Abstraction is a mechanism to' hide irrelevant details and represent only the essential features so that one can focus on important things at a time; It allows managing complex systems by concentrating on the essential features only. For example, while d
In any programming language, the data type defines which operations can safely be performed to create, transform and use the variable in another computation. Specifically, every piece of data has a type that tells the machine how to interpret its value. Thus, if a data type is astring, the ...
Software is used to automate tasks physically on hardware and virtually on digital systems The set of programs on which software is built contains a collection of procedures, routines, instructions, and data. The software takes inputs from the user, processes data, and then delivers the desired ...
An abstraction is a simplified description, or specification, of a system that focuses on some essential structure or behavior of a real-world or conceptual object. A good abstraction is one in which information that is significant to the user is emphasi
Virtualization is a technology that enables the creation of virtual environments from a single physical machine, allowing for more efficient use of resources by distributing them across computing environments. Using software, virtualization creates an abstraction layer over computer hardware, dividing a sing...
An API, or application programming interface, is a set of rules and protocols that allows applications to exchange data, perform actions, and interact in a well-documented way. When a request is made—for a weather update, say—the API processes the request, executes the necessary actions, an...
(customers) while maintaining logical separation and physical connectivity. In essence, a single instance of software can run on a single server and serve multiple tenants, ensuring that each tenant’s data is securely kept separate from others. Below, the image illustrates the distinctions between ...
