All 5 cd Course Rapidshare/Pointupload

Description

The CCNA certification (Cisco Certified Network Associate) indicates a foundation in and apprentice knowledge of networking. CCNA certified professionals can install, configure, and operate LAN, WAN, and dial access services for small networks (100 nodes or fewer), including but not limited to use of these protocols: IP, IGRP, Serial, Frame Relay, IP RIP, VLANs, RIP, Ethernet, Access Lists.

Course Features:

* Main Menu
Move through hours of in-depth content - quickly and easily due to the efficient and organized structure.
* PowerPoint
Utilizing PowerPoint presentations enhances the delivery by displaying a variety of visual information to the user. This type of representation allows the user to better interpret the material through charts, definitions, graphs, and more...
* Controls
Move forward, back, and repeat entire topics or just a section. A progress bar illuminates as you advance through exercises.

* Full Motion Video
All courses feature full-motion videos of instructors teaching the information as if they are speaking directly to you. Our unique delivery simulates a one-on-one classroom environment creating a more personal lesson and learning experience.
* Study Guides
Printable study guides for the entire course are available. This allows all material to be viewed, reviewed, and printed for viewing at a later date.
* Review Exercises
Each section has a review quiz to aid in the learning process by validating the comprehension of the material covered before moving on to a new section.
* Resume
All courses are resumed to where you left off last session allowing you to learn when it is convenient for you without the hassle of remembering where you where.
* Live Demonstrations
Demonstrations are a way for the instructor to show and tell the user how to perform a task by actually doing it on screen in front of them. In this format it gives the user the power to see things done by a professional in the intended environment as many times as they would like.

		Digital Simulators Digital Simulator : Digital Simulator has a toolbar of digital circuit elements, including logic gates, flip-flops, switches, and indicators. Drawing a circuit with Digital Simulator is like using a paint program. You click the element's icon on the toolbar, then click where you want the element to go. You use a similar procedure to draw wires and indicate connections. It's that simple. Edison 4 for Windows : Edison Version 4 provides a unique new environment for learning electricity and electronics. Teachers, students and electronics enthusiasts can use digitally scanned photo realistic components, a solder less breadboard, virtual instruments, sound and animation to create, test, and safely repair lifelike 3D circuits and simultaneously see the corresponding circuit schematic. Edison also comes with over 100 experiments and problems that teachers and students can use immediately. Aimspice : download a student version from their site. Anasoft : Schematics entry integrated with industry standard SPICE 3f5 engine, the demo which can be downloaded from the website seems to work well. Your own symbols and components can be added via the symbol editor. Beige Bag : A neat looking integrated simulator on their site, with a 30 day fully functional trial version. Lots of models too... Check it out! Circuit Designer Pro : Eagle schematics and PCB layout : This is not a simulator, but a schematic capture and routing tool which I understand can integrate with SPICE. Includes auto-routing facility, and a large library of components. Hobbyists edition available for non-commercial use, free of charge with a maximum board size of 100mm x 80mm with two layers. EAGLE runs on Windows� 95, Windows NT�, Linux and MS-DOS�, and registered editions start at $49 which includes telephone tech support. Electronic Workbench : Very easy to use with package scaling for Personal, Student and Pro versions. Uses real world DMM's and Scopes to provide results of simulations. Integrated PCB placement software now available too. MicroCap 5 : Costs $3,495 although a student/demo version is available for download [1.75MB]. Orcad : The makers of Pspice integrated schematic capture, simulation, and PCB routing suite. All of their tools are available on a CD which is sent free on request - this is a fully working suite limited to 60 components and some restrictions on the libraries SIMetrix : A UK developed simulator with schematic capture linked to spice 3.x. You can download an almost fully functional demo, limited by a 30 second run time (2 megs in size). TopSpice by Penzar : "An affordable integrated computer-aided circuit design software package offering advanced native mixed-mode mixed-signal analog/digital/behavioral simulation based on the industry standard SPICE program." More news when I've checked their demo out (2mb). Winspice3 by Mike Smith : An excellent port to Windows 95/NT of the traditional SPICE 3f4 engine. Now enhanced to handle some of the 2g6 specific statements.

Reference Color Codes in HTML

Reference Color Codes When you're adding a color to your Web page with HTML, sometimes you can just type in the name of the color.
