Low Level languages are closest to computer hardware ,As they designed for specific computer architecture , they are said to be machine oriented. Low level languages can be further cathegorized as Machine language & Assembly Language .A '''low-level programming language''' is a [[programming language]] that provides little or no [[Abstraction (computer science)|abstraction]] from a computer's [[instruction set architecture]]—commands or functions in the language map that are structurally similar to processor's instructions. Generally, this refers to either [[machine code]] or [[assembly language]]. Because of the low (hence the word) abstraction between the language and machine language, low-level languages are sometimes described as being "close to the hardware". Programs written in low-level languages tend to be relatively [[Software portability|non-portable]], due to being optimized for a certain type of system architecture. Example : 0100011 Such number(Codes) are called low-level languages
Low-level languages can convert to machine code without a compiler or interpreter – [[second-generation programming language]]s use a simpler processor called an [[Assembly language#Assemble|assembler]] – and the resulting code runs directly on the processor. A program written in a low-level language can be made to run very quickly, with a small [[memory footprint]]. An equivalent program in a [[high-level language]] can be less efficient and use more memory. Low-level languages are simple, but considered difficult to use, due to numerous technical details that the programmer must remember. By comparison, a [[high-level programming language]] isolates execution semantics of a computer architecture from the specification of the program, which simplifies development.
