What is a Keyboard?

What are Keys?

• Keys are like tiny buttons on a special board called a keyboard. Each key has a letter, number, or special symbol. It's like having a magic set of buttons that help us talk to the computer.
• Example: When you press the 'A' key, it shows the letter 'A' on the computer screen.

Letters, Numbers, and More:
The keys have letters from A to Z, numbers from 0 to 9, and special keys. Special keys on a keyboard serve various functions and can make using a computer more efficient. Here's a brief overview of the uses of different special keys:

• Shift Key: Makes letters BIG or helps type symbols above numbers.
• Caps Lock: Makes all letters BIG until turned off.
• Tab Key: Helps create spaces or indents in writing.
• Enter/Return Key: Starts a new line or sends information.
• Backspace Key: Erases the letter behind the blinking line.
• Delete Key: Removes the letter in front of the blinking line.
• Arrow Keys (Up, Down, Left, Right): Move around like magic arrows on the screen.
• Ctrl (Control) Key: Helps do special tricks when pressed with other keys.
• Alt Key (Alternate): Does different jobs with other keys.
• Windows/Mac Key: Opens important menus or does special things.
• Function Keys (F1-F12): Each does a different job in programs.
• Spacebar: Makes spaces between words or plays/pauses things.
• Ctrl+Alt+Delete: Opens a special menu on Windows computers.
• Print Screen: Takes a picture of what's on the screen.
• Esc (Escape) Key: Stops or closes things, like magic exit button.

Understanding these keys helps you use the computer easily!

• It's like a special board that can type anything we want!
• Example: If you want to type your name, you press the keys for each letter of your name on the keyboard.

Talking to the Computer:

• The keyboard is how we talk to the computer. When we press a key, it's like telling the computer what we want it to do - whether it's playing a game, writing a story, or searching for fun pictures.
• Example: Pressing the space bar key helps you put spaces between words when you're writing a sentence.

Taking Care of the Keyboard:

• We need to be gentle with the keyboard, just like with our toys. No banging or spilling things on it! We want our magic talking buttons to stay clean and work properly.
• Example: Before using the computer, make sure your hands are clean, so the keys stay nice and shiny.
