Chapter 5.8, Problem 5.1ARQ
Explanation of Solution
Purpose of the
The main purpose of the database is keeping track of things.
- It is a tool that is used to organize large amount of data.
- It is used in storing and transforming the data into information that can be used to support decision making.
Circumstance where a database is preferred with spreadsheets:
- Generally spreadsheets are also used to track things, the circumstance where a database is preferred with spreadsheets are when more information needs to be processed to obtain a certain decision.
- Spreadsheets are limited when more details regarding the data collected needs to be added.
- In that case database is preferred when more data needs to be added to calculate.
Example:
- The student information can be tracked and kept based on the course information.
- Marks the students secured in each subject can be recorded and tracked using spreadsheet, but if more information regarding the student needs to be recorded and manipulated, database will be the choice when preferred with the spreadsheets.
- Database can handle more data as compared to spreadsheet and could be presented at a single place to the user...

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…

Create a FAT filesystem on the hard drive using mkfs. fat. Be careful to use your new 2GiB drive! It would be a good idea to use 1sblk to verify the block device name before proceeding. Mount the new hard drive at a mount point of your choice. Find a book from Project Gutenberg by an author whose last name begins with the same letter as your last name (look under "Browsing Options" and then "Authors" A-Z).

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.

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
