Answer
Directory Services
<u></u>
<u>Definition</u>
It is a type of software that is used to unify and customize the resources available at the network.
<u>Explanation</u>
This software is used to gather the information and addresses of all computers connected on the network.
It is a type of information store, where all the information related to resources (computer) and services of network has been stored. It also gives administrator rights to the single point to manage whole network resources.
This is the reason, Option "D" is the best choice for me as sole IT employ in a company. I will prefer directory services software to gather the information of all computers of organization and manage users in company.
Answer:
None of the options is correct.
Explanation:
One of the simplest statements that you can write in Python is a print statement, which causes a message to be displayed on the screen. For example, the following statement causes the message Python programming is fun! to be displayed:
print 'Python programming is fun!'
Notice that after the word print, the Python programming is fun! was written inside a set of single-quote marks. The quote marks are necessary, but they will not be displayed. They simply mark the beginning and the end of the text that we wish to display.
Here is an example of how you would type this print statement at the interpreter’s
prompt:
>>> print 'Python programming is fun!'
After typing the statement you press the Enter key and the Python interpreter executes the statement, as shown here:
>>> print 'Python programming is fun!'
Python programming is fun!
>>>
Thus, the correct way to write the codes in the question is:
print 'Programming is fun'
print 'Python'
print 'Computer Science'
Answer:
// here is code in C++
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
int n,no_open=0;
cout<<"enter the number of lockers:";
// read the number of lockers
cin>>n;
// initialize all lockers with 0, 0 for locked and 1 for open
int lock[n]={};
// toggle the locks
// in each pass toggle every ith lock
// if open close it and vice versa
for(int i=1;i<=n;i++)
{
for(int a=0;a<n;a++)
{
if((a+1)%i==0)
{
if(lock[a]==0)
lock[a]=1;
else if(lock[a]==1)
lock[a]=0;
}
}
}
cout<<"After last pass status of all locks:"<<endl;
// print the status of all locks
for(int x=0;x<n;x++)
{
if(lock[x]==0)
{
cout<<"lock "<<x+1<<" is close."<<endl;
}
else if(lock[x]==1)
{
cout<<"lock "<<x+1<<" is open."<<endl;
// count the open locks
no_open++;
}
}
// print the open locks
cout<<"total open locks are :"<<no_open<<endl;
return 0;
}
Explanation:
First read the number of lockers from user.Create an array of size n, and make all the locks closed.Then run a for loop to toggle locks.In pass i, toggle every ith lock.If lock is open then close it and vice versa.After the last pass print the status of each lock and print count of open locks.
Output:
enter the number of lockers:9
After last pass status of all locks:
lock 1 is open.
lock 2 is close.
lock 3 is close.
lock 4 is open.
lock 5 is close.
lock 6 is close.
lock 7 is close.
lock 8 is close.
lock 9 is open.
total open locks are :3
Answer:
function validateForm(event)
{
event.preventDefault();
var phoneNumber = form.phoneNumber.value;
var userName = form.userName.value;
if(phoneNumber.length!=10)
console.log("Phone Number is Invalid");
if(userName.length<11)
console.log("User Name is Invalid");
}
