Description

The CCNA Basics (CCNAB) course developed by Cisco Systems is recommended for CCNA preparation as a prerequisite to Interconnecting Cisco Network Devices (ICND). Focused on introducing networking techniques, terminology, and technology, CCNAB is for professionals training for CCNA without significant previous experience. This guide provides an understanding of commonly used networking technologies, the OSI reference model, basic functions of network protocols, and binary and hexadecimal number systems. This baseline knowledge is essential for understanding how to design, configure, and manage small networks. Terminology and technologies are explained in a straightforward, concise manner. Cisco CCNA Basics (CCNAB) Self-Study Guide covers major networking topics including IT basics, networking fundamentals, network types, network media, switching fundamentals, routing basics, WAN technologies, wireless technologies, optical networking, and voice/video/data systems. Sections begin with objectives and chapter overviews and end with summaries and review questions to help readers assess their knowledge. Upon completion of the book, readers will be able to describe computer hardware basics, understand basic networking terminology and internetworking concepts, identify the major components of a network system, and describe the operation of LANs, WANs, MANs (Metropolitan Area Networks), VPNs, Intranets, Extranets, storage area networks, and content delivery networks.show more
