Support Alert Newsletter Issue 159,Free Edition As I described in a Special Announcement on July 9, Support Alert Newsletter is merging with the Windows Secrets Newsletter on July 24. Please see I've received many emails from readers since sending out that announcement wishing me well in this new enterprise. I thank you for your kind words and thoughts. Gadget news The Gadget Show competition – 14.4.2014 This week, we have a colossal prize bundle to give away to one lucky winner! And to make it even easier, there’s no question to answer! ICTs: device to device communication This unit looks at communication systems where devices are the main players, passing information to and from each other and possibly acting on that information to produce some kind of outcome. In these interactions, people may not be involved at all, or may have roles that are limited only to the initial setting of schedule (such as when certain tasks should be performed) and parameters (such as particular conditions that should be satisfied before a task is performed). Some people may see this as liberating – relieving humans from the tedious tasks of everyday living. Some may see it as threatening – taking control away from humans and placing it with the computers and machines. How do devices ‘talk’ to each other?
Home : Broadband ISP Reviews News Tools and Forums Pinned News News Google recently stated they were considering expanding Google Fiber to a list of 34 cities in nine metro areas. While New York City wasn't on the list, Geek.com has noticed that Google Fiber is advertising for a Google Fiber regional sales manager for the New York City region."As a Google Fiber Regional Sales Manager, you will manage multiple teams that evangelize Google Fiber services to MDU (multi-dwelling apartments and condos) and large SMB owners," notes the listing. "You will hire and manage a team that proactively reaches out and and articulates how Google Fiber Solutions can help make their work more productive."
Cisco Security Appliance Command Line Configuration Guide, Version 8.0 - Glossary [Cisco ASA 5500-X Series Next-Generation Firewalls] security association. An instance of security policy and keying material applied to a data flow. SAs are established in pairs by IPSec peers during both phases of IPSec. SAs specify the encryption algorithms and other security parameters used to create a secure tunnel. 64 Things Every Geek Should Know - laptoplogic.com The term ‘geek’, once used to label a circus freak, has morphed in meaning over the years. What was once an unusual profession transferred into a word indicating social awkwardness. As time has gone on, the word has yet again morphed to indicate a new type of individual: someone who is obsessive over one (or more) particular subjects, whether it be science, photography, electronics, computers, media, or any other field.
Generic Routing Encapsulation Example uses[edit] In conjunction with PPTP to create VPNs.In conjunction with IPsec VPNs to allow passing of routing information between connected networks.In mobility protocols.In A8/A10 interfaces to encapsulate IP data to/from Packet Control Function (PCF).Linux and BSD can establish ad-hoc IP over GRE tunnels which are interoperable with Cisco equipment.Distributed denial of service (DDoS) protected appliance to an unprotected endpoint. Example protocol stack[edit] Based on the principles of protocol layering in OSI, protocol encapsulation, not specifically GRE, breaks the layering order. It may be viewed as a separator between two different protocol stacks, one acting as a carrier for another.
Network Troubleshooting Tools By Glen E. Clarke, Edward Tetz, Timothy Warner The following is a listing of some common troubleshooting tools you should be familiar with for the A+ Exams. One of the challenging parts of supporting networks today is knowing how to troubleshoot them. You find so many aspects of the network that it is difficult to know where to start your troubleshooting. Crimper: A cable crimper is used to create network cables by attaching the connectors to the ends of the cable and then using the crimper to squeeze the connectors in place.Cable stripper: A cable stripper is used to strip the outer layer off the cable so that you can get access to the wires.Multimeter: A multimeter is used to test voltage and current and can be used to diagnose problems with a cable.Tone generator and probe: A tone generator is used to locate cables in a mess of cables.
TCP/IP Definitions By Candace Leiden, Marshall Wilensky Part of TCP/IP For Dummies Cheat Sheet Knowing your way around TCP/IP is key if you want to manage a network successfully. The definitions in the following list explain the basics, such as what an IP address is, and they also clarify the various nets you deal with — extranets, intranet, and subnetting — as well other key terms. Transmission time Packet transmission time = Packet size / Bit rate Example: Assuming 100 Mbit/s Ethernet, and the maximum packet size of 1526 bytes, results in Maximum packet transmission time = 1526×8 bit / (100 × 106 bit/s) ≈ 122 μs Propagation delay[edit] The transmission time should not be confused with the propagation delay, which is the time it takes for the first bit to travel from the sender to the receiver (During this time the receiver is unaware that a message is being transmitted). The propagation speed depends on the physical medium of the link (that is, fiber optics, twisted-pair copper wire, etc.) and is in the range of

Effective Planning and Analysis of Huawei and Cisco Routers for MPLS Network Design Using Fast Reroute Protection 1. Introduction In the 1990s, asynchronous transfer mode (ATM) was considered an ideal solution in transmission networks to operate with different demands [1]. Computer and Network Surveillance Open Access publishing movement started in early 2000s, when the academic leaders from around the world participated in the formation of the Budapest Initiative. They developed recommendations for Open Access publishing process “which has worked for the past decade to provide the public with unrestricted, free access to scholarly research—much of which is publicly funded. Making the research publicly available to everyone—free of charge and without most copyright and licensing restrictions—will accelerate scientific research efforts and allow authors to reach a larger number of readers.” (reference: IntechOpen’s co-founders, both scientists, created the company while doing research in robotics at the Vienna University. At IntechOpen, we are excited to be working with organizations and people who care about scientific discovery, put the academic needs of scientific community first, and provide an Open Access environment where scientists can maximize their contribution to humanity.
