Its used to detect an error if the packet may be mis-routed. I'm not 100% sure.

Frame Check Sequence

a serial interface on a router is basically used for WAN communications. we generally connect to other routers through internet using serial interface. In a lab scenario we generally emulate WAN connections by connecting the serial interfaces of the routers using a cable called DCE/DTE cable.

Transport (OSI)

Since the fundamental task of a firewall is to filter packets, the weak point in its traditional behavior is the fact that it also must route packets after a decision is made. Can the model be simplified? Of course it can, and the answer comes by stepping down a layer in the OSI model. Instead of the device handling packets at layer 3 (network), what if it merely inspected frames and moved them to the proper interface? Sound familiar? This type of device would continue to filter packets, but operate at layer 2 (data link), like a bridge. Such a device has come to be known by several names: a transparent, in-line, shadow, stealth or bridging firewall.

LAN can be connected by routers . A router can be used to connect to LAN's .a LAN to a WAN and LAN to Internet.

A router running a classless routing protocol (Such as OSPF) will send the subnet mask in its route updates to its neighboring routers.

Cisco modems can vary in price from anywhere starting at $70 all the way up to $1000. The pricier modems are typically used for places which need fast speed for many devices, such as a business.

You want to totally reinitialize the router and replace the current running-config with the current startup-config. What command will you use?

These are high-speed serial interfaces that will connect to a Telco's equipment which provides you with leased-line or frame-relay connectivity.

Which two technologies can be used in distance vector routing protocols to prevent routing loops?

2 Ports on the router however you can add more cards to the device. In a 2821 you can add 4 cards such as WICs and in a 2811 you can add 2 cards.

Look up your Labor Relation Laws. Type in "Google" Then go to American Labor Relation Laws or Canadain Labor Relation Laws I know every company has to give you a 10 - 15 min. break every few hours, but I'm Canadian and not sure what yours is. Marcy

Since "The Company" is asking nothing illegal from its employees in making such a request, there is nothing illegal involved by virtue of their request. What the officials of any company promise to employees is just a promise; and, things change. When it is no longer considered to be of benefit to a company to support such promises, revisions are made. In addressing these issues, it is not morality that is at stake--- it's business; and, there are a lot of things that may be "wrong" for a company to do that are in no way illegal. As far as the company asking the employees to avoid doing something which otherwise would be in the employees' interests to do, that's not illegal. If company policy provided you with "benefit-X" upon request, and the company decides to revise their benefits package to eliminate that option, there's nothing illegal about it--- regardless the reason the company might have for doing so. When it involves something like a 401-K plan, the details are a bit more intricate; but, there are never any "guarantees" for an employee that are not written in a black-and-white contract and/or supported by solid legislation. In the employment arena, the employer has the upper hand in most regards; and, it is best to remember one thing as you watch jobs and pensions and benefits packages evaporate around you this year: A promise is a promise is a promise, regardless of age...

There is not Fullform of PROTOCOL..If we say in simple language, PROTOCOL is just a type of program or utility to transfer data from source to destination. Precisely it can be defined as rule or a standard to do particular operation.

Data cannot be transferred until a circuit has been established

Certified Network Associate (Cisco CCNA) certification demonstrates your knowledge to deploy, maintain, secure and operate a medium-sized network using Cisco technolo-gies. Cisco 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.
