Study Notes
Computing: A Historical Perspective
- Charles Babbage built the first mechanical computer in the 1820s.
- ENIAC (Electronic Numerical Integrator and Computer) was the first programmable, general-purpose computer.
- ENIAC was used by the US Army during WWII to calculate firing tables, optimizing gun operations.
- Operating Systems (OS) are the "brain" of a computer, managing all components based on user input.
- Unix, developed by AT&T in the 1970s, is a significant operating system.
- IBM introduced the personal computer (PC) in 1981, revolutionizing computing by making it affordable for personal use.
- Douglas Engelbart's "Mother of All Demos" showcased key personal networked computer technologies, including networking, graphical user interfaces, and video conferencing.
- Local Area Networks (LANs) connect computers within a single building.
- Wide Area Networks (WANs) connect multiple LANs across large geographic areas.
- Ada Lovelace is often regarded as the first programmer in history.
- Unix and its variants have widespread adoption due to their powerful capabilities and low to no associated cost.
