Computer Servers - What Are They, And How Are They Used?

Computer servers are powerful machines designed to service more user than smaller machines, such as PCs. Computer servers are used in enterprises and organizations for high data storage capacity. Regular computer servers are standard in size for the convenience of maintenance.

Servers

Servers enable many computers to access data that is stored in the network. They are available in different sizes and shapes. Servers typically have high performance processors and contain hardware and software capable of handling large amounts of data. A computer system may operate to act as a single server or may enable a number of servers to operate independently. Network servers are often use for storage of information, communication, and to provide access to communication networks, including the Internet. There are many servers such as listed here.

"Rackmount servers" provide an effective way of storing a large number of servers, and thus storage capacity, in a relatively small space. They are typically mounted in vertical racks. "High density servers" designed to run critical applications requiring sufficient ventilation and cooling to ensure that the server maintains a high level of availability. These servers should also be secure from unintended and unauthorized access.

Software

Each server processing card may include software and hardware components that is necessary to perform. As follow: "Adware" Software throughout which advertisements are continually running while the software is in use.

"Patches" A fix for a software program where modifications are required to correct a weakness identified in the source code.

"Interactive Voice Response" is a software application that accepts a combination of voice telephone input and touch-tone keypad selection and provides appropriate responses in the form of voice, fax and e-mail. "OEM licence" Original manufacturer licence, that is supplied to software which is pre-installed onto a computer by the reseller prior to delivery, uaually as a bundle. There is a fixed maintenance window being introduced to remove the unpredictability of service disruptions and to provide you with the ability to install required hardware, software, and security upgrades on a regular basis.
