A program is used to convert from minutes to seconds. Write the directive for defining the conversion factor called MINUTE_TO_SECOND_FACTOR as a constant that cannot be changed and define it as a string 60.
Answer:
I am writing a simple program in C++ However, let me know if you need this program to be implemented in some other programming language .
Program#include <iostream>
using namespace std;
#define MINUTE_TO_SECOND_FACTOR 60
int main()
{ int minutes;
cout<<"enter the time in minutes: ";
cin>>minutes;
int output;
output = minutes * MINUTE_TO_SECOND_FACTOR;
cout<<minutes<<" minutes = "<<output<<" seconds.";
Output:enter the time in minutes: 45
45 minutes = 2700 seconds
Explanation:I will explain every line of the code .
The first statement contains a pre-processor directive which is a library that contains input and output functions for a program.The next line namespace is used so that the computer can identify cout, cin and endl used in the program.This is a define directive #define MINUTE_TO_SECOND_FACTOR 60Here define directive is used for declaring a macro which is MINUTE_TO_SECOND_FACTOR. Here this macro is given a value 60. Now wherever in the program this macro is used, it will be replaced by 60. This macro MINUTE_TO_SECOND_FACTOR can be used as a constant and cannot be changed.Next line enters the body of the main function.variable minutes is declared which is used to store the value in minutes. variable is declared which will store the result of the conversion from minutes to seconds.output = minutes * MINUTE_TO_SECOND_FACTOR; statement works as follows:In this statement written above the value of minutes is multiplied by 60 ( value of the macro MINUTE_TO_SECOND_FACTOR) and the result of this multiplication is stored in the output variable.
As we know that 1 minute =60 secondsLet suppose the input number is 45 minutesThen output= 45 * 60
output= 2700 seconds.
Last statement displays the converted value of minutes into seconds which is stored in output variable.Which of the following kinds of computing refers to an environment of servers that house and provide access to resources users access through the Internet?

A switch that is configured to use the Spanning Tree Protocol will place a port in ____________ mode if sending traffic to it may cause a switching loop.
Answer:
Blocking Mode
Explanation:
Spanning Tree Protocol is used to allow path redundancy in the network without creating cycles/circles also called loops.
When two parts of the switched network are connected via two or more Layer 2 switches this result in a loop.
This affects the performance of the network as the result of broadcast packets flooding.
STP puts one port of the switch to forwarding mode and the rest of the ports within the same part of the network to the blocking mode to avoid broadcast packet flooding. STP puts all the ports that are allowing redundant paths to blocking mode and the one port that is left after this is placed in forward mode.
Spanning Tree Algorithm is used by STP to determine the optimal path of switch to the network.
Bridge Protocol Data Units are used to share the information about the optimal path determined by the spanning tree algorithm with other switches.
This information helps STP to eliminate the redundant paths.
So this is how STP allows only one active path to the destination while blocking all other paths to avoid switching loop.
Given a double variable named x that has been declared and given a value, let's use a binary search technique to assign an estimate of its square root to another double variable, root that has also been declared. Let's assume that x's value is greater than 1.0 -- that will simplify things a bit. Here's the general idea:
Since x>1, we know its square root must be between 1 and x itself. So declare two other variables of type double (a and b say) and initialize them to 1 and x respectively. So we know the square root must be between a and b. Our strategy is to change a and b and make them closer and closer to each other but alway make sure that the root we're looking for is between them. (Such a condition that must always hold is called an invariant.)
To do this we will have a loop that at each step finds the midpoint of a and b. It then squares this midpoint value and if the square of the midpoint is less than x we know that the root of x must be bigger than this midpoint: so we assign the midpoint to a (making a bigger and shrinking our a and b interval by half!)-- and we still can be sure that the root is between a and b. Of course if the midpoint's square is greater than x we do the opposite: we assign b the value of midpoint.
But when to stop the loop? In this exercise, just stop when the interval between a and b is less than 0.00001 and assign root the midpoint of a and b then.
We call this a binary search also because at each stage we cut the interval under consideration in half. Efficient as this method is, old Isaac Newton discovered an algorithm that is even more efficient and that's what the library function sqrt uses.
I have this:
double a=1, b=x;
double mid;
while(a-b>0.00001){
mid=(a+b)/2;
mid=mid*mid;
if (mid
a=mid;
else if(mid>x)
b=mid;
else
root=mid;
}
Answer:now
Explanation:
That’s tough

A(n) ____ instruction might look like a meaningless string of 0s and 1s, but it actually represents specific operations and storage locations.
a. COBOL languageb. programming languagec. ASCIId. machine language
Answer:
Option d is the correct answer.
Explanation:
Machine language is a language that is understood by any machine because it is made from the electric signal which has only two states on and off. On state refers to 1 and off-state refers to 1. The computer is also a type of machine so it can also understand machine language. The above question asked about the instruction which is made by 0's and 1's and it is used for the computers then the answer is Machine language which is described above and which is stated from the option d. Hence option d is the correct answer while the other is not because--
Option 'a' states about COBOL language which is an example of high-level-language, not the example of machine language.Option b states about the programming language which is a mixture of all language of computers.Option c states about ASCII which is not the correct answer.
The fundamental language of machines is machine code, often known as "machine language", and the further discussion can be defined as follows:
It is read by the operating system (CPU), is made up of digital binary integers, and seems to become a very long series of zeros and ones. If you have to deal with machine code, the command may seem to be a random string of zeros and ones, but it denotes precise operations and storage places.The wrong choice description can be defined as follows:
Its COBOL language is indeed an example of a high-level language, not a machine language.The programming language is a combination of all computer languages.ASCII is a character-to-code conversion code.Therefore, the final answer is "Option d".

