•As PC became more common, it became obvious one would need
to share data and peripherals between them efficiently.Floppy discs could not be the solution. Hence the idea of a
network.•The necessities to have one database that many users can
access simultaneously made networking very relevant.•Great demand to share devices ( e.g. printer sharing in companies).
Cisco Systems, Inc., the worldwide leader
in networking for the Internet, has
prepared this guide to make networking
easier for your campus or district. If
you’re new to networking, it’s an ideal
introduction, starting with the most basic of components and helping you pinpoint the
best technologies and design for your network. If you already know your networking
ABCs, look to this guide for straightforward explanations of key terms and concepts to
keep building your knowledge base.
OpenVPN is a powerful, open source SSL VPN application. It can secure site-to-site connections, WiFi and enterprise-scale remote connections. While being a full-featured VPN solution, OpenVPN is easy to use and does not suffer from the complexity that characterizes other IPSec VPN implementations. It uses the secure and stable TLS/SSL mechanisms for authentication and encryption. This book is an easy introduction to this popular VPN application.
Network management is the poor cousin of network design and implementation.
All too often it is treated as an inconvenience by equipment manufacturers, or
forgotten entirely. But the ability to manage network devices is fundamental to
their utility, and a successful and functional network can only be built from equipment
that can be easily managed and operated.
Management refers to the ability to confi gure, control, operate, and diagnose
equipment. Of course, no vendor ships devices that cannot be managed, but
typically each is operated and controlled in a different way.
This document is intended to guide customers in their planning or deployment of IPv6 in branch
networks. This document is not meant to introduce you to branch design fundamentals and best
practices, IPv6, transition mechanisms, or IPv4 and IPv6 feature comparisons. The user must be familiar
with the Cisco branch design best practices recommendations and the basics of IPv6 and associated
transition mechanisms. For information about the enterprise design architecture, refer to the following
William Stallings' Cryptography and Network Security: Principles and Practice, 5e is a practical survey of cryptography and network security with unmatched support for instructors and students.
In this age of universal electronic connectivity, viruses and hackers, electronic eavesdropping, and electronic fraud, security is paramount. This text provides a practical survey of both the principles and practice of cryptography and network security.
This book guides readers through the basics of rapidly emerging networks to more advanced concepts and future expectations of Telecommunications Networks. It identifies and examines the most pressing research issues in Telecommunications and it contains chapters written by leading researchers, academics and industry professionals. Telecommunications Networks - Current Status and Future Trends covers surveys of recent publications that investigate key areas of interest such as: IMS, eTOM, 3G/4G, optimization problems, modeling, simulation, quality of service, etc.
An Introduction to Networking
List the advantages of networked computing relative to standalone computing
Distinguish between client/server and peer-to-peer networks
List elements common to all client/server networks
Describe several specific uses for a network
Identify some of the certifications available to networking professionals
Identify the kinds of nontechnical, or “soft,” skills that will help you succeed as a networking professional
Transmission Basics and Networking Media
Explain basic data transmission concepts, including full duplexing, attenuation, and noise
Describe the physical characteristics of coaxial cable, STP, UTP, and fiber-optic media
Compare the benefits and limitations of different networking media
Identify the best practices for cabling buildings and work areas
Specify the characteristics of popular wireless transmission methods, including 802.11, infrared, and Bluetooth
This lab exercise focuses on the basics of IP subnet masks and their use with TCP/IP networks. The subnet mask can be used to split up an existing network into subnetworks, or subnets. Some of the primary reasons for subnetting are the following:
• Reduce the size of the broadcast domains, which creates smaller networks with less traffic
• Allow LANs in different geographical locations to communicate through routers
• Provide improved security by separating one LAN from another
Routers separate subnets, and determine when a packet can go from one subnet to another.
In data networking, transmit means to issue signals to the network medium
Transmission refers to either the process of transmitting or the progress of signals after they have been transmitted
The ability to effectively troubleshoot computer related problems is an important skill. The process of
identifying the problem and solving it requires a systematic step-by-step approach. This lab will
introduce some basic hardware and software related problems to solve. This lab will assist in
becoming more familiar with PC components and the software required to use the Cisco curriculum.
The process of solving a problem is fairly straightforward. Some of the suggestions here are more
than what will be required to solve basic hardware and software problems.
In-Depth TCP/IP Networking
Understand methods of network design unique to TCP/IP networks, including subnetting, CIDR, NAT and ICS
Explain the differences between public and private networks
Describe protocols used between mail clients and mail servers, including SMTP, POP3, and IMAP4
Employ multiple TCP/IP utilities for network discovery and troubleshooting
This chapter aims to introduce the basic concepts of satellite networking including appli-
cations and services, circuit and packet switching, broadband networks, network protocols
and reference models, characteristics of satellite networks, internetworking between satellite
and terrestrial networks and convergence of network technologies and protocols. When you
have completed this chapter, you should be able to:
This book is about pricing issues in modern communications networks. Recent technology
advances, combined with the deregulation of the communication market and the
proliferation of the Internet, have created a new and highly competitive environment for
communication service providers. Both technology and economics play a major role in
this new environment. As recent events in the marketplace make clear, the success of a
communication services business is not guaranteed by new technology alone.
This book aims to explain the basics of graph theory that are needed at an introductory level for students in computer or information sciences. To motivate students and to show that even these basic notions can be extremely useful, the book also aims to provide an introduction to the modern field of network science. Mathematics is often unnecessarily difficult for students, at times even intimidating.
More than ever before, people are being asked to
make decisions and take responsibility for managing
their finances. This is an area that many people can
find daunting and confusing. For some, thinking
about their long-term financial security is dispiriting
or even distressing, particularly if they are struggling
to manage debt or other commitments.
The number and complexity of choices to be made
have increased dramatically over the last 25 years,
so that many find it hard to understand financial
products and the risks associated with them.
