In the industry of web hostings exists thousand of good and bad companies, who vendem lodging web. To find and to buy lodging web only in good web hostings is difficult. therefore, I compiled this list of 9 questions that you must make before choosing one web hosting.1. The frequency of backups? 2. Which are the tools and software that web hostings makes use to assure that my sites are always online? 3.

Which is the domain number that I can use in each plan of lodging web? 4. Which are the politics of payment and use of the company? 5. Which the way of functioning of the serving ftp? 6. I have access to the filing-cabinets of log and statisticians? 7. I can create email accounts, in web hosting? 8. What he is enclosed in the contract? 9.

The Net

Still in accordance with publication of the Techenet (2008), the computers customers DNS can use the LLMNR to decide names in a net segment when a server DNS is not available. If a roteador to fail, removing a sub-net of all existing servers DNS in the net, the existing customers whom LLMNR supports will be able to continue to decide names in a base point-the-point until the linking of the net is restored. 4,1 Resolution of In agreement Names using LLMNR RFC the 4795 (2007) consultations of the protocol are sent and received using door 5355. In the case of the Ipv4 the request is sent for the address, in relation to the Ipv6 is used address FF02: 0: 0: 0: 0: 0. In a simplified vision the process of resolution of names of – in the following way: first host responsible for the consultation sends the request for address multicast of the net, an addressee only responte the solcitiao if it will be autoritativo for the consultation, case is true the reply of the consultation is envida way address unicast by means of the protocol of transport UDP. When receiving respota host from origin processes the solicito and initiates the access of the desired resources of the user. RFC 4795 (2007).

The use of the address unicast can be used in the following situations: host of origin repeats the consultation later that it received from host of destination, or host of origin consults a register for a complete address IP being the version Ipv4 or Ipv6. RFC 4795 (2007). By measures of security the requests unicast must be carried through by the protocol of transports TCP, consutas deriving of connections TCP does not have to be discarded. RFC 4795 (2007). 4,2 Unicast verification Defined for RFC 4795 (2007), before sending a reply to the shipper, the receiver configured with one only address verifies if host in net LLMNR has one another one that is autoritativo for the same name of the interface.

So Paulo Communication

This collection is more intense when it is about those that act in the exploration and the use of the natural resources. However, the ambient awareness still is a consequence of the reflection of few and that it must be dealt with the society in the local scopes, regional, national, international and planetary (SAFE, 2001). We know that it is not easy task and that it is not gotten resulted significant in short time. This because the ambient awareness has that, obligatorily, to pass for a process of education of the population: ambient education (EA? Mattos and Simes-Mattos, 2009). The EA is a specific branch of the education whose objective is the dissemination of the knowledge on the environment and its relations, stimulating in the citizens the critical-reflexiva capacity, the responsible conscience and, above all, attitudes and commitment with the question. Thus, as process that is, the EA demands permanent and continued educative formation and action (BRAZIL, 2007). In this complicated educative process, that demands as many actions, it is necessary the communication between the pairs (Freire, 1975).

The not formal education perpassa half popular of communication. For in such a way, the radio communication, as one of the informal ways of education, makes of the radio an excellent vehicle of dissemination for such objective. This affirmation still more is supported by the fact of this instrument of social communication to be what it reaches more people in Brazil, being syntonized more than the television in different states of the federacy, as in So Paulo and the Cear (Bridge Son and Sponsorship, 2010). The TV reaches a great part of the population, at the same time, with the same message, however, the radio, with its simple message, direct and more distributed, it arrives much more the people of what the TV. This affirmation if coats with bigger meanings, when it is desired to deal with ambient problems more regionalizados, that is, next to daily and the reality to the listener.
