    Assembly Language

    A low-level programming language that uses symbolic instructions directly related to machine code.

    Characteristics of 2GL

    Assembly language is machine dependent, efficient, easier to write than machine language, but harder to understand than high-level languages.

    High-Level Programming Language

    A programming language that is machine independent, uses abstraction with variables, functions, and is readable by humans.

    Categories of High-Level Languages

    Five main groups: 3GL, 4GL, OOP, 5GL, and Scripting Languages, each evolving for different programming needs.

    Study Notes

    Introduction to Programming Language

    • Programming languages act as a vocabulary and set of grammatical rules to instruct computers for specific tasks
    • Different programming languages each possess a unique set of keywords (words understood by the language) and a specific syntax (grammar) to structure program instructions

    Syntax

    • Syntax refers to the spelling and grammar in a programming language
    • Each programming language defines its own syntactical rules to determine the acceptable combination of words the computer understands
    • Text-based languages utilize sequences of characters
    • Visual languages rely on the spatial arrangement and connections of symbols

    Example of a program code (small basic)

    • TextWindow.Writeline("enter the Temperature in fahrenheit ")
    • fahr = TextWindow.ReadNumber()
    • celsius = (5 * (fahr - 32) / 9)
    • TextWindow.WriteLine("This Temperature in celcius is " + celsius +" degrees")
    • This code example demonstrates a small basic program for converting the temperature from Fahrenheit to Celsius

    Levels of programming languages

    • Programming languages are categorized into machine language (1GL), assembly language (2GL), third-generation language (3GL), fourth-generation language (4GL), and natural language
    • Machine and assembly languages are low-level languages
    • Third-, fourth-, and natural languages are high-level languages

    Machine language - First Generation Language (1GL)

    • Machine language utilizes 1s and 0s (binary code) understandable by computers
    • The main drawback of using direct machine code is the high possibility of mistakes and difficulty in identifying errors

    Characteristics of 1GL

    • Fast execution due to the direct understanding by the computer hardware
    • Difficult to interpret, requiring a reference manual
    • Error-prone in terms of sequence and value assignments in the code
    • Machine dependent
    • Complexity of programs increases the difficulty of coding

    Assembly language - Second Generation Language (2GL)

    • Mnemonic codes (abbreviated English words) or short codes are used in assembly language, these codes indicate their functions
    • Codes represent operations, memory addresses, and storage registers within the computer

    Example of assembly language

    • LDA A, 20 : loads accumulator A with the value 20
    • ADD A, 10 : adds 10 to the value in accumulator A
    • STO B, A : stores the value in accumulator A into register B
    • NOP: no operation

    Characteristics of 2GL

    • Machine-dependent
    • Faster and more efficient than 1GL
    • Requires translation into machine code using assemblers
    • Easier to code than 1GL but still challenging to understand

    High-level programming languages

    • High-level programming languages are machine-independent, utilizing variables, objects, Boolean expressions, and similar constructs like functions, loops, arrays
    • These languages are categorized into: third-generation languages (3GL), fourth-generation languages (4GL), object-oriented programming languages (OOP), fifth-generation languages (5GL), and scripting languages

    Characteristics of high-level languages

    • Machine-independent
    • User-friendly and easy to learn
    • Easy debugging for programs
    • Higher programmer creativity and productivity
    • Slower execution speed compared to low-level languages
    • Requires translation to machine code by compilers/interpreters

    Major high-level programming languages

    • FORTRAN, COBOL, RPG, BASIC, Pascal, C, Ada, JavaScript, Python

    Language Translators

    • System programs that convert assembly/high-level languages to machine languages
    • Crucial for computers to understand programming instructions

    Source code

    • Program codes of high-level/assembly languages created by programmers in specialized editor tools
    • Source code requires converting into machine-readable form (object code)

    Object code

    • Program code in machine-readable form (translated source code)

    Assemblers and Compilers and Interpreters

    • Programs that translate high-level languages into machine code
    • Compilers translate the complete source code into machine code once to run the program
    • Interpreters translate and execute one statement in the source code at a time before moving to the next statement

    Interpreters

    • Interpreters translate each source code statement individually and execute each instruction in turn
    • Slower execution compared to compilers due to single-statement processing

    Assemblers

    • Translate assembly language into machine code
    • Recognize symbolic names for operations in assembly language and replace them with corresponding machine code

    Defining the problem

    • Problem definitions should be unambiguous, clear, and have one specific meaning
    • Examples of good problems:
      • Calculating the price of an item after a 10% discount
      • Converting Celsius temperature to Fahrenheit
      • Computing the average rainfall for May in a certain area

    Input and storage instructions

    • Instructions used by the computer to accept data
    • Words like 'Enter', 'Input', and 'Read' denote the data requirements for the computer

    Processing instructions

    • Instructions manipulating input data using mathematical operations (addition, subtraction, multiplication, division), loops, selection, and comparison
    • Often include commands and constructs (e.g., IF-THEN)

    Python Programming Language

    • An open-source, high-level, interpreted, dynamic programming language
    • Relatively easy to learn and use
    • Extensive libraries are beneficial
    • Flexible, usable as add-ons for highly customizable programs
    • Cross-platform compatible
    • High software quality
    • Strongly and dynamically typed data types
    • Embedded easily into applications
