Comparing the Dual Banach Space with norm topology and Weak* topology If we consider the dual Banach space $V' :=\{f:V\rightarrow \mathbb{C}$ such that $f$ is linear and bounded$\}$. We know $V'$ also forms a Banach space in the norm topology where the norm is the general operator norm. But the open ball is not compact in the norm topology (V is not finite dimensional), but it is so by the weak* topology by the Banach Alaoglu Theorem.
My question is that are these two topologies i.e. the norm topology and the weak* topology comparable, i.e. is one of them weaker than the other?
The second question is, whether $V'$ is still a Banach space with the weak* topology?

Every $weak^{*}$ open set is open in the norm topology. These two topologies coincide iff the space is finite dimensional. $V'$ with $weak^{*}$ topology is a Banach space iff $V$ is finite dimensional. [This is an  easy consequence of Banach Alaoglu Theorem].
