Answer:

The digits 1 and 0 used in binary reflect the on and off states of a transistor. ... Each instruction is translated into machine code - simple binary codes that activate the CPU . Programmers write computer code and this is converted by a translator into binary instructions that the processor can execute .

Create a program in c/c++ which accepts user input of a decimal number in the range of 1 -100. Each binary bit of this number wi

kirill115 [55]

Answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

void switch_fun(int input)

{

//array to store binary of input number

int bin[7];

// convert the number into binary

for(int i=0; input>0; i++)

{

bin[i]=input%2;

input= input/2;

}

// print the switch number and their status

cout<<"Switch number:\t 1\t 2\t 3\t 4\t 5\t 6\t 7 \n";

cout<<"status: ";

for(int j=6;j>=0;j--)

{

// if bit is 1 print "ON" else print "OFF"

if(bin[j]==1)

cout<<"\t ON";

else

cout<<"\t OFF";

}

int main()

{

int n;

cout<<"enter the number between 1-100 only:");

// read a number in decimal

cin>>n

// validate the input

while(n<1 ||n>100)

{

cout<<"wrong input!! Input must be in between 1-100:"<<endl;

cout<<"enter the number again :";

cin>>n;

}

// call the function with input parameter

switch_fun(n);

return 0;

}

Explanation:

Read a decimal number from user. If the number is not between 1 to 100 the it will again ask user to enter the number until the input is in between 1-100.Then it will call the fun() with parameter n. First it will convert the decimal to binary array of size 7.Then print the status of switch.If bit is 1 then print "ON" else it will print "OFF".

Output:

enter the number between 1-100 only:-5

wrong input!! Input must be in between 1-100:

enter the number again :125

wrong input!! Input must be in between 1-100:

enter the number again :45

Switch number: 1 2 3 4 5 6 7

Status: OFF ON OFF ON ON OFF ON

RoseWind [281]

Explanation:

This is easily solvable with a for loop. Something like:

(I assume c++)

#include <iostream>

#include <string>

int main() {

take_input: //tag

std::string input;

cin >> input; //take the input

int spaceCount = 0;

char checking;

for(unsigned int i = 0; i == input.length(); ++i) {

checking = spaceCount[i];

if(checking == ' ')

spaceCount++;

}

if(spaceCount >= 1 && input.length >= 5)

std::cout << "Your name is " + input;

else

goto take_input; // reasks for input if the conditions are not met

return 0;

};

**remove all spaces before using the code, the if statements are messed up

The U.S. National Institute of Standards and Technology defines the incident response life cycle as having four main processes:

GuDViN [60]

Answer:

C. Post-incident activity.

Explanation:

An incident is a event of intrusion or attack or violation of an attempt of an attack. An incident response is an opposing response to an attack or violation.

An incident response life cycle are stages followed to mitigate a current attack or violation. The stages of the incident response life cycle are, preparation, detection and analysis, containing and eradicating and recovery, and post incident activity.

2. A host computer with an IP address of 172.16.29.155 using a subnet mask of 255.255.255.0 and a gateway of 172.16.29.1 pings a

ASHA 777 [7]

Answer:

From the host IP address and subnet mask, you can tell that both computers are on the same network. Host 172.16.29.155 will need to send an ARP request broadcast for 172.16.29.83 to get the MAC address and update its ARP table if the host 172.16.29.83 has not already done so.

Explanation:

<h2>ADDRESS RESOLUTION PROTOCOL (ARP)</h2>

Address Resolution Protocol (ARP) is a procedure for mapping a logical address known as the IP address to a physical address known as MAC (Media Access Control) address in a local area network. The job of the ARP is essentially to translate 32-bit addresses to 48-bit addresses and vice-versa when using IP Version 4 (IPv4) to communicate on the network.

Most of the computer programs/applications use logical address (IP address) to send/receive messages, however, the actual communication happens over the physical address (MAC address) this happens in the layer 2 of the OSI model. An ARP request is a broadcast, and an ARP response is a Unicast.

Scenarios when ARP is used:

Scenario-1: The sender is a host and wants to send a packet to another host on the same network.

· Use ARP to find another host’s physical address

Scenario -2: The sender is a host and wants to send a packet to another host on another network.

· Sender looks at its routing table.

· Find the IP address of the next-hop (router) for this destination.

· Use ARP to find the router’s physical address

Scenario -3: the sender is a router and received a datagram destined for a host on another network.

· Router checks its routing table.

· Find the IP address of the next router.

· Use ARP to find the next router’s physical address.

Scenario -4: The sender is a router that has received a datagram destined for a host in the same network.

· Use ARP to find this host’s physical address.

The situation in the question above falls under scenario-1. From the host IP address and subnet mask, you can tell that both computers are on the same network. Host 172.16.29.155 will need to send an ARP request broadcast for 172.16.29.83 so to get the MAC address and update its ARP table if the host 172.16.29.83 has not already done so.
