Text: Fluency with Information Technology, Snyder, 3-rd Ed

-----
Ch 1: Terminology of IT
-----

- component/monolithic computers
- bitmapped monitors
- pixels, colors (more in the lecture on multimedia)
- motherboard, RAM, Hard disc,
- saving data
- algorithms/programs
- executing a program
- booting
- WYSIWYG

Ideas: abstraction, generalization in IT
       understanding the idea of "factor of improvement"


-----
Ch 2: Human Computer Interaction
-----

- metaphors + examples
- principle "Form follows function" + examples
- searching text (up to p. 52); you do not need to worry about
  "editing text using substitution".


-----
Ch 3: Networks, Internet
-----

- communication types (broadcast / peer to peer)
- circuit/packet switched nets
- types of network connections, ex: wired and wireless, how data are
  encoded for transmission


-----
Ch 8: Data representation
-----

- digitizing discrete information
- encoding, how we can assign symbols to data, and what principle
  should be observed (we need to interpret the info back from the
  representation, so we need a sufficient number of symbols)
- types of data, numeric and text + their encoding
- what are bits and bytes
- you need to understand that bits can represent many things, and it
  is up to "us" to interpret them appropriately.


-----
Ch 9: Hardware 
-----

- main components of a computer (ALU, memory, processor, I/O) +
  + roles 
- what is decoding an instruction?
- memory, memory location, addresses, and values
- program counter
- fetch execute cycle of a processor, main steps!
- system clock 
- what is an operating system + role
- program vs algorithm, what it means to program a computer
- transistor, role and how it works (main idea); what is the field effect
- what are integrated circuits. What does "integrated" refer to?
- what is "booting"
- what is a file system



-----
Ch 14: Spreadsheets & Ch. 15 up to page 423.
-----

- what are spreadsheets
- cells and types of data (value, text, formulae)
- what is a date/time? 
- difference between data type and data format (format = how data is
  displayed) 
- operations on dates and time (+/-,...)
- absolute and relative references
- fill handle
- basic operations with data (sorting, if function, max and sum, etc);
  check the examples and understand how data is manipulated but you
  need not study the examples in depth.
- importing/exporting spreadsheet data, what is does and goal (to make
  available to other applications by representing data with text)
- understandf the IF function (this is explained in Chapter 15)


-----
Ch 5: Searching
-----

- types of searches
- types of resources (subject trees, clearinghouses, (meta) search engines...)
- hierarchy of information
   * tree structure
   * difference between search on page (ctrl-F in browser) vs search with a general
     search engine
- search engines
   * parts
   * indexing
   * ranking
   * how are queries given, boolean queries
- assessing accuracy
   * what is a "whois search", where it is useful
   * quality of information of different types of resources (ex
     clearinghouses vs subject trees vs wikipedia vs Encyclopedia
     Britannica) 


-----
Ch 4: HTML
-----

- structured documents, examples of parts and structure (eg
  formatting) 
- what are tags and their role
- anchors
- page links and URL, absolute vs relative references


-----
Ch 10: Programming, Logo
-----

(text only up to page 184 in 2nd edition, or up to p. 264 in 3rd ed)

- variables
- procedures, procedure parameters or arguments
- abstraction 
- context
- understand how programs are specified using simple logo commands
  * write code to draw simple figures (eg letters like A T F H ...)
  * draw the outcome of Logo programs


-----
Ch 11: Multimedia
-----

- representation of colour (RGB, other representations possible)
- how we perceive colour (psychology and physiology)
- digitizing a continuous value (colour intensity)
- representation of images
- lossy vs lossless compression
- representation of sound, sample, rate, bits per sample
- what is a psychoacoustic model?
- what is the "frequency domain"?


-----
Ch 12: social implications of IT
-----

- malware and classification (virus, worm, trojan)
- characteristics of malware
- what does "infected computer" mean?
- what do antivirus software do?
- good vs weak passwords
- what is copyright?
- what is a software license, why it is there?
