Study Notes

Moore's Law

Gordon Moore, a Fairchild Semiconductor executive, observed that the number of transistors on a chip doubled annually (initially).
This observation became known as Moore's Law.
Later iterations of the law reduced the rate to a doubling every two years.
Variants often incorrectly state the doubling of microprocessor power or computing power or the halving of price every 18 months.

Law of Mass Digital Storage

The amount of digital information roughly doubles annually.
Storage costs decrease exponentially (e.g., 100% per year).
Storage capacity (megabytes on magnetic media) for a fixed dollar value roughly doubled every 15 months historically.

Metcalfe's Law

Robert Metcalfe, Ethernet inventor, proposed that a network's value grows exponentially with the number of users.
Increased network participation leads to greater returns for all members.
Value growth is exponential compared to the linear growth in user numbers.

Operating System Platforms

Microsoft Windows Server, Unix, and Linux are primary corporate server platforms.
Windows Server is popular within Windows-based infrastructures; Unix/Linux are scalable, reliable, and affordable.
IBM, HP, and Oracle-Sun are major Unix providers.
Microsoft Windows is the dominant PC operating system.
Chrome OS enables cloud-based computing.
Android is the most used mobile operating system.
Apple's iOS is a competitor in the mobile market.
Multitouch technology is becoming common in various devices for user experience improvement.

Cloud Computing Characteristics

On-demand self-service: Users access resources independently.
Ubiquitous network access: Resources are available through network connections (including mobile).
Location-independent resource pooling: Resources are shared, dynamically allocated.
Rapid elasticity: Resources are scalable (up or down).
Measured service: Billing is based on consumed resources.

Internet Platforms

Internet platforms encompass hardware, software, and management services for websites.
Web hosting services provide space for websites on servers.
Server centralization (using fewer, larger servers, and software tools) is an ongoing trend.
IBM, Dell, Oracle, and HP dominate the hardware market.
Microsoft, Oracle-Sun, and independent developers provide software tools.

IT Infrastructure Challenges

Adaptation to platform changes, business growth fluctuations.
Mobile Device Management (MDM) plays a key role in security.
Centralized versus department-based IT control (and cost sharing).
Investment decisions involving renting/owning IT assets, assessing cloud solutions, and operational considerations.

Green Computing (Green IT)

Green Computing aims to minimize the environmental impact of IT equipment.
Factors include equipment energy consumption, data centre design and equipment selection choices.
Practices include energy-efficient equipment, energy-efficient design, and virtualization techniques.

Quantum Computing

Quantum computing leverages quantum physics for processing.
Data units can represent 0, 1, or both simultaneously (superposition).
This allows for significantly faster processing of certain problems compared with classical computers.
IBM, Google, Microsoft, Intel, and NASA are involved in quantum computing development.
