First appeared in the early 1900s, then took off in the 1980s and peaked in 2000s
Media
One of the means or channels of general communication, information, or entertainment in society as newspapers, radio, or television
Drawback of human senses
Only input
Drawback of gestures
Must be present, much have meaning
Innovation and drawback of pointing
Beyond the self but must be present

Standardize and sequence
Innovation of ideograms
Abstraction!
Drawback of logographic writing
Doesn’t scale well
What is English writing?
Alphabetic/phonographic writing
Telecommunication
communication at/across a distance
Drawback of courier/mail
Letters lost/intercepted, must trust messenger, knowledge of where to deliver the message
First form of mass communication
Newspaper
What did the printing press lead to?
Mass media
When did the telegraph first come about?
Early 1800s
What was the first form of electronic communication?
Telegraph
What was the innovation of the telegraph?
Speed
Metcalfe’s Law
Value of telecommunication network is proportional to square of the number of connected users (exponentially)
Disruptive technologies
Far worse than existing but superior in one key vector; disrupting what’s established
Computers
The ability to perfectly reproduce information ad infinitum at a cost over time has become asymptotically close to zero and the ability to store and process information at a scale and speed beyond human ability
Bit
Binary digit; 0 or 1
Byte
8 bits; can store one letter
Hard disk drive
Spinning hard drive
Solid state drive
integrated circuits to store data electronically
Kilobyte –>
Megabyte –> Gigabyte –> Terabyte
ASCII
American Standard Code for Information Interchange
CPU
Central Processing Unit- Brain of the computer/clock; electronic circuitry within a computer that carries out the instructions of a computer program
What is CPU speed measured in?
Gigahertz
What is CPU speed limited by?
Heat
GPU
Graphics Processing Unit; Parallel to handle graphics
System on a chip
All components of a computer on a single chip
Random Access memory
Working memory; only stores while device is on
Pixel
Picture element
Cathode Ray Tube
Electron gun to display images
Liquid Crystal Display
Flat panel display using light modulating properties of liquid crystals
Light emitting diode
Semiconductor light source
Plasma Display
Uses electronically charged ionized gases
Organic Light Emitting Diode
Organic compound emitting light
HDMI
High definition multimedia interface; audio/video transfer
3 rules of hardware
Over time computer hardware becomes: smaller, mechanically simpler, faster/more efficient
Moore’s Law
Tech doubles every 2 years
Code
Set of symbols interpreted by a computer or piece of software
Algorithm
Solves a problem
Programming language
System for encoding, naming, and organizing algorithms for reuse and application
Standard library
Set of premade software you can reuse and reapply
Object-oriented programming
Filing system for code; like labeled boxes full of specific data/methods
Database
Library where data is stored and can be called from
How does code work?
Written in a language, run letter by letter through a compiler, making instructions for the computer to execute
Integrated Development Environment (IDE)
Software suite that consolidates basic tools developers need to write and test software; contains code editor, compiler/interpretor, debugger accessible through a single graphical user interface
Software development kit
Set of software tools that allows the creation of applications
Where did networks originate?
originated in military–>academic institutions–>tech corporations–>everywhere
Internet takeover
1993: 1%, 2000: 51%, 2007: 97%
ARPA/DARPA
(Defense) Advanced Research Projects Agency; US agency responsible for developing emerging technology for use in military
ARPANET
Network that became the basis for the Internet
