Autoren-Porträt von William Stallings
Dr. William Stallings has made a unique contribution to understanding the broad sweep of technical developments in computer security, computer networking, and computer architecture. He has authored 20 textbooks, and, counting revised editions, more than 75 books on various aspects of these subjects. His writings have appeared in numerous ACM and IEEE publications, including the Proceedings of the IEEE and ACM Computing Reviews. He has 13 times received the award for the best computer science textbook of the year from the Text and Academic Authors Association.In over 30 years in the field, he has been a technical contributor, a technical manager, and an executive with several high-technology firms. He has designed and implemented both TCP/IP-based and OSIbased protocol suites on a variety of computers and operating systems, ranging from microcomputers to mainframes. Currently he is an independent consultant whose clients have included computer and networking manufacturers and customers, software development firms, and leading-edge government research institutions.
He created and maintains the Computer Science Student Resource Site at ComputerScienceStudent.com. This site provides documents and links on a variety of subjects of general interest to computer science students (and professionals). He is a member of the editorial board of Cryptologia, a scholarly journal devoted to all aspects of cryptology.
Dr. Stallings holds a PhD from M.I.T. in computer science and a B.S. from Notre Dame in electrical engineering.
