Bentham explains these important concepts in detail and quite understandably.

Jeremy Bentham is co-founder of an industrial networking company (Io Ltd.) and its software consulting offshoot Iosoft Ltd., in Cambridge, England. An engineer by training, he has developed many computer systems in railway control and other industrial applications and a wide range of software tools for embedded systems. Networking projects included Bitup, a Bitbus emulation for the 80188 processor; data transfer protocols using Arcnet and Ethernet; and a full 801888-based remote-boot communications system using the simpler TCP/IP protocols (UDP and TFTP). Recent work has been in implementing embedded TCP/IP systems in aerospace, air quality, and video surveillance applications. In his spare time, Jeremy enjoys playing racquet sports, and is an accomplished amateur actor.
