Basic Computer Knowledge for Beginners

noreply@blogger.com (Mahadi M) — Sun, 23 Aug 2009 16:22:00 +0000

Jumping on a computer for the first time can be fun and easy as long as you keep in mind that computers were designed to make life easier, not more complex. Unlike technology of the past, which was based on the all-in-one concept, PC systems usually come in parts, divided into hardware and software, although Mac systems are all-in-one. Hardware makes up the physical elements of the computer, such as the hard drive, whereas software provides the operating system and the programs that allow you to create computer files.

Multiple Brands

Since the 1990s, the most popular operating system has been Microsoft Windows, which appeals to the business community, while Apple MacIntosh (aka "Mac") has been a favorite among graphic artists, musicians and other high-end media users. Windows and its offspring (XP, Vista) run on a PC, which has come to mean any personal computer besides a Mac. Both Macs and PCs are powered by a chip known as the central processing unit or CPU. Intel and AMD are leading manufacturers of computer chips. Other popular PC brands include Hewlett Packard and Dell.

Files and Folders

The most basic product that can be created on a computer is a file. A file can be a letter, a report, a photo, a song, a video and anything else that can be produced digitally. A file is expressed by its file name followed by a dot and an extension. The extension makes it easy to recognize what type of file it is. For example, many documents are saved with the ".doc" extension, so "calendar.doc" would be an example of a file named "calendar" saved as a Word document. There are many different file extensions. You can organize files by putting them in folders, just like how a filing cabinet is a storage unit for folders filled with files. You can also store folders within folders.

Creating Files

Creating a computer file is a very simple procedure. It involves a few clicks. At the top of every program is usually an option called "File." Click "File" and then you'll see a drop-down menu that includes choices such as "New," "Open" and "Save." By clicking "New" you can start a new file. When you click "Open" you'll be able to open an existing file. "Save" is what you click as soon as you decide you want to archive the file for later use. Once you know how to create and store files you will want to learn more about specific software programs that will speed up your work. Microsoft Office is a suite of programs commonly used for general office functions.

Internet

noreply@blogger.com (Mahadi M) — Sat, 22 Aug 2009 15:15:00 +0000

The Internet or the Net is a collection of computers, all link together, to share information globally. It was first developed in the U.S. by two universities who were both working on the same contract and wanted to share their data. They were faxing information back and forth and then retyping it until they came up with a piece of software called Unix to Unix Copy Program or UUCP.

The Internet was born and has mushroomed outward from that point.

There are 4 things that are necessary to "get on the net" with a full graphic interface (picture, sounds, animation, etc...).

A computer - preferably with a fast processor (around 100 MHz or more) and lots of memory (16 meg or more)
A modem - preferably 56,000 baud or high speed digital
Browser Software - often installed with your operating system or can be downloaded off the Internet
An ISP - An Internet Service Provider is a service that connects your home or office computer to the Internet

Once you have purchased an account with an ISP you will be given an account name. This is often your email address as well. You will also be given a password and should also be provided with instructions on how to change the password to a unique and personalized. The generic password provided with your account should be change to one of your own. Protect your password as you would any personal identification number (PIN) number.

top

The ISP will also provide information on how to configure your software. This can be simple or difficult depending on your Operating System. Once configured you simply run the software to connect your computer's modem to the ISP's modem, giving you access to the Internet.

There are a number of pieces of software that work together to connect you to the Internet.

top

The first and most complicated is the dialer or socket software. This is the software that makes the physical connection with the ISP's computer and the internet. This needs to be configured only once but you will need instructions from your ISP on how to do this as each ISP has a different setup.

top

The second piece is an Internet browser. This is the program that locates websites for you and allows users to maneuver around (surf) the World Wide Web and view web pages. Some of the more popular browsers are Mozilla Firefox and Microsoft's Internet Explorer. Mosaic was the first browser and most modern browsers still use the basic model that the first browser used. Some other browser are Opera, Safari, Netscape as well as dozens of others. Before graphic browsers Lynx was the most popular browser and is still available for text browsing. New browser are being developed and current browsers are constantly updating there programs. It is extremely important to update your browser every once in a while. Some ISP have a proprietary type of browser though most have given up this practice as it limits the users abilities to browse the Internet.

