Difference between high level and low level languages?

Answer 1

Low level languages bring you close to the machine, e.g. Assembly, or C. High level languages obfuscate more, so it makes life as a programmer easier. Consider:

Python, garbage collected.

C, not garbage collected.

Java, garbage collected.

And so forth.

C does has its uses, still: how could one make a hardware driver with a garbage collected language?

Answer 2

A low-level language is close to the machine language - the language the computer uses internally. This often requires several steps for a relatively simple task, such as adding two variables and storing the result in a third variable.

A high-level language usually requies much less instructions. The programmer is "shielded" from the specific machine language, and (in some cases), it is easier to "port" the program to other platforms (to other computers, or operating systems).

Answer 3

The main differences between high- and low-level programming languages:

High-Level (i.e: C, COBOL, Pascal, etc):

1. Syntax is user friendly.
2. Usually a huge library of functions.
3. Difficult or no access to low-level (hardware) functionality.
4. Few instructions do a lot of things.

Low-Level (i.e: Assembler, machine code):

1. Syntax is not usually user friendly.
2. Most of functionality usually has to be programmed by oneself.
3. Total control over hardware.
4. Total performance per se, as long as we know how to program efficiently.
5. You need more than just 1 instruction to perform some operations.
