Study Notes
Moore's Law
- Gordon Moore observed that the number of components on microprocessors doubled annually (initially).
- Later, the doubling rate was revised to every two years.
- Variations of Moore's Law include that microprocessor power, computing power, and the price of computing all double every 18 months.
Law of Mass Digital Storage
- The amount of digital information doubles annually.
- The cost of storing digital information decreases exponentially (approximately 100% per year).
- Storage capacity on magnetic media roughly doubled every 15 months from 1950 to the present.
Metcalfe's Law
- The value of a network grows exponentially with the number of members.
- Network value increases as the number of members grows linearly, creating increasing returns.
Operating System Platforms
- Microsoft Windows Server, Unix, and Linux are major corporate server operating systems.
- Windows Server caters to Windows-based infrastructures, while Unix & Linux are more scalable, reliable, and affordable.
- IBM, HP, and Oracle-Sun provide variations of Unix.
- Chrome OS (Google) is a cloud-based operating system.
- Android (Google) is a popular mobile OS.
- iOS (Apple) is another prominent mobile platform.
Cloud Computing Characteristics
- On-demand self-service: Users access resources independently.
- Ubiquitous network access: Access through various devices and networks.
- Location-independent resource pooling: Resources are shared and dynamically allocated.
- Rapid elasticity: Resources can be scaled quickly up or down.
- Measured service: Charges are based on resource usage.
Internet Platforms
- Internet platforms include hardware, software, and management services.
- Web hosting services enable website storage.
- Server size and power, along with software tools, have reduced the need for numerous servers.
- IBM, Dell, Oracle, and HP are major players in the internet hardware server market (with declining prices).
Challenges of Managing IT Infrastructure
- Scaling infrastructure to accommodate growth or downsizing.
- Adapting to new applications and varying business needs.
- Implementing Mobile Device Management (MDM) to secure mobile devices.
- Cloud vendor contracts ensuring service availability and security.
- Deciding on centralized or departmental IT control, including cost-sharing.
- Balancing investment to avoid waste or underperformance.
- Choosing between renting and owning IT assets.
- Considering cloud solutions for flexibility and cost-effectiveness (with security precautions).
Green Computing
- Practices and technologies to minimize environmental impact during computer lifecycle.
- Reduced power consumption from data centers and equipment reduces environmental impact and operating costs.
- Energy-efficient equipment, virtualization, and other saving strategies are being used.
Quantum Computing
- Uses quantum physics principles for data representation and operations.
- Handles 0, 1 and both simultaneously.
- Enormous processing power enables solving complex scientific and business problems.
- IBM offers quantum computing through its Cloud, and Google, Alphabet, Microsoft, Intel, and NASA are involved in development.
