Lesson Content/Board Summary

The Keyboard and Its Sections

Definition of Keyboard

A keyboard is an input device used to type letters, numbers, and symbols into the computer. It allows the user to communicate instructions to the computer.

Types of Keyboard

There are different types of computer keyboards based on design and features.
The following are the types of keyboards:

Standard Keyboard: This type of keyboard has about 101 keys. It includes all the basic keys such as letters, numbers, function keys, and control keys.
Enhanced Keyboard: This keyboard has more than 101 keys, often about 104 or more. It includes additional keys like multimedia and internet control keys for modern computers.

Sections of the Keyboard

A computer keyboard is divided into several sections, each serving a special purpose.
The following are the main sections of the keyboard:

Alphabetic (Typing) Section: This is the main area of the keyboard that contains letters A–Z, numbers 0–9, and punctuation marks. It is similar to a typewriter.
Function Keys Section: This section contains keys labeled F1 to F12 located at the top of the keyboard. These keys perform special functions depending on the software being used.
Numeric Keypad Section: Found on the right side of the keyboard, this section has numbers 0–9 and mathematical symbols. It is mainly used for calculations and entering numbers quickly.
Control Keys Section: This section contains keys such as Ctrl, Alt, Esc, Shift, and Windows key, which are used in combination with other keys to perform specific tasks.
Navigation (Cursor Control) Keys Section: This section includes the arrow keys and other keys like Home, End, Page Up, and Page Down used to move the cursor around the screen.
Special Keys Section: These include keys such as Enter, Backspace, Spacebar, Tab, and Caps Lock used for editing, spacing, and formatting during typing.

Teaching Methods/Instructional Techniques:

Lecture, Discussion, Explanation, Demonstration, Group Work, Question and Answer, Visual Aids
