Hands On Activity 2a Analysis

Fiddler is a notorious web-debugging tool which captures HTTP traffic between chosen computers and the internet. The incoming and outgoing data can be analysed and modified before the responses make it to the

The motor activity log, or MAL-14, consists of fourteen different activities for daily living and an assessment of the ability to do each one of these.The 14 activities are as follows:

If you have ever accessed the site before. If you have accessed it recently, the files may be in your cache and the site will load more quickly the second and consecutive times.

• Web logging, which enables us to collect the standard information your browser sends to every web site you visit - such as your IP address, browser type and language, and the site you came from - as well as the pages you visit and the links you click while using our sites and services.

Lastly, the third rule is that when the information is received from the HTTP protocol all the data should be contained in data relationships. Stating that data is relationships, meaning that all the information given in one HTTP contains all the data and relationships in a single hyperlink making everything much simpler than before. Ultimately, everything that is mentioned in these three rules all comes down to being linked data. Linked data is all the relationships and information that is used in these HTTP protocols and returns the data for easier access by using these relationships, instead of using multiple programs in order to find information based on one piece of data. Berners-Lee goes on to finish his presentation by stating that this whole process of using HTTP protocols is simply the use of linked data and the many connections involved when using this data. In another presentation, Berners-Lee discusses the idea behind modifying and implementing a user interface on web pages and how the web went worldwide. When the web was being used more often, it went worldwide, which ultimately brought up the question of how all this complex data being used everywhere was going to be tracked. Berners-Lee states that satellites are used in order to make “mash-up” maps that hold data all around the world and use a user interface in order to properly organize traffic, energy, and other important data onto these so called mash-up maps.

The internet runs on ip addresses for you pc to the servers of the world.

2. Start up the Wireshark packet sniffer, as described in the Introductory lab (but don’t yet begin packet capture). Enter “http” (just the letters, not the quotation marks) in the display-filter-specification window, so that only captured HTTP messages will be displayed later in the packet-listing window. (We’re only interested in the HTTP protocol here, and don’t want to see the clutter of all captured packets).

The World Wide Web works through the http protocol and the servers connected to the web attend requests through the internet. The URL consists of protocol in which the server retrieves the indicated document and creates a response which is sent back to the user.

The URL is the abbreviation of Uniform Resource Locator. It has the global address of documents and other resources on the World Wide Web. The URL methods are also strings of characters used to identify a resource over a network. URL protocols include HTTP (Hypertext Transfer Protocol) and HTTPS (HTTP Secure) for web resources, "mailto" for email addresses, "ftp" for files on a File Transfer Protocol (FTP) server, and telnet for a session to access remote computers. Fig.1 has shown the Google URL. The “http://” is protocol; “www” is subdomain；“google” is the domain name; “.com” is the first top-level domains based on the Domain Name System.

Every TCP packet is captured which arrives at port 80 and following operations are performed,

When you type a website name into your browser, your browser first does a lookup for the domain’s IP address. Once the IP address is found, the browser makes a request to the server for a connection. The server accepts, and then it sends you the website’s HTML for your browser to display. Let’s say you find a contact form on a website and want to send the owner a message. You type your

A PAC file resides on a server, and a browser will access the PAC file using a given URL.

Client represents web browser resides on the user’s computer. Users interact with web browser and web browser will interact with user interface of the system.

I completed my undergrad in electrical and communication engineering in 2012, but I was interested in my field since I was in high school. At that time I was using the internet for playing games, reading electronic newspapers and watching video songs on YouTube, but I did not know how it used to play on my computer. This imagination developed a spark inside me to know how this is working. I asked it to my neighbor who is also an engineer. He told me it’s related to networking field. Every site has its an own server and the server has data providing whatever data you want and due to that I was very much interested to know how data is coming on my computer and I decided I will make my future in the networking field.
