802.11 Wireless Local-Area Network Fundamentals

Author: Pejman Roahan

Master the basics in designing, building, and managing a Cisco Aironet WLAN.

• Master the basics of Wireless LANs with this concise design and deployment guide
• Understand implementation issues for a variety of environments including vertical, SOHO, and enterprise networks
• Learn design and troubleshooting advice from real-world case studies

802.11 Wireless LAN Fundamentals gives networking engineers and IT professionals the knowledge they need to design, deploy, manage, and troubleshoot their own wireless local-area networks (WLANs). Starting with an overview of the technology and architecture of WLANs, the book goes on to explain services and advanced features that such applications can provide. Most importantly, it provides practical design guidance and deployment recommendations.

Wireless LANs connect computer networks via radio transmissions instead of traditional phone lines or cables. Benefits to these systems go well beyond getting rid of all the cables and wires. Campus networks can grow geographically larger while still retaining all their efficiency and speed. Additionally, cost savings can be realized when third-party phone lines are no longer necessary, saving the cost of line rental and equipment upkeep. Finally, flexibility in campus network design increases significantly for the networking professional, while the network accessibility and usefulness increases for the individual users.

802.11 Wireless LAN Fundamentals helps networking professionals realize these benefits by helping them understand how to design, build, and maintain these networks, as well as how to justify their valuewithin organizations.

Compressed Image File Formats: JPEG, PNG, GIF, XBM, BMP

Author: John Miano

This comprehensive reference on the major graphics file formats and the compression technologies they employ is an indispensable resource for graphics programmers, especially those developing graphical applications for the Web.

Compressed Image File Formats: JPEG, PNG, GIF, XBM, BMP examines the most common graphics file formats in detail and demonstrates how to encode and decode image files for each. In particular, this book offers in-depth coverage of the elaborate JPEG and newer PNG formats, providing clear explanations of complex concepts, experience-based practical techniques, and plentiful code examples. GIF, XBM, and BMP are also covered, with a focus on some of the less familiar and less well-documented features of these common file formats.

Specific topics covered include:

• Compression technologies that each file format utilizes
  
• Color models employed by each file format
  
• The advantages and disadvantages of each file format
  
• Huffman Coding
  
• LZW Compression
  
• Deflate/Inflate
  
• Progressive JPEG
  
• The Discrete Cosine Transform
  
• Animated GIF
  

The accompanying CD-ROM contains the complete source code for all of the image formats covered in the book, as well as working examples and sample images. If you want to learn how to read and write graphic file formats for the Web--including PNG and JPEG files--there is no better resource than this book. System requirements: Windows 95 or Windows NT, Borland C++ Builder 3, or Microsoft Visual C++ 5.0.
