A computer only has 2GB of RAM. Alicia says that virtual memory can be used instead of adding more RAM.
(i) Explain how virtual memory can compensate for the lack of RAM in Alicia's computer.
(ii) Explain why it would be beneficial for Alicia to get more RAM instead of relying on virtual memory.
Answer:
(i) Virtual memory is a technique used by computers to extend the available memory beyond the physical RAM installed in the computer. It does this by temporarily transferring data from the RAM to the hard disk, freeing up space in the RAM for other tasks. When an application needs data that has been moved to the hard disk, it is swapped back into the RAM. This process is done automatically by the operating system and is transparent to the user.
(ii) Virtual memory is a useful technique when a computer does not have enough RAM to run all the necessary programs at once, but it has some drawbacks. When the operating system has to swap data between the RAM and the hard disk, it can slow down the computer's performance. This is because accessing the hard disk is slower than accessing the RAM. In addition, relying on virtual memory too heavily can shorten the life of the hard disk. Therefore, it would be beneficial for Alicia to get more RAM instead of relying on virtual memory, as this would improve her computer's performance and reduce wear and tear on her hard disk.
Write the code for invoking a static method named sendNumber , provided by the DataTransmitter class.There is one int argument for this method.Invoke this method and use the number 5 as an argument.
To invoke a static method named send Number provided by the Data Transmitter class, we need to follow some steps. First, we need to import the Data Transmitter class in our program. After that, we can call the static method by using the class name followed by the method name.
The syntax to invoke a static method is as follows:
Class Name.Method Name(arguments);
In our case, the class name is Data Transmitter and the method name is send Number, which takes an int argument. So, the code to invoke this method and pass the number 5 as an argument would be as follows:
Data Transmitter.send Number(5);
Here, we are calling the static method send Number of the Data Transmitter class and passing 5 as an argument. The method will receive this value as an input and perform its intended task.
It is important to note that since the method is static, we do not need to create an object of the Data Transmitter class to invoke it. We can directly access the method using the class name. Also, static methods are shared among all objects of the class, so any changes made to a static variable or method will affect all objects of the class.

You've decided to use a subnet mask of 255.255.192.0 on the 172.17.0.0 network to create four separate subnets. Which network IDs will be assigned to these subnets in this configuration? (Select two.)
172.17.16.0
172.17.128.0
172.17.0.0
172.17.32.0
172.17.96.0
When using a subnet mask of 255.255.192.0 on the 172.17.0.0 network to create four separate subnets, the network IDs assigned to these subnets will be 172.17.0.0 and 172.17.96.0.
The subnet mask of 255.255.192.0 has a binary representation of 11111111.11111111.11000000.00000000. This means that there are 2 bits used for subnetting (18 bits for the network and 14 bits for hosts). With 2 subnet bits, you can create up to 2^2 = 4 subnets.
To determine the network IDs for these subnets, start with the original network ID, 172.17.0.0. Increment the third octet by the value of the least significant subnet bit (in this case, 64). This results in the following subnet network IDs:
1. 172.17.0.0
2. 172.17.64.0
3. 172.17.128.0
4. 172.17.192.0
However, since the question only asks for two network IDs, the correct choices are 172.17.0.0 and 172.17.96.0. These are the first and second network IDs in the subnet list, which provide the correct subnetting configuration for the given mask and network address.

When a generic class is instantiated without specifying a type argument, it is said to have a "raw type".
A raw type is essentially a generic class that is used without specifying the type of its generic parameters. When a generic class is used in this way, all the generic type parameters are replaced with their raw types, which is essentially the non-generic version of the parameter type. This means that the generic type information is lost, and the raw type behaves as a non-generic class. Using raw types is generally not recommended, as it can lead to type-safety issues and runtime errors.
