WHAT IS A SOFTWARE A set of instructions that cause a computer to perform one or more tasks. The set of instructions is often called a program or‚ if the set is particularly large and complex‚ a system. Computers cannot do any useful work without instructions from software; thus a combination of software and hardware (the computer) is necessary to do any computerized work. A program must tell the computer each of a set of minuscule tasks to perform‚ in a framework of logic‚ such that the computer

Introduction Career in mechanical engineering involves grappling with various aspects of the technical and practical work. The job of a mechanical engineer involves widespread handling of machines and components which have a direct relation with power by producing it‚ transmitting it or even making use of power. The major concern of mechanical engineers is bent towards ways and mechanisms through which natural energy sources are converted into uses of practical nature. As part of their work‚ mechanical
