Answer:
The answer to this question is given below in the explanation section.
Explanation:
When you will run the given code of java in this question. You will get an error and nothing will get printed in the response of the result. Because, in Java, you can't add the two array objects. The reason behind it, java does not support operator overloading. You cannot use the plus operator to add two arrays in Java
. It will give you the compile-time error.
There is a method to add two arrays in the Java program is to iterate over them and add individual elements and store them into a new array. This also becomes complex, if you having arrays of different sizes. To go through this method, you have to build a method that will through an illegal exception in case of a mismatch in the sizes of the arrays.
As in the given code, when you execute the first print statement:
System.out.println(num1.get(0)+1);
It will produce error because first type is object and second is int. So, you cannot add object and int value.
When you will execute the given second print statement:
System.out.println(num1.get(1)+ num2.get(0));
it will also produce error, because you cannot add object in Java using + binary operator because in this statement first and second type are both objects.
<u>Switches</u> increase network performance by reducing the number of frames transmitted to the rest of the network.
Switches are an integral part of networks assigned the role to serve as the means to share information among different devices.
Switches perform their function by supervising and controlling the flow of data to the intended devices thus preventing the undesired flow of data to all the devices in a network which improves the performance of the network. Switches can also play a role to prevent errors as it checks the data prior to transmitting the data forward.
Switches determine the devices to which the data packets are to be sent by using their media access control (MAC) address. All hardware units connected to a system have their unique MAC address. Switches identify the MAC address of the device that sends the frames and then interpret the MAC address of the target device thus preventing the frames to pass towards the rest of the network.

Answer:
Colleges care a lot more about your math skills than computer stuff, even for computer science. Make sure you still do some computer science stuff (esp. if it's extracurricular) but focus on improving your math.
