Instructions are either in machine code
- or they are one to one with machine code
- Using mnemonic codes for operations
- Using labels for addresses of data
- Used for controlling the computer/close to hardware
- Allows direct manipulation of memory addresses
- Contains a code for the operation to be carried out...
- and a binary representation of the value to be manipulated/address of the value to be
manipulated.
- Different forms of addressing mentioned.
- Different forms of instruction: Arithmetic/Jump/Control

Low level programming language is a language that is not very abstracted from hardware layer.
Programming in low level languages usually requires manual memory management, use of pointers, and in case of assembler - CPU instructions themselves.
Medium level programming language,it lies between the low level programming language n low level programming language. In this king of programming language mnemonics(add,sub,div,sub) are used to code the operations. It's also called assembly level language. This languages are machine dependent it means that the assembly level language programming need to help understanding of the machine's internal organisation to write the programmes.
low level language is machine language which are not understandable by the programmer or say user
this is in the form of 0's & 1's
totally machine dependable
vary from computer to computer.
not portable not pass from one computer to another
Very close to machine code;
so very fast execution is achieved.
Difficult for human being to follow.
Machine and symbolic languages are considered as low-level programming languages and the statement written using language similar to English are termed as high-level programming language.
It's a "low level" language because it works at the machine level, while higher level languages are built on top of it.
Three type of languages High level Mid level Low level
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.
I takes a big knowledge about that compiler. The programmer should be well educated person to do with this 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.
