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.

These sound waves vibrate the eardrum; the sounds are then transmitted to the bones of hearing (ossicles). The eardrum also protects the middle ear so debris and bacteria do not enter the middle ear.here are many ways an eardrum perforation can occur. An infection behind the eardrum in the middle ear may cause a rupture of the eardrum. Trauma to the ear may result from an object entering the ear canal and puncturing the eardrum.
