Solution:
Database integrity ensures that each row is uniquely identified by the primary key, which means that a proper search for an existing tuple (row) will always be successful.
Thus the required answer is D
Answer:
Explanation:
The code provided is written in Java. The statement is provided right under the /*Type your code here*/. In Java, in order to case one primitive to another you simply need to type the primitive type that you are trying to cast too before the variable and within parenthesis. The output of the new code can be seen in the attached image below.
class LabProgram {
public static int convert(double d){
/* Type your code here */
return (int) d;
}
public static void main(String[] args) {
System.out.println(convert(19.9));
System.out.println(convert(3.1));
}
}
Answer:
170 Mbps
Explanation:
Time taken to put data on to the link T1 = 50kB / 1 Gbps = 0.0004096
Time taken for transmission T2 = 2 milliseconds = 2 * 10-3
--> throughput = ( 1 / (1+T2/T1) ) * bandwidth of link
= ( 1 / (1 + 4.8828125) ) * 1 Gbps
= 0.16998672 * 1 Gbps
= 169.98672 Mbps
= 170 Mbps.
Answer:
Let's say you need to remember some information, the way moviegoers tried to remember the name of the movie. Instead of storing it in your human memory, you can store information in your computer's memory using Python. This is called assigning a string value to a variable.
To assign a string value to a variable in Python, follow this example. Select each part of the code to see how it works with the movie title example.
movieTitle = "Live. Die. Repeat."
This line of Python code is an example of an assignment statement. In an assignment statement, you tell Python, "This variable is assigned this string value."

Answer:
Mainframe Computer System
Explanation:
Mainframe systems or simply mainframes are computers used for critical application, bulk processing and transaction processing.
They are larger than the basic computers we find around. They are advantageous as they are able to process large data faster. For this reason, large institutions like banks tend to use them for processing of data because of the thousands of transactions they engage in.
They are capable of handling and processing very large amount of data quickly.
Examples of other large institutions that uses mainframe computers apart from Bank stated in the question are
1. Stock brokerage firms
2. Government agencies
3. Insurance agencies
4. Fortune 500 companies and so on.
