What are The Three Important Parts Of Unix Operating System‚ Explain Them? Answer: UNIX is an operating system which was first developed in the 1960s‚ and has been under constant development ever since. It is a stable‚ multi-user‚ multi-tasking system for servers‚ desktops and laptops. The UNIX operating system is made up of three parts; the kernel‚ the shell and the utilities (programs). THE KERNEL: The kernel of UNIX is the hub of the operating system: it allocates time and memory to programs

SHORTEST PATH ALGORITHM Faculty of Computer Science & Information system ABSTRACT Dijkstra Algorithm is utilized to compute shortest path in a network. It is essential to explain the different types of connected‚ directed and weighted graphs. Tree is also discussed with the help of graph. Dijkstra shortest path is shown and described with the example. Pseudo code and algorithm are also included along with their efficiency and applications. The different aspects of related algorithms were discussed

1. Introduction to Operating System:- Computer is a somewhat complex machine. The world has become accustomed to so many choices. One of the major choices in the modern era is the “Operating System (OS)”. Operating systems are the central software component to any computer. The main brands of operating system are; Windows Mac OS‚ Sun Solaris‚ UNIX‚ DOS and Linux. Each brand has its own take on what makes up an operating system. Windows is the most commonly used operating system around the world

OPERATING A FLEET OF ELECTRIC TAXIS ´ ´ BERNAT GACIAS AND FREDERIC MEUNIER Abstract. The deployment of electric taxi fleets is highly desirable from a sustainable point of view. Nevertheless‚ the weak autonomy of this kind of vehicles requires a careful operation. The way of managing such a fleet and the question of locating charging terminals for the vehicles are addressed in this paper. Methods for dealing with these tasks are proposed and their efficiency is proved through simulations. 1. Introduction
