Depreciation under Company Law

Hello Friends, i  want to know about depreciation provision under Companies Act, 1956 sechdule XIV e.g. Rates of Depreciation for diffrent assets specifically regarding assets falling within computer equipment category. And the way to be adopted in case depreciation provided on the basis of quarterly basis varies from the Depreciation calculate on annual basis, is it to be adjusted in the last quarter. And information about prorata depreciation in case of addition and sale.

I haven't found it in the files section.
