Low level languages expose the internals of a computer's processor and allow you to take advantage of the power of that processor. Every processor has an assembler which allows you to code directly the machine language processed by the processor. This is the lowest level language available, however, the downside is that you are stuck producing code for only one processor and it will take a long time to write any significant program.
The next higher level language will be things like C, which are compiled fairly efficiently down to the machine level. C being higher level can be written and supported by many processors out there. It takes less C code to write a significant program than assembler.
The higher the level of a language the less code that is necessary to write a significant program, however, these programs are no longer efficient in terms of the amount of machine language generated. These programs often run slower and require large amounts of code to do simple things; this is counterbalanced by the ability to get complex things done with very little code. Many higher level languages are called 4GL for 4th generation languages.
A quantitative definition of 4GL has been set by Capers Jones, as part of his work on function point analysis. Jones defines the various generations of programming languages in terms of developer productivity, measured in function points per staff-month. A 4GL is defined as a language that supports 12-20 function points per staff month. This correlates with about 16-27 lines of code per function point implemented in a 4GL.

How many scripting languages are there?
Three type of languages High level Mid level Low level
How many level computer languages?
Languages are usually classified at two levels, low level programming and high level programming, although some experts also make a distinction of very high level languages and very low level languages. So, depending on who you ask, there are either two, three, or four. The most common set is probably three: low, high, and very high.
What are the classifications of programming languages according to each level?
high level and low level
What are the 2 levels of computer science program languages?
High-level and low-level.
Why say that 'c' is high level language?
Well, there are only two categories: low- and high-level languages. Machine code and Assembly are low-level, everything else is high-level.
What are low-level languages?
Low-level languages are one of two major types of programming languages. They are more similar to machine language, which is the language that computers understand directly; as opposed to high-level languages which are similar to English as humans speak.
What are examples of high lavel language?
The term high-level refers to the amount of abstraction between the code you write and the native language of the machine. Low-level code is a symbolic code that maps 1:1 with the machine code, thus assembly is a low-level language. All other languages that employ a compiler or interpreter to create the machine code are considered high level languages. However, C and C++ are examples of high-level languages that also allow low-level programming, and are often called mid-level languages for that reason.
What is the difference between high level and low level programming?
High level languages are easier for humans to read and program in. They are usually machine independent, and most have a wide variety of programming libraries available for common functions. Low level languages are usually machine specific, such as assembly languages. They lack programming libraries.
What is the program to convert Assembly level language to Higher level language?
There is no such program. Low level languages cannot be converted to high level languages. It's one-way only.
What are some high level languages?
Some high-level programming languages include Java, Python, C++, and C#. These languages are designed to be easier to read and write compared to low-level languages, making them more accessible for developers.
Why Low level languages are called Low level?
It's a "low level" language because it works at the machine level, while higher level languages are built on top of it.
What are necessary condition for programming language to be considered as high level language?
It mustn't be Assembly (or machine code). Unlike low-level languages, high-level programming languages may use natural language elements (easy syntax), be more user-friendly, have simple keywords, and other concepts that deem it easier to utilize than low-level languages.
