Answer and Explanation:
public class Main {
int Carmodel;
int Purchaseprice;
int Currentyear;
Public void setPurchasePrice(int Purchaseprice){
this.Purchaseprice=Purchaseprice;
}
Public void getPurchasePrice(){
return Purchaseprice;
}
static void printInfo(int Carmodel int Currentyear ){
this.Carmodel=Carmodel;
this.Currentyear=Currentyear;
System.out.println(getPurchasePrice() Carmodel Currentyear);
}
}
The above java program defines a class that has three methods, a get method that returns purchase price of the object, a set method that sets purchase price of the object, and a print method that print out the information about the car object(model, year, price). The print method also takes arguments and assigns values of the arguments/parameters to the object, then prints all.
The importance of the 8 functions of an operating system
Answer:
Explanation:
Important functions of an operating System:
Security –
The operating system uses password protection to protect user data and similar other techniques. it also prevents unauthorized access to programs and user data.
Control over system performance –
Monitors overall system health to help improve performance. records the response time between service requests and system response to have a complete view of the system health. This can help improve performance by providing important information needed to troubleshoot problems.
Job accounting –
Operating system Keeps track of time and resources used by various tasks and users, this information can be used to track resource usage for a particular user or group of user.
Error detecting aids –
Operating system constantly monitors the system to detect errors and avoid the malfunctioning of computer system.
Coordination between other software and users –
Operating systems also coordinate and assign interpreters, compilers, assemblers and other software to the various users of the computer systems.
Memory Management –
The operating system manages the Primary Memory or Main Memory. Main memory is made up of a large array of bytes or words where each byte or word is assigned a certain address. Main memory is a fast storage and it can be accessed directly by the CPU. For a program to be executed, it should be first loaded in the main memory. An Operating System performs the following activities for memory management:
It keeps tracks of primary memory, i.e., which bytes of memory are used by which user program. The memory addresses that have already been allocated and the memory addresses of the memory that has not yet been used. In multi programming, the OS decides the order in which process are granted access to memory, and for how long. It Allocates the memory to a process when the process requests it and deallocates the memory when the process has terminated or is performing an I/O operation.
Processor Management –
In a multi programming environment, the OS decides the order in which processes have access to the processor, and how much processing time each process has. This function of OS is called process scheduling. An Operating System performs the following activities for processor management.
Keeps tracks of the status of processes. The program which perform this task is known as traffic controller. Allocates the CPU that is processor to a process. De-allocates processor when a process is no more required.
Device Management –
An OS manages device communication via their respective drivers. It performs the following activities for device management. Keeps tracks of all devices connected to system. designates a program responsible for every device known as the Input/Output controller. Decides which process gets access to a certain device and for how long. Allocates devices in an effective and efficient way. Deallocates devices when they are no longer required.
File Management –
A file system is organized into directories for efficient or easy navigation and usage. These directories may contain other directories and other files. An Operating System carries out the following file management activities. It keeps track of where information is stored, user access settings and status of every file and more… These facilities are collectively known as the file system.
A(n) _____ is a network connection device that can build tables that identify addresses on each network.
Answer:
Dynamic Router
Explanation:
A dynamic router is a network connection device that can build tables that identify addresses on each network.
What is Dynamic network?Dynamic networks are networks that vary over time; their vertices are often not binary and instead represent a probability for having a link between two nodes.
Statistical approaches or computer simulations are often necessary to explore how such networks evolve, adapt or respond to external intervention.
DNA statistical tools are generally optimized for large-scale networks and admit the analysis of multiple networks simultaneously in which, there are multiple types of nodes (multi-node) and multiple types of links (multi-plex).
Therefore, A dynamic router is a network connection device that can build tables that identify addresses on each network.

It is common for people to name directories as dir1, dir2, and so on. When there are ten or more directories, the operating system displays them in dictionary order, as dir1, dir10, dir11, dir12, dir2, dir3, and so on. That is irritating, and it is easy to fix. Provide a comparator that compares strings that end in digit sequences in a way that makes sense to a human. First compare the part before the digit as strings, and then compare the numeric values of the digits.

Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a comma, including the last one.Ex: If the input is:5 2 4 6 8 10the output is:10,8,6,4,2,To achieve the above, first read the integers into a vector. Then output the vector in reverse.
Answer:
The program in C++ is as follows:
#include <iostream>
#include <vector>
using namespace std;
int main(){
vector<int> intVect;
int n;
cin>>n;
int intInp;
for (int i = 0; i < n; i++) {
cin >> intInp;
intVect.push_back(intInp); }
for (int i = n-1; i >=0; i--) { cout << intVect[i] << " "; }
return 0;
}
Explanation:
This declares the vector
vector<int> intVect;
This declares n as integer; which represents the number of inputs
int n;
This gets input for n
cin>>n;
This declares intInp as integer; it is used to get input to the vector
int intInp;
This iterates from 0 to n-1
for (int i = 0; i < n; i++) {
This gets each input
cin >> intInp;
This passes the input to the vector
intVect.push_back(intInp); }
This iterates from n - 1 to 0; i.e. in reverse and printe the vector elements in reverse
for (int i = n-1; i >=0; i--) { cout << intVect[i] << " "; }

B. installApplication(‘A’, 1);
Explanation:
Given
The above code segment
Required
The correct call to installApplication
The function installApplication is declared as void, meaning that it is not expected to return anything.
Also, it receives a character and an integer argument.
So, the call to this function must include a character and an integer argument, in that order.
Option D is incorrect because both arguments are integer
Option C is incorrect because it passes no argument to the function.
Option A is incorrect because it receives an integer value from the function (and the function is not meant not to have a return value).
Option B is correct
