⑴. Explain the five parts of an information system. What part do people play in this system?

An information system typically consists of: people, procedures, software, hardware, data, and connectivity. Information systems are used by people in order to increase productivity. Procedures are rules or guidelines for people to follow when using software, hardware, and data. Software is a program that contains the step-by-step instructions that tell the computer how to do its work. Hardware consists of the physical equipment that processes the data to create information. Data consists of raw unprocessed facts, including text, numbers, images, and sounds. Almost all of today's computer systems add an additional part to the information system. This part, called connectivity, typically uses the Internet and allows users to greatly expand the capability and usefulness of their information systems.

⑵. What is system software? What kinds of programs are included in system software?

System software is “background” software that enables the application software to interact with the computer. System software consists of the operating system, utilities, device drivers, and language translators. It works with application software to handle the majority of technical details.

⑶. Define and compare basic and specialized application software.

- Describe some different types of basic applications. - Describe some types of specialized applications.

Basic or general-purpose applications are widely used in a large number of careers. One of these general-purpose applications is a browser to navigate, explore, and find information on the Internet. Other basic applications are word processors, spreadsheets, database management systems, and presentation graphics.

Specialized applications are programs that are narrowly focused on specific disciplines and occupations. Some of the best known are multimedia, Web authoring, graphics, virtual reality, and artificial intelligence.
