SYSTEM AND APPLICATION SOFTWARE SOFTWARE

Hardware All physical contents of computer are hardware.

This form is given to all electrical and mechanical devices attached to the computer for the purpose of input, process, and storage and output operations

Software Software is a general term used for computer

Programs. A computer program is a planned, step by step set of instructions that directs the computer what to do and how to do

What Is Hardware And Software

System Software◦ The programs directly related to the computer

hardware and perform tasks associated with controlling and utilizing computer hardware

Application Software◦ An application is a job or task a user wants to

accomplish through a computer.◦ Application software are programs that help a

user perform a specific job.

Types Of Software

How it is

How it is

System software is computer software designed to operate the computer hardware, to provide basic functionality, and to provide a platform for running application software.

System software includes device drivers, operating systems, servers, utilities, and window systems.

System software is responsible for managing a variety of independent hardware components, so that they can work together harmoniously.

System Software

System control programs ◦ controls the execution of programs, manage the storage &

processing resources of the computer & perform other management & monitoring function.

◦ The most important of these programs is the operating system. System support programs• provide routine service functions to the other computer

programs & computer users: E.g. Utilities, libraries,• Ex:Text editors, language translators such as BASIC interpreter

System Development Programs◦ They assists in the creation of computer programs.  Examples

of system development are –◦ programming language, language translations.

System Software

Application software are the software that are designed to satisfy a particular need of a particular environment.

All software prepared by us in the computer lab. Examples of application software are-student

record software, railway reservation software, income tax software, word processors etc.

Examples include enterprise software, accounting software, office suites, graphics software and media players.

Application software

1) Opera (Web Browser)2) Microsoft Word (Word Processing)3) Microsoft Excel (Spreadsheet software)5) MySQL (Database Software)6) Microsoft Powerpoint (Presentation Software)7) iTunes (Music / Sound Software)8) VLC Media Player (Audio / Video Software)

9) World of Warcraft (Game Software)10) Adobe Photoshop (Graphics Software)

Compiler

Compiler

Compiler: a program that translates an executable program in one language into an executable program in another language

Typically lowers the level of abstractionanalyzes and reasons about the program &

architecture

Compilers

Compilers “Compilation”

◦ Translation of a program written in a source language into a semantically equivalent program written in a target language

implement one or more compiler phases Scanner generators Parser generators Syntax-directed translation engines Automatic code generators Data-flow engines

Interpreter

Interpreter

Interpreter A computer program that executes

instructions written in a programming language and do not produces the executable file.

Interpreter: Checks the keywords of a program Taking one instruction at a time and convert it into machine

language before taking upon the next instruction.

Examples of interpreter based language: PHP, JavaScript, BASIC

Interpreter: a program that reads an executable program and produces the results of running that program

Interpreters: Convert a source program and execute it at the same time.

Interpreter “Interpretation”

Performing the operations implied by the source program

Assembler

Assembler

An assembler is a type of computer program that interprets software programs written in assembly language into machine language, code and instructions that can be executed by a computer.

An assembler enables software and application developers to access, operate and manage a computer's hardware architecture and components.

An assembler is sometimes referred to as the compiler of assembly language. It also provides the services of an interpreter.

Assembler

Assembler

To convert the assembly language into machine code.

Translate mnemonic operation codes to their machine language equivalents.

Assigning machine addresses to symbolic labels.

Working of Assembler• Programmer write a program using a sequence

of assemble instructions.• This sequence of assembler instructions, known

as the source code/source program, then specified to the assembler program when that program is started.

• It translates a source code into machine language.

• The output of the assembler program is called the object code or object program.
