A virtual machine (VM) is a virtual environment which functions as a virtual computer system with its own CPU, memory, network interface, and storage, created on a physical hardware system. VMs are isolated from the rest of the system, and multiple VMs can exist on a single piece of hardware, like a server. That means, … Continue reading Virtual Machines

Asymptotic Notations and its properties
Asymptotic Notations Asymptotic notations are used to represent the complexities of algorithms for asymptotic analysis. These notations are mathematical tools to represent the complexities. There are three notations that are commonly used. Big Oh NotationBig Omega NotationBig Theta Notation Big Oh Notation Big-Oh (O) notation gives an upper bound for a function f(n) to within … Continue reading Asymptotic Notations and its properties
Spiral Model
Spiral model is one of the most important Software Development Life Cycle models, which provides support for Risk Handling. In its diagrammatic representation, it looks like a spiral with many loops. The exact number of loops of the spiral is unknown and can vary from project to project. Each loop of the spiral is called a Phase of … Continue reading Spiral Model
Operating System Generations
Operating Systems have evolved over the years. So, their evolution through the years can be mapped using generations of operating systems. There are four generations of operating systems. These can be described as follows − The First Generation ( 1945 - 1955 ): Vacuum Tubes and Plugboards Digital computers were not constructed until the second … Continue reading Operating System Generations
Multiprocessor Systems
A multiprocessor is a data processing system that can execute more than one program or more than one arithmetic operation simultaneously. It is also known as a multiprocessing system. Multiprocessor uses with more than one processor and is similar to multiprogramming that allows multiple threads to be used for a single procedure. The term ‘multiprocessor’ … Continue reading Multiprocessor Systems
Operating System Operations
An operating system is a construct that allows the user application programs to interact with the system hardware. Operating system by itself does not provide any function but it provides an atmosphere in which different applications and programs can do useful work. The major operations of the operating system are process management, memory management, device … Continue reading Operating System Operations
