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: 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

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.

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.
