Lesson Overview:

Types of Computers

A computer is an electronic device that processes data. The earliest computers took up entire

rooms. Today, a powerful computer fits in your backpack or even your pocket. Computers can

be grouped in several different ways: by size, by purpose, or intended use, or by how many

people use them.

A personal computer (PC) is used by one person at a time. Desktop and laptop

computers, MP3 players, and personal digital assistants (PDAs) are all examples of PCs,

which are also called microcomputers.

A minicomputer can be used by several people to hundreds of people at one time. These

computers are often used in small-to-medium sized organizations, such as schools.

A mainframe, or supercomputer, is so large that it can fill several rooms. These

computers are used by thousands of people at the same time in organizations such as

corporations and government agencies.

Essential Question 1: Compare and Contrast- What are the differences between

mainframe computers and minicomputers?

Day 32 (Lesson 32 – Computer Operations)

How Does My Computer Work?

When you shoot a basketball, your eyes, brain, and muscles send many signals back and forth.

When you use a computer, you send signals to the computer’s central processing unit (CPU),

which is like the computer’s brain. A CPU, or microprocessor, is a small chip that performs

calculations and carries out all the instructions you give to your computer. Every time you press

a key on the keyboard or move the mouse, you give instructions to the CPU. A faster CPU

generally means that a computer can process more data in less time. The process of receiving and

carrying out one instruction is called a cycle. The speed of a CPU is measured in:

Megahertz (MHz) – millions of CPU cycles per second

Gigahertz (GHz) – billions of CPU cycles per second

Bits, Bytes and Binary Numbers

Computers can process only two numbers: 1 and 0. All data are computer process is turned into a

string of 1s and 0s called binary numbers. A bit is the smallest unit of information, always either

a 1 or a 0. Each letter, number, and symbol that we use in English is presented by eight bits.

Eight bits make a byte, the building block for all information that flows through a computer. A

computer file can contain thousands, millions, or even billions of bytes. A five-page research

paper may use 40,000 bytes, (or 40 KB). A movie on a DVD holds around five billion bytes (or

5GB).

The word “cool” uses four bytes – one for each letter. How many bits does it use?

Essential Question 2: Identify - What are the only two numbers that a computer can

process and what are they called?

The word “cool” in binary numbers

Day 33 (Lesson 33 – Hardware Basics)

Hardware Basics

Hardware is the collection of physical devices that make up your computer system. These

devices are also called components.

How Do I Connect Components?

Many of our hardware devices need to be connected to your computer. Devices such as your

monitor and keyboard may have cables with connectors at the end. These connectors are then

plugged into a port in the computer. Each port requires its own kind of connector. This makes it

easy to know which cable to plug into the correct port.

Essential Question 3: Identify – What are three hardware components that you can see

outside the computer and three components that are hidden inside the computer?

Day 34 (Lesson 34 – Input and Output Devices)

What are Input and Output Devices?

When you use a computer, information travels from you to the computer and back to you. Input

devices and output devices are components that you use to communicate with your computer.

Input is when a use enters information into a computer. Output is when a computer delivers

information back to a user.

Essential Question 4: Explain – What is the difference between input and output?

Example Description

Inp

ut

Dev

ices

A keyboard is used to input text and numbers and to

send commands to a computer.

A mouse is used to click icons and buttons, highlight

text, and drag images, text, files, and folders.

A scanner, like a photocopier, lets you create an

electronic snapshot of an image or a page of text.

Many digital cameras connect with computers so

that you can download, edit, and e-mail the photos

you take.

A joystick, used for computer games, controls

movement on the screen.

A monitor displays the text and graphics that you

input or download into the computer.

A printer takes electronic information from the

computer and produces a paper copy, which also is

called a hard copy.

Speakers are used to play music on your computer

and give you “alert” sounds as you work.

Day 35 (Lesson 35 – Computer Memory and Storage Basics)

What does a computer do with all the data it processes? A computer stores data in three main

places: in its random-access memory (RAM), in its read-only memory (ROM), or on a storage

device. A computer mainly uses two different kinds of memory, RAM or ROM, depending on

the kind of task, or assigned work, the computer is performing.

Types of Computer Memory

Memory Type What Is It? How Is It Like Human

Memory?

