Governor limits are limits enforced by the Apex runtime engine to ensure that runaway Apex does not monopolize shared resources in the multitenant environment.

Governor limits are limits enforced by the Apex runtime engine to ensure that runaway Apex does not monopolize shared resources in the multitenant environment. These limits are tracked and enforced during the execution of Apex code and if a governor limit is exceeded an uncatchable runtime exception is generated, such as "Too Many SOQL Queries".
