Applications software, sometimes referred to as applications, or simply apps is software designed to carry out a specific task, for example, accounting software, office suites (sometimes referred to as productivity suites), engineering software or graphics software.
Applications are a distinct category of softwatre. They they differ from operating systems (used to run the computer), utilities (used to carry out maintenance tasks) and programming tools (used to write computer programs). Applications may come bundled with an operating system, but they are more often purchased separately. Some applications are available for a range of platforms while others are targeted on a specific platform.
There are numerous types of application software:
An office suite consists several related applications. These normally include word processing, spreadsheet, database and presentation software, but some suites add other applications.The applications in a suite normally have a similar user interface and can share data. Common office suites include Microsoft Office, iWork, Open Office and LibreOffice. We will look in more detail at installing and running Microsoft Office and LibreOffice later in the course.
Enterprise software caters for large-scale organisational requirements and covers areas like financial software, Customer Relationship Management (CRM), and supply chain management systems.
Security software is used to protect systems against external threats and includes anti-virus and anti-spyware programs and firewalls. We’ll also look at this area in more detail later.
