What is RSS?

RSS stands for “really simple syndication,” or, depending on who you ask, “rich site summary.” At their heart they are just simple text files with basic updated information — news pieces, articles, that sort of thing. That stripped-down content is usually plugged into what is called a “feed reader” or an interface that quickly converts the RSS text files into a stream of the latest updates from around the web. 

As internet content became more complex, so did RSS files, which quickly adopted images, video, and more, but still in a stripped down format for easier loading and compatibility across all feed readers. Readers usually automatically update, so that they delivers the newest content right to your device. Basically, this approach allows internet users to create their own online feed filled with custom updates from the sites that they like to visit regularly.

What is an SSL Certificate?

An SSL Certificate (Secure Sockets Layer), also called a Digital Certificate, creates a secure link between a website and a visitor's browser. By ensuring that all data passed between the two remains private and secure, SSL encryption prevents hackers from stealing private information such as credit card numbers, names and addresses.

If you sell products or services on your website and accept credit cards online, you need an SSL Certificate for website security. If you don't sell online but want to add credibility to your website, a Site Confirm Seal may be sufficient.

What is URL Shortener?

URL shortening services are Web tools (or services) that allow you to provide a long URL to a specific webpage and obtain a much shorter URL from the service provider.

A URL shortener is a good option when you have a lengthy or unattractive URL that you want to share online in social media, instant messaging or even blogs and in email. In this Webopedia Quick Reference we look at how a typical online URL shortener works and offer tips and things to consider when using these redirection services.

What Is Streaming TV?

The success of streaming media is pretty recent, but the idea behind it has been around as long as people have. When someone talks to you, information travels toward you in the form of a sound wave. Your ears and brain decode this information, allowing you to understand it. This is also what happens when you watch TV or listen to the radio. Information travels to an electronic device in the form of a cable signal, a satellite signal or radio waves. The device decodes and displays the signal.

In streaming video and audio, the traveling information is a stream of data from a server. The decoder is a stand-alone player or a plugin that works as part of a Web browser. The server, information stream and decoder work together to let people watch live or prerecorded broadcasts.

What is WOW64?

64-bit is a CPU architecture that is capable of transferring 64-bits of data per clock cycle. More plainly, it's the amount of data your CPU can handle each time it processes information. You can think this architecture as a road that's 32 lanes wide; only 32 "vehicles" (bits of data) can go through an intersection at a time.

In more technical terms, 64-bit is referencing the width of the registers on a computer's microprocessor or the computer bus; sometimes called WOW64 and x64.

What is Java Web Start

Java Web Start software provides the power to launch full-featured applications with a single click. Users can download and launch applications, such as a complete spreadsheet program or an Internet chat client, without going through lengthy installation procedures.

With Java Web Start software, users can launch a Java application by clicking a link in a web page. The link points to a Java Network Launch Protocol (JNLP) file, which instructs Java Web Start software to download, cache, and run the application.

What is the jarsigner tool?

The next tool we'll look at is the jarsigner tool; this tool creates signed JAR files. The jarsigner tool uses the information in a keystore to look up information about a particular entity and uses that information either to sign or to verify a JAR file. 

The keystore that jarsigner uses is subject to the KeyStore class that has been installed into the virtual machine; if you have your own keystore implementation, jarsigner will be able to use it. Similarly, if you use the standard keystore implementation, but hold the keys in a file other than the default .keystorefile, jarsigner will allow you to use that other file as well.
