Competency-based learning for the academic classroom. Developed for academic courses, A+ CERTIFICATION, Fourth Edition, helps students build the skills they need on the job and for the CompTIA A+ Core Hardware and Operating System Technologies exams. The textbook delivers courseware adaptable for a full 16-week semester or a 6-week, 8-week, or 10-week course. The book is filled with competency-based practice exercises that students complete on their own, while the companion lab manual features additional skill-building activities ideal for your classroom's computer lab. Along with the textbook and lab manual, students get a Student CD-ROM containing study aids, demonstration videos, an electronic version of the textbook, and information on how to begin a career in Information Technology. An Instructor CD-ROM containing a complete set of instructor support materials -- including lecture outlines, teaching tips, PowerPoint slides, a test bank, and detailed lab set-up instructions -- is also available. In conjunction with A+, Network+ may be used as a substitute for your MCSA program's elective course requirement.
