Document Summary

Low level languages are referred to machine languages or assembly languages. It is encoding of instructions in binary so that they can be directly executer by the computer. Computers can only execute programs written in low-level languages. High-level languages, such as python, c++ and java, have to be processed before they can run and this is a small- disadvantage, though there are a lot of advantages of using high-level language. It is easier to program, less time to write and easier to read. Portable (low-level have to be rewritten to run on another computer) Two kind of programs process high-to-low, which are interpreters: program that reads high-level program and executes it (does what the program says) and compilers: program that reads the program and translates it completely before the program starts running. The high-level program is called source code . The translated program is called object code or executable .
