Study Notes

Internet Connectivity and Historical Background

Paul Otlet and Vannevar Bush developed mechanized and searchable storage systems for books and media in the 1930s.
Joseph Carl Robnett Licklider popularized the concept of intergalactic computer networking in the 1960s.
Packet switching technology emerged, leading to the creation of ARPANET, the internet's prototype, on October 29, 1969.

Cloud Computing

Cloud computing allows storage and access to data over the Internet rather than local hard drives.
Services include:
- Infrastructure as a Service (IaaS): Organizations maintain control of infrastructure with system administrators managing components.
- Platform as a Service (PaaS): Provides tools for application development and deployment.
- Software as a Service (SaaS): Users don't manage software/hardware updates, with software hosted in the cloud.
Cloud infrastructure components utilize transistors, offering greater reliability and speed than earlier technologies.

Generational Evolution of Computers

First Generation (1940s-1950s): Utilized vacuum tubes, bulky, and generated heat. Examples: UNIVAC, ENIAC.
Second Generation (circa 1960s): Introduction of transistors, smaller and more efficient, but complex with maintenance challenges.
Third Generation: Integrated Circuits (ICs) emerged, providing powerful computing while occupying less space.
Fourth Generation: Microprocessors developed, incorporating thousands of ICs onto a single silicon chip, facilitating network connections.
Fifth Generation: Focus on Artificial Intelligence, including voice recognition and natural language processing capabilities.

Information Technology Fundamentals

Data refers to raw, unprocessed facts, while information is processed data that has meaning.
Information Technology comprises systems that capture, process, exchange, store, and present information using electromagnetic energy.

Characteristics of Information Society

Information as an economic resource fosters empowerment and contributes to the development of the information sector.
The cycle of information includes creators, products, distribution, disseminators, and users.

Mobile Technology and Communication Networks

Mobile technology enables portable, two-way communication and includes various generations of cellular networks:
- 1G: Voice-only analogue service.
- 2G: Introduced text messaging (SMS) and multimedia messaging (MMS).
- 3G: Broader data capabilities, including video calls and mobile internet.
- 4G: Significant speed improvements, 500 times faster than 3G.
- 5G: Further advancements in speed and connectivity.

The Digital Divide

The digital divide highlights class-based disparities in access to technology, with higher-income individuals enjoying greater technological advantages.

Machine Learning Algorithms

Various algorithms like Linear Regression, Decision Tree, and Neural Networks generate outputs based on input values.
Feature selection and association identify relationships between variables in databases.

Ubiquitous Computing

Ubiquitous computing aims to integrate computing into everyday environments, allowing interaction with devices at any time and place.
Mark Weiser, a key figure in the field, coined the term "Ubiquitous Computing" in 1988.

Key Influencers

Manuel Castells, known for "The Rise of the Network Society," highlights the transformative impact of the Internet in modern communication and information dissemination.
