Electronic Communications: A Systems Approach provides a comprehensive overview of wireless and wired, analog and digital electronic communications technologies at the systems level. The authors’ carefully crafted narrative structure helps readers put the many facts and concepts encountered in the study of communications technologies into a larger, coherent whole. Topics covered include modulation, communications circuits, transmitters and receivers, digital communications techniques (including digital modulation and demodulation), telephone and wired computer networks, wireless communications systems (both short range and wide area), transmission lines, wave propagation, antennas, waveguides and radar, and fiber-optic systems.  The math analysis strikes a middle ground between the calculus-intensive communications texts intended for four-year BSEE programs and the math-avoidance path followed by some texts intended for two-year programs.

Thoroughly updated to reflect the CompTIA® Network+ N10-008 exam, Networking Essentials, Sixth Edition is a practical, up-to-date, and hands-on guide to the basics of networking. Written from the viewpoint of a working network administrator, it requires absolutely no experience with either network concepts or day-to-day network management.

Networking Essentials, Sixth Edition guides readers from an entry-level knowledge in computer networks to advanced concepts in Ethernet networks; router configuration; TCP/IP networks; routing protocols; local, campus, and wide area network configuration; network security; wireless networking; optical networks; Voice over IP; the network server; and Linux networking. This edition reflects the latest exam topics and objectives associated with network security and hardening, cloud networking, virtualization, 5G, and other recent advances in wireless technology, infrastructure management, and current hardware and devices. It also explains many new terms now addressed by CompTIA’s N10-008 exam.

Clear goals are outlined for each chapter, and every concept is introduced in easy-to-understand language that explains how and why networking technologies are used. Each chapter is packed with real-world examples and practical exercises that reinforce all concepts and guide you through using them to configure, analyze, and fix networks.
