Answer:
Physical and data link layer.
Explanation:
The ethernet cable is used at the physical layer. The physical layer consists of hardware components. This layer is responsible for transmission of data bits between two nodes via a physical wire. The data link layer provides the means in which data packets are transmitted from one node to another.
Suppose two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, the packets would be sent from computer A to computer B if computer B is free if not it would wait until computer B is not transmitting before it can start sending data packets to computer B.   
 
        
             
        
        
        
Answer:
- var today = new Date();
- var dateComp = [];
- dateComp[0] = today.getDate();
- dateComp[1] = today.getMonth();
- dateComp[2] = today.getFullYear();
- 
- switch(dateComp[1]){
-     case 0:
-         console.log("Jan " + dateComp[0] + "," + dateComp[2])
-         break;
-     case 1:
-         console.log("Feb " + dateComp[0] + "," + dateComp[2])
-         break;
-     case 2:
-         console.log("Mar " + dateComp[0] + "," + dateComp[2])
-         break;
-     case 3:
-         console.log("Apr " + dateComp[0] + "," + dateComp[2])
-         break;
-     case 4:
-         console.log("May " + dateComp[0] + "," + dateComp[2])
-         break;
-     case 5:
-         console.log("Jun " + dateComp[0] + "," + dateComp[2])
-         break;
-     case 6:
-         console.log("Jul " + dateComp[0] + "," + dateComp[2])
-         break;
-     case 7:
-         console.log("Aug " + dateComp[0] + "," + dateComp[2])
-         break;
-     case 8:
-         console.log("Sept " + dateComp[0] + "," + dateComp[2])
-         break;
-     case 9:
-         console.log("Oct " + dateComp[0] + "," + dateComp[2])
-         break;
-     case 10:
-         console.log("Nov " + dateComp[0] + "," + dateComp[2])
-         break;
-     case 11:
-         console.log("Dec " + dateComp[0] + "," + dateComp[2])
-         break;
- }
Explanation:
The solution code is written in JavaScript.
Firstly, create a Date object (Line 1). The date object will automatically capture the current date and time. 
Next create an array dateComp to hold the day, month and year (Line 3 -5). We use the getDate method to get current day, getMonth method for current month and getFullYear method for current year.
This is important to note that the getMonth method will return the value range from 0 - 11 with the Jan is represented as 0, Feb is 1 and so forth. Presume we intend to display the date using the format "month day, year", we can create a switch structure to check the month value which is range from 0 to 11. If month value is 0, generate string Jan + current day + "," + current year. We generate the date string based on different switch cases (7 - 44). We shall see the output similar to the date string as shown below:
 Apr 12,2020 
 
        
             
        
        
        
If a robot is able to change its own trajectory as per the external conditions, then the robot is considered the intelligent option (A) is correct.
<h3>What is AI?</h3>
Unlike the natural intelligence exhibited by animals, including humans, artificial intelligence is a form of intelligence demonstrated by robots.
The question is incomplete.
The complete question is:
If a robot can alter its own trajectory in response to external conditions, it is considered to be:
A. intelligent
B. mobile
C. open loop
D. non-servo
E. None of the above
Robots are regarded as intelligent if they can alter their own course in response to environmental factors. These kinds of agents fall into the AI agent or Rational Agent group.
Thus, if a robot is able to change its own trajectory as per the external conditions, then the robot is considered the intelligent option (A) is correct.
