Takeaways

  • 🕒 The history of computing began in the 1800s with the development of early computing machines.
  • 🛠️ Konrad Zuse created the first programmable computer, the Z1, in the 1930s, and later the Z3, considered the world's oldest digital computer.
  • 💡 The Z3 was destroyed during WWII, but Zuse later launched the Z4, the world's first commercial digital computer in 1950.
  • 🔍 J.V. Atanasoff and Clifford Berry designed the Atanasoff-Berry Computer in 1941, the first to store data in memory.
  • 🔐 The Harvard Mark-1 / Colossus, inaugurated in 1944, played a significant role in WWII by breaking the Lorenz ciphers.
  • 🚀 ENIAC, created by John Mauchly and Presper Eckert in 1945, was used for ballistic analysis and was a massive machine with 6000 switches and 18,000 vacuum tubes.
  • 📈 Transistors replaced vacuum tubes, leading to the creation of the Manchester TC, the first prototype computer with transistors, in 1953.
  • 💻 Grace Hopper developed COBOL, the first computer language, and IBM introduced its first computer, the IBM 701, around the same time.
  • 🌐 The 1960s saw IBM's 7000 series of mainframe computers, which included the Stretch model, contributing to the development of the IBM 360 series.
  • 🏷️ The 1965 launch of the Program 101 marked the first desktop computer sold to the general public.
  • 📦 Intel's 1103 in 1970 was the first DRAM chip, and IBM invented the floppy disk in 1971 for data sharing between computers.
  • 💼 The Altair 8800 in 1975, using BASIC language, is credited with popularizing the term 'personal computer'.
  • 🍎 Apple's entry in 1976 with the Apple I and subsequent Apple II in 1977 marked significant milestones in personal computing.
  • 💾 The IBM PC in 1981, based on the Intel 8088 microprocessor and MS-DOS, revolutionized the development of personal computers.
  • 🖥️ Apple Lisa in 1983 introduced the first graphical user interface in a personal computer.
  • 🖱️ The Macintosh in 1984 was the first successful computer with a graphical user interface and a mouse.
  • 🛠️ Michael Dell founded PC's Limited in 1984, developing the Turbo PC and becoming a leading computer developer in the 1990s.
  • 📦 The IBM Personal System 2 in 1987 was the first IBM system with the Intel 80386 chip and OS2, introducing the mouse to IBM computers.
  • 🌈 Apple's iMac G3 in 1998 featured a clear, customizable case and came with advanced specifications for its time.
  • 🔌 The Apple G5 in 2003 was the first true 64-bit personal computer with an anodized aluminum case.
  • 🌐 The 1990s saw the widespread use of personal computers with the advent of the Internet, leading to a growing market for computer components.
  • 📚 The evolution of computers has been drastic, from room-sized machines to small, high-performance PCs like the Apple Mac mini.

Q & A

  • What was the significance of the Z1 computer created by Konrad Zuse?
