Shear zone. A shear zone is a very important structural discontinuity surface in the Earth's crust and upper mantle. It forms as a response to inhomogeneous deformation partitioning strain into planar or curviplanar high-strain zones. Intervening (crustal) blocks stay relatively unaffected by the deformation.
A computer-on-a-chip combines the microprocessor core (CPU), memory, and I/O (input/output) lines onto one chip. The computer-on-a-chip patent, called the microcomputer patent at the time, U.S. Patent 4,074,351, was awarded to Gary Boone and Michael J. Cochran of TI.
Processors are vital to running all our computerized devices, even if we hardly ever think about them. That's why it's a big deal that they have major vulnerabilities, such as Spectre and Meltdown, that leave them open to hacking attacks. As they run all the essential processes on your computer, these silicon chips handle extremely sensitive data.
