| Question | Answer |
| Computer | a fast electronic device that accepts INPUT information, Processes it according to a PROGRAM, and produces the resultant OUTPUT information |
| Instrumentalism | Technology can be used and is only a tool (it is neutral) It's not about technology itself, its about how you use it |
| Techological Determinism | Technology is this autonomous force that is unstoppable |
| Media Ecology | the study of media as environment (the media affects us just like our natural environment does, maybe even more) |
| Marshall McLuhan's 4 Laws of Media Effects | 1. What does the media enhance? 2. What does the media make obsolete (no longer needed)? 3. What does the media bring back from the past that used to be obsolesced? 4. What does the media flip into when pushed to the extreme? |
| Who Invented Javascript Programming? | Brendan Eich 1995 |
| What should all Javascript statements end with? | ; |
| In Javascript, when is the escape character used? | before an apostrophe so as to not let the computer think that that is the end quote (escape character - \) |
| Attribute for when the mouse goes over an image | onmouseover |
| Attribute when a mouse is clicked | onclick |
| name of of the computing issues related to robots | robots take care of the weaker members of society. Robots who do nat have emotions. We ourselves lose the ability to care for others and others lose the feeling of human companionship |
| TRUE/FALSE "Put the right kind of software into a computer, and it will do whatever you want it to. There may be limits on what you can do with the machines themselves, but there are no limits on what you can do with software." | FALSE |
| TRUE/FALSE For any given problem, there is only one algorithm | FALSE |
| TRUE/FALSE The parseFloat function in JavaScript takes a numeric input and returns the corresponding string value | FALSE |
| TRUE/FALSE Source code refers to the collection of computer instructions written in binary | FALSE |
| TRUE/FALSE A translator (or compiler) provides real-time translation | FALSE |
| Algorithm | step-by-step instructions for accomplishing a given task |
| This is a binary language that runs directly on the hardware of a particular machine | Machine Language |
| What is made freely available and may be redistributed and modified in the case of open source software? | Source Code |
| Father of the Computer | Charles Babbage -difference engine: mechanical calculator - analytical engine: general purpose programmable computer |
| Transmission Control Protocol (TCP) | controls method which messages are broken down into packets and reassembled at their final destination |
| Internet Protocol (IP) | labelling the packets for delivery and controlling packet's paths |
| Distributed network | Alternate routes for messages |
| Packet-switching | breaking a message into small pieces, sent independently (helps with band width and preventing corruption) |
| Generation 0 | Mechanical Charles Babbage Ada Lovelace (first programmer) |
| Generation 1 | Vacuum Tubes control electric current through a vacuum in a sealed container (perform calculation much quicker) ENIAC: large scale electronic digital computer Alan Turing ELIZA: simulated psychotheropist |
| Generation 2 | Transistors smaller, cheaper, reliable, energy efficient Compiler Grace Hopper |
| Compiler who invented? | a program that translates English language instructions into the language of the Computer by Grace Hopper |
| Generation 3 | Integrated Circuit (IC) enabled numerous transistors to be manufactured on a single chip (smaller, faster, less expensive) |
| Generation 4 | VSLI (Very Large Scale Integration) millions of transistors on a single chip |
| First Personal Computer | Altair 8800 |
| Generation 5 | Parallel Processigna and Networking PP: using multiple processors in a single computer to share computational load Networking: Computers are no longer stand-alone, they are interconnected |
| Ada Lovelace | first programmer |
| Design Norms | Cultural Appropriateness Transparency Stewardship Aesthetic Norms Justice Caring Trust |
| Phishing Attacks | way of attempting to acquire sensitive information by masquerading as a trustworthy site |
| Informationism | faith in the collection and dissemination of information as a route to social progress and personal happiness |
| parseFloat | converting strings into values |
| Difference b/w HMTL and JavaScript | HTML is a static webpage JavaScript creates dynamic webpages |
| Who Developed JavaScript? | Brendan Eich 1995 |
| Event Handlers | listens for an event and responds by running code |
| String | sequence of characters enclosed in quotes |
| Boolean | meaning a true or false statement |
| sequencial search | general purpose but relatively slow start at the beginning and continue through |
| binary search | restricted use but fast continually cutting the desired search list in half until item is found. Only applicable if list is ordered |
| machine language | instructions that correspond directly to the hardware operations of a particular machine |
| assembly language | evolved from machine languages and substituted words for binary code |
| high-level language | allows one to write code closer to the way humans think |
| source code | the collection of computer instructions written in a computer language |
| Program Translation: Interpretation | used to provide a real-time translation the interpreter hears a phrase, translates and immediately speaks the translation (JavaScript) |
| Program Translation: Translator (Compiler) | Translates the entire speech off-line makes copy of speech, returns when the entire speech is translated Ad: once translated it can be read over and over very quickly Dis: must wait for entire speech to be translated (Commercial Software) |
| Parity Bits | find row or colomn that doesn't have an even number of 1s |
| von Neumann Architecture | virtually all modern computers have the same underlying structure |
| Central Processing Unit (CPU) | carries out the instructions to process information acts as the brain of the computer |
| ALU (Arithmetic Logic Unit) | Circuitry that performs the actual operations on data (addition, subtraction etc) |
| Registers | memory locations built into the CPU (to provide fast access) |
| Bus | the transfer of data between registers and main memory occurs across a collection of wires called a bus |
| Control Unit (CU) | circuitry in charge of fetching data and instruction from main memory, as well as controlling the flow of data between registers and the ALU |
