The Interactive Disassembler, more commonly known as simply IDA, is a commercial disassembler widely used for reverse engineering. It supports a variety of executable formats for different processors and operating systems. A disassembler is a computer program which translates machine language into assembly language, performing the inverse operation to that of an assembler. ... Reverse engineering (RE) is the process of taking something (a device, an electrical component, a software program, etc. ... An executable or executable file, in computer science, is a file whose contents are meant to be interpreted as a program by a computer. ... Intel 80486DX2 microprocessor in a ceramic PGA package A central processing unit (CPU), or sometimes simply processor, is the component in a digital computer that interprets instructions and processes data contained in software, like a brain in a human. ... In computing, an operating system (OS) is the system software responsible for the direct control and management of hardware and basic system operations. ...


Although IDA performs a large degree of automatic code analysis to a certain extent, leveraging cross-references between code sections, knowledge of parameters of API calls, and other information, it is focused on being interactive. A typical IDA user will begin with an automatically generated disassembly listing and then rename, annotate, or otherwise add information to the listing, until it becomes clear what it does, creating an effective reverse-engineering. API with 3 clients, using the Unified Modeling Language notation An application programming interface (API) is the interface that a computer system or application provides in order to allow requests for service to be made of it by other computer programs, and/or to allow data to be exchanged between...


Created as a shareware by Ilfak Guilfanov, it was later turned into a commercial product by DataRescue, a Belgian company, who currently maintains and supports an improved version called IDA Pro. Along with the Professional version, Datarescue has constantly made a freeware version available. Shareware is a marketing method for software, whereby a trial version is distributed in advance and without payment, as is common for proprietary software. ... Ilfak Guilfanov Ilfak Guilfanov (b. ... Freeware is computer software which is: Made available free of charge. ...


Ilfak is the main author of IDA (Interactive Disassembler Pro) and is arguably one of the best low-level Windows experts in the world.

disassembler: Definition and Much More from Answers.com (772 words)
A disassembler is a computer program which translates machine language into assembly language, performing the inverse operation to that of an assembler.
Disassembly, the output of a disassembler, is often formatted for human-readability rather than suitability for input to an assembler, making it principally a reverse-engineering tool.
Some disassemblers can infer useful names and comments; however, interactive disassemblers are able to successfully disassemble more programs than fully-automated disassemblers because human insight applied to the disassembly process parallels human creativity in the code writing process.