Read-Only Memory

(ROM)

This memory is permanent information

on your computer. ROM holds your

computer’s built-in instructions and

cannot be erased or changed.

Your brain automatically controls

many basis body functions, such

as breathing. Similarly, ROM

controls the basic functions of

your computer.

Random-Access Memory

(RAM)

This memory is temporary information

that your computer uses only when you

work with a particular file. It is erased

when you turn off your computer.

RAM is like you short-term

memory. Have you ever had to

remember something for just a

minute, such as a phone number?

You used your short-term

memory for that task.

Two kinds of computer memory are RAM and ROM. Which type of memory is similar

to short-term memory?

Southeast Middle School

Keyboarding – 6th Grade

Day 36 (Lesson 36 – Memory)

When Do I Use RAM and ROM?

RAM and ROM perform basic specific tasks that keep your computer running smoothly. For

example:

ROM works when you turn your computer on or off. ROM tells the computer how to start up

and instructs the operating system (OS) to start. When you turn on or shut down your computer,

the computer is using ROM.

RAM works when you start and use your software. After your computer starts, RAM takes

over. The computer is using RAM when your operating system starts, and you can see your

desktop. If you open a software application such as Microsoft Word and key your name, that

information is stored in RAM.

Essential Question 1: Explain – How is RAM like your short-term memory?

How Is Information Stored? If you shut down a computer without saving your work, you will lose your data. Before

you save your work, the data is stored in RAM. When you save a file, you move the

information from RAM to storage device, such as a hard drive, a server, or a disk. A

storage device is like your long term memory, where you keep memories of important

events and your family members’ names, for example.

Types of Storage Devices

Storage Device What It Does Size

Hard Drive

This is the major storage

device inside your

computer. It also is known

as the hard disk. External

hard drives are also

available.

40 GB to 320 GB or more

Flash Drives

These portable devices

plug directly into a

computer’s USB port.

Some are as small as a pen

or a keychain.

256 MB to 4 GB or more

CDs and DVDs These portable devices CD = 700 MB

DVD = 4.7 GB to 17 GB

Page 7: Southeast Middle School Keyboarding 6th Grade Introducing ......Keyboarding – 6th Grade Day 31 (Lesson 31 – Introducing Your Computer) Standards: Follow oral and written instructions

Floppy Disk

This portable device stores

smaller files such as text

documents.

Floppy disk = 1.44 MB

Zip disk = 100 MB to 750

MB

Essential Question 2: Explore – If you had a 1 GB file, where could you store it?

Closing:

Homework: On a sheet of paper, answer the following questions:

1. What type of memory gets erased when you turn off your computer?

2. Name three input devices and three output devices.

3. How is the human brain like a computer? Give examples.

Day 37 (Lesson 37 – Software Basics)

Software is a set of instructions that makes it possible for your computer to

perform tasks. It translates your commands into the language of binary numbers –

the 1s and 0s that computers understand. When you key a word, select a menu, or

click a button, software sends data to the computer’s CPU (Central Processing

Unit). Software also can be called a program or an application.

How Do I Use Software?

Operating system (OS) software is the main program that makes your computer

work.

Application software lets you do different tasks on your computer, such as writing

reports or sending e-mail.

Utility software helps you control, or exercise power over, your computer and

keep it in good running condition.

It is important to choose the right software program for the type of task you want

to do. The table below can help.

Types of Application Software

Type of Software What It Lets You Do Examples

Web Browsers Visit Web sites on the

internet

Microsoft Internet Explorer,

Apple Safari, Netscape,

Mozilla Firefox

E-mail Exchange messages and files

with other computer users

Microsoft Outlook, Eudora

Word Processing Create letters, term papers,

reports, newsletters, and so

on.

Microsoft Word, Corel

WordPerfect

Spreadsheet Work with numbers and

calculations to create tables,

charts, and graphs

Microsoft Excel, Lotus 1-2-3

Database Organize and retrieve large

amounts of information

Microsoft Access, FileMaker

Pro

Presentation Create a slide presentation to

show a group of people

Microsoft PowerPoint, Apple

Day 38 (Lesson 38 – Operating System)

What is an Operating System?

