What is an operating system for a computer?
An operating system (OS) is the software used to run a computer. Windows is an example for a operating system. Apple designed the Mac OS to run more stable.

Benefits of Computer-Aided Manufacturing
While undesirable for factory workers, the ideal state of affairs for manufacturers is an entirely automated manufacturing process. In conjunction with computer-aided design, computer-aided manufacturing enables manufacturers to reduce the costs of producing goods by minimising the involvement of human operators.
In addition to lower running costs there are several additional benefits to using CAM software. By removing the need to translate CAD models into manufacturing instructions through paper drafts it enables manufactures to make quick alterations to the product design, feeding updated instructions to the machine tools and seeing instant results.
In addition, many CAM software packages have the ability to manage simple tasks such as the re-ordering of parts, further minimising human involvement. Though all numerical controlled machine tools have the ability to sense errors and automatically shut down, many can actually send a message to their human operators via mobile phones or e-mail, informing them of the problem and awaiting further instructions.
All in all, CAM software represents a continuation of the trend to make manufacturing entirely automated. While CAD removed the need to retain a team of drafters to design new products, CAM removes the need for skilled and unskilled factory workers. All of these developments result in lower operational costs, lower end product prices and increased profits for manufacturers.
Problems with Computer-Aided Manufacturing
Unfortunately, there are several limitations of computer-aided manufacturing. Obviously, setting up the infrastructure to begin with can be extremely expensive. Computer-aided manufacturing requires not only the numerical controlled machine tools themselves but also an extensive suite of CAD/CAM software and hardware to develop the design models and convert them into manufacturing instructions - as well as trained operatives to run them.
Additionally, the field of computer-aided management is fraught with inconsistency. While all numerical controlled machine tools operate using G-code, there is no universally used standard for the code itself. Since there is such a wide variety of machine tools that use the code it tends to be the case that manufacturers create their own bespoke codes to operate their machinery.
While this lack of standardisation may not be a problem in itself, it can become a problem when the time comes to convert 3D CAD designs into G-code. CAD systems tend to store data in their own proprietary format (in the same way that word processor applications do), so it can often be a challenge to transfer data from CAD to CAM software and then into whatever form of G-code the manufacturer employs.
Why do you think that Operating System are necessary in order for a computer to run effectively?
The OS (Operating System) ensures that all the software has access to the different resources it need to run successfully and controls the running and scheduling of all these processes and manages the share of the Central Processing Unit's processing time that is used by the different processes, making the computer run effictively.
The purpose of testing hardware prior to installing operating system?
The purpose of testing the hardware is very important before you install the operating system because is to make sure if your computer can handle the operating system with having any problems; like for example, slowing down, and constantly freezing up. Having the right hardware makes everything run smoothly and doing your tasks on the computer with ease. It is like putting premium lead into a unleaded gas tank of a car, the car won't be able to handle and may cause problems.

Is a decision support system a hardware or a software?
If its a decision to turn on, turn a fan, boot, that's hardware mixed with a little bt of software, A discision support program? Software.
What is process interaction in operating system?
Accepting input from a human. Interactive computer systems are programs that allow users to enter data or commands. Most popular programs, such as word processors and spreadsheet applications, are interactive.
Why is it a good idea to reformat and reinstall the operating system?
Reinstalling the operating system is a good idea when you have issues with it that cannot be solved in any other way. For example, if you have malware issues in your PC which have completely taken the operating system in control, then you may not be left with any other choice. A complete reinstall with formatting cleans up everything in the hard drive, gives you a fresh registry and makes you to feel more comfortable to work with.
However, reinstalling may not be a good idea in a lot of other circumstances. For a lot of issues that affect PC's performance, there are always quick solutions.
