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.
The eardrum (tympanic membrane) is a thin, oval layer of tissue deep in the ear canal. It helps protect the delicate middle and inner ear from the outside. It is called an eardrum because it looks and acts like a drum.The eardrum receives vibrations from the outer ear and transmits them to the small hearing bones (ossicles), of the middle ear. Because it is so thin, the eardrum can be ruptured or punctured. The hole exposes the middle and inner ear to damage or infection.t helps protect the delicate middle and inner ear from the outside.
