Answer:
To get the range of very lines in a switch or a router, in the global mode, type " line very" and the question mark after the space. It displays the ranges of valid very lines in the device.
Explanation:
Routers and switches are intermediate components of a computer network. They are used to connect various nodes and networks. For a remote connection, they use the virtual interface called vty to connect to computers for management purposes. These vty lines allows for SSH and telnet access from workstations and the range of very lines are predetermined and limited and varies for all switches and routers.

#include <bits/stdc++.h>
using namespace std;

public:

int area(){

}
bool equals(Rectangle* r){
// They have the exact same length and width.
if (r->length == length && r->breadth == breadth)
return true;
// They have the same area
if (r->area() == area())
return true;
// They have the same perimeter
if (r->perimeter() == perimeter())
return true;
// They have the same shape-that is, they are similar.
if (r->length/length == r->breadth/breadth)
return true;

Rectangle *r_1 = new Rectangle(6,3);
Rectangle *r_2 = new Rectangle(3,6);

A network administrator notices that some newly installed Ethernet cabling is carrying corrupt and distorted data signals. The new cabling was installed in the ceiling close to fluorescent lights and electrical equipment
Two factors may interfere with the copper cabling and result in signal distortion and data corruption are :
EMI
RFI
Explanation:
- EMI (electromagnetic interference) is the disruption of operation of an electronic device when it is in the vicinity of an electromagnetic field (EM field) in the radio frequency (RF) spectrum that is caused by another electronic device.
- During EMC testing, radiated emissions measurements are made using a spectrum analyzer and or an EMI receiver and a suitable measuring antenna.
- EMI (Electromagnetic Interference) is also called RFI (Radio Frequency Interference).
- Conducted RFI is unwanted high frequencies that ride on the AC wave form. Radiated RFI is emitted through the air. There are many pieces of equipment that can generate RFI, variable frequency drives included.
- The internal circuits of personal computers generate EM fields in the RF range.
