Students will define terms associated with computing systems and networks. All terms can be found here.
Students will demonstrate vocabulary terms within classroom demonstrations.
CSN-1.A.1: A computing device is a physical artifact that can run a program. Some examples include computers, tablets, servers, routers, and smart sensors.
CSN-1.A.7: The bandwidth of a computer network is the maximum amount of data that can be sent in a fixed amount of time.
CSN-1.A.8: Bandwidth is usually measured in bits per second.
CSN-1.A.2: A computing system is a group of computing devices and programs working together for a common purpose.
CSN-1.A.3: A computer network is a group of interconnected computing devices capable of sending or receiving data.
CSN-1.A.4: A computer network is a type of computing system.
CSN-1.A.5: A path between two computing devices on a computer network (a sender and a receiver) is a sequence of directly connected computing devices that begins at the sender and ends at the receiver.
CSN-1.A.6: Routing is the process of finding a path from sender to receiver.
CSN-1.A.7: The bandwidth of a computer network is the maximum amount of data that can be sent in a fixed amount of time.
CSN-1.A.8: Bandwidth is usually measured in bits per second.
CSN-1.B.3: A protocol is an agreed-upon set of rules that specify the behavior of a system.
CSN-1.B.4: The protocols used in the Internet are open, which allows users to easily connect additional computing devices to the Internet.
CSN-1.C.1: Information is passed through the Internet as a data stream. Data streams contain chunks of data, which are encapsulated in packets.
CSN-1.C.2: Packets contain a chunk of data and metadata used for routing the packet between the origin and the destination on the Internet, as well as for data reassembly.
CSN-1.C.3: Packets may arrive at the destination in order, out of order, or not at all.
CSN-1.C-4: IP, TCP, and UDP are common protocols used on the Internet.
CSN-1.D.1: The World Wide Web is a system of linked pages, programs, and files.
CSN-1.D.2: HTTP is a protocol used by the World Wide Web.
CSN-1.D.3: The World Wide Web uses the Internet.
CSN-1.E.2: Redundancy is the inclusion of extra components that can be used to mitigate failure of a system if other components fail.
CSN-1.E.5: When a system can support failures and still continue to function, it is called fault-tolerant. This is important because elements of complex systems fail at unexpected times, often in groups, and fault tolerance allows users to continue to use the network.
CSN-2.A.1: Sequential computing is a computational model in which operations are performed in order one at a time.
CSN-2.A.2: Parallel computing is a computational model where the program is broken into multiple smaller sequential computing operations, some of which are performed simultaneously.
CSN-2.A.3: Distributed computing is a computational model in which multiple devices are used to run a program.
Key vocabulary: Computing device, computing system, computer network, path, routing, bandwidth, Internet, protocol, open protocols, dynamic routing, scalability, data stream, packets, IP, TCP, UDP, world wide web, HTTP, fault tolerant, redundancy, sequential computing, parallel computing, distributed computing, sequential solution, parallel solution, speedup of a parallel solution
Objectives and General Description
Objectives and General Description
Vocabulary and terminology are important to any unit of instruction. The objective is to develop an understanding of the key components of this unit and to apply these concepts to the ARC challenge and to classroom demonstrations throughout Sections 2.6 - 2.9.
Students will be given the overall vocabulary for Unit 2. This vocabulary set covers computing systems and networking terms. Students should write the definitions in their own words.

Activity 2.5.1 (Budget 30 minutes)
Students can find the definitions for these words in textbooks or online. Good online resources are:
Once students have defined the terms, it is important to review the terminology throughout the instructional lessons when the concepts are being demonstrated. A good strategy is to have the daily vocab terms written on the board. This helps ensure that the demonstrations cover the important concepts and makes sure that all vocab terms are eventually covered in class.
Once the class has participated in a lesson, have the students go back to their handwritten vocabulary list. Do they need to add any details or examples to the definition?
Vocabulary review ideas
Write a definition in your own words as a ticket out the door
Have students write assessment questions for vocab terms (multiple choice, fill in the blank, matching, etc.)
