Java Virtual Machine is the name that Java Runtime Environment was known for a time.

Plenty of websites use Java technology to enrich visitors' experience, from bank websites to video game webpages, all require Java to function correctly.

Formerly known as Java Virtual Machine (JVM), the program was required to run web pages using Java. The JVM is now known as JRE (Java Runtime Environment) and can be installed on Windows, Mac, and Linux.

With JRE (Java Runtime Environment) and viewing web pages that use Java, you can run all those applications that have been developed in the Java programming language and that have the extension .jar.

Once you have installed the JRE, the program will take care of updating automatically, and this way, we will always have the latest version. There is a chance that your computer already comes with the pre-installed JRE, so if it is a very old version, we may have to uninstall it by hand to install the latest version subsequently.

JRE is virtually indispensable in all computers because sooner or later, we will use a program or website that you use Java, requiring us to have Java Runtime Environment installed.
