Code.org CSP Unit 1 Stages 11-13 Watch the corresponding videos and answer the questions below. Make sure to answer the questions for each stage within Code.org. Stage 11 Video Guide - The Internet – Packets, Routing & Reliability ⦁ Does information always follow a fixed path on the Internet? No it takes the most efficient path and that path changes. ⦁ What is done to information to send it from one location to another on the Internet? It is broken into packets that travel across the internet and the packets take the most avaiable and efficient path and eventually all come together where they are suppose to be. ⦁ What kinds of information can be sent with IP packets? Almost any of the information sent over the internet can be sent with IP …show more content…

Fault tolerance is the property that enables a system to continue operating properly in the event of a failure. ⦁ What does TCP mean? TCP is a set of rules that governs the delivery of data over the internet or other network that uses the Internet Protocol, and sets up a connection between the sending and receiving computers. ⦁ What is TCP used for? TCP can be used as a communcations protocol in a private network but it is the basic communication language or protocol of the Internet. Stage 12 Video Guide - The Internet – IP Addresses & DNS ⦁ What is the Internet? The Internet is a global computer network providing a variety of information and communications facilities, consisting of interconnected networks using standardized communcation protocols. ⦁ Define Protocol: A Protocol is a set of rules or procedures for transmitting data between electronic devices, such as computers. In order for ocmputers toe xchange information, there must be a preexiting agreement as to how the information will be structered and how each side will send and recieve it. ⦁ What does IP stand for and what is it used for? Internet Protocol, and it's a set of rules governing the format of data sent over the Internet or other …show more content…

Two of the pairs of two represent network and host, One identifies the network an the second part indentifies the node, or host. ⦁ Why are we switching to IPv6? We are switching to IPv6 because there isnt enough IP adresses, IPv4 has around 4 billion adresses and IPv6 will have many more than that. ⦁ Define DNS: DNS or Doman Name System is the internet's system for converting alphabetic names into numeric IP adresses. For example, when a Web address or URL is typed into a browser, DNS servers return the Ip address of the Web server associated with that name. ⦁ What is a problem with DNS? There is DNS spoofing and DNS hijacking both usually done by hackers, and they could direct users to websites containing malware or a third-party search engine or just corrupt DNS data in general. Stage 13 Video Guide - The Internet - HTTP & HTML ⦁ What does HTTP stand for and what is used for? HTTP stands for Hypertext Transfer Protocol, it is the protocol over which information is sent from a user's web browser to the website they are visiting ⦁ How does a get request work? HTTP protocol works in a client and server model like many other protocol. A web browser using which a request is initiated is called as a client and a web server software which respond's to that request is called as a

    The internet works on the basis that some computers act as ‘servers’. These computers offer services for other computers that are accessing or requesting information, these are known as ‘clients’. The term “server” may refer to both the hardware and software (the entire computer system) or just the software that performs the service. For example, Web server may refer to the Web server software in a computer that also runs other applications or it may refer to the computer system dedicated only to the Web server applicant. For example, a large Web site could have several dedicated Web servers or one very large Web server.

    In the networking of computers and devices, the Internet Protocol (IP) plays a very important role. The IP, found at the internet layer of the Department of Defence (DoD) model provides the means for the devices to communicate using logical addresses called IP addresses. The importance of an IP address to communication will be felt in the analogy of a surface mail. How possible would it be to send a letter to someone whose address we do not know? The IP address enables us to know the source of a packet and the destination for proper delivery by the IP protocol.

  • The Transition From IPv4 to IPv6

    When putting a stack into an example, one can relate the mail system. The application layer would include the writer and letter being sent. Since the writer is busy, the writer sends someone to put the mail in the mailbox which would be the transport layer. The next layer, the network layer, would be the actual address of the mailbox. Lastly, the physical layer is the process of getting the mail to the destination by stopping at other destinations such as the mail center, airport, and the post office. Each step is important in the process of making this work. However, there is a current problem that is being solved and it relates with the network layer. IP is the most commonly used tool in the network layer but the amount of addresses are running out. Before getting into the details of why that is happening. What exactly is IP?

  • TCP/Ip Application Layers Analysis

    In each application layer TCP/IP is required to make sure that there is connection between the networks that are communicating with each other and they have to make some kind of connection like a bridge between them. When the connection is made IP is stuck on to the data packet which is sent to the receiver which includes the information about the sender and the receiver e.g. the IP address of the sender which is like your home address so it can be tracked down as well as the destination of the other network so without TCP/IP the data packets would go to the internet and they would not get to their destination they would flow inside the WWW lost without a destination. TCP/IP is a crucial part of web architecture and internet itself. Without TCP/IP protocols we would not be able to use the internet.

    Although initially conceived as a form of communication during wartime, developed by United States Department of Defense. The precursor of the Internet was created by a group called, The Advanced Research Projects Agency Network (ARPAnet), as a distributed communication network (Richard Campbell, 2013)in case of a nuclear catastrophe, ARPAnet was in principle just a form of communication from one point to another which had users log into what they called a network, thus allowing for information to be shared whenever necessary. The way information was able to travel from one location to another within a network was in broken down form of compressed data called packet switching. “This is a method of breaking data files into small packets or chunks in order to send them across a network” (Teach-ICT.com Limited, 2002). This was in fact, laying out the outsets of what was then to become, the Internet.

    Next, the writer goes over the second type of network architecture - the TCP/IP reference model, the granddaddy of the wide area computer network. This architecture allows the connection of multiple networks seamlessly. The architecture is flexible and capable of running even if some of the subnet hardware is destroyed or non-functional as long as the source and destination machines are functioning. In a similar fashion to the OSI model, the TCP/IP model has layers as well. In this case, we have four layers: the link

  • Communication Protocols and Network Devices

    There can be an assortment of devices on a network depending on the size. These devices need an effective method of communication between themselves in order to relay the information to the correct destination. The communication protocols are a set of standards that tell different hardware and software how to transfer data elements between them. When working with the OSI model, the protocols will govern communication between entities on the same reference model layer. Network protocols include mechanisms for devices to identify and make connections with each other, as well as formatting rules that specify how data is packaged into messages sent and received (Mitchell, 2014). If devices are using different protocols, they cannot understand each other in order to successfully transmit and receive data.