Type the url or web address of the website that you want to visit in the address bar of your browser and press Enter or click Go. Collect your favorite websites by adding them to your Favorites or Bookmarks. To go to a Favorite or Bookmark, click on the menu and click on the link.

Another piece of software is an email program . This program controls sending, composing and receiving email. Most email programs can also be used to read postings on newsgroups.

Instructions for getting this software can be obtained from your ISP though you may have to download the newest version yourself.

top

There are many different ISPs. If you attend a university or college or belong to a military or government organization you can most likely get Internet access through your school or work. If not you will most likely buy access from a commercial provider.

Another option, if you are in a major center, is the Freenet. Many major cities have groups devoted to making the Internet accessible to the greater majority of people and create Freenets which allowing members free access to the Internet. They run on private and public donations. It is an excellent way of learning about the Internet in a helpful environment.

Once you are connected you will have access to Email, Newsgroups, the World Wide Web (WWW), File Transfer Protocol (ftp), Internet Relay Chat (irc), Search Engines, ICQ and other Internet Services.

Section Five: Software Applications

noreply@blogger.com (Mahadi M) — Thu, 20 Aug 2009 09:11:00 +0000

The last level of software is referred to as Applications. These are programs written to perform
specific functions - personal, professional, educational or recreational on the PC.
The applications you purchase determine the personality that a computer assumes when the
application is run. It can become a word processor, a game machine, a tutor, an accountant of a
graphic illustrator, etc.
Not all software is created equal. An inexpensive or free program can sometimes do as much as
a package costing several hundred dollars. Each package works a little differently - some are easier
to use than others.
The most popular software applications presently on the market include:
Word Processors These programs allow you to create, edit, save and print letters,
memos and other files containing text. Most word processors allow
you to change fonts, sizes and attributes (bold, underline) for text.
These applications have taken the place of the standard typewriter and
have made it possible to create professional office documents.
Spreadsheets These programs offer a number crunching tool. Accounting
departments, in general, have turned in their mechanical calculators in
place of spreadsheet programs.
Company budgets, financial projections and graphical representations
of current and past sales can be created with the use of a spreadsheet
application.
Databases These programs allow you to organize data in such a way that reports
may be generated to show patterns that may have otherwise gone
unnoticed.
Databases have taken the place of paper folders and filing cabinets and
made it possible to quickly access reports based on specific conditions.
Graphics When presenting data to an audience, visual aides are always useful. It
is easier to understand a picture than it is an obscure number.
With the use of a graphics package you are able to create your own
images and visual aides.
Basic Computer Training Page 15 of 15
Communications Since the majority of work is now performed on a computer it is
essential that two or more computers in different regions, or even
countries, are able to converse just as two humans talk on the phone.
Communication packages allow data to be transferred between two
computers in the same amount of time as it would take for a phone call
to be placed.
It could be by email, computer fax software, instant messaging, etc.
Desktop Publishing Desktop publishing programs help you to create newsletters, reports,
manuals, flyers and other documents in which appearance is as
important as the content.
The text itself is usually entered in another program and then brought
into the desktop publishing package to be formatted.
The software allows you to control the layout of your document by
formatting the pages, drawing ruler lines, creating columns of text, sizing
and placing graphics and inserting headlines. These packages allow you
to produce professional looking documents.
With the powerful word processing packages available today many of
the desktop publishing features can be accomplished using the tools
within the word processor itself.

