Answer:
The definition of function is as follows:
def typing_speed(number_of_words,Time_Interval):
number_of_words>=0
Time_Interval>0
speed=float(60*number_of_words/Time_Interval)
return speed
Explanation:
Above function is defined step-by-step as follows:
def typing_speed(number_of_words,Time_Interval):
- A function named typing speed has two arguments, num_of_words and Time_Interval.
number_of_words>=0
Time_Interval>0
- The variable number_of_words is the number of words entered that a person enters, they must be greater than or equal to 0. Where as Time_Interval is the variable for counting the time span in seconds, it must be greater than 0.
speed=float(60*number_of_words/Time_Interval)
return speed
- For determining result firstly the seconds are converted int minutes by multiplying with 60 and number_of_words is divided with Time_Interval in order to get words per minute. The return value will give speed which has data type float.
Answer:
SAN
Explanation:
A Storage Area Network (SAN) is a high-speed sub network of shared storage devices. A SAN's architecture works in a way that makes all storage devices available to all servers on a LAN or WAN. As more storage devices are added to a SAN, they too will be accessible from any server in the larger network.
Answer:

Explanation:
public class Card
{
String Suit;
int value;
public Card(int value, String Suit) {
self.value = value;
// Check Suits value
if ((Suit == "hearts") || (Suit == "spades") || (Suit == "clubs") || (Suit == "diamonds"))
self.Suit = Suit;
else {
Suit = "none";
throw new IllegalArgumentException("no card of this type exists.");
}
}
public String getSuit() {
return Suit;
}
public int getValue() {
return value;
}
public void print() {
System.out.println("%d of %s", value, Suit);
}
}
public class Deck {
}
