Data center

Data center
An operation engineer overseeing a network operations control room of a data center A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems. It generally includes redundant or backup power supplies, redundant data communications connections, environmental controls (e.g., air conditioning, fire suppression) and various security devices. Large data centers are industrial scale operations using as much electricity as a small town[1] and sometimes are a significant source of air pollution in the form of diesel exhaust.[2] History[edit] Data centers have their roots in the huge computer rooms of the early ages of the computing industry. The boom of data centers came during the dot-com bubble. With an increase in the uptake of cloud computing, business and government organizations are scrutinizing data centers to a higher degree in areas such as security, availability, environmental impact and adherence to standards.

Client-side scripting By viewing the file that contains the script, users may be able to see its source code. Many web authors learn how to write client-side scripts partly by examining the source code for other authors' scripts. Due to security restrictions, client-side scripts may not be allowed to access the user's computer beyond the web browser application. Techniques like ActiveX controls can be used to sidestep this restriction. Client-side scripting is not inherently unsafe.

Java applet A Java applet that was created as supplementary demonstration material for a scientific publication.[1] Using applet for nontrivial animation illustrating biophysical topic (randomly moving ions pass through voltage gates)[3] Using a Java applet for computation - intensive visualization of the Mandelbrot set[4] Sufficient running speed is also utilized in applets for playing nontrivial computer games like chess[5] NASA World Wind (open source) is a second generation applet[6] that makes heavy use of OpenGL and on-demand data downloading to provide a detailed 3D map of the world. Web access to the server console at the hardware level with the help of a Java applet Java applets run at very fast speeds comparable to, but generally slower than, other compiled languages such as C++.

ITIL-Checklists This set of ITIL templates (ITIL document templates) can be used as checklists for defining ITIL process outputs. The ITIL templates can also serve as guidelines which are helpful during process execution. During the process of updating the ITIL Process Map to ITIL V3 2011 Edition, we also aligned our set of free ITIL templates and checklists to ITIL 2011. There are now 102 checklists contained in our ITIL-2011-compliant Reference Process Model, and we make the most sought-after ITIL templates available for you in our ITIL Wiki. ITIL 2011 Templates The following ITIL 2011 templates were submitted to an official review by APM Group; they are thus officially ITIL® licensed. ITIL Service Strategy Templates ITIL Service Design Templates ITIL Service Transition Templates ITIL Service Operation Templates ITIL CSI Templates Most popular ITIL Templates These are the most sought-after, officially licensed ITIL 2011 templates and checklists: Incident Record Template → Go to template ...

The Growing Importance of Client Side Programming | Grafx Design of Tampa Web design and development is an ever-changing landscape with the core focus of attracting users. Whether those users are customers or subscribers, our goal as developers / designers is to captivate them and keep them on the site to do what we need them to do. We have seen the web trends shift from simple forms and store fronts to complex websites with many options (that often confuse users). Basically the web is trying to find a balance to keep users happy while still giving them all the tools to get what they need done. With faster servers and internet connections we can do a lot more with sites than ever before but this does not necessarily translate into better sites. This is where User Experience Design (UX) comes into play. Companies invest a lot of money in UX designers who can successfully orchestrate a web site or application to be both highly functional and highly usable and this is where client side programming is really taking off.

Web Services Description Language The Web Services Description Language (WSDL) is an XML-based interface description language that is used for describing the functionality offered by a web service. The acronym is also used for any specific WSDL description of a web service (also referred to as a WSDL file), which provides a machine-readable description of how the service can be called, what parameters it expects, and what data structures it returns. It thus serves a purpose that corresponds roughly to that of a method signature in a programming language. The current version of WSDL is WSDL 2.0. The meaning of the acronym has changed from version 1.1 where the D stood for Definition. Description[edit] Representation of concepts defined by WSDL 1.1 and WSDL 2.0 documents. The WSDL describes services as collections of network endpoints, or ports. Example WSDL file[edit] <? History[edit] WSDL 1.0 (Sept. 2000) was developed by IBM, Microsoft, and Ariba to describe Web Services for their SOAP toolkit. See also[edit] References[edit] : A Practical Approach to Configuration Management With the introduction of CMDB concepts and IT management frameworks a stronger emphasis has been placed on visibility of the configuration of an Organisations' overall IT infrastructure. Some organisations have invested heavily in attempting to harness this information platform, with varying degrees of success. The one common element is that the following principle is widely recognised " The implementation of a structured Configuration Management Practice can save some organisations millions of $$$ from their annual IT operating expenses". Modeling a business case to support this practice and projecting some real $ savings can be a difficult task. There is a vast quantity of information out there, but finding the bit that helps your situation is another thing altogether. Originally this site was focused strongly on only open source offerings and how open source software could solve many of the configuration management issues in todays IT environment.

Cascading Style Sheets CSS is designed primarily to enable the separation of document content from document presentation, including elements such as the layout, colors, and fonts.[1] This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple pages to share formatting, and reduce complexity and repetition in the structural content (such as by allowing for tableless web design). CSS can also allow the same markup page to be presented in different styles for different rendering methods, such as on-screen, in print, by voice (when read out by a speech-based browser or screen reader) and on Braille-based, tactile devices. It can also be used to allow the web page to display differently depending on the screen size or device on which it is being viewed. CSS specifies a priority scheme to determine which style rules apply if more than one rule matches against a particular element. Syntax[edit] Selector[edit] Use[edit]

File Transfer Protocol FTP is built on a client-server architecture and uses separate control and data connections between the client and the server.[1] FTP users may authenticate themselves using a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. For secure transmission that hides (encrypts) the username and password, and encrypts the content, FTP is often secured with SSL/TLS ("FTPS"). SSH File Transfer Protocol ("SFTP") is sometimes also used instead, but is technologically different. History[edit] The original specification for the File Transfer Protocol was written by Abhay Bhushan and published as RFC 114 on 16 April 1971. Protocol overview[edit] Communication and data transfer[edit] Illustration of starting a passive connection using port 21 The server responds over the control connection with three-digit status codes in ASCII with an optional text message.
