Servers of lodging of sites are computers kept for a company, generally in a unit called datacenter or center of data. The intention of a server is to store sites until somebody has access them e, after that to answer quickly to the navigator of the visitor with the content of the site. A server must be capable to answer at least some sets of ten, seno hundreds of order of each time. A server can comfortably receive some sites, this depends on an ample variety from factors, including the hardware of the server and the popularity of the sites. Exactly that the server has the hardware most expensive of the present time it will not be very useful, without the software that really makes the hard work.
The program-key of the server of site lodging web also is called proper servers, or daemons. The majority of the used servers for lodging web has, these types of servers executing software permanently: A ftp server – for upload of arquivosUm serving HTTP or Web – to supply to the archives of siteE-MAIL and serving server or doisUm of data base – to store essential information for the functioning of a site But it will be that the servers web, are necessary? Why we cannot simply execute our site from a computer in our proper house? Some reasons exist for which the servers are necessary. The majority of the ISPs (Suppliers of Services of Internet) specifically hinders that the people execute any type of services related with server of lodging of site in its nets. Who ignores that is tries to execute the server in the local computer, has its suspended or cancelled account. But, exactly that the ISPs allowed the use of these services, we have that to take in account the speed of upload of the connection. Although the connections of broad band estejo being each time faster, speeds of upload are generally about 10-20 times slower than the speed of download. When executing a server in the proper computer, the speed of upload would be determined directly by the total speed of download shared between all the users who they will be having access the site. Very probably megabits would be offered one or two, and exactly thus if the site to contain some images it could simultaneously be had access by few people.
A professional server of a supplier dehospedagem of sites, on the other hand, could have a so fast connection how much 10,000 megabits. A connection with this speed costs a richness. Considering that a supplier can offer space in the server with a connection of highest speed for a fraction of the price. Moreover, the majority of the suppliers of broad band is not ' ' confiveis' ' the sufficient to house a site. The question of the up-teams (time of the site online) would not be possible to offer to a time online ' ' digno' ' using serving common of broad band because these will be carrying through maintenances you continue or exactly it are of air for reason of some invasion. In summary, considering the price of a server of professional lodging currently, the prices of a good plan can cost from R$5,00, therefore it is very vantagosa this choice of what to above house a site in the proper computer for some described reasons.
