Chapter 9, Problem 67E
Explanation of Solution
Data type:
- A set of data or variables with the values are referred to as data type.
- It determines the possible values or contents for that data type.
- It is used to perform the operations on the values of that data type.
Some of the data types used in a
Integer type:
Integer data type is a data type which represents the integer range from -2,147,483,648 to 2,147,483,647 values.
Example:
int x = 8;
Here, “x” is the integer variable and the value “8” is assigned to that variable.
Real type:
The range of real numbers from -3.4E+38 to +3.4E+38 values are represented by the real data type. Mostly, the computers use a rational approximation to a real number...

Challenge: Assume that the assigned network addresses are correct. 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…

- I 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_forward1. [30 pts] Match the items on the left with the memory segment in which they are stored.
