1 p 36 Nonetheless, the Ethernet header contains a field called EtherType, which is filled in by the sending node to identify the specific packet being carried in the Ethernet frame. As examples, IPv4 is EtherType 0800, and IPv6 is EtherType 86DD. This field is quite valuable for organizations that are migrating to IPv6 but still have IPv4 components to support. In effect, dual stacks of software are maintained, and the EtherType fiel is used to pass the IP packet to the process in the appropriate software protocol stack.

1 p 45 IPX
The IPX protocol is derived from a Xerox Network Services (XNS) product and is part of Novell’s NetWare operating system. IPX uses an address similar to the conventional IP classful address, but it makes some adjustments for the sake of efficiency. IPX was widely used in the 1980s and 1990s, but it has seen diminishing use as the industry has migrated to IP. A survey on the Internet3 revealed that 44% of companies using Windows Server did not run IPX; 34% ran IPX but were migrated away

1 p 63 Cooperative multitasking prevents the OS from making all decisions about which application’s tasks are given system resources, such as the CPU. When an application is done with a task, resources are passed to another application. Preemptive multitasking has the OS making the decisions about which program gains use of the systems resources. Preemptive multitasking is the model used in Linux, UNIX, Microsoft’s Windows enterprise operating systems (Windows 2000, XP, 2003, and so on), and NetWare.

1 p 84 The NetWare product has been superseded by the Open Enterprise Server (OES). This system provides all the services of a typical SOS, and it can run over either Linux or a NetWare core platform. It appears the NetWare community might migrate to Linux, but as of this writing, it’s too soon to read these tea leaves. Presently, NetWare has a large customer base, and Novell is unlikely to do anything to alienate this population. There’s good reason for NetWare’s popularity: It is a fine product.

You need to spend time researching the hardware you’ll deploy: the servers, client computers, and network connectivity devices.

1 p 212 Groupware consists of a suite of software modules that allow users to communicate and collaborate with each other. Some people use the term collaborative software or workgroup support systems to describe this concept. At the desktop, the client side of these applications is collectively referred to as a Personal Information Manager (PIM).

1 p 290 1 In Outliners, Malcolm Gladwell devotes a good part of a chapter to Bill Joy, his exploits at school, and later at Sun Microsystems. Gladwell says, “He is sometimes called the Edison of the Internet.” Perhaps Gladwell should read up a bit more on the history of the Internet, as Joy came along some 15 years after the brilliant men at ARPA had already put on and taken off their Edison hats regarding the Internet. What Joy did was write another version of UNIX. He didn’t invent the Internet. I make this footnote to acknowledge the ARPA engineers about the matter. 1 In Outliers, Malcolm Gladwell devotes a good part of a chapter to Bill Joy, his exploits at school, and later at Sun Microsystems.

1 p 386 Efforts began in the 1990s to create libraries of programmable DNA parts, a discipline called synthetic biology. The goal was to create general components that could be used in more than one DNA application.2 These plug-and-play parts could be like a generic capacitor used in electrical hardware circuits, or a generic perpetual calendar routine used in accounting software packages. Researchers have dubbed this technology “BioBricks.” Efforts began in the 1990s to create libraries of programmable DNA parts, a discipline called synthetic biology.
