GUI

For example a windows GUI has start menus, a desktop and a cursor; these features of a GUI makes it easier for users to navigate instead of having to learn complex command buttons/languages. …show more content…
The operating system knows where all your files are kept which is in sectors in your hard disk and the application and the operating system interact with each other through the programming interface. When an application needs to retrieve or save data, it makes a call to the operating system's file system, which is in charge of opening, reading, writing and closing files. See API and file system.

Microeconomics Assignement 1

....Microeconomics Assignement 1 1. a. Define opportunity cost, and explain its importance in economics. (3 marks) Opportunity cost refers to what you must give up (trade off) to obtain some item. It represents the forgone opportunities. It is very important to all of us; it helps and guides our decisions in life. For every decision made, no matter the circumstances; work, school, business, life in general, we incurred a cost, the opportunity cost, what we must give up to obtain the chosen good. The opportunity cost of an item is the weight of another item from those that society have to trade off or give up in order to obtain it, that is the way that society allocates its scarce resources. ALSO, OPPORTUNITY COST IS VERY IMPORTANT FOR THE THEORY OF COMPARATIVE ADVANTAGE AND TRADE. -1 MARK. b.

...BACHELOR OF COMMERCE (B.COM.,) PAPER – 2.1 MANAGERIAL ECONOMICS UNIT – I CHAPTER - I SECTION - I Definition of Managerial Economics Managerial economics refers to those aspects of economics and its tools of analysis most relevant to the firm’s decision-making process. According to MeNair and Meriam, managerial economies consists of the use of economic models of thought to analyze business situations. Some writers consider managerial economics as the integration of economic theory with business practice for the purpose of facilitating decision-making and forward planning by management. The underlying idea of all these definitions is that managerial economics means economics applied in decision-making. So we may consider managerial economics as a special branch of economics bridging the gap between abstract theory and managerial practice. It may be pointed out here that effective decision-making at the firms’ level calls for a careful analysis of a choice between alternative courses of action. Economic theory offers a variety of concepts and analytical tools which can be of considerable assistance to the manager in his decision-making process. In fact actual problem-solving may require many skills and tools which are not available in the traditional economist’s. For example, knowledge of accounting and of statistical concepts and methods, which are not taught in economics, can help the analyses to apply more effectively the economic...
