The answers are: it is used to enable fast DNS queries and It can help reduce the amount of network traffic generated by DNS servers.
Explanation:
Because a DNS server can resolve a query from tis local data sends a recursive qyery to a root server.
Answer:
The answer is "True".
Explanation:
Digital modulation is also known as a method, which uses common synchronization names and various types of signals to manipulate a carrier wave.
- The analog method measures the radio signals in amplitude and frequency.
- It provides more general usage in the firmware, that's why the answer to this question is true.
Answer:
Hi Riahroo! This is a good question on the concept of relational databases.
We can normalize the relations as follows:
Flight
(flightnumber (unique), flighttime, airline_id, departure_city, arrival_city, passenger_id, pilot_id, airplane_id)
has_one_and_belongs_to :airline
has_many :passengers
has_one :pilot
Itinerary(passenger_id, flight_id)
Belongs_to
Passenger_details
(passengername (unique), gender, date_of_birth)
has_many :flights
Pilot
(pilotname (unique), gender, date_of_birth)
has_many :flights
airline(airlinename)
airplane(planeID, type, seats))
Explanation:
To normalize a relation, we have to remove any redundancies from the relationships between database objects/tables and simplify the structure. This also means simplifying many-to-many relationships. In this question, we see there is a many-to-many relationship between flights and passengers. To resolve this we can introduce a join table which simplifies this relationship to a one-to-many between the objects.
Answer:
The correct answer to the following question will be "Math.sqrt(area*2)".
Explanation:
- The Math.sqrt( ) method in JavaScript is used to find the squares root of the given figure provided to the feature as a variable.
- Syntax Math.sqrt(value) Variables: this function takes a single variable value that represents the amount whose square root is to be determined.
- The area of the figure is the number of squares needed to cover it entirely, like the tiles on the ground.
Area of the square = side times of the side.
Because each side of the square will be the same, the width of the square will only be one side.
Therefore, it would be the right answer.
