The system software provides the infrastructure needed to run application software, allowing it to interface with the hardware of the computer system.Application Softwareconsists of the programs that perform tasks specific to the machine's general purpose. A computer used to maintain a store's inventory needs different software than a machine used by a mechanical engineer. Spreadsheet, database, desktop publishing, accounting, and program development software are all examples of application software.Software Hierarchy Application Software TypesSpreadsheets, web browser, accounting, etc.System Software TypesMicrosoft Windows, Linux, Mac OS X, DOS, etc.

Operating System (OS)is software that manages computer hardware and software resources and provides common services for computer programs

- performs basic tasks such as: file management, memory management, process

management, handling input and output, and controlling peripheral devices such as drives and printers Three of the most common operating systemsMicrosoft Windows, MacOs, and Linux Utility Softwareprovides additional functionality to the operating system

examples: software to compress or decompress data, play multimedia

presentations, and handle network communications Kernelis the internal part of an operating system (contains the basic functions of the OS) It's the underlying ode that runs the OS, allowing it to perform required tasks such as running applications and managing peripherals like memory and graphics Device Drivers (middleware)facilitate the communication of hardware and software

• A print driver needs to be installed if a user wants to send a document to the

printer. A Bluetooth headphone driver is necessary if a user wants to listen to music on Bluetooth headphones. Some device drivers are installed automatically, while others would need to be downloaded and installed from the manufacturers' sites.Software Licensingdefines the permissions, rights, and restrictions assigned to the person who purchases a copy of software Microsoft and Apple require you to purchase a license to install their operating systems, whether it is for personal or business use. Further, it is closed-source, meaning they do not permit anyone to modify their operating system code. The operating system is developed by Microsoft and Apple.Linux, on the other hand, is open-source and collaborators work together from around the world. Open-source systems allow individuals and organizations to open and modify the operating system's kernel, the heart of the operating system.What ways can software be package?Shareware, freeware, and public domain Sharewareis an application that can be installed as a trial limited by time and/or functionality.If the user decides to purchase the application or subscription, they then get the full functionality.Freewareis, as the term suggests, free. However, freeware and shareware are both protected by end-user license agreements (EULA) and copyright laws (where applicable).This is where freeware and shareware are differentiated from software in the public domain.

Public domain softwarehas no EULA and no intellectual property protections and is available for anyone to download and use at their own discretion.However, in the United States, a copyright gives an author of a software package the ability to prevent unauthorized duplication for at least 35 years.Five of the most commonly recognized computing disciplines Computer Engineering, Computer Science Software Engineering Information Systems Information Technology Computer Engineering (CE)focuses on the design of hardware systems and the software that makes them work.In addition to writing drivers for peripheral devices, such as keyboards and printers, computer engineering addresses the development of solutions that use computers embedded in other devices like alarm systems, refrigerators, and self- driving cars.Computer Science (CS)addresses the design and implementation of software with an emphasis on developing effective ways to solve computing problems and creating new ways to use computers.It encompasses a range of computing-related tasks such as robotics, artificial intelligence, augmented reality, and algorithms designed to solve problems.Software Engineering (SE)focuses on the development and maintenance of reliable and efficient software systems Information Systems (IS)integrates IT solutions meant to meet organizational business goals.This computing discipline addresses systems that generate, process, and distribute information and support organizational communication and collaboration, their design, and their implementation.Information Technology (IT)focuses more on the technology supporting information systems in an organization rather than the information residing on the systems or being communicated with them.In this sense, IT responds to the practical needs of the organization, including reliable and secure solutions that are appropriately maintained, updated, and replaced.Systems Administratora person who is responsible for providing techincal support for hardware and software issues end-users encounter, such as log-in issues Network Administratora person who is responsible for designing, planning, setting up, and maintaining an organization's network Database Administratora person who is responsible for installing and configuring databases. This position also fixes database errors and creates user accounts

Security Administratora person who is responsible for installing, administrating, and trouble shooting network security issues Web Administratoris responsible for troubleshooting error messages employees encounter when attempting to access their organization's website. The web administrator is also responsible for tracking, compiling, and analyzing website usage data. This role reports security breaches to appropriate personnel.Mobile Computingis the use of handheld devices, such as laptops, smartphones, and tablets Internet of Things (IoT)The system of interconnected devices Smart home devices, wearables, and connected cars are examples of IoT devices.These items rely heavily on sensors and network infrastructures to acquire and transmit data and possibly generate more new data.
