How to use LANs to help your company grow A vital component of today’s business, Local Area Networks (LANs) allow organizations to link their computers together for maximum work sharing, collaboration among geographically disparate teams, and other essential business functions. This book helps system administrators and IT professionals set up LANs and Intranets in a way that will contribute to their company’s growth and success. Beginning with the theoretical foundation for LAN operation and design, it covers the applicable data communications principles, then goes on to explore both LAN hardware and infrastructure design, network operating systems, LAN management and security. The book also gives a practical introduction to the world’s most popular network operating systems—Windows 2000, Novell NetWare, and Linux. Finally, the book takes an in-depth look at business and management issues, with special emphasis given to the impact of Intranets on business goals.

"This course discusses the WAN technologies and network services required by converged applications in a complex network. The course allows you to understand the selection criteria of network devices and WAN technologies to meet network requirements. You will learn how to configure and troubleshoot network devices and resolve common issues with data link protocols. You will also develop the knowledge and skills needed to implement IPSec and virtual private network (VPN) operations in a complex network."--Back cover.

No previous knowledge of data communications and related fields is required for understanding this text. It begins with the basic components of telephone and computer networks and their interaction, centralized and distributive processing networks, Local Area Networks (LANs), Metropolitan Area Networks (MANs), Wide Area Networks (WANs), the International Standards Organization (OSI) Management Model, network devices that operate at different layers of the OSI model, and the IEEE 802 Standards. This text also introduces several protocols including X.25, TCP/IP, IPX/SPX, NetBEUI, AppleTalk, and DNA. The physical topologies, bus, star, ring, and mesh are discussed, and the ARCNet, Ethernet, Token Ring, and Fiber Distributed Data Interface (FDDI) are described in detail. Wiring types and network adapters are well covered, and a detailed discussion on wired and wireless transmissions including Bluetooth and Wi-Fi is included. An entire chapter is devoted to the various types of networks that one can select and use for his needs, the hardware and software required, and tasks such as security and safeguarding data from internal and external disasters that the network administrator must perform to maintain the network(s) he is responsible for. Two chapters serve as introductions to the Simple Network Management Protocol (SNMP) and Remote Monitoring (RMON). This text includes also five appendices with very useful information on how computers use numbers to condition and distribute data from source to destination, and a design example to find the optimum path for connecting distant facilities. Each chapter includes True-False, Multiple-Choice, and problems to test the reader's understanding. Answers are also provided.
