Meaning of SHIM

Pronunciation:  shim

 
Computing Dictionary
 
 Definition: 

A small piece of data inserted in order to achieve a desired memory alignment or other addressing property. For example, the pdp-11 unix linker, in split I&D (instructions and data) mode, inserts a two-byte shim at location 0 in data space so that no data object will have an address of 0 (and be confused with the c null pointer).

See also loose bytes.
