Information &

Computer Systems

Part I

108-15

• Explain the five parts of an information system: people, procedures, software, hardware, and data.

• Distinguish between system software and application software.

• Discuss the three kinds of system software programs.

• Distinguish between basic and specialized application software.

• Identify the four types of computers and the four type of microcomputers.

Learning Objectives

108-16

• Describe the different types of computer hardware including the system unit, input, output, storage, and communication devices.

• Define data and describe document, worksheet, database, and presentation files.

• Explain computer connectivity, the wireless revolution, and the Internet.

Learning Objectives

1-17

Introduction

• Computer competency refers to acquiring computer-related skills

• Microcomputers are common tools in all areas of life• New forms of learning have developed• New ways to communicate, to find people with

similar interests, and to buy goods are available.

Five Parts of an Information System

1. People

2. Procedures

3. Software

4. Hardware

5. Data

Page 4

1-19

People

• Most important part of any system• Contact is …

– Direct– Indirect

• Computer uses– Business & Entertainment– Education & Medicine

Page 6

1-20

People

• People are the most important part of an information system

• Our lives are touched everyday by computers- many time the contact is direct and obvious, such as creating documents using a word processing program or when connecting to the internet. Other times, it isn’t as obvious and is much more indirect as shown in a couple of the pictures

• Some examples are: ???

Page 6

1-21

Software

• Another name for programs• Softwares are instructions that tell the computer how to

process data into the form you want• Two major kinds of software

– System Software– Application Software

Page 7

1-22

System Software

• A collection of programs-not a single program• Enables the application software to interact with the

hardware• “Background software” that helps the computer

manage its own resources

Operating system (Windows 7, Linux, Mac...) Utilities (Virus programs...) Performs tasks related to managing computer resources

Device drives (Printer driver...)

1-23

Application Software

• End-user software: these are the types of programs you have to know to be considered computer competent

An example of a basic application is a browser to navigate, explore and find information on the Internet• Two major categories–Basic Application or General purpose•Specialized applications: Narrow focus on specific disciplines and occupations

Page 9

1-24

Application Software

• End-user software• Two major categories

– Basic Application or General purpose– Specialized applications

Hardware - Types of Computers

• Supercomputers• Mainframe computers• Minicomputers (also

known as mid-range

computers)• Microcomputers

Page 10

1-26

Hardware - Types of Computers

• Supercomputers – the most powerful; special high-capacity computers used in very large corporations

• Mainframe computers – are capable of great processing speed and data storage; occupy specially wired, air-conditioned rooms; insurance companies use to process information about millions of policyholders

Page 10

1-27

Hardware - Types of Computers

• Minicomputers - known as midrange computers (key term), are refrigerator sized machines used in medium sized companies or departments in large companies

• Microcomputers

Page 10

1-28

Microcomputer Types

• Desktop

• Notebook or laptop

• Tablet PC

• Handheld • Palm computers• Personal digital assistants (PDA)

Page 11

1-29

Desktop Computers

• Desktop computers are small enough to fit on top of or alongside a desk yet are too big to carry around

• Small but not a laptop

Return

Page 11

1-30

Notebook or Laptop Computers

• Notebook computers, also known as laptop computers, are portable, lightweight, and fit into most briefcases

Return

Page 11

1-31

Tablet PC

• A tablet PC is a type of notebook computer that accepts your handwriting. This input is digitized and converted to standard text that can be further processed by programs such as a word processor.

ReturnPage 11

1-32

Handheld

• Are the smallest and are also known as palm computers. These systems typically combine pen input, writing recognition, personal organizational tools, and communications capabilities.

• Personal digital assistants (PDA’s) are the most widely used handheldcomputer.

Page 11

1-33

Microcomputer Hardware

• Four basic categories of equipment:– System Unit– Input/Output– Secondary Storage– Communication

Page 11

1-34

System Unit

• Two important components– Microprocessor– Memory

Page 12

Return

• The microprocessor controls and manipulates data to produce information

• System Unit is the container that houses most of the electronic components that make up a computer system.

1-35

System Unit• Two important components

– Microprocessor– Memory

Page 12

Return

• Memory is sometimes referred to as temporary storage because its contents will typically be lost if the electrical power to the computer is disrupted

• Memory holds data and program instructions for processing the data. It also holds the processed information before it is output

1-36

Input/Output Devices

• Common input devices are the keyboard and the mouse

• Common output devices are printers and monitors

Page 12

Return

1-37

Secondary Storage

Page 13

Return

• Unlike memory, secondary storage holds data and programs even if electrical power is not available

• The most important types of secondary media are floppy, hard, and optical disks

1-38

Secondary Storage

Page 13

Return

• Floppy disks are used to store and transport data from one computer to another. Floppy disks are named as such due to the fact that data is stored on a very thin flexible, or floppy, plastic disk

• Hard disks are typically used to store programs and very large data files. Hard disk have a much larger capacity and are able to access information much faster than floppy disks

• Optical disks use laser technology and have the greatest capacity. Examples of optical disks include: compact discs (CDs), digital versatile discs (DVDs), high definition (hi def) discs

1-39

Communications

Page 13

• Communication Devices provide microcomputers with the ability to communicate with other computer systems across the globe

• The modem is the most widely used communication device

• Modems modify telephone communications into a form that can be processed by a computer

• Modems also modify computer output into a form that can be transmitted across standard telephone lines

1-40

Data

• Raw, unprocessed facts• Processed data becomes information• Stored electronically in files

– Document files– Worksheet files– Database files– Presentation files

Page 14

1-41

Document Files

• Created by word processors to save documents such as memos, term papers, and letters

• Create text-based documents• One of the most flexible and widely used software

tools• Features to make entering, editing, and formatting

documents easy

Return

Page 14

1-42

Worksheet Files

• Created by electronic spreadsheets to analyze things like budgets and to predict sales

• Files created by spreadsheet programs• Uses functions and formulas to analyze numeric

data• Manipulates numeric data• Features include workbooks, worksheets, cells,

ranges, text and numeric entries, formulas, functions, charts, recalculation, and what-if analysis

ReturnPage 14

1-43

Database Files

• Typically created by database management programs to contain highly structured and organized data

• A database management system (DBMS) or database manager is a program that sets up, or structures, a database

• Files created by database management programs• Organizes data for efficient retrieval• Is the electronic equivalent of a file cabinet• It also provides tools to enter, edit, and retrieve

data from the database

Page 14

1-44

Presentation Files

• Created by presentation graphics programs to save presentation materials. For example, a file might contain audience handouts, speaker notes, and electronic slides.

• Used to create a variety of visual objects to create attractive, visually interesting presentations• Features include slides, AutoContent wizard,

color schemes, slide layouts, special effects, master slides, and design templates

• Presentation files may contain audience handouts, speaker notes, and electronic slides
