How is it organized hierarchically?

 The four numbers are a country/ network. Then region/network followed by subnetwork/device. Those are divided by subnetwork and the specific device. 

How many bits are in an IPv4 address?

There are 32 bits in an IPv4 address

How many IPv4 addresses does that mean there are?

More than 4 billion unique  address

What is the difference between IPv6 and IPv4?

An IPv6 address is much longer than an IPv4 because there are bits added on to help keep up with the fast pace internet that will keep expanding.

Why do we need IPv6?

The internet is fastly growing and each new computer or network needs there own addresses for another computer to communicate with them or a network.

What is an IP packet?

An IP packet is saying that there are many packages coming behind me to one destination but they will not all take the same route so they send a message to the destination saying what is supposed to arrive.

What is the difference between an IP address and an IP Packet?

An IP packet has many packages coming to one place but an Ip address is how the device or a network is able to communicate or reach information.

What is the purpose of the Domain Name System(DNS)?

The purpose of the DNS is how the computer is able to access the .com, .org, and .net to their own IP addresses. In each DNS server one server can't keep up with every computer so they are many but they have divided it into their own domain. 

Koan one

Summary
In the Koan one, it was talking about how computer intercept information about the daily activities we do in our personal or school life. While coming from the perspective of a phone that the majority of the population owns one. It talks about how the apps, calls, and messages all form back into simples bits that the computer takes from one computer to another when asked to. While they are layers to how the process is done the backbone is coming back to it being bits. Also, the law mentioned in the paragraph about how what being sends should be considered more secure because of what it could be contained inside.



Question 1
While the machinery and hardware won't change much because bits are bits. The computer is going to take what the sender wants to give to the receiver and vis verrsa. While in the article it mentions that the law won't be able to catch up the communication carriage of phone and computer. The law may be able to recognize what the general consider privacy and needs to more secure. Also what happens on the computer is all from the human action the computer just transfers or storing the information it was giving.

Question 2
How this affects my daily student life is the koan one is all about that the internet and how a computer process the information from emails to calls, messages, and etc. it is all just bits to the computer. bits that need to be transferred from computer to another. In my life, I always carry out my phone and computer to school. While I am in school there is nothing in my school or personal email messages or calls that I would be ashamed about embarrassed yes but nothing I would be like omg how did they get this. I also understand to the computer it has no emotion and it seems that this email has contents and needs to be sent to this computer. In the modern world, the phone and technology are considered a communication carriage.

Quiz One Corrections

Evaluate:19 MOD 5?
 I keep answering 3.8 because I am just generally confused and it looks different from the others. I now remember that is looking for the remainder of the number is was asking for. So 5 goes in nineteen 3 times with four left over.

What Is missing from the code?
From the code, I understand that nothing was happening in the loop but it would still be able to print which is why I said don't change anything. When retaking the quiz the option was not avabile so I chose the initial value of X. In the code there was already an initial value for X. So that was a question I read to fast and did not relook at before trying it in. So the right answer was "a statement to change the value of X while in the loop". Which is correct because every other answer was correct. Also looking back the code would run on forever because X won't change.

What is the highest decimal value a single byte of data can hold?(255)

1. With this question, I keep thinking that a single byte is the first eight digits compared to the first four digits that represent 1,2,4, and 8. This question is just about me remembering the basic.
