Introduction to programming principles languages
The document provides an overview of basic computer and programming fundamentals, including components of computer systems such as hardware, software, and the operating system. It explains the evolution of programming languages from machine language to fifth-generation languages and highlights the functionalities of different software types. Various programming terminologies and concepts related to programming languages are also discussed, such as programmers, programs, and the roles of language translators.

- 7. 1.1.1 Computer SystemEnvironment The Software's Computer process data under the control of sets of instructions called computer programs. Also called as software programs. There are two types of software which are operating system and application software
- 8. Operating system consistingof programs and data, that runs on computers, manages computer hardware resources, and provides common services for execution of various application software. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between application programs and the computer hardware Ex: LINUX, UNIX, MICROSOFT WINDOWS 1.1.1 Computer System Environment The Software's
- 9. Application software iscomputer software designed to help the user to perform singular or multiple related specific tasks. Ex: Microsoft office, Adobe Photoshop, Windows Media Player 1.1.1 Computer System Environment The Software's

- 15. st Generation Language (GL1) irst-generationlanguage was (and still is) machine language or the level of instructions and data that the processor is actually given to work on (which in conventional computers is a string of 0s and 1s). nstruct computers to perform their most elementary operations one at a time. xample of 1GL: 1.2.2 Various Categories Of Programming Language And Technology +1300042774 +1400593419 +1200274927
- 16. nd Generation Language econd-generation languageis assembler (sometimes called "assembly") language. typical 2GL instruction looks like this: n assembler converts the assembler language statements into machine language. 1.2.2 Various Categories Of Programming Language And Technology ADD 12,8
- 17. rd Generation Language hird-generation languageis a "high-level" programming language, such as PL/I, C, or Java. ava language statements look like this: 1.2.2 Various Categories Of Programming Language And Technology public boolean handleEvent (Event evt) { switch (evt.id) { case Event.ACTION_EVENT: { if ("Try me" .equald(evt.arg)) {
- 18. compiler converts thestatements of a specific high-level programming language into machine language. In the case of Java, the output is called byte code, which is converted into appropriate machine language by a Java virtual machine that runs as part of an operating system platform.) 3GL language requires a considerable amount of programming knowledge. 1.2.2 Various Categories Of Programming Language And Technology
- 19. th Generation Language ourth-generation languageis designed to be closer to natural language than a 3GL language. anguages for accessing databases are often described as 4GLs. 4GL language statement might look like this: EXTRACT ALL CUSTOMERS WHERE "PREVIOUS PURCHASES" TOTAL MORE THAN $1000 1.2.2 Various Categories Of Programming Language And Technology
- 20. GL Features: a) userfriendly b) portable and independent of operating systems c) usable by non-programmers d) having intelligent default options about what the user wants e) allowing the user to obtain results fasts using minimum requirement code generated with bug-free code from high-level expressions 1.2.2 Various Categories Of Programming Language And Technology
- 21. th Generation Language Fifth-generation languageis programming that uses a visual or graphical development interface to create source language that is usually compiled with a 3GL or 4GL language compiler. icrosoft, Borland, IBM, and other companies make 5GL visual programming products for developing applications in Java, for example. isual programming allows you to easily envision object-oriented programming class hierarchies and drag icons to assemble program components. 1.2.2 Various Categories Of Programming Language And Technology
- 22. 1.3 Fundamentals ofProgramming Language programming language is an artificial language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs that control the behavior of a machine and/or to express algorithms precisely.
- 23. 1.3.1 Terminologies inProgramming Language rogrammer is someone who writes computer software. he term of computer programmer can refer to a specialist in one area of computer programming or to a generalist who writes code for many kinds of software.
- 24. 1.3.1 Terminologies inProgramming Language rogram is a sequence of instructions written to perform a specified task with a computer.
- 25. 1.3.1 Terminologies inProgramming Language rogramming is the process of designing, writing, testing, debugging, and maintaining the source code of computer programs.
- 26. 1.3.2 Language Translator ssembler -Assembler for an assembly language, a computer program to translate between lower- level representations of computer programs. ompiler - A compiler is a computer program (or set of program) that transforms source code written in a computer language (the source language) into another computer language (the target language, often having a binary form known as object code). ranslator/ Interpreter - many high-level programming languages have the option of using an interpreter instead of a compiler.
