Midterm Flashcards
Media
one of the means or channels of general communication, information, or entertainment in society, as newspapers, radio, or television.
New Media
Emerging Digital media
How we got to now:
Human senses–>gesture–>signs–>speech–>cave paintings–>pictogram–>ideogram–>logographic writing–>phonographic writing
Human senses and limitation
Foundation of experience; limitation: only input
Gestures and limitation
Produce signals; limitation: real-time, physical objects
Signs and limitation
Semiotics; abstract/not just about what is present; limitation: real-time
Speech and limitation
More variety, easier, distance; limitation: real-time
Cave painting and limitation
Permanence! Limitation: clarity, non-abstract things
Pictogram and limitation
Standardized, sequence; can be repeated; limitation: clarity
Ideogram and limitation
Abstraction; limitation: clarity
Logoraphic writing and limitation
(Ie, Chinese); grammar, standardization; limitation: can’t keep adding words
Phonographic writing
Infinite!
Papyrus:
Solved problem of durability/permanence/portability
Greek semaphore
Needed infrastructure; limit to line of sight and weather
Couriers
letters lost, trust messenger, must know where to go
Early newspapers
First mass communication
Printing Press and Movable Type
Now have speed and copies
Typewriter
Available to individuals
Telegraph
1st electronic communication; real time transmission
Innovations by Digital revolution
Ability to perfectly reproduce info ad infinitum at a cost over time asymptotically close to zero; ability to store and process info at a scale beyond human ability
ASCII
American Standard Code for Information Interchange
HDD
Hard disk drive- spinning
SSD
Solid state drive- uses integrated circuits to store data electrically
Byte
8 bits
CPU
Central Processing Unit; brain/clock (linear)
Why are CPUs multicore?
Faster–>more heat and also getting smaller and smaller; lowers heat and lowers power consumption
GPU
Graphics Processing Unit; parallel
SoC
System on a Chip (Smartphones)
RAM
Random Access memory (working memory); nothing is permanent
Pixel
Picture element
Retina Display
Apple marketing term; number of pixels packed in
CRT
Crystal Ray Tube; emits electrons into pixel grid
LCD
Liquid crystal display; electric current over crystals and LED backlight
Plasma Display
Ionized gases create bright light
OLED
Organic light emitting diode; individual light turned on and off at each spot (Apple watch)
USB 3
Non-reversible; too big
USB C
Smaller; will take over
Thunderbolt
Apple display port
Lightning
First reversible cable; iOS
HDMI
High Def Multimedia Interface
VGA
Video Graphics Adaptor
ARPA
Advanced Research Projects Agency
ARPANET
Early packet switching network; first to implement TCP/IP
Robert Metcalf
Ethernet at Xerox PARC 1973
Minitel
France 1978
Tim Berners Lee
Invented World Wide Web 1991 on a NEXT computer at CERN
Internet takeover
1% in 1993, 51% in 2000, 97% in 2007
Joseph Licklider
Invented Intergalactic Computer Network
1982
ARPANet networking standard publicly available
1985
First .com address
Network Packets
circuit switching: single uninterrupted wire connection; packet switching: packages, increases bandwidth and number of computers
IP
Internet protocol; (172.194.121.32=google.com)
DNS
Domain name system- layer on top of IP
Internet
Any set of network computers that communicate over Internet Protocol
Web
Layer on top of internet with publicly available addresses and docs linked to other docs
Router
Distributes internet to computers
Modem
Interprets from internet service provider
URL
Uniform Resource Locator- way we specify where on a site we want to go
TLD
top level domain (.gov, .com)
web server
computer mozilla is running on
HTTP
Hypertext transfer protocol- how is website being communicated from one to the other one
Ethernet
Main wired interface for connecting computers to local area networks
Wifi
Main wireless interface for connecting computers to local area networks
Dial-Up Internet
Over existing phone lines
DSl
Digital subscriber line; copper like dial up but for data only
Fiber
Fiberoptic cables; sends pulses of light
When did the term new media become big?
the 1990s
First permanent form of communication
Cave painting
