Hi,
Here is a link to the "administration" of a small business:

I give this link because it shows the differences between "administration" and "management". As the answer before mine said, Administration is the "company" level, such as the CEO, or President, or Stock Holders, and Management is the lower levels, normall, such as management of payroll, human resources management, insurance, etc.
