Answer:
Mac Address
Explanation:
The MAC address or Media Access Control is a unique identifier that each manufacturer assigns to their devices that can connect to the network. They consist of 48 bits in hexadecimal form, grouped into 12 pairs of characters and each character is formed by four binary numbers, generally separated by a colon. MAC addresses are used in the data link layer of the OSI model, specifically in the lower Medium Access Control layer. An example of a MAC address could be:

Answer:
Explanation:
The following is written in Java. It creates the trafficLight class which holds the currentLight string variable and a int count variable for the number of times the light has been red. It also contains two constructors one that takes the currentLight as a parameter and one that does not. Finally, it has the next() method which analyzes the currentLight status and changes it to the next light. Output can be seen in the attached picture below.
class Brainly
{
public static void main(String[] args)
{
trafficLight traffic_light = new trafficLight();
System.out.println("Current Light: " + traffic_light.currentLight);
traffic_light.next();
System.out.println("Current Light after change: " + traffic_light.currentLight);
}
}
class trafficLight {
String currentLight;
int count = 0;
public trafficLight(String currentLight) {
this.currentLight = currentLight;
}
public trafficLight() {
this.currentLight = "red";
count++;
}
public void next() {
if (this.currentLight == "green") {
this.currentLight = "yellow";
} else if (this.currentLight == "yellow") {
this.currentLight = "red";
count++;
} else {
this.currentLight = "green";
}
}
}
Answer:
B. client server
Explanation:
Someone hacked into an employees computer and erased all of their data. The employee had last performed a backup three weeks back. This means that there is a backup server in the company. In other words, the network architecture is of the form client-server where data from the employee computers is backed up to a centralized repository from where content could be restored. Hence option B represents the most likely choice.
