace people with technologically advanced robots, it can disturb the economic factors. Although I don't agree with using robots as an every day, common thing, such as self-driving cars or like in the question, using robots as doctors. Technology is technology, it will always need updates and sometimes they break down or need repairs, so that could provide jobs for people; tech jobs that is. Not everybody is tech savvy though, but you learn. I still don't agree with it, but it is what it is.
Assuming that your company uses the Class A network 100.0.0.0/8, with what subnet mask would you need to configure all computers on the network to divide this network 11 times to match the comany's 11 departments?
Answer:
Class A network 100.0.0.0/8, we need to divide it so that it can use 11 department, therefore 2^{4} = 16 maximum subnet. The subnet mask 255.240.0.0/12. The hosts per subnet are 2^20 = 1048574. The first 5 subnet range is attached with this question.
Explanation:
The IP address is 32 bits, The default subnet of class A is 255.0.0.0/8, but in this case we take 4 bits from host and add it to network bits so 8+4 = 12, that's why mask bit is 12.
8 bits + 8 bits + 8 bits + 8 bits
100 . 0 . 0 . 0
we take 4 bits from 2nd octet so that it can use in 11 departments, so the remaining 4 bits + 8 bits + 8 bits = 20 bits
2^{20} = 1048574 hosts in each subnet
2^ {4} = 16 subnet ( 0 to 15 range)
when we subtract 255-15 = 240 so that the subnet mask is 255.240.0.0 / 12

how is hardware different from sofware?
Answer:
Computer hardware is any physical device used in or with your machine, whereas software is a collection of code installed onto your computer's hard drive. For example, the computer monitor you are using to read this text and the mouse you are using to navigate this web page are computer hardware.
All software utilizes at least one hardware device to operate. For example, a video game, which is software, uses the computer processor (CPU), memory (RAM), hard drive, and video card to run. Word processing software uses the computer processor, memory, and hard drive to create and save documents.
How are arrays stored in memory?
In Java, arrays are objects, therefore just like other objects arrays are stored in heap area. An array store primitive data types or reference (to derived data) types Just like objects the variable of the array holds the reference to the array.

Explanation:
The weakest link in the security of an IT infrastructure is the server.
A. True
B. False
Answer:
False
Explanation:
"The weakest link in the security of an IT infrastructure is not a server, it is a internet that is weakest link. Because connecting your device or computer to internet immediately exposes them to attack. Through intrusion detection system (IDS) we can examine IP data stream for common attack and malicious intent patterns."
Final answer:
The assertion that the server is the weakest link in IT security is false, as human factors often represent a greater risk. Security threats include local networks, viruses, and interconnected device vulnerabilities that could lead to cascade failures.
Explanation:
The statement 'The weakest link in the security of an IT infrastructure is the server' is False. While servers can be vulnerable, they are not inherently the weakest link in security. In fact, the weakest link is often due to human factors, such as social engineering or poor password practices. Comprehensive cybersecurity measures must cover a wide range of components including local networks, protection against viruses, and guarding against groups of compromised computers known as botnets.

how do computers benefit individuals' health care?
Answer:
By having personal health records available on a computer, more doctors have access to an individual's information. This allows doctors to view all prescriptions that a person is on, which can help protect patients from conflicting medications to be taken at once, and can save time if a patient doesn't have to redo tests and procedures because the doctor doesn't have the records.

Statistical hypothesis testing involves testing the --------------- hypothesis and then make a decision about the ___________ hypothesis.
Answer:
Explanation:
null hypothesis
alternative hypothesis
Answer:
Statistical analysts test a hypothesis by measuring and examining a random sample of the population being analyzed. All analysts use a random population sample to test two different hypotheses: the null hypothesis and the alternative hypothesis.
Explanation:
Write and test a Python program to find and print the largest number in a set of real (floating point) numbers. The program should first read a single positive integer number from the user, which will be how many numbers to read and search through. After reading in all of the numbers, the largest of the numbers input (not considering the count input) should be printed.

The process of representing data in digital form so it can be used by a digital computer is called decimal byterepresentation. - true or false
The process of turning data into digital form for use by a digital computer is called 'digitization', not 'decimal byte representation'.
Explanation:As asked here The statement the process of representing data in digital form so it can be used by a digital computer is called decimal byte representation - is false. The term is not 'decimal byte representation'. The correct term for this process is 'digitization'. Digitization is the process of converting information into a digital (i.e., computer-readable) format, where the information is organized into bits. These bits can then be used by digital devices and systems including computers.

Write a C++ program that prompt the user to enter three points (x1, y1), (x2, y2), (x3,y3) of a triangle and
Answer:
#include<iostream>
using namespace std;
int main(){
int x1,x2,x3;
int y1,y2,y3;
cout<<"Enter the value of first point(x1,y1): ";
cin>>x1>>y1;
cout<<"\nEnter the value of second point(x2,y2): ";
cin>>x2>>y2;
cout<<"\nEnter the value of third point(x3,y3): ";
cin>>x3>>y3;
}
Explanation:
first include the library iostream for use the input/output commands
then, write the main function. within the main function declare the variable which store the value of points.
after that, use the 'cout' for output. It has the function which print the value or message on the screen.
and 'cin' is used to store the value in the variable.
So, in the above code cout ask for enter the value of point and after enter value by user, cin store in the variables.
Note: you have to enter two value with space or by enter.
