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. In addition, this books explains not only how to choose and configure network hardware but also provides practical information about the types of network devices and software needed to make it all work. Tips and direction on how to manage an Ethernet network are also provided. This book therefore goes beyond the hardware aspects of Ethernet to look at the entire network from bottom to top, along with enough technical detail to enable the reader to make intelligent choices about what types of transmission media are used and the way in which the various parts of the network are interconnected.

Regardless of the type of Ethernet you choose, the basic way in which data are packaged to travel over the network and the way in which devices gain access to the network media remain the same In this chapter we will therefore look at both the packaging of the data and the way that Ethernet provides media access control However, before we can look at the physical layer in depth, you need to know how the upper... Because each wire in the cable can carry only one bit at a time, you need to bundle 32 wires together to obtain the desired bandwidth (If they aren't close together, it will be next to impossible to fit a connector to them.) Unfortunately, the wires in the cable tend to leak signals to one another The closer the wires are bound and the longer they get, the worse the interference Therefore, parallel transmission... You can have Ethernet, or you can have Ethernet, and if you don't like that, you can have Ethernet unless you go wireless, which as you will see later in this book, has some major issues (primarily security, but also performance) that make it problematic for all but the smallest networks Types of Ethernet Ethernet is actually a collection of networking standards, some of which are outdated and not used... identifies the standards that accompany each type of Ethernet cabling as we explore hardware details in the following chapters Simpo PDF Merge and Split Unregistered Version - http://www.simpopdf.com 19 A Bit of Ethernet History A Bit of Ethernet History Originally, Ethernet was the brainchild of one person: Robert Metcalfe In the early 1970s, while working at Xerox PARC on the "office of the future"... 1983 Later, Ethernet was also endorsed as a standard by the ISO Ethernet is therefore an international standard for one way in which nodes on a LAN can gain access to transmission media Throughout its history, Ethernet has moved to faster and faster standards: 1986: The standard for 10BASE2 was approved, still running at 10 Mpbs 1991: The standard for 10BASE-T was approved Although still running at 10... install, and manage a network in such an environment, then this book will give you an understanding of the technology involved in an Ethernet network It will teach you how Ethernets work and what you need to put one together Probably the toughest part of understanding networks is the jargon If you're unfamiliar with networking terminology and acronyms, then a sentence like "To hook up to the legacy... from the roles taken by clients and servers over a network Client~server data processing implies that the major part of the software is running on the server (for example, a database management system, DBMS) The client formulates a request to the server (perhaps a query for data from a database) which is then sent to the server over the network The server processes the request and sends back unformatted, .
