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.
The OSI Reference Model is useful because it gives some commonly used terminology,
though it might mislead you into thinking that there is only one way to construct a network. The
reference model was designed by an organization known as the International Standards Organiza-
tion (ISO). The ISO decided it would be a good idea to standardize computer networking. Since
that was too big a task for a single committee, they decided to subdivide the problem among several
committees. They somewhat arbitrarily chose seven, each responsible for one layer.
MCSE Training Guide: Networking Essentials, Second
Edition is designed for advanced end-users, service technicians,
and network administrators with the goal of
certification as a Microsoft Certified Systems Engineer
(MCSE). The “Networking Essentials” exam (70-058)
measures your ability to implement, administer, and
troubleshoot information systems that incorporate
Windows 95 as well as any of the BackOffice family of
products. According to Microsoft, the exam covers only
the networking knowledge and skills common to both
Windows 95 and BackOffice products....
Chapter 1 targets the following objectives in the Standards and Terminology section of the Networking Essentials exam:
Compare a client/server network with a peer-topeer network.
. This objective makes sure you are familiar with the two main network classiﬁcation models.
Deﬁne common networking terms for LANs and WANs.
. The purpose of this objective is to make sure people working in the networking ﬁeld understand the difference between a local area network (LAN) and a wide area network (WAN). These terms are the main topics of discussion throughout this chapter.
This CLI Reference Guide is designed to help HP partners and customers who:
Manage multi-vendor networks that include HP and Cisco switches
Have experience deploying Cisco switches and are now deploying HP switches
This CLI Reference Guide compares many of the common commands in three switch operating systems:
HP ProVision, Comware 5, and Cisco operating systems.
The HP ProVision operating system runs on HP 3500, 5400zl, 6200yl, 6600, and 8200zl Switch Series.
(Other HP switches use an operating system that is very similar to the ProVision operating system.
Guided - wire
Unguided - wireless
Characteristics and quality determined by medium and signal
For guided, the medium is more important
For unguided, the bandwidth produced by the antenna is more important
Key concerns are data rate and distance
The rapidly changing pace of information technology leads to acronyms and terms being created and used
seemingly overnight. This glossary is a guide to the most commonly used and confused IT terms designed to
help managers better communicate with (and understand) their IT staff.
This version of the Common Criteria for Information Technology Security Evaluation (CC v3.1) is the first major revision since being published as CC v2.3 in 2005.
CC v3.1 aims to: eliminate redundant evaluation activities; reduce/eliminate activities that contribute little to the final assurance of a product; clarify CC terminology to reduce misunderstanding; restructure and refocus the evaluation activities to those areas where security assurance is gained; and add new CC requirements if needed....
