What is the difference between JSP and servlet?
Servlets are faster as compared to JSP, as they have a short response time. JSP is slower than Servlets, as the first step in the JSP lifecycle is the conversion of JSP to Java code and then the compilation of the code. Servlets are Java-based codes. JSP are HTML-based codes.

- You need a JRE(Java Runtime Environment) on the server to run servlets.
