HELLO! We are group 10 Lê Trường Giang Trần Trung Anh Nguyễn Chí Dũng Nguyễn Văn Linh TABLE OF CONTENTS Definition • Programming language is any set of rules that converts strings, or graphical program elements in the case of visual programming languages, to various kinds of machine code output • In simple terms, programming languages are the tools we use to write instructions for the computer to follow What are programming languages used for ? • Application Development – creation of programs that perform tasks • Artificial Intelligence (AI) – simulation of human intelligence in machines What are programming languages used for ? • Database Development – creation of databases which store data • Web Development – the work involved in developing a website for the Internet History Of Programming Language 1883: Ada Lovelace wrote the instructions for the Analytical Engine, the first computer program 1949: Assembly Language 1952: Autocode, the first compiled computer programming language 1972: C language (developed by Dennis Ritchie), the first high-level programming language 1991: Python (developed by Guido Van Rossum), a simplified computer language 1995: PHP (developed by Rasmus Lerdorf) for Web Development 2000: Microsoft developed C# as a combination of C++ and Visual Basic 500+ Is the number of programming languages in the computer world  Abstraction ▹ It refers to how detached or separated a language is from the core computer concepts and language ▹ Higher level language = More abstraction High abstraction Low abstraction More abstraction = Less details Low-level Programming Language Low-level Programming Language ▹ Very close to writing actual machine instructions ▹ Provides little or no abstraction ▹ Machine dependent Machine Language • Instructions in binary form • Can be directly understood by the computer without translating Assembly Language • • • Instructions using symbolic/mnemonic codes in English language Between Machine language and High-level languages The Assembler converts the assembly code into machine code Assembler Pros ▹ Very fast and efficient ▹ Complete control ▹ Great for OS/Firmware Cons ▹ Hard to read, write, debug ▹ Machine dependent ▹ Not commonly used High-level Programming Language High-level Programming Language ▹ Close to human languages ▹ Strong abstraction ▹ Highly compatible → Easy to use and understand Compiler & Interpreter ▹ Compiler: Converts entire program into Machine Code → Creates exe file before running ▹ Interpreter: Converts each line of code into Machine Code → Does not create exe file before running Compiler & Interpreter Pros ▹ Easy to write and debug ▹ Widely used ▹ Portable Cons ▹ Slower execution ▹ Low efficiency Summary Abstraction High-level Language Low-level Language User-friendly Machine-friendly Less memory efficient High memory efficient High-level Language Simple to comprehend It's easy to keep up with Difficult to comprehend Difficult to maintain It is compatible with all It is entirely dependent on operating systems the machine Assembly Language For translation, a compiler For translation, it will need or interpreter is required Machine Language an assembler It is commonly used in It is no longer widely used programming in programming ... programming language 1972: C language (developed by Dennis Ritchie), the first high-level programming language 1991: Python (developed by Guido Van Rossum), a simplified computer language 1995: PHP (developed... of programming languages in the computer world  Classification Programming Language Classification Low abstraction High abstraction Low-level Programming Language High-level Programming Language. .. a language is from the core computer concepts and language ▹ Higher level language = More abstraction High abstraction Low abstraction More abstraction = Less details Low-level Programming Language
