Personal computer
Silicon Graphics
Silicon Graphics built the first practical hardware-accelerated 3D graphics systems. Its Geometry Engine — designed at Stanford under ARPA — delivered ~6 million geometry operations per second. It pioneered scalable cc-NUMA architectures in the mid-1990s. But its reliance on proprietary MIPS and failed transitions to Itanium and Xeon eroded its position as PC graphics commoditised. It filed for bankruptcy in 2009.

LED display
The LED display is not Holonyak’s invention — it is HP’s. Holonyak’s 1962 GaAsP LED enabled it. HP’s 1969 Model 5082-7000 was the first intelligent, IC-integrated numeric display — fast, solid-state, low-power, and monochromatic. It displaced Nixie tubes but could not render text, graphics, or colour. Later all-LED flat panels remained monochrome and experimental.

Flash memory
Flash memory is a block-erasable, non-volatile semiconductor memory invented by Fujio Masuoka at Toshiba in 1980. It builds on EEPROM but replaces byte-wise erasure with faster block-wise erasure — enabled by floating-gate transistor design. The name 'flash' was coined by colleague Shōji Ariizumi to reflect that speed. Masuoka and colleagues presented NOR flash in 1984 and NAND flash at the 1987 IEDM. Toshiba began marketing flash memory and commercially launched NAND flash — both in 1987. The first published implementation held only 8192 bytes but became the basis for larger-capacity versions. Flash does not support byte-level writes or in-place updates; erasure is all-or-nothing per block. It cannot replace RAM or true EEPROM where fine-grained modification is required. Flash changed how portable devices store firmware and user data, enabling compact, shock-resistant, low-power storage that scales without moving parts — a prerequisite for digital cameras, USB drives, SSDs and smartphones.

Thermistor
The thermistor is a semiconductor resistor whose resistance changes strongly with temperature. Michael Faraday discovered its NTC behaviour in silver sulfide in 1833. Commercial production did not begin until the 1930s due to manufacturing difficulty and limited applications. Samuel Ruben invented a commercially viable version in 1930.
