RAD can be defined as an adaptive software development approach that prioritizes prototyping and quick feedback rather than specific planning. This enables developers to make multiple iterations and updates quickly without having to start from scratch, thereby ensuring that the outcome is more quality-focused and aligns with the end users’ requirements. RAD focuses on the input-output source and destination of the information, delivery of projects in small pieces, and reuse of templates, tools, processes, and code.

RAD prototype modeling phases include:
• Business modeling
• Data modeling
• Process modeling
• Application generation
• Testing and turnover.

Advantages

i. The RAD model is flexible and adaptable to changes.
ii. It is useful in reducing the overall project risk.
iii. Reducing manual coding since code can be reused.
iv. Prototyping ensures fewer defects.
v. It is easier to transfer deliverables as scripts, high-level abstractions, and intermediate codes.
vi. Each RAD phase delivers the highest priority functionality to the client.
vii. Increase productivity in a short time with fewer people.

A modem refers to a device that converts data to a signal so it can be easily sent and received over a phone line, cable, or satellite as well as converts data between analog and digital formats in real time for two-way network communication. On the other hand, a multiplexer refers to a device that takes multiple analog signals and forwards the selected input into a single line and is used to increase the amount of data that can be transmitted over a network.

Internet of Things(IoT): IoT can be defined as a network of interrelated devices that connect and exchange data with other IoT devices and the cloud. The IoT devices are impendent with technology such as software and sensors and can include digital and mechanical machines and consumer objects.
Examples of IoT applications are connected wearables, cars, sensors in industrial plants, and collaborative robotics.

Information Value Chain(IVC): The Information Value Chain can be defined as the process of changing data to information, and using the information to make decisions and real-world actions that create /deliver value back into the real world(i.e. stakeholders).IVC’s goal is to create a competitive advantage for a firm by increasing efficiency and productivity while keeping costs reasonable.

The digital divide: The digital divide can be defined as the gap (technical and financial ability) between demographics and regions that have access to modern information and communications technology and those that don’t. It exists between developed and undeveloped/developing countries, young educated and older uneducated individuals, urban and rural populations,as well as between men and women. Other types include the access divide, the use divide, and the quality-of-age gap.

Workflow management software(WMS): WMS can be defined as a software application designed to set up and monitor a defined set of tasks along with their sequences.WMS provides a well-planned, structured, and centralized approach to managing business processes and helps in the reduction of manual efforts/resources involved and the automation of redundant tasks.

i. Boosts Student Engagement: Virtual reality classroom is equipped with adequate ways to make learning more engaging and communicative which helps in boosting student engagement.
ii. Experience-Based Learning: -VR provides experience-based learning by providing stimulated displays which makes the students feel like a part of the setup they are looking at.
iii. Virtual Field Trips: - Virtual reality can be a great opportunity to take the travel and tour experience without actually visiting the place, in a cost-friendly and time-saving manner.

i. A programming language must be simple, and easy to learn.
ii. It must be efficient hence easily convertible into a machine code and should also consume little memory space.
iii. It should be well structured and documented, thus suitable for the development of applications.
iv. It must provide the necessary tools for development, testing, debugging, and maintenance.
v. It should have the ability to handle complex structures efficiently (abstraction).
vi. It should be consistence in terms of semantics and syntax.
vii. It should have a single Integrated Development Environment (IDE).

i. The Operating System is responsible for the execution of all types of programs (i.e. user programs or system programs).

ii. The Operating System is responsible for making decisions regarding the storage of all types of data or files (i.e., floppy disk/hard disk/pen drive, etc.). The decides how the data should be manipulated and stored.

iii. The Operating System is responsible for handling all sorts of inputs, (i.e., from the keyboard, mouse, desktop, etc.) and does all interfacing of different types of peripheral devices (e.g. keyboard or mice) most appropriately regarding all kinds of Inputs and Outputs.
