http://www.abovetopsecret.com/forum/thread860156/pg1

Okay, we're going to change the format here. Since it's difficult to rely on other blogs to approve your comments, I want you to do your Exam Preparation here on my blog. Post all of your responses as comments and I will read and approve them as they come in.

ITGS Study Guide

All of this is taken from your ITGS Textbook (come to me if you've lost your digital copy).

Required reading!

SL/HL: 11-29. 291-373, Chapter 3 Overviews for each section (ie. 3.1, 3.2, 3.3, 3.4, 3.5...)

SL: 253-258

HL: 253-287

Also, you must read AT LEAST the overview of each section in Chapter 3 (ie. 29, 62, 94, 124, 163, etc)... I say AT LEAST, but it would be a good idea to read as much as you can from each section.

 

Specific terms and concepts you should know (these will be updated throughout the week):

File formats (audio/video/documents/images)
Biometrics
Databases (key fields, relationships, Field Types, etc)
Privacy (How do websites protect users? What policies do they create?)
Information transferring (real-time vs store and forward. KB/s vs Kb/s)
Satellites
Electronic vs manual data collection
What do agencies do with information they collect? (Businesses, governments, hospitals, environmental groups)
Facebook/Twitter/Instagram (privacy? Who own images uploaded?)
School policies (what digital policies should schools enforce?)
PRODUCT DEVELOPMENT LIFE CYCLE (learn it!) Feasibility Studies, Milestones, Initiation
Different types of networks (peer-to-peer, server-client, etc)
ISPs (what do they do?)
Traffic systems (using digital models for prediction, collecting information, who uses it? SMS alerts?)

ITGS Past Papers

As we discussed on Monday, your job over the next couple of classes is to choose 3 exams from the folder I've shared with you. Complete all questions to the best of your ability and we'll discuss them when I come back.

Here is the link for your past papers.

Remember that all classes will be held in Layang2 for this week (just makes it easier for whichever substitute teacher will be coming).