Every computerized device needs an operating system (OS) in order to work. The

operating system controls all the other software programs and allows your

hardware devices to work properly. There are many kinds of operating systems,

though most people use one of these types:

What is a GUI?

An interface is a point where two things come together. You need an

interface to communicate with your computer. To use older operating systems, you

had to key all of your commands using a text interface such as MS-DOS

(Microsoft-Disk Operating System). Today, your operating system uses a graphical

user interface, also called a GUI (pronounced “gooey”). A GUI lets you use a

pointing device, such as a mouse, to click images and icons or select commands.

The pointer usually displays as a small angled arrow. The Windows operating

system and the MAC OS use GUIs. Would you rather key all of your commands or

use a mouse to control your computer?

Microsoft Windows – the most popular OS for PCs.

Mac OS - is used by Apple computers. It works similarly to Windows, but it

has a slightly different appearance, or look.

Linux - is a powerful OS often used in large networks and business

environments.

Handheld operating systems – are used in PDAs, MP3 players, and cell

phones. These products use operating systems that were developed

specifically for them, called “proprietary software.”

Essential Question 1: Describe. Name six types of application software, and

describe what each one allows you to do.

Essential Question 2: Identify. What type of software program controls all the

other software on your computer?

Day 39 (Lesson 39 – Computer Network Basics)

Computer Network Basics

A computer network is a group of computers connected together. Networks

enable, or allow, people to share information and resources such as printers,

storage devices, and Internet connections. Most large networks, such as the ones in

schools and businesses, connect client computers to a central server. This makes a

school or company more efficient and also saves money in equipment costs.

Networks often are used in classrooms so that students have access to the same

information.

A network server is a powerful computer that lets users share storage space and

applications. A network server can be a PC or a large mainframe computer. A

client computer sends and receives information to and from a server. A client is

usually a PC, such as a desktop or laptop computer, or even can be a handheld

device such as PDA.

Essential Question 1: Identify. In a computer network, what do you call the

computer that provides stored space and applications to other computers?

Essential Question 2: Explain. Why is it helpful for schools or companies to use a

network?

Technology

and your

Health

I have believed for a while that mobiles, mobile phone masts and another technology is harmful to

our health, due to the exposure of radiation. Scientists at the very least think mobile phones should be

used as little as possible. They think it is better to be cautious about using mobiles and a lot of scientists

believe they are harmful to your health. Mobile phones are particularly bad for children. The phone

companies will tell you that they are safe. But remember they are selling a product so they are hardly

going to put you off buying their product by telling you it is unsafe. Where there is a lot of money

involved there tends to be corruption. So don't think that they or the government, who get a tax of the

money from the use of masts and mobile phones that are put up, have your best interests in mind.

After all people said that smoking, asbestos, a medication called Thalidomide, pesticides and so on

were either safe or wouldn't cause you serious harm. However they were wrong as they caused cancer,

disability and terrible illnesses.

I think technology will be to the next generation what drink, smoking and drugs have been to previous

generations. In fact research claims mobile phones could kill more people than smoking.

Wireless (wi-fi) can cause headaches, nausea, tiredness and memory loss in some people. Technology

can be particularly hazardous if you are sensitive to it. We have so much technology now there is 24

hour television, computers, Nintendo games, phones and so on. It is not just mobiles but Dect phones

(cordless) too and on top of all this there is wireless as well.

Electrical gadgets in the bedroom can also cause sleep problems. It is best to have no electronic items

in your bedroom. But if you can't do without them at least make sure you don't have a computer,

cordless phone or mobile in your bedroom or at least make sure that are turned off. Cordless phones

emit a high amount of radiation this is because they have to be on all the time so that the phone can be

charged up. If you didn't do this the phone wouldn't work. So keep your technology use to a limited

amount of time each day. Particularly keep your use of mobile phones to a minimum and use a landline

instead, because mobile phones can cause cancerous brain tumours if they are used for a long period of

time over the years.

Always remember that your health is very important as you might find you are unable to return to

good health once you have lost it.

Lesson Overview:

Types of Computers

A computer is an electronic device that processes data. The earliest computers took up entire

rooms. Today, a powerful computer fits in your backpack or even your pocket. Computers can

be grouped in several different ways: by size, by purpose, or intended use, or by how many

people use them.

