Operating System (OS): The most important program that runs on a computer is operating system. OS is the term that acts as an interface between the hardware and the user. OS does basic operations such as getting input from the keyboard, displaying output in the monitor and monitoring the files. It is responsible for the management to co-ordinate the activities on a computer system. The responsibilities of OS are bound to get higher when it comes to security, because it provides the access rights for users. Windows: Windows is one of the operating systems that develop new versions frequently. It is an aggregation of operating systems developed by Microsoft. It includes Graphical User Interface (GUI) that helps in displaying the required data on the desktop or monitor. It includes various features like hardware adaptability and interdependence, memory management, task management, access security and many others.

Hi-Volt Components You are the IT manager at Hi-Voltage Components, a medium-sized firm that makes specialized circuit boards. Hi-Voltage's largest customer, Green Industries, recently installed a computerized purchasing sys- tem. If Hi-Voltage connects to the purchasing system, Green Industries will be able to submit purchase orders electronically. Although Hi-Voltage has a computerized accounting system, that system is not capable of handling EDI. Tasks 1. What options does Hi-Voltage have for developing a system to connect with Green Industries' pur- chasing system? 2. What terms or concepts describe the proposed computer-to-computer relationship between Hi-Voltage and Green Industries? why not? 3. Would Hi-Voltage's proposed new system be a transaction processing system? Why or 4. Before Hi-Voltage makes a final decision, should the company consider an ERP system? Why or why not?

Consider the following expression in C: a/b > 0 && b/a > 0.What will be the result of evaluating this expression when a is zero? What will be the result when b is zero? Would it make sense to try to design a language in which this expression is guaranteed to evaluate to false when either a or b (but not both) is zero? Explain your answer
