Stack
Networks & Internet - HS Student
Credits
0 High School Credit

Description

Through a project, students demonstrate their understanding of how devices communicate across networks to share information. Additionally, students must show their learning of how computers connect them to other people, places, and things worldwide in the early grades.

Standards
  • Wyoming Content and Performance Standards > Network Communication & Organization
    L1.NI.NCO.01 - Evaluate the scalability and reliability of networks, by describing the relationship between routers, switches, servers, topology, and addressing.
How To Earn This Microcredential

Design and complete a project proving your knowledge of the High School Level 1 Network Communication & Organization Computer Science standard.

It is recommended you combine this work with the other Networks & the Internet standard of Cybersecurity. It is also recommended that you connect this work with Computer Science Practice 4, Developing and Using Abstractions. However, this MC may be earned on its own as well.

Fees
There will be no fee assessed for reviewing this microcredential.
Clarifications

Each device is assigned an address that uniquely identifies it on the network. Routers function by comparing IP addresses to determine the pathways packets should take to reach their destination. Switches function by comparing MAC addresses to determine which computers or network segments will receive frames. Students could use online network simulators to experiment with these factors.

Important Terms
Abstractions:

(Process): The process of reducing complexity by focusing on the main idea. By hiding details irrelevant to the question at hand and bringing together related and useful details, abstraction reduces complexity and allows one to focus on the problem. (Product): A new representation of a thing, a system, or a problem that helpfully reframes a problem by hiding details irrelevant to the question at hand. [MDESE, 2016]

Addressing:

The code that identifies where a piece of information is stored.

IP Addresses:

A unique string of characters that identifies each computer using the Internet Protocol to communicate over a network.

MAC Addresses:

A MAC address (media access control address) is a 12-digit hexadecimal number assigned to each device connected to the network. Primarily specified as a unique identifier during device manufacturing, the MAC address is often found on a device's network interface card (NIC).

Network:

A group of computing devices (personal computers, phones, servers, switches, routers, etc.) connected by cables or wireless media for the exchange of information and resources.

Reliability :

Consistently produces the same results, preferably meeting or exceeding its requirements. [FOLDOC]

Routers:

A computer that is a gateway between two networks at OSI layer 3 and that relays and directs data packets through that inter-network. The most common form of router operates on IP packets.

Scalability :

The capability of a network to handle a growing amount of work or its potential to be enlarged to accommodate that growth. [Wikipedia]

Servers:

A server is a computer program or device that provides a service to another computer program and its user, also known as the client. In a data center, the physical computer that a server program runs on is also frequently referred to as a server.

Switch:

A high-speed device that receives incoming data packets and redirects them to their destination on a local area network (LAN). [Techopedia]

Topology:

The physical and logical configuration of a network; the arrangement of a network, including its nodes and connecting links. A logical topology is the way devices appear connected to the user. A physical topology is the way they are actually interconnected with wires and cables. [PCMag]

Background Scenario / How This Will Help You

You can choose your own ideas for projects that demonstrate how to recognize and define computational problems. Possible project ideas could include:

  1. Design your own network security company. Create a website, flyers or a sales pitch for an interested client that includes the comparison of various security measures and their tradeoffs of usability and security, and that will discuss the scalability and reliability of your network of routers, switches, servers, topology, and addressing.
  2. Identify a current network security need in your community. Evaluate multiple network security companies and create a report that evaluates their scalability and reliability and other security measures. Then create a report recommending the best one to that community partner.
Evidence Options
Be sure to submit the type and number of pieces of evidence specified below.
Category: Evidence

This is where you will submit your evidence to demonstrate that your project shows how you met the Computer Science Practice 3 - Recognizing and Defining Computational Problems.

Submission of this evidence is required. You must submit the Student Submission ALgorithms and Programming CS Micro-credential Stack document.

Student Work:

You will want to submit the information on the Student Submission Computing Systems CS Microcredential Stack document. You will need to complete the information on either the Google Docs or Word Version. Make sure you submit your documents as a PDF.

You can find the Google Docs Version of the template here: https://bit.ly/HS_Student_NI_SW.

This checklist will help you review your submission materials to ensure you address everything that is expected for this micro-credential: https://bit.ly/HS_Student_NI_CL.

Evidence submissions will be reviewed for alignment with the assignment guidelines and this proficiency scale: Novice Developing Applying
The student’s project provides little to no evidence in addressing the expectation(s). The student’s project: (1) Identifies routers, switches, servers, topology, and addressing. (2) Defines routers, switches, servers, topology, and addressing. The student’s project: (1) Describes the relationship between routers, switches, servers, topology, and addressing. (2) Evaluates the scalability and the reliability of networks.

A three-episode arc on the rise of a global telecommunications network that changed the world forever. We’re going to begin with computer networks, and how they grew from small groups of connected computers on LAN networks to eventually larger worldwide networks like the ARPANET and even the Internet we know today. We'll also discuss how many technologies like Ethernet, MAC addresses, IP Addresses, packet switching, network switches, and TCP/IP were implemented to new problems as our computers became ever-increasingly connected. Next week we’ll talk about the Internet, and the week after the World Wide Web!
