Essay Questions

66. (p. 5, 6) Describe all the parts of an information system.

An information system typically consists of five parts: people, procedures, software, hardware,

and data. 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.

Difficulty: Medium

67. (p. 6) Where would it be most relevant to use the term "data" and the term "information"?

Give an example of each.

Data are unprocessed facts, including text, numbers, images and sound. An example might be a

listing of all customer purchases at a bookstore over the last year. Information is processed data

that has been rendered usable with the help of various types of software. From the previous

example, you could derive information such as the addresses of customers who bought more

than $500 worth of books or the year's top ten horror novels.

Difficulty: Medium

68. (p. 8, 9) What is an operating system? Give two examples. Operating systems are software that make the computer function. It is the layer that connects the

hardware to the applications software. All programs that run on the computer do so in

coordination with the operating system. Mainly, operating systems are programs that coordinate

computer resources, provide an interface between the users and the computer, and run

applications. Some examples of operating systems are Windows 7 and Mac OS X.

Difficulty: Medium

69. (p. 9, 10) What is application software? Describe the two categories of the application

software.

Application software might be described as end user software. These programs can be

categorized as either basic or specialized applications. Basic applications are widely used in a

large number of careers. One of these basic applications is a browser to navigate, explore, and

find information on the Internet. One of the most widely used browsers is Microsoft's Internet

Explorer. Specialized applications include thousands of other programs that are more narrowly

focused on specific disciplines and occupations. Some of the best known are graphics, audio,

video, multimedia, Web authoring, and artificial intelligence programs.

Difficulty: Hard

70. (p. 10) What are the differences between a supercomputer and a mainframe computer?

Supercomputers are the most powerful type of computer. These machines are special

high-capacity computers used by very large organizations. Although mainframe computers are

not as powerful as supercomputers, mainframe computers are capable of great processing

speeds and data storage. For example, insurance companies use mainframes to process

information about millions of policyholders.

Difficulty: Medium

71. (p. 11) Describe the differences between minicomputers and microcomputers.

Minicomputers, also known as midrange computers, are refrigerator-sized machines.

Medium-sized companies or departments of large companies typically use them for specific

purposes. For example, production departments use minicomputers to monitor certain

manufacturing processes and assembly-line operations. Microcomputers are the least powerful,

yet the most widely used, type of computer. There are six types of microcomputers: desktop

computers, media centers, notebooks, netbooks, tablet PCs, and handheld computers.

Difficulty: Medium

72. (p. 11) Describe the different types of microcomputers with relevant examples.

There are six types of microcomputers: desktop computers, media centers, notebooks, netbooks,

tablet PCs, and handheld computers. Desktop computers are small enough to fit on top of or

alongside a desk yet are too big to carry around. Media centers blur the line between desktop

computers and dedicated entertainment devices. Notebooks, also called laptops, are portable,

lightweight, and fit into most briefcases. Netbooks are smaller, lighter, and less expensive than

notebooks. Tablet PCs convert handwriting to standard text that can be further processed by

programs such as a word processor. Handheld computers are the smallest microcomputers and

are designed to fit into the palm of one hand. Personal digital assistants (PDAs) and smartphones

are the most widely used handheld computer.

Difficulty: Hard

73. (p. 12) Explain what a system unit is.

The system unit is a container that houses most of the electronic components that make up a

computer system. Two important components of the system unit are the microprocessor and

memory. The microprocessor controls and manipulates data to produce information. Memory is a

holding area for data, instructions, and information. One type of memory, random-access

memory (RAM), holds the program and data that is currently being processed. This type of

memory is sometimes referred to as temporary storage because its contents will typically be lost

if the electrical power to the computer is disrupted.

Difficulty: Medium

74. (p. 12, 13) What is secondary storage? What is the difference between hard disks and

solid-state storage?

Unlike memory, secondary storage holds data and programs even after electrical power to the

computer system has been turned off. Hard disks are typically used to store programs and very

large data files. Using rigid metallic platters and read/write heads that move across the platters,

hard disks store and retrieve data using magnetic charges. In contrast, solid-state storage does

not have any moving parts. It is more reliable and requires less power than hard disks. Solid-state
