Technology simplified. This blog explains Computers and Networking basics in simple words which transfers my knowledge to others and to review myself the explained concepts in future. Our vision is to help our readers to understand the basic concepts of PC and networking. This little effort may help CCENT, CCNA and A+ certifications study group.