A personal computer (PC) is used by one person at a time. Desktop and laptop

computers, MP3 players, and personal digital assistants (PDAs) are all examples of PCs,

which are also called microcomputers.

A minicomputer can be used by several people to hundreds of people at one time. These

computers are often used in small-to-medium sized organizations, such as schools.

A mainframe, or supercomputer, is so large that it can fill several rooms. These

computers are used by thousands of people at the same time in organizations such as

corporations and government agencies.

Essential Question 1: Compare and Contrast- What are the differences between

mainframe computers and minicomputers?

Day 32 (Lesson 32 – Computer Operations)

How Does My Computer Work?

When you shoot a basketball, your eyes, brain, and muscles send many signals back and forth.

When you use a computer, you send signals to the computer’s central processing unit (CPU),

which is like the computer’s brain. A CPU, or microprocessor, is a small chip that performs

calculations and carries out all the instructions you give to your computer. Every time you press

a key on the keyboard or move the mouse, you give instructions to the CPU. A faster CPU

generally means that a computer can process more data in less time. The process of receiving and

carrying out one instruction is called a cycle. The speed of a CPU is measured in:

Megahertz (MHz) – millions of CPU cycles per second

Gigahertz (GHz) – billions of CPU cycles per second

Bits, Bytes and Binary Numbers

Computers can process only two numbers: 1 and 0. All data are computer process is turned into a

string of 1s and 0s called binary numbers. A bit is the smallest unit of information, always either

a 1 or a 0. Each letter, number, and symbol that we use in English is presented by eight bits.

Eight bits make a byte, the building block for all information that flows through a computer. A

computer file can contain thousands, millions, or even billions of bytes. A five-page research

paper may use 40,000 bytes, (or 40 KB). A movie on a DVD holds around five billion bytes (or

5GB).

The word “cool” uses four bytes – one for each letter. How many bits does it use?

Essential Question 2: Identify - What are the only two numbers that a computer can

process and what are they called?

The word “cool” in binary numbers

01000011 01001111 01001111 01001100

Day 33 (Lesson 33 – Hardware Basics)

Hardware Basics

Hardware is the collection of physical devices that make up your computer system. These

devices are also called components.

How Do I Connect Components?

Many of our hardware devices need to be connected to your computer. Devices such as your

monitor and keyboard may have cables with connectors at the end. These connectors are then

plugged into a port in the computer. Each port requires its own kind of connector. This makes it

easy to know which cable to plug into the correct port.

Essential Question 3: Identify – What are three hardware components that you can see

outside the computer and three components that are hidden inside the computer?

Day 34 (Lesson 34 – Input and Output Devices)

What are Input and Output Devices?

When you use a computer, information travels from you to the computer and back to you. Input

devices and output devices are components that you use to communicate with your computer.

Input is when a use enters information into a computer. Output is when a computer delivers

information back to a user.

Essential Question 4: Explain – What is the difference between input and output?

A mouse is used to click icons and buttons, highlight

text, and drag images, text, files, and folders.

A scanner, like a photocopier, lets you create an

electronic snapshot of an image or a page of text.

Many digital cameras connect with computers so

that you can download, edit, and e-mail the photos

you take.

Day 35 (Lesson 35 – Computer Memory and Storage Basics)

What does a computer do with all the data it processes? A computer stores data in three main

places: in its random-access memory (RAM), in its read-only memory (ROM), or on a storage

device. A computer mainly uses two different kinds of memory, RAM or ROM, depending on

the kind of task, or assigned work, the computer is performing.

Types of Computer Memory

Memory Type What Is It? How Is It Like Human

Memory?

Read-Only Memory

(ROM)

This memory is permanent information

on your computer. ROM holds your

computer’s built-in instructions and

cannot be erased or changed.

Your brain automatically controls

many basis body functions, such

as breathing. Similarly, ROM

controls the basic functions of

your computer.

Random-Access Memory

(RAM)

This memory is temporary information

that your computer uses only when you

work with a particular file. It is erased

when you turn off your computer.

RAM is like you short-term

memory. Have you ever had to

remember something for just a

minute, such as a phone number?

