Abstract
We review the advantages of fitting with a Two Component Advective Flow
(TCAF) which uses only four physical parameters. We then present the results of
hydrodynamic simulations to highlight the fact that the primary component of a
black hole accretion remains the sub-Keplerian or the low angular momentum flow
independent of whether we have a high, intermediate or low mass X-ray binary.
Every aspect of spectral and timing properties, including the disk-jet
connection could be understood well only if such a component is present along
with a Keplerian component of variable size and accretion rate.
