What means server, dedicated server and mainframe
By rmcml
SERVER:
Before we talk on dedicated servers, it should be a sense to know what is a server.
In computer terms, a server is a system (a computer for example) which are connected to multiple computers - called customers. This connection allows access to files or e-mail between the various devices. Is established, therefore, a connection client-server.
A server may be, for example, a set of computers, networked to other computers, and providing them some sort of service. Or may be even a particular program, or a set of disks for storing data or any other type of device, which is not necessarily a computer.
The evolution of companies that use computer networks, combined with an increase in Internet usage between users and professionals, or even among professionals, it was one of the reasons that led to the development and improvement of the servers and their technology. This trend has enabled the reduction in the use of mainframes.
MAINFRAME:
Mainframe is like a big computer, with a lot of processors, serving to support the main processors. Can work with large volumes of information and a great speed. Allows data processing of thousands of users who may be connected to it, either directly or via a network, always with an extreme level of security. A mainframe has the capacity to perform tasks requiring a lot of information, available from internal or external to your system, such as large database, for example, credit cards, bank accounts, airline tickets, among many others.
Banks and universities, are examples where you can find this type of equipment. They have the advantage of allowing the use of older programs and be compatible with other more recent programs.
PC servers and Unix servers, have been replacing the mainframe, since they have a very high cost, take up much space and require special conditions of refrigeration.
DEDICATED SERVER:
A dedicated server, also called a hosting server or dedicated server hosting is a set of systems with certain characteristics, configured for the type of function to perform, which can be provided to house files, emails, forums or pages Internet. Besides the high security and confidentiality of information, a dedicated server also allows a high performance management of all its contents.It also has high security, such as generators themselves, in case of power failure and skilled personnel for their maintenance. A dedicated server is always running and is connected to a high-speed connection to a company or a data center (data center). To him is always an ally of service management server itself, for the maintenance and supervision thereof.
Now there's several options for dedicated servers - simple for the User who owns a blog or a site or a large company or site with high traffic volume. These servers are hosted in data centers in different parts of the world and packages at different prices, depending on the user's need, both in terms of security, and at the amount of information the host. Anyone can have access to a dedicated server, by paying a monthly or annual fee, with access to housing of all information of a personal blog or files available constantly, securely and from anywhere in the world.
Anyone can set up your own server. But have their weaknesses, especially in terms of reliability, in terms of speed of download and upload files and also the level of performance.
A dedicated server may have a higher cost, if there is a need for a greater volume of traffic and greater security in the accommodation information. Justified its use in businesses that require servers with these features, as they always have their data stored and available 24 hours and a huge processing speed.
Previously, it was called a dedicated server to a server on a local network, which basically shared files and printers.
A dedicated server is always administered remotely and increasingly in a simple and accessible to every user. There are several tools that facilitate the management, such as phpMyAdmin, Webmin, among many others, available from a browser like Internet Explorer, for example.
