- 3. What Is Software ? Software is the collection of data, programs, procedures, routines and instructions that tell a computer or electronic device how to run, work and execute specific tasks. This is in contrast to hardware, which is the physical system and components that perform the work. It is just a set of instructions, written by code to understand computer. At the core of all software is logic and the principle of input > process > output. The output is what happens as a result. Your printer whirrs into life and the invoice pops out of the tray.

- 5. Application Software Application software is a software program or group of programs designed for end-users. Application Software
- 6. What is Application Software ? • Application software is a computer program that performs a specific function, be it educational, personal, or business. It is also known as an end-user program or a productivity program. • Application software is developed to assist you with a particular process that may be related to creativity, productivity, or better communication. • Application software programs are specific in their functionality and do the job that they are designed to do. Basic of Application Software
- 7. i. Presentation Software : Presentation is a type of application software that enables you to represent your thoughts and ideas with ease and clarity by using visual information. ii. Web Browsers : Web browsers are application software used to browse the internet for locating and retrieving data across the web. iii. Multimedia Software : Multimedia application software lets you create or record images, and create audio or video files. iv. Education and reference software :This application software, also termed as academic software, is specifically designed to facilitate learning of a particular subject. Types of Application Software
- 8. v. Graphics software : Graphics application software allows you to edit or make changes in visual data or images. vi. Spreadsheet Software : Spreadsheet application software is used to perform calculations. vii. Database Software : Database application software is used to create and manage a database. viii. Word processing software : Word processing application software is used to format and manipulate text, thus, creating memos, letters, faxes, and documents. ix. Simulation software : Simulation application software is used in the fields of military engineering, practical education in certain industries, machinery testing, industrial training, video games, etc. Types of Application
- 9. Freeware : As the very name indicates, it is available free of cost. You can download freeware application software from the Internet and use it without any fees. Shareware : This is distributed freely to the users on a trial basis, usually with a limited time offer. The users are expected to pay if they want to continue to use this application software. Open Source : This type of application software is available along with the source code that allows you to modify the software, and even add features to the software. These could either be free or paid. Moodle and Apache Web Server are examples of open-source application software. Closed Source : Most of the application software packages that you use belong to this category. These are usually chargeable and have intellectual property rights or patents over the source code. It usually comes with restricted use. Examples include Microsoft Windows, Adobe Flash Player, WinRAR, mac OS, etc Types Based on Sharability and Availability
- 10. System Software Systems software includes the programs that are dedicated to managing the computer itself, such as the operating system, file management utilities, and disk operating system (or DOS). System Software
- 11. The most important features of system software include : Fast Speed Difficult to Manipulate Written in Low Language Difficult to design Features of System Software Closeness to the System
- 12. The most important tasks performed by the operating system are 1. Memory Management: The OS keeps track of the primary memory and allocates the memory when a process requests it. 2. Processor Management: Allocates the main memory (RAM) to a process and de-allocates it when it is no longer required. 3. File Management: Allocates and de-allocates the resources and decides who gets the resources. 4. Security: Prevents unauthorized access to programs and data by means of passwords. 5. Error-detecting Aids: Production of dumps, traces, error messages, and other debugging and error- detecting methods. 6. Scheduling: The OS schedules process through its scheduling algorithms. Compiler : A compiler is a software that translates the code written in one language to some other language without changing the meaning of the program. The compiler is also said to make the target code efficient and optimized in terms of time and space. Interpreter : An interpreter is a computer program that directly executes, i.e. it performs instructions written in a programming or scripting language. Interpreter do not require the program to be previously compiled into a machine language program. An interpreter translates high-level instructions into an intermediate form, which is then executes. Assembler : An assembler is a program that converts assembly language into machine code. It takes the basic commands and operations and converts them into binary code specific to a type of processor.
- 13. Application Software Application software are designed to fulfil the requirements of the user for performing specific tasks. Application Software is specific purpose software. Application Software starts when the user begins, and it ends when the user stops it. Application software needs system software to run. System Software System software are designed to manage the resources of the system, like memory and process management, security, etc. The System Software is a general-purpose software. The System Software starts running when the system is powered on and runs until the system is powered off. System software are independent of the application software Difference
- 14. SDLC : Software Development Life Cycle ˟ It offers a basis for project planning, scheduling, and estimating ˟ Provides a framework for a standard set of activities and deliverables ˟ It is a mechanism for project tracking and control ˟ Increases visibility of project planning to all involved stakeholders of the development process ˟ Increased and enhance development speed ˟ Improved client relations ˟ Helps you to decrease project risk and project management plan overhead SDLC

- 16. WaterFall Model in SDLC The waterfall is a widely accepted SDLC model. In this approach, the whole process of the software development is divided into various phases of SDLC. In this SDLC model, the outcome of one phase acts as the input for the next phase. Incremental Model in SDLC The incremental model is not a separate model. It is essentially a series of waterfall cycles. The requirements are divided into groups at the start of the project. For each group, the SDLC model is followed to develop software. The SDLC life cycle process is repeated, with each release adding more functionality until all requirements are met. V-Model in SDLC In this type of SDLC model testing and the development, the phase is planned in parallel. So, there are verification phases of SDLC on the side and the validation phase on the other side. V-Model joins by Coding phase. SDLC Models
- 17. Agile Model In SDLC Agile methodology is a practice which promotes continue interaction of development and testing during the SDLC process of any project. In the Agile method, the entire project is divided into small incremental builds. All of these builds are provided in iterations, and each iteration lasts from one to three weeks. Spiral Model The spiral model is a risk-driven process model. This SDLC testing model helps the team to adopt elements of one or more process models like a waterfall, incremental, waterfall, etc. Big bang model Big bang model is focusing on all types of resources in software development and coding, with no or very little planning. The requirements are understood and implemented when they come. SDLC Models
