Answer:
The data-link layer
Explanation:
The physical layer and data-link layer are often confused a lot especially in terms of what they do in the TCP/IP 7 layer protocol. The physical layer as the name suggests represents the physical devices like the cables and the connectors that join or interconnect computers together. This layer is also responsible for sending the signals over to other connections of a network. The data-link, on the other hand, translates and interprets these sent binary signals so that network devices can communicate. This layer is responsible in adding mac addresses to data packets and encapsulating these packets into frames before being placed on the media for transmission. Since it resides in between the network layer and the physical layer, it connects the upper layers of the TCP/IP model to the physical layer.

Explanation:
The following code is written in Java. It creates the Bug class with the position and direction variables. Then it creates a constructor, move method, turn method, and getPosition method. Finally, a bug object called bugsy is created in the main method, and we move it once to the right, then again to the right, and then we turn it and move it 5 times to the left, printing out the position when it is done moving. Output can be seen in the attached picture below.
class Brainly {
public static void main(String[] args) {
Bug bugsy = new Bug(10);
bugsy.move();
System.out.println("Current bug position: " + bugsy.getPosition());
bugsy.move();
System.out.println("Current bug position: " + bugsy.getPosition());
bugsy.turn();
bugsy.move();
bugsy.move();
bugsy.move();
bugsy.move();
bugsy.move();
System.out.println("Current bug position: " + bugsy.getPosition());
}
}
class Bug {
char direction = 'r';
int position = 0;
public Bug(int initialPosition) {
this.position = initialPosition;
}
public void turn() {
if (this.direction == 'r') {
this.direction = 'l';
} else {
this.direction = 'r';
}
}
public void move() {
if (this.direction == 'r') {
this.position += 1;
} else {
this.position -= 1;
}
}
public int getPosition() {
return this.position;
}
}
Answer:
Here the statement is false.
Explanation:
In C/C++, we can define multidimensional arrays in simple words as an array of arrays. Data in multidimensional arrays are stored in tabular form (in row-major order).
General form of declaring N-dimensional arrays:
data_type array_name[size1][size2]....[sizeN];
data_type: Type of data to be stored in the array.
Here data_type is valid C/C++ data type
array_name: Name of the array
size1, size2,... ,sizeN: Sizes of the dimensions.
Foe example:
Two dimensional array:
int two_d[10][20];
Three dimensional array:
int three_d[10][20][30];
The device is ; a modem.
Hope this helps
