Study Notes
Week 1
- Moore's Law describes the exponential growth of integrated circuits
- Disruptive technology is an innovation that fundamentally changes an industry
- Businesses can future-proof by anticipating technological advancements
Week 2
- Data, information, knowledge, and wisdom are progressively more complex and valuable concepts.
- The DIKW model and DAKIR model represent the progression of data to wisdom
- Knowledge types include explicit (easily documented) and tacit (personal and hard to transfer).
Week 3
- The DBMS manages a database's data.
- A hierarchy structure is a database organized logically in tables, records, and fields
- A management information system (MIS) is a system that collects, analyzes and presents information.
- Various information systems exist with differing functions for businesses
- Information management involves methods for utilizing data for business
- A CPU performs operations; speed is measured by clock cycles per second, measured in Hertz (Hz)
- RAM, ROM, and secondary storage are different types of computer memory differing in speed and persistence.
- Embedded systems are software for particular devices and appliances
- Real-world examples of embedded systems include: toasters, automobiles, etc.
Week 4
- Levels of abstraction in software represent different views of its design, from high-level conceptual to low-level detailed.
- Differences exist between programming through language compilation and interpretation.
- Application software performs particular tasks; system software operates computers under control of application software
- Examples of the former include: Microsoft Word; examples of the latter include: operating systems (macOS, Windows).
- Open-source software gives users access to code. Advantages include modification and reduced cost. Disadvantages include technical support.
Week 6
- Domain names function as internet addresses.
- ISPs provide internet access.
- Cloud computing models include:
- PaaS (Platform as a service)
- SaaS (Software as a service)
