Essays on Operating Systems

Interprocess communication (IPC) is a group of programming interfaces which enable a software developer or programmer to coordinate different tasks and activities among different program operations which execute simultaneously in the operating system. IPC enables a program to handle many user requests at the same time. An user request results in execution of multiple processes in the operating system. The processes must communicate with one other to carry out their tasks. The interfaces of IPC aids in communication,data exchange among the different processes. There are advantages and disadvantages present in every method of IPC. A single program can ...

An operating system forms the core of a computer in that it coordinates the processes of the computer, its memory, and all of the computer’s hardware and software. It likewise permits the user to connect with the computer even without prior knowledge of how to interpret the language of the computer. A computer without an operating system is non-functional. In most cases, there are some diverse computer programs functioning simultaneously, and they all must access the memory, storage, and the central processing unit (CPU) of the computer. The operating system harmonizes all the programs to make sure every ...

Introduction

Patents are useful for protecting the rights of inventors and innovators who create new technology. The patents provide protection for the idea and in return, the new invention is available to the public for relevant use. The validity of a patent is twenty years. The downside is that no one else can come up with the same idea for those twenty years. Other inventors can use the invention in their products without modifying the base product with a license provided by the patent holder. For example, if an inventor creates a car that runs on water, it will prevent ...

Introduction

Dittner & Rule (2011) describe virtualization as a methodology or framework of dividing the computer hardware’s resources into several execution environments, by utilizing the concepts or technologies, for example, complete or partial machine simulation, software and hardware partitioning, and time-sharing, among others. Virtualization is, thus, an abstraction of the resources of a computer hardware. As a software technology, virtualization facilitates the running of several operating systems on the similar server simultaneously (Cartwright, Mills, Langone, & Leibovici, 2014). In the contemporary information technology, there exist different forms of virtualization. The present paper delves into two of these forms, namely, server virtualization ...
