Privacy • Assume digital data lasts forever • "Do I want my employer in 10 years to see this? " Introduction to Computer Science © 2015 Project Lead The Way, Inc.

Personal, identifiable information • Your name • Address • School name • E-mail address • Telephone number • Pictures of yourself • Birthday Introduction to Computer Science © 2015 Project Lead The Way, Inc.

A secure private channel • Check for the "S" in HTTPS. • Check for a domain name you trust in the URL = Uniform Resource Locator, the website address you type into the browser. • Even a secure private “https: //” channel with an entity you trust has limited privacy and you should assume there will be a permanent record. Introduction to Computer Science © 2015 Project Lead The Way, Inc.

A secure private channel • Domain names control their subdomains. Examples: – bad. amazon. com belongs to amazon. com (trusted) – amazon. bad. com belongs to bad. com (no relation to Amazon) Introduction to Computer Science © 2015 Project Lead The Way, Inc.

Understanding Domain Names Internet Assigned Numbers Authority (IANA) controls top-level domains such as. com, . org, and. edu. Example Top Level “Root” Domains Top Level Domain Type Owner . ie country code University College Dublin, Ireland . jp country code Japan Registry Services Co. , Ltd. . org generic Public Interest Registry, Reston, VA . edu sponsored EDUCAUSE, Louisville, CO . com generic Verisign Global Registry Services Source: Internet Assigned Numbers Authority, IANA. org Introduction to Computer Science © 2015 Project Lead The Way, Inc.

Understanding Domain Names www. si. edu Root: edu airandspace. si. edu Domain: si (Smithsonian) americanhistory. si. edu subdomain: airandspace (Air and Space Museum) subdomain: americanhistory (American History Museum) Domain names such as amazon. com and wikipedia. org must be registered with a Domain Name System (DNS) host. DNS servers provide records that map domain names with their corresponding IP addresses. When a user types in a URL, the browser sends out a DNS query. The DNS returns the IP address for that URL. The web browser uses that IP address to communicate with the web server. Do all of these URLs belong to Google? calendar. google. com Introduction to Computer Science docs. google. com google. docs. com © 2015 Project Lead The Way, Inc.

Digital Citizenship • Use social media to encourage others and build community. "Act as if the world is a giant block party and you are its gracious host. " • Meanness hurts! Best practice is to disengage. Tell a parent, teacher, or other respected person if you're unsure whether a situation warrants attention.

CFAA Computer Fraud & Abuse Act • Do not access computer resources that you do not have permission to access. Introduction to Computer Science © 2015 Project Lead The Way, Inc.

Computational Resources • Bandwidth bits per second in/out of a facility • Data storage nonvolatile for inactive bits RAM for active programs/data • CPU cycles read/receive, calculate, write/send • Electrical energy (grid, battery) Introduction to Computer Science © 2015 Project Lead The Way, Inc.
