Konana's Model (from information systems/MIS contexts) is a layered framework illustrating the interdependent "ecosystem" of software and hardware technologies, typically starting with hardware at the base, followed by operating system, middleware/database management systems, enterprise systems/applications, and user/consumer applications on top—showing how each layer relies on the ones below for functionality and strategy.

A user interface (UI) is the point of interaction between a user and a computer/system; a graphical user interface (GUI) uses visual elements like icons, windows, menus, and pointers (e.g., mouse clicks) for intuitive interaction, as opposed to text-based command-line interfaces.

Hosted software (also SaaS or cloud-based) is applications delivered over the internet by a third-party provider, with users accessing via web browsers and data stored remotely (no local installation needed).
"What Is Hosted Software?" TechTarget, www.techtarget.com/searchcloudcomputing/definition/hosted-software. Accessed 22 Mar. 2026.
Local software (on-premises or installed software) is applications installed and run directly on a user's device or local servers, with data stored locally (contrasts with hosted/cloud models).

1. A student runs a small online thrift shop and tracks sales using spreadsheets. As orders increase, she installs software that stores all customer orders, allows her to search past purchases, and updates inventory automatically. She can now quickly find any order and update records without errors. Which concept BEST describes the role of this software in her business?
2. A campus organization uses one tool to track finances, another for member lists, and another for event sign-ups. Data is often inconsistent across systems, causing confusion. They adopt a new system that combines all functions into one platform with a shared database. Which system BEST explains this solution?
3. A student builds a mobile app and wants it to work across different devices and operating systems. Instead of writing separate code for each system, they use a layer of software that allows different applications and systems to communicate and share data easily. Which concept BEST describes this layer of software?
4. A student team is deciding whether to build their project using open-source tools or proprietary software. They choose open-source software so they can modify the code and customize features without restrictions. However, they know this may require more technical effort. Which concept BEST explains the benefit they are prioritizing?
5. A startup launches a web-based tool that students can access through a browser without installing anything. All data is stored on remote servers, and updates happen automatically without user action. The company charges a monthly subscription fee. Which concept BEST describes this software model?
