Important questions
share it a link alone
Don't waste my hardwork and valuable time
Don't share as screenshot kind request
most viewed dept will get update at first So Dont screenshot and share

*These questions are expected for the exams This may or may not be asked for exams All the best.... from admin Santhosh
Thanks for your love and support guys keep supporting and share let the Engineers know about Us and leave a comment below for better improvements If there is any doubt feel free to ask me I will clear if I can or-else I will say some solutions ..get me through WhatsApp for instant updates ~$tuff$£ctorSYllabuSUNIT I SYSTEMS COMPONENTS AND THEIR REPRESENTATION
