the deffrence between consnant and vowel is
all vowels are voicesd.
several consonats voiced and voiceless
there is obstruction in vocal folds in consonats sound
there is no obstruction in vocal folds in vowels sound ( airflow freely),

the similarities b+m are
both voiced
both bilabial
M nasal stop
B oral stop

the mean of velic closure is when the velum is reaised air cannot escapes through nose and its sounds called oral.

africative is manner of articulation that sequences of stops + fricative
another meaning is stopping then realsing airflow through narrow opening
