- Transistors replaced vacuum tubes in computer designs in the 1950s.
- The MOSFET was invented in 1959 and led to the microcomputer revolution.
- The integrated circuit (IC) was invented by Jack Kilby and Robert Noyce.
- Noyce's IC was the first true monolithic IC chip.
- MOS IC technology enabled the integration of over 10,000 transistors on a single chip.
- The Intel 4004 was the first single-chip microprocessor.
- System on a Chip (SoCs) are complete computers on a microchip.
- Computers have advanced enormously since ENIAC in 1945.
- Mobile computers were heavy and ran from mains power.
- The first laptops removed the need for mains power by incorporating batteries.
- Portable computers grew in popularity in the 2000s.
- SoCs, complete computers on a microchip, power smartphones and tablets.
- Computers can be classified by architecture, size, form-factor, and purpose.
- Hardware covers all tangible physical parts of a computer.
- A general-purpose computer has four main components: ALU, control unit, memory, and I/O devices.
- The CPU is composed of the control unit, ALU, and registers.
- Modern computers have billions or even trillions of bytes of memory.
