Types of Software

An Operating System

Step 1: The question asks what is REQUIRED for application software to work efficiently. Step 2: Application software always runs in the BACKGROUND of a system software, specifically the Operating System (OS). Step 3: Without an OS (like Windows), application software such as MS Word or a Media Player cannot run at all. Step 4: A Compiler is a translator for programming languages — it is not what application software needs to run. Step 5: A Text Editor and a Loader are other types of system software but they do not provide the platform for application software to operate. The Operating System

Spreadsheet

Step 1: The question asks about MS Excel 2019 and which category it belongs to. Step 2: A Spreadsheet is an application software used to work with TABULAR DATA (values in rows and columns), perform calculations, and represent data as charts and graphs. Step 3: MS Excel 2019 is the recently developed Spreadsheet software. Step 4: A Word Processor (MS Word 2019) is used to create letters, notices, and documents — not for tabular data calculations. Step 5: A Database Management System (MS Access 2019) is for organising data in files with different fields. MS Excel's row-column structure and calcu

Customised (Special Purpose) Application Software

Step 1: The key details in the question are: built SPECIFICALLY for ONE school, for only ONE type of task (school management), and NO other school can use the same copy. Step 2: Customised (Special Purpose) Application Software is designed exclusively for ONE organisation as per its specific requirements — it is tailor-made or bespoke software. Step 3: It is the sole property of the organisation and is protected under copyright or licence agreement. Step 4: General Purpose Application Software (like MS Word) is made for EVERYONE and serves MULTIPLE purposes — it is NOT specific to one organisa

Bespoke or Tailor-made Software

Step 1: The question asks for another name for Customised Software. Step 2: According to the chapter, Customised Software is also called 'Bespoke' or 'Tailor-made' software — because it is made to fit the exact needs of one organisation, just like a tailor makes a dress to fit one specific person. Step 3: Freeware refers to software available free of cost to anyone — it is NOT the same as customised software. Step 4: Open Source Software is software whose source code is freely available to everyone — again, NOT customised. Step 5: Utility Software is a system software that performs specific ma
