Assume there is a machine with the IP address 129.82.102.63 with netmask /23, and with a parent NW whose netmask is 255.255.224.

blagie [28]

Complete question is:

Assume there is a machine with the IP address 129.82.102.63 with netmask /23, and with a parent NW whose netmask is 255.255.224.0.

For each answer, do not include any spaces, give full IP addresses/netmasks where these are requested, give the "/" as part of the answer for slash notation.

a. What is the parent NW's netmask in dotted decimal notation?

b. What is the parent NW's netmask in slash notation?

c. What is the child NW's (subnet's) netmask in dotted decimal notation?

d. What is the child NW's (subnet's) netmask in slash notation?

e. How many bits are there for host # portion for the parent NW? (Another way to say the same thing is How many bits do we manage - on the parent NW?)

f. How many bits are there for NW# portion (within the parent address space) for the subnet?

g. How many bits are there for host # portion for the subnet?

h. How many addresses can we assign to machines/interfaces on this subnet?

Answer:

a. 255.255.224.0

b. /19

255.255 amounts to 16 bits being 1. .224 means 3 more bits are 1. So, in total 19 bits are 1. Hence, total network bits are 16 + 3 = 19.

c. 255.255.254.0

/23 means 8 + 8 + 7 that means

first 2 octets are 1s and 7 bits out of the 3rd octet are 1s. Hence, /23 means 255.255.254.0

d. /23

e. 13 bits are reserved for hosts

Parent network mask is /19, so total 32-19 = 13 bits

f. 19 bits are reserved for the network in the parent address.

g. 9 bits

Subnetwork's mask is /23, so total 32-23 = 9 bits for the host portion.

h. Since 9 bits are reserved for hosts, a total of 29 -2 = 510 machines can be assigned the IP addresses. Two addresses will be network and broadcast addresses for the subnet that can't be allocated to any device.

A half-life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half-lif

Ivan

Answer:

// program in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main() {

// variable

float n;

cout<<"Enter the initial value:";

//Read the input from the user

cin>>n;

//Declare variables for storing values at 6, 12 and 18 hours

float hours_6, hours_12, hours_18;

//Set precision level of floating point number

cout << fixed;

cout << setprecision(6);

//calculate values at 6, 12 and 18 hours

hours_6 = n / 2.0;

hours_12 = hours_6 / 2.0;

hours_18 = hours_12 / 2.0;

//display the output

cout<<"After 6 hours: "<<hours_6<<"mg"<<endl;

cout<<"After 12 hours: "<<hours_12<<"mg"<<endl;

cout<<"After 18 hours: "<<hours_18<<" mg"<<endl;

return 0;

}

Explanation:

Read an input from the user. Set the precision to 6 for displaying the result up to 6 decimal places. The first half life at 6 hours can be calculated by dividing the input by 2. The half life at 12 hours can be found out by dividing the half life value at 6 hours by 2. Similarly at 18 hours, we find the half life value by dividing the half life value at 12 hours by 2.

Output:

Enter the initial value:100

After 6 hours: 50.000000 mg

After 12 hours: 25.000000 mg

After 18 hours: 12.500000 mg

Which bus slot provides highest video performance

Tresset [83]

Answer:

The best slot to use for video cards is the PCI-Express x16 slot. The next best is the AGP slot. The next best is a PCI-Express x1 slot but video cards which fit that slot are very hard to find as of late 2006. The worst choice for a video card is a PCI slot.

Andru [333]

Answer:

The following are the code to this question:

code:

System.out.println(x); //use print method to print value.

Explanation:

In the given question, it simplifies or deletes code in the 11th line. This line has a large major statement.

In the case, the tests fail because only 1 line of output is required by the tester, but two lines are obtained instead.

It's to demonstrate that the input/output or testing requirements function throughout the model.
