In this question the option b,c, and d are correct.

Explanation:

A (DBMS) stands for a database management system. The DBMS is a software package that is used for crate, update, and delete. The database uses the SQL which stands for the structured query language. It is a programming language that uses the queries. These queries are used to providing many operations in the database like crate table, update table, join table, create a view of the table, etc. In the database, we can view the code of the join table and is also used to hide the complexity of retrieval operations, it can help in the update the table in a single statement.

Romashka-Z-Leto [24]

Answer:

The method in C++ is as follows:

double average(int v, int w, int x, int y, int y){

   double ave = (v+w+x+y+z)/5.0;

   return ave;

}

Explanation:

This defines the average method with 5 parameters

double average(int v, int w, int x, int y, int y){

This calculates the average

   double ave = (v+w+x+y+z)/5.0;

This returns the calculated average

   return ave;

}

To call the method from the program's main, use:

<em>int main(){</em>

<em>    cout<<average(1,5,7,4,10);</em>

<em>    return 0;</em>

<em>}</em>

Which binary signaling technique uses a scheme in which zero voltage represents a 0 bit and the voltage for a 1 bit does not dro
prisoha [69]

Answer:

In binary signaling, Non Return to Zero (NRZ) is the technique in which zero voltage is represented by 0 bit while high voltage is represented by 1 until the voltage level change from high to low.

Explanation:

There are different techniques to encode the signal for transmission between transmitter and receiver. These techniques includes return to zero, non return to zero. In return to zero technique, the if the voltage is high the signal will become 1 for half of the time period and then after half time period it return to 0.

In NRZ the signal is 0 if the voltage level is zero. In case of high voltage of the signal the binary bit remains 1 until the next zero voltage level arrive in the signal until the end of the time period of bit.

gayaneshka [121]

Answer:

Creative Commons is actually a license that is applied to a work that is protected by copyright. It's not separate from copyright, but instead is a way of easily sharing copyrighted work. ...