Section Four: Welcome to Windows

noreply@blogger.com (Mahadi M) — Tue, 18 Aug 2009 16:09:00 +0000

Windows is a big program that is called an “operating system”. It is the master program that runs
all of the other programs you use on your computer. It is also the program you use to give your
computer instructions to make it do things.
In order to get the most out of your computer, it’s important that you understand the key parts of the
Windows operating system. Windows was designed to be both easy and highly visual.
By the way. For now you can consider Windows 95, 98, 2000, ME, etc to be the same. Whenever
any significant differences between them need to be explained it will be done at the time.
Windows Terminology
Imagine that you are sitting at an electronic desk. When your computer starts up and no programs
are running you will see what is called the “desktop”. On the desktop you will see little pictures.
These pictures are called “icons”.
On every Windows desktop is an icon called “My Computer”. It resembles
a computer. Another icon is labelled “Recycle Bin”. This one looks like a
trash can and may be empty or full which we will discuss later.
Another object on your computer screen looks like a little arrow. It is called the “pointer”. Think of
it as an electronic finger you use for pointing to things on the screen. The pointer is attached to the
mouse so when you move the mouse the pointer moves too. The pointer is important because it
tells you where on the computer screen your electronic finger is pointing.
You can use the mouse to point to things like programs or folders. You do this by moving the pointer
on top of the icon. By then clicking the left button on the mouse, you can tell the computer to run the
program or open the folder.
Also on the desktop is what is called a “task bar”. It is a light gray (usually) bar usually located at
the bottom of the screen. An indicator that you are looking at the task bar is when you see the
“Start” button at one end and the clock at the other end as shown below.
Basic Computer Training Page 10 of 15
If you don’t see the task bar it might be hidden from view or moved around the screen. You can find
it by using the mouse to move the pointer all the way to the edge of the screen. You may have to try
all four sides to find it but when the pointer bumps into it, the task bar jumps out and becomes
visible. After you move the mouse pointer off it will automatically disappear again.
On the task bar if you move the pointer
over the clock a pop up box will appear
telling you the current date. If you click
once on the start button a list of available
options will pop up and if you right click on
the Start button an alternative menu
appears allowing you to use the explorer,
etc. which will be explained later.
In Windows just about every program you run will appear on your screen as a small rectangular box
called a window. Either a name or information inside the window tells you what program you are
running. The program will also appear on the task bar.
Become familiar with the following parts of a window as shown above. Don’t worry if you don’t
understand them yet as they will be explained later on in the manual.
Application
This is simply another name for a program.
Open
This means to begin running a program.
Close
This means to quit or exit a program. When you close a window, it disappears from the desktop.
You can close any window by clicking on the “X” in the upper right hand corner of the window you
want to close. This will also close any program that is running inside the window.
Drag
Place the pointer over an icon by moving the mouse. Press the left button and hold it down. While
holding the left button down, move the mouse and watch the icon move with it. You can literally drag
the icon around the screen. When you move the icon to where you want it release the mouse
button.
Double-Click
Quickly press down twice on the left mouse button. You should hear the button click each time you
press it. If you don’t click twice quickly enough the computer won’t know what you want to do.
Basic Computer Training Page 11 of 15
Execute
This simply means to run a program or launch an application.
File
A file an be either a program or part of a program. A file contains information you have generated.
If you have created a letter in Word Perfect and have saved it the saved letter is called a file.
Folder
Files are kept inside folders. In fact, your computer stores information much as you would store it
in a file cabinet.
Gadget
A gadget is a small icon that is used to make something happen on your screen. Good examples
are the “Close” gadget in the upper right hand corner of a window (it is an “X”), or the “Scroll
bar” in a window.
Pointer
the pointer, you might recall, is your electronic finger that is controlled by the mouse. The pointer is
usually shaped like an arrow but it can change into other shapes as you run programs. For example,
if your computer is busy working on a task the pointer change into an hourglass, letting you know
that you should wait until the computer is done.
Input
This is a verb meaning to place information into your computer. For example, if your computer asks
you a question such as “What is your name” and you respond by typing your name, you are
inputting.
Install
When you put a new program on your computer you are installing it. This enables you to run it.
Launch
This means to run or execute a program or to start using an application.
Left Click
Pressing the left mouse button with your fingers and releasing it. The more you use your mouse the
more you will get the hang of it.
Basic Computer Training Page 12 of 15
Maximize
The maximize gadget is located on every window in the upper right hand corner. It is the middle
button that looks like a square. When you click the maximize gadget it will enlarge the window so
that it fills up your entire desktop. Once you have your screen maximized the button will change to
have 2 overlapping squares. The gadget has now changed into the restore button. If you click the
button once it will enlarge your screen but, if you click it again it will make your screen appear half
the size which is handy for working on multiple projects.
Minimize
This is the small gadget located in the upper right corner of every window to the left of the maximize
gadget. If you press the minimize gadget it appears to make the window disappear. If you look at
your taskbar, you will see a small rectangle with the name of the window or program you just
minimized. If you left click once on the rectangle the window will return to the size it was before you
minimized it. This feature comes in handy when you are working on multiple programs and are
moving back and forth between them.
Menu
A menu is a list of commands and options you can give the computer.
Right Click
This means pressing the right button on your mouse with your finger and releasing it. You only need
to click the right button once.
Run
This simply means to start something on the computer. When you double click on a program to
start it, you are running a program.
Save
This means to put your work onto a floppy, CD or your hard drive so you can retrieve it and use it
later.
Scroll Bar
On the right side and along the bottom of some windows is a slider with arrows at each end.
These are “scroll Bars”.
Place your pointer on either the vertical or horizontal bar and drag it up and down or side to side.
If there is a very big picture on your screen that won’t all fit in a window, scroll bars will appear.
You can then click on the arrows to view the other parts of the image.
Basic Computer Training Page 13 of 15
Shortcut
A logical name for a bookmark to a program or a file that you use frequently. For example, if you are
working on a letter, you could create a shortcut to that file on your desktop. The next time you
wanted t work on the letter, you could double click on the shortcut to start the associated program
and load the file in one step.
Start Button
This is labelled “Start” on the task bar in the lower left corner. Use this button to start programs and
to perform many important tasks on the computer and to shut the computer off.
Task Bar
This is the bar containing the start button and the clock. It shows you what tasks or programs you
are running by placing them in small rectangle boxes. You can quickly switch from program to
program or window to window by clicking the appropriate box in the task bar. If nothing is showing
in the task bar, you an assume that no programs are running, or that no files or folders are open.
Title Bar
This appears at the top of each window and contains the name of that particular window. Usually
the computer puts inside the title bar the name of the program or file that is being displayed in the
window. Moving a window is easy. Just point the pointer over the title bar, click on the left mouse
button and hold it down, and then drag the window anywhere on your desktop.
Window
A box that appears as you run or open things on your computer is called a window. Everything you
do happens in a window and you can have multiple windows open at once.

