AP CSP Computer Science Principles

Purpose The intended goal or objective of the innovation
Function How the innovation works (consumes/produces data)
Effect

An impact, result, outcome of the innovation

- Explain and put into context
- Relate to economy, society, or culture
- Connect to a group or individual

Feature An "extra" attribute or aspect of an innovation
Culture A group of people: example - football players, students with asthma
Economy A group of people with similar economic interests, or whose jobs or industry are similar (Netflix put Blockbuster out of business)
Society Be specific - whose society? which society?
Data Think of what types of files are being used, saved, sent - what is the input and output? Not the sensors or transmission method (cameras, cables, chip readers, etc)
Storage How big are the files? how will everything be stored? What problems are there?
Security What might happen if data is accessed? Hacking can be mentioned here.
Privacy What can someone do with the data if they are able to get it?

 

Getting Started TO DO List:

- review task directions & scoring rubric
- gather resources for your information and artifact (save the URL's)
- identify purpose and function
- identify a beneficial effect - and connect to society, culture or economy
- identify a harmful effect - and connect to society, culture or economy
- explain the types of data used, and input/process/output
- identify a data storage , security, or privacy concern

- then begin the actual writing responses

Week 15: Dec 9 - Dec 13


Week 14: Dec 2 - Dec 6

Vocabulary

  • tracing - the process of following the code through each step
  • transmission control protocol (TCP) - provides reliable, ordered, and error-checked delivery of a stream of packets on the internet. TCP is tightly linked with IP and usually seen as TCP/IP in writing
  • internet - a connection of devices connected to each other via hardware, including routers, servers, and other devices, each of which is given an IP Address and must follow protocols
  • Internet (The Internet) - the worldwide connection of devices to each other (internet on a global scale); The Internet refers to the physical network of computers and the way in which they are all connected. The World Wide Web is how most people access the information stored on the Internet.
  • Internet Protocol (IP) - the way devices communicate with each other
  • Internet Protocol (IP) addresses: a unique string of numbers separated by periods that identifies each computer/device using the Internet Protocol to communicate over a network.
    - IPV4 was a 32-bit address (4 bytes) and allows for up to 4.3 billion addresses
    - newer IPV6 is 128-bit address (16 bytes) and allows for up to 3.4×1038 =  (340 undecillion addresses)
  • ISP - Internet Service Provider - a company that you pay to provide connection to the internet

 

Week 13: Nov 25 - Nov 27

Vocabulary

  • different paths: Routers respond to traffic on the Internet in real time. The best path at one moment might be backed up a few seconds later. Routers choose the current best path to get the message through
  • distributed denial-of-service (DDoS) - a type of computer attack that uses a number of hosts to overwhelm a server, causing a website to experience a complete system crash
  • domain name syntax - hierarchal definition of what a domain should look like; for example in nbc.com the ',' character marks the location of the type of address this is - to the right is .com so nbc is located on the name server that contains all the 'com' addresses
  • domain name system (DNS): maps internet domain names to the internet protocol network addresses they represent and allows websites to use names, rather than difficult-to-remember IP addresses
  • dropped messages: Poorly formed messages cannot be delivered and so are dropped, just like a letter with a bad address on it
  • ftp - file transfer protocol - the way that files can be transferred from a computer to the internet (often used in website development)
  • HTTP: hypertext transfer protocol (HTTP) is the protocol for data communication for the World Wide Web - it handles file requests for information from servers and delivers results to the client

 

Week 12: Nov 18 - Nov 22

Vocabulary

  • modem - a piece of equipment that allows digital data to be tranmitted over cable or phone lines. Data is tranmitted in waves but stored digitally. This conversion is modulation/demodulation (hence the word modem)
  • packets - Small chunks of information that have been carefully formed from larger chunks of information.
  • internet - a connection of devices connected to each other via hardware, including routers, servers, and other devices, each of which is given an IP Address and must follow protocols
  • router (as part of the larger internet): a computer which receives messages travelling across a network and redirects them towards their intended destinations based on the addressing information included with the message.
  • router (as part of a home network): receives data from the modem and sends it to the connected devices on your home network
  • routing (of packets) - way in which data is sent on a network
  • domain name system (DNS): maps internet domain names to the internet protocol network addresses they represent and allows websites to use names, rather than difficult-to-remember IP addresses
  • Internet (The Internet) - the worldwide connection of devices to each other (internet on a global scale); The Internet refers to the physical network of computers and the way in which they are all connected. The World Wide Web is how most people access the information stored on the Internet.
  • Internet Protocol (IP) - the way devices communicate with each other
  • Internet Protocol (IP) addresses: a unique string of numbers separated by periods that identifies each computer/device using the Internet Protocol to communicate over a network.
    - IPV4 was a 32-bit address and allows for up to 4.3 billion addresses (set of 4 bytes)
    - newer IPV6 is 128-bit address and allows for up to 3.4×1038 =  (340 undecillion addresses) (set of 16 bytes)
  • ISP - Internet Service Provider - a company that you pay to provide connection to the internet
  • ISOC (Internet Society) -  International nonprofit organization that handles Internet standards, education and policy development - Mission: To promote the open development, evolution, and use of the Internet for the benefit of all people throughout the world
  • Internet Standard - evolving "rules" that govern how a device and join and/or communicate on the Internet
