Where are $B$-cells and $T$-cells formed? How do they differ from each other?

(N/A) Both $B$-cells and $T$-cells are formed in the bone marrow through the process of hematopoiesis.
$B$-cells mature in the bone marrow,whereas $T$-cells migrate to the thymus to mature.
$B$-cells are responsible for humoral immunity (antibody-mediated immunity) by producing antibodies,while $T$-cells are responsible for cell-mediated immunity $(CMI)$ by activating phagocytes,antigen-specific cytotoxic $T$-lymphocytes,and releasing various cytokines.
