Reflection:
What data can an IP Packet Contain?
The data that an IP packet contains is the information that will help carry the packet, to its destination. This is called the IP header. IT consists of the version, IHL, Type of service, packet length, Identification, flag, fragment offset, time to live, protocol, Header Checksum, Source Address, Destination address, Options, and padding. All of these will determine where the packet will go.
What is meant by the phrase "the IP packet is routed"?
What this means is that the packet is headed to the destination.
What is a Route?
A route is the path in which the packet takes to get to its destination
Where might things go wrong?
Things can go wrong if your internet connection has issues, and the header would not send.

4.6.1: Skills integration Challenge-Analyzing the Applications and Transport Layers
Reflection: Can you make a diagram of the sequence of protocol events involved in requesting a web page using a URL?
Sender : HTTP --> TCP ; HTTP --> IP ; TCP ; HTTP --> Ethernet ; IP ; TCP ; HTTP --> Electric impulse
Receiver: (Cont.) --> Ethernet ; IP ; TCP ; HTTP --> IP ; TCP ; HTTP --> TCP ; HTTP --> HTTP
Where might things go wrong?
Things might go wrong in the Transport Layer or the Network layer, because those are Layers that are more prone to having an issue.
Compare and contrast DNS and HTTP, and UDP and TCP.
DNS is the alias for the website. Websites were originally suppose to be typed in through IP addresses. Instead of IP addresses, you can type in the "website" such as google.com
HTTP is Hyper text Transfer protocol. This is the protocol in which browsers come in.
--------
TCP connection is connection based, its reliable, and it has flow control
UDP connection is connectionless, unreliable, but low overhead
--------
In this Lab, I observed how four different services work together in a network. the four services were DNS, UDP, HTTP, and TCP.

3.5.1: Skills Integration Challenge-Configuring Hosts and Servers
First I added a PC with the display name of 1B to the network. I configured it with the settings the lab said. We then connected the Eagle Server to the Fast access port on the R1-ISP router. We tested the connectivity, in realtime, by using a simple PDU in order to test a connectivity between PC 1B and Eagle_server.
Can you now explain the process that occurs when you type a URL into a browser and a web page returns?
The web page sends a request to the router, the router then sends a request to the internet. The internet sends a request to the server that the webpage is trying to reach. The server sends it back, all the way to the browser, then the page is finally open.
What types of client-server interactions are involved?
The client is requesting data from the server in order to visit the web-page.

Lab 2.7.1 Skills Integration Challange-Examining Packets
In this lab, we have tested sending packets from one device to another. First we have tried to send a packet from PC- PT 1B, to Server-PT Eagle_server. At first it had failed several times. There was an issue with connecting the packet from the R2-Central Router to the R1-ISP. I needed to configure each device properly until the packet successfully passed through them. After I finished sending Packets in Simulation mode, then I started experimenting with more packets. If something did not send properly, then I needed to configure it until it did send properly
HANDOUT #1
a. How does this video relate to you and this class?
This video inspires me to get more into programming. It relates to this class because it expands our knowledge and understanding in technology. We will be able to create our own business using our knowledge in networking and programming. We could possibly use our knowledge in programming to create an app, and that app will be able to connect with other people who have the app via internet
b. Why is it a good reflection of self discipline?
This is a good reflection of self discipline, because this boy followed what he really wanted to do in life, so he just decided to take action. He had not hesitated since he is still young.
c. Is this subject as easy as creating an app? WHY?
This subject is harder than creating an app. Programming is a little simpler than networking. There are so many dimensions to networking, which is why it requires so many years of classes
