Week 4: Clear

Application software presents programs that humans use on their computer to get things done. It is the software we interact with directly. Examples are Microsoft Word, Google Chrome, and Photoshop. The OS software differs from this in that it interacts with the computer's hardware to make the computer function. In other words, it is an indirect interaction. Examples include Windows XP & Vista, Mac OSX, and Snow Leopard. In addition, utility software maintains the computing environment. Examples are file management, spam-blocker, firewalls, and anti-virus. I think being able to differentiate between these three software types are crucial in the business world. Moreover, one of the easiest concepts to gain a grasp on is Horizontal vs. Vertical Applications.

Horizontal Applications are software programs that are used across different industries for many different uses by a multitude of people. They are general use programs that *span across* numerous industries (thus the name "horizontal" application). Examples include word processing, web browsing, and music software. Whereas Vertical Applications are programs that are designed to meet the specific needs of a business market. It meets the needs of a single industry. Usually pertains to enterprise class software which is what you would rely on to run a business. Examples include CRM (customer relations management) software, which keeps track of a customer's connection to a company in terms of his or her history, and Point-to-Sale software, which keeps track of inventory and supplies needed. Applications are vital when it comes to running a business. Thus knowing what kind of application is needed, can be done using a "needs analysis," can greatly benefit one's company in regards to efficiency and productivity.
