Just in time(JIT) is a fast compiler.
Remember that when client system sends a request to server system,then the response is sent in two ways
1)static response(google page) using html
2)Dynamic response(ex:cricket score update information)using Applets
To send user(client system)response in the form of Webpage,applets program (in the form of bytecode) transferred from server to client system over the internet and executed using JIT(i.e converts bytecode to native code)
A webpage may contain number of applet programs to give different reponses(updated news,cricket score....)then to execute each program using JVM is time taking process.so,JIT is used to compile all applet programs at once to reduce response time.
