1. Hardware Aspects
A server is simply a computer system with hardware and special characteristics which are those that distinguish it from the home systems, the hardware support is more accurate and more complex configurations that allow better performance eg settings can accommodate 128 Microprocessors latest technology and multiple terabytes of RAM without being exaggerated at all these capabilities.
Other characteristics in terms of hardware, apart from its impressive capabilities to offer spectacular returns is what is known as hardware type “hotswap” or “hot swap” that allow us to replace damaged components without the need if you want to turn off the system to carry out maintenance.
2. Software Aspects
Besides all that need special hardware obviously developed software to control the hardware, use 100% and of course maintaining maximum stability.
The software responsible for controlling these machines so powerful is focused mainly to offer one or several services, these services may be designed to provide network functionality such as DHCP, or others, or in many cases provide functionality for users of the network, we see following are examples of services from a server:
Web Server: Provides or “serve” web pages, these are what we access through our ISP connections like this.
DNS Server: Responsible for resolving such claims, for example a name of a Web page to access the Internet and point your browser to “www.google.com” need a machine to translate that name to an IP address which will be the web server and not have to be the same server in any case.
File Server: These are typical of a company’s local network, though some are much more powerful than the measured capacities can accommodate exaBytes. These tend to store information necessary for network users to perform their work (in the case of a company) but we could say that any computer system that shares files on a network is doing the functions of a file server.
