Extension models demonstrate "how the program is structured and organized" at the local level in order to fulfill a "set of objectives" (Seevers and Graham 2012, 239). The two paradigms offer a concise, all-encompassing approach to proactive and reactive programming. They provide a formal structure for organizing programs that include functions, subroutines, and modules.
Functionality can be divided into three main categories: functionality shared by all models; functionality unique to one model; and overlap between different models. Shared functionality includes things like the number of vehicles being sold and their general appearance. Unique functionality includes features such as air conditioning and vinyl seats. Overlap occurs when more than one feature is required by more than one model. For example, some models may require air conditioning while others don't, so these models would have an overlap between AC and non-AC vehicles. Models also have different levels of complexity which determine how many extensions will be needed to complete the vehicle. A simple model with few parts could use a single module while a complex model with numerous parts might need several modules or even a whole other paradigm to organize its code.
The three main types of extension models are line extension models, panel extension models, and stack extension models. Line extension models extend the body of a car by adding a new sheet of metal over the existing body.
The overarching goal of an extension program is to persuade individuals to modify their ways of life and earn a better livelihood. The presumption is that there is a need for change, and that if individuals are unaware, they must be made aware. As well as to build their requirements and encourage them to purchase Bt maize.
The assumption of extension is that people are ignorant, which means that they need to be informed about issues around them. It also means that they need to be educated about their rights, obligations, and available options so that they can make informed choices about what steps to take next. Finally, it assumes that people can be persuaded to change their behaviors for the better.
In conclusion, extension relies on people's needs, desires, and abilities to persuade them to act in accordance with good practices. These elements are used by extension agents to develop programs for different groups of listeners.
A software extension is a sort of computer program that is designed to supplement (add to) the capabilities of another computer program (known as the base program). It usually contains some additional instructions that the original program does not have. Those instructions can be executed by either the basic program or the extension. They can also communicate with each other.
The term "software extension" was first used in 1979 to describe an add-on package that could be installed on IBM PC clones by then-current standards. This extension added floating point arithmetic to the 8086 processor. Before this addition, only integer arithmetic was available. It is a common misconception that only operating systems need extensions. Any program can have extensions, which can increase their functionality in various ways. Extensions can provide new features, fix bugs, or even replace parts of the main program.
There are two types of software extensions: drivers and libraries. Drivers are programs that allow your hardware to work properly with your operating system. For example, a graphics driver allows you to use graphics cards' features such as multiple monitors, video cards, and printers. Libraries are collections of functions that can be used by several programs or even just one. Examples include standard library functions such as strcat and math library functions such as sqrt.
An extension programme is a written declaration that includes the four aspects listed below: objectives that the agent expects to achieve in the region within a specific time frame. This is frequently a one-year term to allow the agent to examine the program at the beginning of each agricultural year. The extension report should include a detailed description of the program, including its objectives and activities.
An extension agent is an employee of an organization that is not involved in agriculture or rural development who works with farmers by providing them with information on farming techniques, new products, and other issues related to their business.
Extension programs exist to provide services to farmers and farm businesses that they cannot get elsewhere. These services include teaching farmers how to use equipment more efficiently, advising them on which technologies will best suit their farms, and supplying them with market information. Extension agents also work to promote government programs that benefit farmers. For example, they may distribute brochures about loan programs or help farmers participate in federal research projects.
In addition to teaching farmers what tools are needed on the farm and how to use them, extension agents also talk with them about other issues such as quality control during food processing; pesticide safety; and livestock care and management. They also conduct surveys and collect data on farm practices so that they can make recommendations based on what others are doing successfully. In this way, extension agents help farmers improve their operations and therefore increase their productivity.
