  1. High level languages The instructions that tell a computer what to do are written in machine code. Machine code is a series of numbers, written in either binary or hexadecimal. Each number represents a different instruction. High level programming languages are languages that are close to the spoken and written language of the programmer.

    What is a high-level language?"High-level language" refers to the higher level of abstraction from machine language.

    Can a high level language be directly implemented by a computer?Alternatively, it is possible for a high-level language to be directly implemented by a computer – the computer directly executes the HLL code. This is known as a high-level language computer architecture – the computer architecture itself is designed to be targeted by a specific high-level language.

    What are the features of high level programming languages?Other features, such as string handling routines, object-oriented language features, and file input/output, may also be present. One thing to note about high-level programming languages is that these languages allow the programmer to be detached and separated from the machine.

    What was the first high level programming language?The first significantly widespread high-level language was Fortran, a machine-independent development of IBM's earlier Autocode systems. Algol, defined in 1958 and 1960 by committees of European and American computer scientists, introduced recursion as well as nested functions under lexical scope.

  4. https://en.wikipedia.org/wiki/High-level_language_computer_architecture

    There are a wide variety of systems under this heading. The most extreme example is a Directly Executed Language, where the instruction set architecture (ISA) of the computer equals the instructions of the HLL, and the source code is directly executable with minimal processing. In extreme cases, the only compiling needed is tokenizing the source code and feeding the tokens directly to the processor; this is found in stack-oriented programming languages running on a stac…
