Most of the Selenium Testers are using Java for Selenium, next Python for Selenium, next C# for Selenium and remaining programming languages are less use.

Java has 3 important editions, 1) Java Standard Edition or Core Java, 2) Java Enterprise Edition or Advanced Java, 3) Java Micro Edition. Java Standard Edition or Core Java is enough for Selenium.

a. Selenium IDE (Integrated Environment) doesn’t support any programming, It is only record &playback tool.
b. Selenium Grid is only for Test Execution and it doesn’t support Test Design.
c. Selenium RC is out dated and removed from latest version/s for Selenium.

Selenium is a suite of Test Tools for automation, It is not a single tool like UFT, RFT and SilkTest, but we no need to use all Selenium Tools for Testing, using Selenium WebDriver only you can create & execute test cases.
