Features: Cisco, a world-famous network systems company established in the 1980s, is primarily dedicated to the development, production, and sales of high-end routers, switches, and network interconnection devices. Its products are widely used in local area networks (LANs), wide area networks (WANs), and the Internet. In the internet world dominated by Microsoft, Cisco is the true uncrowned king in the fields of routing and switching. Due to the high technical content and complex principles of Cisco's products compared to ordinary computer software and hardware products, learning and mastering their working principles and usage methods require extensive relevant knowledge and practical experience. To ensure that technicians responsible for using, managing, or providing services for Cisco products possess the necessary technical proficiency, Cisco has established a series of certification exams. Moreover, the objectives and content of these exams continue to evolve with its products. To cover the new exam objectives, we adopt the approach of "original import, reformatting and printing" to publish a series of Cisco certification exam preparation books at the fastest speed to meet reader demand. This book, as part of the series, is designed for the CCNA: 640-801 exam. The content begins with an introduction to networking and TCP/IP background, then covers subnetting, Cisco's network operating system, and the command-line interface, followed by routing and switching, and finally introduces VLANs and WANs.
