What is a computer program?
A computer program is a series of instructions, whereas the instructions are the tasks that need to be performed. Hence a computer program is a collection of tasks that a computer needs to work upon. Series of instructions tell the computer what to do next.

As Computer is unable to understand human language, so we need translation to translate human language into computer understandable language that is in
binary language.

There are two types of translators

• Interpreter – Translate the instructions line by line 

Pros – Easy to debug the program

Cons – execution time is more.

• Compiler – Translate whole the instructions at a time.

Pros – Difficult to debug the program.
Cons – execution time is less.

What is a Programming Language?
Programming Language is a way to give instruction to the computer.
Integrated Development Environment (IDE)- is an environment with protocols to write a computer
program. It has many built-in functions to perform a specific task.

There are two types of Programming Languages

High-Level Language (HLL) – It is closer to human language.
Ex- C, C++, Python, et cetera.
Low-Level language (LLL) – It contains the basic instructions that can be recognized by a computer. The two common types of LLL is

• Machine Language
• Assembly Language.

 

Language R is a interpreter language. The code is being run line-by-line or batch of line executed in the sequence
