Technology exchange agreement with Intel. Intel had introduced the first x86 microprocessors in 1978. In 1981, IBM created its PC, and wanted Intel's x86 processors, but only under the condition that Intel also provide a second-source manufacturer for its patented x86 microprocessors.
The ear canal is shaped somewhat like an hourglassnarrowing part way down. The skin of the outer part of the canal has special glands that produce earwax. This wax is supposed to trap dust and dirt particles to keep them from reaching the eardrum.
A retracted eardrum is a condition whereby the eardrum is sucked or pulled into the area behind it. This may arise due to low pressure in middle ear area.
