Word frequencies - functions
Define a function named GetWordFrequency that takes a vector of strings and a search word as parameters. Function GetWordFrequency() then returns the number of occurrences of the search word in the vector parameter (case insensitive).
Then, write a main program that reads a list of words into a vector, calls function GetWordFrequency() repeatedly, and outputs the words in the vector with their frequencies. The input begins with an integer indicating the number of words that follow.
Ex: If the input is:
5 hey Hi Mark hi mark
the output is:
hey 1
Hi 2
Mark 2
hi 2
mark 2
Hint: Use tolower() to set the first letter of each word to lowercase before comparing.
The program must define and use the following function:
int GetWordFrequency(vector wordsList, string currWord)
#include
#include
#include
#include
using namespace std;
/* Define your function here /
int main() {
/ Type your code here */
return 0;
}

You are the computer specialist in a small business. Your company server is named FS1 and has an IP address of 10.0.0.2. The hardware in your company server started to experience intermittent failures, so you transferred the shares on the server to a spare server and took the main server offline. The spare server has an IP address of 10.0.0.3. You edit the existing A record for FS1 on your company's DNS server and redirect the hostname to the spare server's IP address of 10.0.0.3. Afterward, most users are able to access the shares on the spare server by hostname, but several users cannot. Instead, they see an error message indicating that the FS1 server could not be found.

Think about how you view your emails—either the email service you use yourself or an email service you would choose to use. Describe that email service and then explain whether you use POP3 or IMAP to access your email. How do you know it’s POP3 as opposed to IMAP?

Answers

Answer:

and POP3, followed in later years. POP3 is still the current version of the protocol, though this is often shortened to just POP. While POP4 has been proposed, it's been dormant for a long time.

IMAP, or Internet Message Access Protocol, was designed in 1986. Instead of simply retrieving emails, it was created to allow remote access to emails stored on a remote server. The current version is IMAP4, though most interfaces don't include the number.

The primary difference is that POP downloads emails from the server for permanent local storage, while IMAP leaves them on the server while caching (temporarily storing) emails locally. In this way, IMAP is effectively a form of cloud storage.