Section Four: Welcome to Windows

noreply@blogger.com (Mahadi M) — Tue, 18 Aug 2009 16:09:00 +0000

Section three: Getting Started

noreply@blogger.com (Mahadi M) — Mon, 17 Aug 2009 15:17:00 +0000

The real trick to learning about computers is just to play with them. It is vital to get in as
much hands-on experience with a computer as you can.
Don’t worry about hurting the computer. It can tolerate most of your mistakes. If you don’t
understand something just go back, try it again and then again if necessary.
Turning on the Computer
Before you turn on your computer make sure that you do not have any floppy disks in the drives. If
you do then eject them by pressing the small button next to the disk slot. If a floppy is left in its slot
can oftentimes keep a computer from starting properly.
Make sure everything is plugged in and ready to go. First, turn the monitor on by pressing its power
button, then, if your speakers have their own power switch, turn that on. Finally, turn on the
computer. Turning on your computer is called “booting” the computer.
First you will see a black screen with some text on it. Your computer runs a self test and you may
see numbers counting up very quickly. After that Windows will begin to load. You will know when
Windows has finished loading with your monitor’s desktop displays the “My Computer” and “Recycle
Bin” icons.
If you happen to get a window that asks you how to boot and displays a list of options, choose
“Normal Boot”. This sometimes happens if the computer was turned off improperly. It is nothing
to worry about unless you continuous shut down improperly. If you can’t get the computer to get
pass this point or if the Windows screen doesn’t appear you may have a problem or your computer
may have been altered in some way. It would be the time you should call in tech support.