A(n) _____ prevents a mobile device from being used until the user enters the correct passcode.
a. personal ID reader (PIDR)
b. lock screen
c. magnetic carriage
d. swipe card
Answer:
b. lock screen
Explanation:
Lock screen is a security feature provided by many mobile operating systems in mobile devices. This feature prevents unauthorized access to the device. This feature does not allow the mobile to be used unless the user performs a specific action rightly in order to get access of the mobile device. This action can be entering the correct password, pin-code, pattern. These days, the lock screen with new enhanced security features enables the users to unlock the mobile device using gestures like face recognition and also provides fingerprint lock feature that locks and unlocks the mobile device with the fingerprint of that device user. Its a good practice to set the lock screen in a way that it locks the device if it remains idle for specific time and the user is required to enter the password etc to unlock it. Lock screen is a beneficial feature when it comes to the security of the device and the data stored in it.What cloud services allows developers to create, test, and run solutions on a cloud platform without having to purchase the underlying hardware and software?

You recently set up a DHCP server and need to configure your computer to start using it. Click the IPv4 properties option that you would select to use the DHCP server to recieve IP configuration information.
Answer:
Dynamic IP address configuration.
Explanation:
In information technology, there are two ways of configuring IP address on a computer system, namely static and dynamic configuration.
In the computer system, the IP address is configured by selecting the static radio button and typing in the IP address, subnet mask and default IP address. The dynamic IP address configuration requires a selected radio button indicating DHCP configuration and a DHCP server.
The DHCP server holds a range of IP addresses that is used assign IP addresses automatically to a client system.
"Two technicians are discussing FWD driveshaft service. Technician A says that removal of the driveshaft usually requires partial disassembly of the front suspension. Technician B says that the first step in driveshaft removal is to loosen the front hub nut. Which technician is correct?
Answer:
Technician A only noisy in 1st
Explanation:
Final answer:
Technician B's statement about driveshaft removal is typically correct; the first step is to loosen the front hub nut. For a FWD vehicle, the friction at the front wheels that propels the car is in the direction of motion.
Explanation:
When servicing a front-wheel-drive (FWD) vehicle's driveshaft, the approach varies by make and model, but there are commonalities in the process. Technician A's assertion that driveshaft removal often necessitates partial disassembly of the front suspension may hold true since various suspension components can obstruct the removal of the driveshaft. The statement by Technician B that the first step in driveshaft removal is to loosen the front hub nut is typically correct, as the hub nut secures the driveshaft to the wheel hub and must be loosened while the vehicle's weight is still on the wheels to prevent rotation, prior to lifting the vehicle.
The question you've asked about friction on wheels of a front-wheel driven car is different from the discussion of driveshaft service. For a front-wheel-driven car, the friction at the front wheel is what propels the car forward, so the friction is in the direction of motion (option c). Consequently, the friction at the rear wheel tends to be less since it's mostly rolling resistance and does not provide driving force.
The fundamental difference between a switch and a router is that a switch belongs only to its local network and a router belongs to two or more local networks.True/false
Answer:
The statement is True
Explanation:
Switches or routers help to connect computers together. The most basic explanation to this is that switches connect computers within a particular network, while routers connect multiple networks together. Switches are mostly used in areas where there are large networks. In most cases, large networks consist of various switches and in order for individuals to access the internet, these switches are connected to one router.
Which is an example of line-of-sight Internet service?
Cable
DSL
Fiber
WiMax
The answer is WiMAX.
Wimax is a wireless, data communication technology. It means, Worldwide Interoperability for Microwave Access. It is considered as line of sight service provider because it can transmit data between distant devices and using stronger connections. Since it supports stronger signal, it is considered as line of sight provider. It can transfer up to 66GHz amount of frequency or signal rate.
The correct example of line-of-sight Internet service is WiMax. Line-of-sight means the transmitting and receiving points must directly see each other without obstructions.
The correct Option is WiMax. Line-of-sight Internet service refers to a type of connection where the transmitting and receiving antennas must be directly visible to each other with no obstruction in between.
WiMax (Worldwide Interoperability for Microwave Access) is a wireless communication standard designed to provide high-speed Internet access over long distances and typically relies on line-of-sight transmission for optimal performance, especially in rural areas where traditional broadband options like DSL, cable, or fiber-optic may not be available.
