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.
