The microchip was invented by Robert Noyce and Jack Kilby. A microchip is built by layers of a semiconductor material of silicon or germanium
1958 by Jack Kilby working at Texas Instruments. It was made of germanium (not silicon), 7/16-by-1/16-inches in size a 1 transistor sine wave oscillator.
Because - when Colossus was built (in 1943), microchips had yet to be invented ! Microchips replaced valves and transistors in newer computers.
You would say the latter. eigh percent of microchips ARE defective
t.v.'s,Nintendo's Nintendo d.s.s,wii's,computers,laptops,phones,cell phones,microchips,the newer style cars,hydro power cars.
NO !
no they are not

Microchips are used today as implants in living bodies to aid in tracking and identification.

Microchips when handled without the greatest degree of security can breach the confidentiality of medical records and any other records. Microchips store so much information that interception of them can have devastating consequences.
Most sand is composed of quartz - silicon dioxide. The element silicon is used to make microchips.
