One of the major goals of this book is to demystify the jargon of networks so that the reader gains a working familiarity with common networking terminology and acronyms. If you need to design, install, and manage a network in such an envronment, i.e., home or small business office, then Ethernet Networking for the Small Office and Professional Home Office will give you an in-depth understanding of the technology involved in an Ethernet network. Ethernet networking is used primarily by networks that are contained within a single physical location. Ethernet is a MAC protocol it is one way to regulate physical access to network tranmission media. Therefore, there must be some way to regulate which node has control of the medium (a media access control, or MAC, protocol). However, a network cable or wireless transmission frequency can physically only allow one node to use it at a given time. In a local area network (LAN) or intranet, there are many pieces of hardare trying to gain access to the network transmission media at the same time (i.e., phone lines, coax, wireless, etc.).
