Summary

Network+ is CompTIA's new and highly coveted certification credential that's designed to test the skills of basic, vendor-neutral network technicians. Network+ is vital whether you want to use it to establish yourself as a nuts-and-bolts tech, now very much in demand, or as a springboard to the MCSE and CNE certifications. Book jacket.
