Effectus [21]3 years ago
6 0

Answer:

When data is written to a WORM drive, physical marks are made on the media surface by a low-powered laser and since these marks are permanent, they cannot be erased. Rewritable, or erasable, optical disk drives followed, providing the same high capacities as those provided by WORM or CD-ROM devices.

A painting company has determined that for every 115 square feet or wall space, one gallon of paint and eight hours of labor wil
Kay [80]

The program to calculate the total paint cost and other values is given below.

#include <iostream>

using namespace std;

int main() {  

 int rooms, laborChrg = 18;

 float paintChrg;

 float feetPerRoom[rooms];  

 float paintReq, laborHrs, paintCost, laborCost, totalCost, totalsqft=0;  

 cout<<"Enter the number of rooms to be painted "<<endl;

 cin>>rooms;  

 for(int i=0; i <= rooms; i++)

 {

 cout<<"Enter the square feet in room "<<endl;

 cin>>feetPerRoom[i];  

 // shortcut operator which is equivalent to totalsqft = totalsqft +     feetPerRoom[i];

 totalsqft += feetPerRoom[i];

 }  

 cout<<"Enter the cost of the paint per gallon "<<endl;

 cin>>paintChrg;  

 laborHrs = (totalsqft/115)*8;

 laborCost = laborHrs * laborChrg;  

 paintReq = totalsqft/115;

 paintCost = paintReq * paintChrg;  

 totalCost = laborCost + paintCost;  

 cout<<"The number of gallons of paint required "<<paintReq<<endl;

 cout<<"The hours of labor required "<<laborHrs<<endl;

 cout<<"The cost of the paint is "<<paintCost<<endl;

 cout<<"The labor charges are "<<laborHrs<<endl;

 cout<<"The Total cost of the paint job is "<<totalCost<<endl;  

 return 0;

}

Explanation:

The header files for input and output are imported.

#include <iostream>

using namespace std;

All the variables are taken as float except labour charge per hour and number of rooms.

The user is asked to input the number of rooms to be painted. An array holds the square feet in each room to be painted.

cout<<"Enter the number of rooms to be painted "<<endl;

cin>>rooms;  

for(int i=0; i <= rooms; i++)

{

cout<<"Enter the square feet in room "<<endl;

cin>>feetPerRoom[i];  

totalsqft += feetPerRoom[i];

}  

The above code asks for square feet in each room and calculates the total square feet to be painted simultaneously.

All the data to be displayed is calculated based on the values of labor charge per hour and gallons of paint needed, given in the question.

laborHrs = (totalsqft/115)*8;

laborCost = laborHrs * laborChrg;

paintReq = totalsqft/115;

paintCost = paintReq * paintChrg;

totalCost = laborCost + paintCost;

All the calculated values are displayed in the mentioned order.

Scale-based classification for networks allows us to differentiate PANs, LANs, MANs, and WANs. Moreover, the structure of a netw
Nana76 [90]

Answer:

1. PANs uses Star Topology.

2. LAN uses four topology (Bus, Ring, Star and Tree).

3. MAN uses Star Topology.

4. WAN uses Bus topology.

Explanation:

1. PAN is the personnel area network, in which different personnel devices of a person are connect to each other with the help of the central computer with the help of Bluetooth, WiFi or some other medium. The central computer will work like a hub and all the devices are directly connected to the central PC. It is same as the ring topology where all the devices are connected to the central PC. So we can say that, PANs use star topology.

2. LAN is the local area network that has been established with in the premises of the organization. In this type of network, four typologies involve to complete the network connection. First is star topology, that is used to connect all the devices with the switches. Then Bus topology is used to connect all the switches with the single main cable. Ring topology is involved to connect all the switches with each other. Tree topology is used to connect different block if the organization in the form of branch to connect the central router or switch.

3. MAN is the Metropolitan Area Network which is comprise of different LANs. All the LANs are connected to the Router in the form of Star topology.

4. WAN is the wide area network. In WAN different MANs are connected to the network through single cable. This type of network uses Bus topology.
