Electronic computer chips made of tiny silicon wafers now regularly contain millions of electronic switches. Unfortunately, electronic switches that are this small cannot withstand intense radiation. Micro-Mechanics plans to produce a chip that:

Micro-Mechanics plans to produce a chip that:

Only uses microscopic mechanical switches. Therefore it will be invulnerable to radiation damage.

Explanation:

Micro-mechanics plans to produce a chip that, because it uses only microscopic mechanical switches, will be invulnerable to radiation damage. The switches will, however, be slower than electronic switches and the chip will contain only 12,000 switches.

i'm so sorry that's not a question and this isn't an answer
