Study Notes
Evolution and History of Information Technology
- Information technology (IT) has been intertwined with human existence, evolving with communication methods throughout history.
- The modern era of IT heavily relies on computers and the internet for various functions: communication, research, work, entertainment, and education.
- Traditional communication and information methods have been largely replaced by digital technologies.
Writing Systems in Early Beginnings (3000 B.C.--1400 A.D.)
- The invention of writing systems, like cuneiform in Mesopotamia and hieroglyphs in Egypt, marked a significant shift from oral traditions to written documentation.
- Cuneiform, created by the Sumerians around 3500 BCE, facilitated the recording of knowledge and paved the way for literature.
- Hieroglyphs, emerging around 5,000 years ago in Egypt, used pictorial symbols to represent words and sounds, indicating early independent development.
Early Computing (1900–1950)
- The concept of a stored-program computer, introduced in 1947 by John von Neumann, fundamentally shaped modern computing architecture.
- Two main types of computers were identified: Fixed Program Computers (specific functions, e.g., calculators) and Stored Program Computers (multi-tasking capabilities).
- Stored program computers consist of three main units:
- Central Processing Unit (CPU): Executes program instructions with components like Control Unit (CU) and Arithmetic Logic Unit (ALU).
- Main Memory Unit: Holds executing program instructions and data.
- Input/Output Devices: Facilitate data input and output operations.
Digital Revolution (1950–2000)
- Mainframe computers, like IBM's System/360, emerged in the 1950s, enabling large-scale data processing.
- The introduction of microprocessors in the 1970s led to personal computers (e.g., Apple II, IBM PC) making technology accessible to homes and small businesses.
- The 1990s marked the expansion of the Internet and the World Wide Web, enhancing communication and information sharing through email and early web browsers.
Key Takeaways from the Digital Revolution
- The digital revolution transitioned society from analog to digital technology, influencing various aspects of daily life.
- It introduced innovations like the Internet, smartphones, and online ecosystems, reshaping work and communication.
- Positive impacts: easier access to information, enhanced global connectivity, job creation, democratized education, and social empowerment.
- Negative impacts: rising cybersecurity risks associated with the digital landscape.
Impact of the Digital Revolution
- Facilitated everyday tasks such as internet banking, online shopping, and remote work.
- Offered instant connectivity regardless of geographical location.
- Enriched communication methods with social media and navigation tools.
Mobile Phone Development
- The mobile phone development timeline began in the late 1960s, evolving from heavy, car-based models to portable devices.
- Motorola DynaTAC 8000x, launched in 1984, was the first truly portable mobile phone, weighing nearly 1 kg and costing £2,480 (approximately £5,573 today).
- Motorola MicroTAC 9800x, launched in 1989, was notable for its flip-open design, compact size, and improved features (e.g., stored contacts).
Notable Nokia Models and Contributions
- Nokia 1011, released in 1993, was the first GSM phone to support SMS text messaging.
- Nokia's models like the 8110 (1996) and 3310 (1999) became cultural icons with customizable features, and popular games like Snake.
- Mobile phones transitioned into fashion accessories among teenagers, highlighted by unique ringtones and designs.
