The twelve principle are:
- The first rule of the relational database is the information rule as it represented all data or information
- Independence of the integrity
- Viewing various updating rule
- Logically treatment of various NULL value
- Independence of the physical database
- Distribution in-dependency
- Various delete, insert and update rules
- The overall logical description of the database are basically stored in the database directory
- There is no subversion rule
- There is guarantee accessing rule
- Proper rule for data language
- The relational database level actions
Answer: Stealth scanning technique
Explanation:
Stealth Scanning technique includes the following steps:
1. The client upon sending a single SYN packet to is responded by SYN/ACK packet if the port is open.
2. The port is assumed to be in closed state if the RST packe t is sent from the server.
3. This RST packet is sent by the client to close the initiation process so that a connection cannot be established.

Answer:
The code will produce:-
2.4
Explanation:
In this code the result of the arithmetic operation is stored in the variable c.On evaluating the expression it divides 12.0 by 5 which results in 2.4 and it is stored in float variable c.Then it is printed on the screen using print statement.Since the c is double variable so the result will be a decimal number.
Hence the answer is 4.
Answer:
loop
Explanation:
Loop is the one which is used to execute the specific statement again and again until the condition is true.
In the programming, there are 3 basic loop used.
1. for loop
<u>Syntax:</u>
for(initialization, condition, increment/decrement)
{
statement;
}
the above statement execute until the condition in the for loop true when it goes to false, the loop will terminate.
2. while loop
<u>Syntax:</u>
initialization;
while(condition)
{
statement;
increment/decrement;
}
it is work same as for loop and the increment/decrement can be write after or before the statement.
3. do while
syntax:
initialization;
do
{
statement;
increment/decrement;
}while(condition);
here, the statement execute first then, it check the condition is true or not.
so, if the condition is false it execute the statement one time. this is different with other loops.