Section Two: The Mouse The

noreply@blogger.com (Mahadi M) — Sun, 16 Aug 2009 16:14:00 +0000

The mouse pointer can be seen in the form of an arrow on the screen. The arrow appears roughly
in the middle of your display. If you were to turn the mouse over, you would see a small, hard rubber
ball visible through a circular hole.
As you move the mouse on your desk the ball rotates. Deep within the mouse’s case are sensors
that keep track of the movement of the rollers. As the ball rotates, the sensors read the direction of
movement and send the information back to your computer’s serial port for interpretation by the
mouse driver program and this information is then relayed to the program you are running.
The mouse pointer can be used for selecting commands, accessing the menu, scrolling, moving
the cursor position and selecting data. Simply move the mouse pointer around on the screen until
it touches the desired icon, menu option or block of text.
The mouse can either have two or three buttons. The button perform different actions depending
on which program you are using. In Windows, however, the [LEFT] and [RIGHT] buttons are
usually the only ones used. Below is a brief explanation detailing the use of these two buttons:
Button Action
[LEFT] Used to select menu options or commands by pointing to the command or
option and clicking (pressing) this button once.
To get out of a menu, click this button anywhere away from the menu.
[RIGHT] Used to access shortcut menus within Windows and Windows applications.
The four basic mouse operations are moving, clicking, double-clicking, and dragging:
Moving Sliding the mouse around to change the location of the pointer.
Clicking Moving the mouse pointer onto an object and clicking the left button.
Double-Clicking Clicking the [left] mouse button twice (fast). This is usually done in lieu of
pressing the “Enter” key.
Dragging Moving the mouse pointer onto an object, pressing the left button and then
moving the mouse while continuing to hold the left mouse button down.

