Answer:

WPAN ( wireless personal area network )

Explanation:

a. PAN ( personal area network )

This network is limited to the work place of a single person. Hence, the name given as personal area network. The devices connected by PAN belong to the range supported by the technology used to implemented the personal area network.

The devices present in this type of work place are connected to each other through PAN. PAN can connect computer, mobile and other technological devices which support PAN.

The data is transferred among these devices through PAN.

Both wireless and wired networks can be used to implement PAN. Wired PAN is achieved by using USB. Wireless PAN uses various technologies which are discussed below.

b. WPAN ( wireless personal area network )

The wireless PAN covers only short distance and hence requires low power.

The distance can range from few centimetres to few meters.

IEEE 802 has described the technologies and standards for each type of network. This network is implemented mainly by technologies such as Bluetooth, wireless USB, IrDA.

1. Bluetooth uses radio waves of short waves. Devices like keyboard, mobile phones, personal digital assistant ( PDA ) use this technology to communicate.

WPAN implemented using Bluetooth is known as piconet. It can connect up to 8 devices. Among them, one is the master device while rest devices become the slaves.

The range of such a network varies from 10 meters to 100 meters.

2. IrDA stands for Infrared Data Association. This technology uses infrared light. Examples using this technology include printers and scanners.

Plugging in

i. Devices supporting WPAN can only communicate with each other when they are within the supported range or distance from each other.

ii. In addition, these devices should have the capability to block devices which will cause unnecessary interference or are not authorized to gain information.

How can an exception be explicitly raised in C++? How are exceptions bound to handlers in C++?
xenn [34]

Answer:

Exceptions are raised using throw statement in c++.

Explanation:

Try block is used to keep the statements which we felt that they will raise an exception. Catch block is used to catch the exception which is thrown by the try block.

#include<iostream.h>

void main(){

int x,y,z;

try{

cout<"enter 2 numbers";

cin>>x>>y;

if(y==0)

throw y;

z=x/y;

}

catch(int x){

cout<<"exception caught";

}

}

Design and implement an algorithm that gets as input a list of k integer values N1, N2,..., Nk as well as a special value SUM. Y
satela [25.4K]

Answer:

Follows are the code to this question:

def FindPair(Values,SUM):#defining a method FindPair  

   found=False;#defining a boolean variable found

   for i in Values:#defining loop for check Value  

       for j in Values:#defining loop for check Value

           if (i+j ==SUM):#defining if block that check i+j=sum

               found=True;#assign value True in boolean variable

               x=i;#defining a variable x that holds i value

               y=j;#defining a variable x that holds j value

               break;#use break keyword

       if(found==True):#defining if block that checks found equal to True

           print("(",x,",",y,")");#print value

       else:#defining else block

           print("Sorry there is no such pair of values.");#print message

Values=[3,8,13,2,17,18,10];#defining a list and assign Values

SUM=20;#defining SUM variable

FindPair(Values,SUM);#calling a method FindPair

Output:

please find the attachment:

Explanation:

In the above python code a method, "FindPair" is defined, which accepts a "list and SUM" variable in its parameter, inside the method "found" a boolean variable is defined, that holds a value "false".

  • Inside the method, two for loop is defined, that holds list element value, and in if block, it checks its added value is equal to the SUM. If the condition is true, it changes the boolean variable value and defines the "x,y" variable, that holds its value.
  • In the next if the block, it checks the boolean variable value, if the condition is true, it will print the "x,y" value, otherwise, it will print a message.
