TOPIC: DESKTOP ICONS

Objectives:
1) Identify common desktop icons.
2) Recognize the advantages of desktops icons.
3) Create desktop shortcuts.
LEARNING CONTENT
A computer desktop has a collection of icons, some of which appear when
you install programs or when you install a new operating system. Icons that has an
arrow are known as shortcut or links to a programs, files or folders stored in your

5
computer. Double clicking a desktop icon enables to launch that specific program,
file or folder. Here are some of the common desktop icons:

PROGRAM ICONS
These icons contains an arrow and represent shortcuts to various
programs. Deleting a shortcut does not mean deleting the actual program,
only the desktop icon link to it.
1) Microsoft Word 365 (word processing program)

2) Google Chrome (internet browser)

3) Acrobat Reader DC (to view PDF files)

FOLDERS AND DRIVES ICONS

Icons that display a folder represent a shortcut to a folder while an icon
that show a hard disk represent a drive installed in your computer. Double
clicking a folder icon or drive icon enables to view and see all the contents of
that folder or drive.

FILES ICONS
Icons that display a page are files. Double clicking that icon enables
you to open the file in the program that it was created in. If no arrow appears it
is not a shortcut and indicates that it is actually saved to the desktop.
Therefore, if it was deleted, so is the actual file.

6
 RECYCLE BIN ICON
The desktop icon for recycle bin is display as a waste paper basket
with the recycle symbol on it. Double clicking this icon will open the recycle bin
window, allowing you to permanently delete or restore files as necessary.

option from the dialog box. This will redirect you to another dialog box. From
there, choose the Shortcut option.

2) Look for a new window asking you to browse the location of the file for which
you want to create the shortcut. You must choose the browse option and
browse the file location. As soon as you choose the location, the box will be
filled itself by the location.

3) Click Next option present somewhere at the right-bottom of the working

window.

7
 4) Type a name for the shortcut. If a Finish button appears at the bottom of the

click it, choose the icon you want to use for your shortcut, and then click
Finish.

TOPIC: KEYBOARD TECHNIQUES
Objectives:
1) Be familiar with different keyboard shortcuts.
2) Appreciate the importance of keyboard techniques.
3) Practice proper typing technique.

LEARNING CONTENT
Keyboarding refers to the ability to enter text by using the appropriate fingers
without looking at the keys. Enabling to use to the computer more effective and more
productive. To better understand keyboard techniques, it is important to know the
keyboard layout below:

• The central portion of the keyboard includes alphanumeric keys.

• A smaller section to the right contains the numeric keypad.
• A small set of function and directional keys between the letters and the
numeric keypad.
• A row of function keys across the top used for computer commands.

KEYBOARD TECHNIQUE
1. Home row position – it is the home position for your fingers. It should be
curved and placed on home room keys. Use bumps on F and J keys to keep
fingers in place.
a. Left hand – letters A, S, D, F
b. Right hand – letters J, K, L
2. Eyes on copy – eyes should stay on text that is being keyed at all times and
not at your keyboard for the reason that you will lose your place.
3. Feet flat on the floor – your feet serve as an anchor to your body when
keying. This will help your body from moving around with proper alignment
and posture.
4. Keyboard placement – this should be placed at the end of the desk and your
body must be a hand span away from the desk.

TOPIC: KEYBOARD CARE AND MAINTENANCE
Objectives:
1) Understand the keyboard care and maintenance.
2) Enumerate ways in cleaning your keyboard.
3) Put emphasis on the importance of keyboard care and maintenance.

LEARNING CONTENT
Dust is not just unpleasant—it can possibly harm or even ruin parts of your
computer. Cleaning your computer consistently will help you keep it working well and
prevent expensive repairs.
Dust, food, liquid, and other particles can get trapped underneath the keys on
your keyboard, which can avoid it from working properly. The simple cleaning tips
below can help keep your keyboard clean.

• Unplug the keyboard from the USB or PS/2 port. If the keyboard is plugged
into the PS/2 port, you will need to shut down the computer before unplugging
it.
• Turn the keyboard upside down and gently shake it to remove dirt and dust.
• Use a can of compressed air to clean between the keys.
• Moisten a cotton cloth or paper towel with rubbing alcohol and use it to clean
the tops of the keys. Do not pour alcohol or any other liquid directly onto the
keys.
• Reconnect the keyboard to the computer once it is dry. If you are connecting it
to a PS/2 port, you will need to connect it before turning on the computer.

Dealing with liquids

If you spill liquid on the keyboard, quickly shut down the computer and disconnect
the keyboard. Then turn the keyboard upside down and allow the liquid to drain.
If the liquid is sticky, you will need to hold the keyboard on its side under running
water to rinse away the sticky liquid. Then turn the keyboard upside down to drain for
two days before reconnecting it. Please note that keyboard may not be fixable at this
point, but the method above is probably the best option. To prevent this situation
altogether, we recommend keeping drinks away from the computer area.