Section One: Learning Computer Basics

noreply@blogger.com (Mahadi M) — Sat, 15 Aug 2009 14:32:00 +0000

By getting acquainted with the basic parts of a computer you can become familiar with some of the
common terms people use when they talk about computers. Here are the simple parts of a
computer. These parts are commonly known as hardware.
Cards
These are the little boards made of plastic that connect or plug into the Motherboard. They are small,
specialized little computers that each do a different job. Sometimes you may have to connect cables
and other things into the card. Connecting cables into a card is often called plugging the card. Just
like you plug a lamp into an electrical outlet you plug your speakers into the sound card.
CD-Rom
This looks like an ordinary CD-Rom you would use to play music except these store
programs.
CD-Rom Drive
This is where you put the CD-Rom you want to use. It opens when you press the button on the front.
When the tray comes out, place the CD on it, label up, then push the tray back into the computer.
On most CD-Rom Drives pressing the button will also close the tray automatically.
Disk Drive
This is the small slot on the front of your computer with a button under it. You insert ‘Floppy disks”
into it. To retrieve the disk just press the button.
Floppy Disk
These are flat, square things with a metal centre that looks a lot like a plastic coaster in
shape anyway. They are used to save the things you do on the computer to file for later
use or maybe to use to transfer data from your computer to another, etc.
Hard Drive
This is like a larger floppy except that you can’t see it or take it out of the computer because it is
build inside of the computer case and stores all the information needed to operate your computer.
Basic Computer Training Page 2 of 15
Keyboard
The keyboard is designed much like the typewriter and it also works just like
one. Type the letters and/or numbers and they appear on the screen.
Microphone
Your computer may or may not have a microphone connected to it but if you do, it plugs into the
“Sound Card” receptacle on the back of your computer. You can use it to record sounds.
Modem
The modem makes the connection with the Internet. Plug it into your telephone jack on the wall
where your phone normally is plugged in. The phone then plugs into the back of the modem. The
other end of the modem is built right into your computer. Some modems can also be used a fax
machines and others can even be used as a voice mail system.
Monitor
This is what looks like a television set and works almost exactly the same way. The
main difference is that its special cord plugs into the back of your computer.
Motherboard
Everything inside of your computer - the CPU (Case), the Sound Card, etc. plugs into this big, flat
board that is also inside. The Motherboard is thought of as the backbone of the computer.
Mouse
This is the small hand-held device you roll around on a mouse pad. It has two or
sometimes three buttons on it, most have a small ball in the bottom of it and a long wire
coming out of it that plugs into the back of the computer. There are also wireless ones
available. You will use the mouse to move things around the computer screen and to give
commands to the computer.
Printer
This is the device that you put paper into and it prints the work you have
done on the computer onto the paper. Some printers have the capability to
print in color as well as black and white. If you are not sure whether you can
or not, take a quick look to see if your printer has the word “color” written
somewhere on the front of its case.
Programs
A program is the term used for anything special your computer does for you. There are programs
that enable you to do just about anything - from playing games to making posters. Programs are
also referred to as Software.
Basic Computer Training Page 3 of 15
Software
This is a fancy name for “Programs”. Some software comes pre-installed on your computer. You
can find software to do thousands of jobs.
Scanner
Some computers have a device connected to them called a scanner. I look at it as a
camera for the computer. You place things on the glass surface of the scanner, close
the lid and the scanner takes a picture that shows up on your computer.
Sound Card
This is one of the little boards that plugs into the motherboard. It is the part that makes all the sounds
you hear when you are using the computer. This is the card that enables you to play a music CD
on your computer. The speakers and the microphone all plug into the sound card.
Speakers
These are much like the ones you have on your stereo but probably a little more compact.
They make the sounds and play the music you hear from your computer. Some speakers
are built right into your monitor and others are separate.
Video Card
Your monitor plugs into a video card. It is the part of the computer that puts up the images you see
on the screen and makes the pictures move.
Word Processor
This is a specialized program used to create letters and other typed documentation. The more
expensive word processors can help you with spelling and grammar.
Viruses
A virus is a special type of program that is meant to cause your computer to do something bad.
Some viruses can wipe out all the information on your computer and others are like an April Fools’
joke and make strange or annoying messages appear on your screen. You can get viruses by
sharing disks, CDs or programs with others or you can get them by downloading files or programs
off of the Internet. There are special programs you can install that will help you find and remove any
viruses you may have on your computer.
OVERVIEW
Take some time reviewing the terms we just went over and soon you will feel comfortable with the
parts of your computer and their locations. Now when one of these terms is referred to later on you
will know what it is and what it is used for. That is all there really is to your computer. You don’t need
to know anything more technical than this to use and enjoy a computer.

Health and Safety

noreply@blogger.com (Mahadi M) — Thu, 13 Aug 2009 16:03:00 +0000

Health and Safety is crucial to the effective operation of a computer. Stress is widely accepted as a common and possibly the most dangerous aspect of using a computer.

It is possible to use a computer safely if a few simple rules are maintained.

Musculoskelatal problems can occur when improper office equipment is used. Chairs should be adjustable so that legs are at a right angle. The back should have good support for the spine and lower back. The seat should swivel and be made from fabric that is porous.

Eye strain can be caused by staring at a fix object for extended periods of time (like a computer). People who use glasses may have to get their prescriptions changed and people who use bifocals can find that the line interferes with the screen and trifocals triple the problem. Regular users of computers may develop focusing problems. Temporary colour distortion has also been reported.

A safe working environment is crucial. Ventilation is an integral part of the new technological workplace. Though standards are set by the manufacturer of computer equipment the modern office has many different pieces of equipment. All electronic equipment emit some level of electromagnetic field which, on it's own, most likely isn't a concern but when combined with other equipment can create hazardous working environments. Pregnant women should take extra care when working around electromagnetic fields. Like any piece of equipment, computers should have scheduled maintenance.

