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.
CPU. In a PC, the central processing unit (CPU) is the primary control device for the entire computer system. The CPU is technically a set of components that manages all the activities and does much of the heavy lifting in a computer system. The CPU interfaces, or is connected, to all of the components such as memory, storage, and input/output (I/O) though communications channels called busses.
