Study Notes

Network Topologies

Star Network: Central node failure can disable the entire network.
Bus Network: Uses a common backbone as a shared communications medium; typically covers large areas.
Mesh Network: Provides redundancy but does not have a central point of failure; more resilient than other topologies.
Ring Network: Each device is connected in sequence; failure of one node can disrupt the entire network.

Wireless Communication

Radio Frequency: Disadvantage includes high susceptibility to interception.
Microwave Transmission: Offers high-speed transmission without the need for cables, though it can't penetrate obstacles.
Infrared Communication: Effective only for short distances, making it less suited for wider applications.
Cellular Communication: Typically utilizes microwave transmission for connectivity.

E-Commerce and E-Government

B2B E-Commerce: Reduces resupply times and cuts costs by connecting business partners through a virtual supply chain.
E-Government: Aims to simplify information sharing among governmental entities, enhancing citizen engagement.

Economic Behavior and Marketing

Bartering During Economic Downturns: Individuals and businesses utilize bartering to obtain goods and services without spending money.
Retargeting in Online Advertising: Recaptures shoppers who abandon carts using targeted ads to encourage completion of purchases.

Local Area Networks (LAN)

LAN Functionality: Facilitates rapid communication among users within an office, enabling tasks like document printing and device sharing.
Backbone Role: Acts as a shared communications medium in a bus network.

Reporting and Data Analysis

Querying Tools: Present data as formatted data, graphs, and charts, enabling users to make their own data requests.
Data Cubes: Allow summarization of numeric facts across multiple dimensions, critical for Online Analytical Processing (OLAP).

Knowledge Management

KM for Innovation: Enhances idea flow among employees and business partners, fostering innovation through collaboration.

Business Intelligence (BI) and Data Science

BI Purpose: Aims to visualize, analyze, and present data for improved decision-making.
Data Scientist Role: Combines business skills, analytics, and data knowledge to deliver improvements; works often in team settings.

Educational Requirements and Skills

Data Scientist Education: Involves mastery of statistics, math, and programming; rigorous training is essential.

Wireless Generations and Communication

Network Types:
- WAN: Covers large geographic regions and supports transborder data flow.
- 5G Technology: Allows very high speeds at frequencies over 24 GHz.

Data Visualization Techniques

Word Cloud: Visual depiction of words based on frequency of occurrence, useful for summarizing content visually.
Reporting Tools: Designed for easy user interaction, allowing non-IT personnel to generate data requests.

Security and Mobile Device Management

Security Policies: Central groups enforce policies using Mobile Device Management (MDM) software to manage mobile devices across networks.
Data Mining Techniques: Association analysis involves forming statistical rules about relationships among data items.

Capturing Knowledge

Tacit Knowledge Capture: Techniques like shadowing and joint problem-solving are commonly employed by organizations to document informal knowledge flows.