Stress is caused by many things including poor or inadequate training, monitoring, fear of new technology, lack of control over work, physical problems, hardware problems causing delays, poor layout of work space and the myriad of other problems that people experience that combine to create stressful situations.

Time away from the computer during the work day is crucial! This gives the body a chance to stretch and gives the eyes a chance to rest. Breaks should be scheduled and followed with great discipline. Computers, even more so than television, have a mesmerizing effect on the user so that it is easy to work right through breaks without noticing.

There are many other issues to be discussed around computer health and safety but it is important to understand that there are problems and solutions to those problems that the user, administrator and manager must address.

Basic Computer Operations

noreply@blogger.com (Mahadi M) — Thu, 06 Aug 2009 17:06:00 +0000

How Computers Work

Input: Information and programs are entered into the computer through Input devices such as the keyboard, disks, or through other computers via network connections or modems connected to the Internet. The input device also retrieves information off disks.

Output: Output Devices displays information on the screen (monitor) or the printer and sends information to other computers. They also display messages about what errors may have occurred and brings up message or dialog box asking for more information to be input. The output device also saves information on the disk for future use.

Processing: The CPU or central processing unit is sometimes called the Control Unit and directs the operation of the input and output devices. The Coprocessor or the Arithmetic-Logic Unit does arithmetic and comparisons. The memory or RAM temporarily stores information (files and programs) while you are using or working on them. The BIOS or basic input/output system controls the dialogue between the various devices.

Keyboard Layout and Data Entry

ENTER or RETURN - Moves the cursor down one line and to the left margin. Enter also process commands such as choosing an option in a dialog (message) boxes and submitting a form.

DEL or DELETE - Deletes the character at cursor and/or characters to the right of the cursor and all highlighted (or selected) text.

BKSP or BACKSPACE - Deletes the character to the left of cursor and all hightlighted text.

SPACE BAR - Moves the cursor one space at a time to the right

SHIFT KEY - Use the shift keys to type capital letters and to type the upper character on keys with two characters on them

CAPS LOCK - Locks the keyboard so it types capital letters (a light goes on when caps lock is on)

TAB - Moves the cursor five spaces to the right (number of spaces are usually adjustable). Tab moves to the next field in a form or table (Shift-Tab for previous field).

ESC or ESCAPE - Cancels a menu or dialog box

ARROW KEYS - Moves the cursor around document without changing text

FUNCTION KEYS or F KEYS - Access commands by themselves or in combination with the three command keys; CTRL, SHIFT, and ALT

Command or Special Keys

Command keys normally do nothing on their own but work in combination with other keys. Each piece of software uses the command keys differently though there is a move to standardize some functions. The Control key or Ctrl is often used to access commands. The Alternative key or Alt is often used to access menus. The Shift key is used to type CAPITAL LETTERS. As well the command keys are all used to move through documents and edit text faster and easier. As well many computers have Special keys design specifically for the particular computer. Apple computers have the Apple keys and Macs have Command keys. Many keyboards now have a Windows key specifically for Windows 9x and newer systems. Many older computers also have special keys used for a variety of different functions.

Some Notebook or Laptop keys are left out because of space limitations and they usually have a Special function key which allows other keys to double for the missing ones.

Basic Typing Rules

Place one space between each word, after a punctuation mark and at the end of a sentence. Always start a sentence with a capital letter. Use capitals for names, addresses, provinces and countries, places, organizations, businesses, associations, schools, colleges, universities, days of the week, months, holidays, nationalities, ethnic groups and languages.

Learning the keyboard is the first step to learning computers. Learning involves practice. It really is as simple as that. There are two kinds of typing.

The first is called Touch Typing. The Touch Typist uses the Home Keys (asdf for the left hand and jkl; for the right) and all the fingers on both hands as well as the thumbs for the Space Bar while typing. There are many commercial and public domain programs that are designed to teach this method.

The other method is some times called 'Hunt and Peck' or depending on finger strength 'Search and Destroy'. This involves using one or more fingers on one or two hands to type. It is a perfectly acceptable way of using a computer and many people get along fine with this technique.
