Question 1

List the various categories of application software.

Accepted Answer

The three major categories of application software are horizontal-market, vertical-market, and one-of-a-kind application software.
Horizontal-market application software provides capabilities that are common across all organizations and industries.Word processors, graphics programs, spreadsheets, and presentation programs are all horizontal-market application software.Examples of such software are Microsoft Word, Excel, and PowerPoint.Vertical-market application software serves the needs of a specific industry.Examples of such programs are those used by dental offices to schedule appointments and bill patients, those used by auto mechanics to keep track of customer data and customers' automobile repairs, and those used by parts warehouses to track inventory, purchases, and sales.Vertical applications usually can be altered or customized.One-of-a-kind application software is developed for a specific, unique need.The department of Internal Revenue Service (IRS)develops such software, for example, because it has needs no other organization has.

Question 3

Why are mobile systems important?

Accepted Answer

Mobile systems are information systems that support users in motion.Mobile systems users access the system from any place-at home, at work, in the car, on the bus, or at the beach-using any smart device, such as a smartphone, tablet, or PC.Mobile systems users move not only geographically, but also from device to device.The user who starts reading a book on an iPad on a bus, continues reading that book on a PC at work, and finishes it on Kindle Fire at home is mobile both geographically and across devices.The major elements in a mobile system are users in motion, mobile devices, wireless connectivity, and a cloud-based resource.A mobile device is a small, lightweight, power-conserving, computing device that is capable of wireless access.Almost all mobile devices have a display and some means for data entry.Mobile devices include smartphones, tablets, personal digital assistants, and small, light laptops.Desktop computers, Xboxes, and large, heavy, power-hungry laptops are not mobile devices.
