Study Notes
Technology Breakthroughs
- The Second World War and its aftermath saw key advancements in electronics, including the development of the first programmable computer and the transistor.
- These innovations in microelectronics, computers, and telecommunications paved the way for the widespread diffusion of new information technologies in the 1970s.
- The transistor enabled the fast processing of electric impulses in a binary mode, making it possible to code logic and communication between machines.
- Integrated circuits ("chips") are made from millions of transistors.
Microprocessor Revolution
- In 1971, Intel introduced the 4-bit 4004 microprocessor, which brought information-processing power to everyday devices.
- Moore's Law states that the number of transistors in an integrated circuit doubles approximately every two years, leading to a doubling of computing power every 18-24 months.
- This exponential growth in computing power was aided by advancements in parallel processing.
- Miniaturizing and specializing chips at decreasing costs enabled their integration into daily objects, from dishwashers to automobiles.
Networked Microcomputing and Big Data
- In the late 20th and early 21st centuries, the increasing power of microprocessors drove a dramatic expansion of microcomputing power.
- Since the mid-1980s, microcomputers have been interconnected in networks, facilitated by portable computers and, later, mobile phones.
- The combination of cheap storage and increased computing power ushered in the era of Big Data, where massive data sets are analyzed to identify patterns.
- This data can be collected intentionally for specific purposes (e.g., black hole image analysis, brain scan analyses) or as a byproduct of user activity (e.g., online behavior).
Telecommunications Revolution
- The ability to network computers emerged due to major advancements in telecommunication and computer networking technologies during the 1970s.
- These advancements were further propelled by new microelectronic devices and increasing computing capacity.
- Telecommunications were revolutionized by the combination of "node" technologies (electronic switches and routers) and new transmission technologies.
- Advancements in optoelectronics, including fiber optics and laser transmission, significantly increased the capacity of transmission lines.
The Internet and Ubiquitous Communication
- In the 1960s, a call was made to connect computers to create an environment for enhanced computer research.
- The US Department of Defense, via the Advanced Research Projects Agency (ARPA), established the first large computer network in 1969, laying the foundation for the internet.
- Different forms of radio spectrum utilization, coaxial cable, and fiber optics allow for diverse and versatile transmission technologies, enabling ubiquitous communication between mobile users.
- Cellular telephony gained widespread adoption worldwide from the mid-1990s onwards.
- By 2000, the technology for a universal-coverage personal communication device existed; however, technical, legal, and business challenges needed to be addressed before market release.
Commercial Network Infrastructure
- Starting in the late 1980s, commercial providers began building out network infrastructure, leading to the growth of the internet.
