Chapter 1, Problem 2RQ
Explanation of Solution
Entity:
Entity is the basic block for building the data collected about person, place, event, or thing.
- Entities represent attributes that can have multiple instances.
- To locate the information in the entity, they have a name, short description about what they are and identifier.
- Identifiers are used to identify each and every individual instance of an entity.
- Relationship denotes the link between the entities...

Now unmount the filesystem.
Create a sparse image file, called book.img, of the 2GiB hard drive.
Use a hexdump program to look at book.img and work out the offsets that store the contents of the
book youdownloaded. Record the offsets as a sequence of one or more ranges of hexadecimal
numbers. For example, in the following hexdump the text The rain in Spain falls mainly on the
plain. is stored at 0x10-0x1f, 0x30-0x4b (inclusive).

Compress the filesystem using gzip by running:
#gzip book.img
This should leave you with a file book.img.gz. You will use scp to transfer this file in a later task.

Task 4: Examine floppy.img
Mount floppy.img at a suitable mountpoint inside your VM.
Look inside the mountpoint directory. You should see a number of files in the top-level directory.
Look inside your answers2.json at the strings labelled contentA and contentB. Exactly one of those two strings
appears as the content of a file in the floppy disk's filesystem. I.e., there is a file that contains contentA or a file
that contains contentB but not both.
Additionally, the other string has been written into unused space of the floppy disk, so the data is in floppy.img
but cannot be seen inside any of the files at the mountpoint. However it can be seen in a hexdump of floppy.img.
I.e., if there is a file that contains contentA then contentB has been written into unused space.
You must search through your mountpoint directory to find out which of contentA and contentB is stored in a file
of the filesystem and which is stored in unused space. Suppose that contentA is stored in a file, and…

Can you deduce (guess) what the network subnet masks are? Explain while providing subnet mask bits for each subnet mask. [Hint: Look at the addresses in binary and consider the host ids] To assume that the network addresses are correct, we take a look at the network ID and IP addresses. Take 20.0.0.0/8, we have an /8 prefix which is Class A, that provide us with 255.0.0.0. This means that there are 24 host bits while the network bits are 8. When compared to the IP address 20.255.0.7, we can perform an additional operation with the subnet mask giving us 20.0.0.0. The same happened with 20.0.0.89, which we also got 20.0.0.0. Therefore, these two IP addresses fall within the respective /8 subnet. For 200.100.10.0/30, the /30 is Class C with a subnet mask of 255.255.255.252, meaning 30 network bits and only two host bits. When applying the subnet mask and the IP addresses…arrow_forwardIt is possible to sort an array of n values using pipeline of n filter processes.The first process inputs all the values one at a time, keep the minimum, and passes the others on to the next process.

Can you deduce (guess) what the network subnet masks are? Explain while providing subnet mask bits for each subnet mask. [Hint: Look at the addresses in binary and consider the host ids]arrow_forwardI would like to know if my answer statment is correct? My answer: The main difference is how routes are created and maintained across different networks. Static routing establishes router connections to different networks from the far left and far right. The Dynamic routing focus emphasizes immediate connection within the router while ignoring the other connections from different networks. Furthermore, the static routing uses the subnet mask to define networks such as 25.0.0.0/8, 129.60.0.0/16, and 200.100.10.0/30, which correspond to 255.0.0.0, 255.255.0.0, and 255.255.255.252. On the other hand, dynamic routing uses the wildcard mask to inverse the subnet mask, where network bits become 0 and host bits become 1, giving us 0.0.0.255, 0.0.255.255, and 0.0.0.3. Most importantly, the CLI commands used for Static and Dynamic routing are also different. For static routing, the “IP route” corresponds with the network, subnet mask, and next-hop IP address. In contrast, dynamic routing uses…arrow_forward
