Cisco administration 101: Learn 10 commands to configure on a new router When it comes to configuring a new Cisco router, much of the configuration depends on what type of router it is as well as the purpose it will serve. However, there are certain things you should configure on every new Cisco router. Hasn't there been a command that you wished Cisco would make standard on every router? Every administrator has his or her own list of commands they use to configure a router "just right." Here's my list of 10 commands that I think you should configure on every router (in no particular order). After you read through them, post your own favorites in this article's discussion.

Here's an example: Router(config)# username root secret My$Password Set a hostname on your router Router(config)# hostname Router-Branch-23
i-Net Media | Internet Media & IT Solutions Solar panel Photovoltaic solar panels absorb sunlight as a source of energy to generate direct current electricity. A photovoltaic (PV) module is a packaged, connected assembly of photovoltaic solar cells available in different voltages and wattages. Photovoltaic modules constitute the photovoltaic array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications. The most common application of solar energy collection outside agriculture is solar water heating systems.[1] Theory and construction[edit] A PV junction box is attached to the back of the solar panel and functions as its output interface. Module electrical connections are made in series to achieve a desired output voltage or in parallel to provide a desired current capability (amperes) of the solar panel or the PV system. Solar panels also use metal frames consisting of racking components, brackets, reflector shapes, and troughs to better support the panel structure.[2] History[edit]

L'IP c'est quoi ? Qu’est-ce qu’une adresse IP ? Une série de 4 nombres, séparés par des points compris entre 0 et 255 – sous la forme IPV4 ou IPV6. C’est votre identifiant, permanent ou dynamique et toujours unique à chaque ordinateur, imprimante ou périphérique sur un réseau. Tous les ordinateurs ont au moins deux adresses IP, une interne et l’autre externe. Le premier est utilisé pour identifier votre appareil sur un réseau à la maison, même si vous n’avez qu’un seul ordinateur connecté à ce réseau. L’adresse IP externe est utilisée pour la navigation sur Internet Lorsque vous allumez votre ordinateur et le connecter à un réseau local, l’appareil reçoit une adresse IP qui est communément appelée IP interne. Deux appareils ne peuvent pas avoir la même adresse IP sauf s’ils sont connectés dans le même réseau local ou privé. Découvrir ce nombre est assez facile et peut être utile pour diverses situations, comme nous le verrons dans cet article. À quoi sert l’adresse IP ? Votre ordinateur est reconnu
