Programming Language
It is a kind of language, which consists of a set of instruction to provide a particular result as output. Categories:
- Machine Language:
Also known as machine code or object code. It is coded in the form of binary and hexadecimal numbers, which a computer can understand. - Assembly Language:
Also known as assembly code. It is a low-level language, which is often used by microprocessors and consists of symbolic representation of machine code. - High Level Language:
Also known as HLL. These are user friendly programming languages, like C, C++, JAVA, which are generally used by human operators or programmers to solve a given problem. They require compiling/interpreting. - System Language:
These languages are designed for writing system software, which requires a different approach when compared with application software. - Scripting Language:
These are HLL, which do not require any kind of compiling, like JavaScript.

| Scans the entire program and translates the whole program into machine language. | Scans one line at a time. No translation. |
| It takes more time to analyze the source code. | It takes less time to analyze the source code. |
| Execution time is short. | Execution time is long. |
| Stops only after scanning the whole program. Hence, debugging is hard. | Stops, when error is met. Hence, debugging is easy. |
| Used by C, C++. | Used by Python, Ruby. |