You used your short-term

memory for that task.

Two kinds of computer memory are RAM and ROM. Which type of memory is similar

to short-term memory?

Southeast Middle School

Computer Applications - 8th Grade

Day 36 (Lesson 36 – Memory)

When Do I Use RAM and ROM?

RAM and ROM perform basic specific tasks that keep your computer running smoothly. For

example:

ROM works when you turn your computer on or off. ROM tells the computer how to start up

and instructs the operating system (OS) to start. When you turn on or shut down your computer,

the computer is using ROM.

RAM works when you start and use your software. After your computer starts, RAM takes

over. The computer is using RAM when your operating system starts, and you can see your

desktop. If you open a software application such as Microsoft Word and key your name, that

information is stored in RAM.

Essential Question 1: Explain – How is RAM like your short-term memory?

How Is Information Stored? If you shut down a computer without saving your work, you will lose your data. Before

you save your work, the data is stored in RAM. When you save a file, you move the

information from RAM to storage device, such as a hard drive, a server, or a disk. A

storage device is like your long term memory, where you keep memories of important

events and your family members’ names, for example.

Types of Storage Devices

Storage Device What It Does Size

Hard Drive

This is the major storage

device inside your

computer. It also is known

as the hard disk. External

hard drives are also

available.

40 GB to 320 GB or more

Flash Drives

These portable devices

plug directly into a

computer’s USB port.

Day 37 (Lesson 37 – Software Basics)

Software is a set of instructions that makes it possible for your computer to

perform tasks. It translates your commands into the language of binary numbers –

the 1s and 0s that computers understand. When you key a word, select a menu, or

click a button, software sends data to the computer’s CPU (Central Processing

Unit). Software also can be called a program or an application.

How Do I Use Software?

Operating system (OS) software is the main program that makes your computer

work.

Application software lets you do different tasks on your computer, such as writing

reports or sending e-mail.

Utility software helps you control, or exercise power over, your computer and

keep it in good running condition.

It is important to choose the right software program for the type of task you want

to do. The table below can help.

Day 38 (Lesson 38 – Operating System)

What is an Operating System?

Every computerized device needs an operating system (OS) in order to work. The

operating system controls all the other software programs and allows your

hardware devices to work properly. There are many kinds of operating systems,

though most people use one of these types:

What is a GUI?

An interface is a point where two things come together. You need an

interface to communicate with your computer. To use older operating systems, you

had to key all of your commands using a text interface such as MS-DOS

(Microsoft-Disk Operating System). Today, your operating system uses a graphical

user interface, also called a GUI (pronounced “gooey”). A GUI lets you use a

pointing device, such as a mouse, to click images and icons or select commands.

The pointer usually displays as a small angled arrow. The Windows operating

system and the MAC OS use GUIs. Would you rather key all of your commands or

use a mouse to control your computer?

Microsoft Windows – the most popular OS for PCs.

Mac OS - is used by Apple computers. It works similarly to Windows, but it

has a slightly different appearance, or look.

Linux - is a powerful OS often used in large networks and business

environments.

Handheld operating systems – are used in PDAs, MP3 players, and cell

phones. These products use operating systems that were developed

specifically for them, called “proprietary software.”

Essential Question 1: Describe. Name six types of application software, and

describe what each one allows you to do.

Essential Question 2: Identify. What type of software program controls all the

other software on your computer?

Day 39 (Lesson 39 – Computer Network Basics)

Computer Network Basics

A computer network is a group of computers connected together. Networks

enable, or allow, people to share information and resources such as printers,

storage devices, and Internet connections. Most large networks, such as the ones in

schools and businesses, connect client computers to a central server. This makes a

school or company more efficient and also saves money in equipment costs.

Networks often are used in classrooms so that students have access to the same

information.

A network server is a powerful computer that lets users share storage space and

applications. A network server can be a PC or a large mainframe computer. A

client computer sends and receives information to and from a server. A client is

usually a PC, such as a desktop or laptop computer, or even can be a handheld

device such as PDA.

Essential Question 1: Identify. In a computer network, what do you call the

computer that provides stored space and applications to other computers?

Essential Question 2: Explain. Why is it helpful for schools or companies to use a

network?
