1. WHAT IS KEYBOARD?
A computer keyboard is an input device used to enter
characters and functions into the computer system by
pressing buttons, or keys. It is the primary device used to
enter text. A keyboard typically contains keys for individual
letters, numbers and special characters, as well as keys for
specific functions. A keyboard is connected to a computer
system using a cable or a wireless connection.

2. COMPONENTS OF
KEYBOARD.
1. Keycaps
2. Switches
3. Circuit Board
4. Backplate
5. Cable and Connections

3. 1. Keycaps
Visible keycaps have
individually labeled detachable
coverings for keyboard keys,
each with a distinct character or
symbol. They offer a tactile
surface for users to push,
allowing them to enter data into
a computer or gadget.

4. 2. SWITCHES
These devices sit under
specific keys and capture
pressed keystrokes. Different
kinds of switches provide
additional tactile feedback and
actuation forces. Examples of
these switch types are
membrane, scissor, and
mechanical.

5. 3. Circuit board
 The circuit board, sometimes called the
printed circuit board or PCB, is the
structural component that joins
switches

6. 4. Backplate
 Some keyboards use plate-mounted switches or a backplate to
provide additional stiffness and stability to the keyboard
building, which makes the design more sturdy and secure.

7. 5. Cables and
connections
 Cables and connections: Keyboards are outfitted
with connections and wires, forming a technical
tapestry that connects them to computers.
Whether they are USB, PS/2, or wireless
connections, these wires create an art form of
smooth communication. Advanced wireless
keyboards might include additional features like
Bluetooth modules that are ethereal.

8. Categories of Buttons on
Typical Keyboard
1. Alphabet and Punctuation Keys
2. Number, Symbol Keys, and Numpad
3. Special Keys
4. Function Keys
5. Toggle Keys
6. Navigation Keys
7. Modifier Keys

9.  The QWERTY layout of the
keyboard includes all 26 Latin
letters: period, colon, and
comma punctuation keys
located next to the letter keys.

10.  The keyboard’s ten numerical keys (0–9)
can also be symbols using the “shift”
button. The right side contains the
arithmetic symbols (+ and -). There’s also
a separate numpad on the right of many
keyboards.

11. The keys, such as space,
enter, backspace, windows,
escape, and delete,
provide unique functions.

12. 4. Function Keys
The top section of the keyboard
has 12 function keys, each serving
specific purposes like refresh or
developer tools and capable of
combining with other keys.

13. 5. Toggle Keys
 Three toggle keys can lock down specific
functionalities when pushed. For
instance, “Caps Lock” will input every
letter in uppercase. “Scroll Lock”
removes the ability to scroll, whereas “Num
Lock” turns off the numpad’s numerical
capability

14. 6. Navigation Keys
The arrow keys act similarly to a mouse by enabling
us to travel across any computer area. When the Num
Lock is on, the digits 8, 4, 6, and 2 on the numpad
alsofunction as directional arrows.

15. 7. Modifier
Keys
 Modifier keys are dependent keys that may
accomplish various tasks when combined
with other keys. These keys are called “Shift,”
“Control,” “Alt,” and “AltGr.” For instance,
typing “shift” with any letter will result in the
text typed in uppercase.
