hello sir, i have completed my b.e. in e.c in 2010. now i want to do course of embedded system from ism banglore . i want to know should i go for c.c.n.a. or embedded sytem? i am a bit confused.

Better do your embedded course at institutes like CDAC and DOEACC to add value to your profile. Quality education counts. I am not aware of ISM, any way. CCNA is only a certification, not a qualification, if I am not wrong. You can do it part time/along with other courses .
