Input type

A keyboard and a mouse give input to the computer in different ways. They both help us, but they work differently.

Keyboard

The keyboard lets us type letters, numbers, and symbols. We press the keys to give input. Each key sends a signal to the computer. This helps us write words, give commands, and do many tasks.

Mouse

The mouse helps us move the cursor on the screen. We click, drag, and scroll to give input. The mouse tells the computer where to go. It is great for pointing, selecting, and opening things.

Main function

Every device has a main job. The keyboard and mouse help the computer in different ways.

Keyboard

The keyboard’s main job is typing. We press keys to write words and numbers. It helps us talk to the computer using letters. Without it, we cannot write anything.

Mouse

The mouse’s main job is pointing. We move it to control what’s on the screen. It helps us click, open, and move things. Without it, we cannot select or drag items.

Number of keys or buttons

The keyboard has many keys, but the mouse has only a few buttons. That’s a big difference.

Keyboard

A keyboard has many keys. These keys have letters, numbers, and symbols. Some keys are also for special tasks like space, enter, or delete. We use different keys for different actions.

Mouse

A mouse has two or three buttons. Most mice have a left button, a right button, and a scroll wheel. We use the buttons to click, select, and scroll. It is easy to control things with these buttons.

Shape and design

The keyboard and mouse look very different. You can easily tell them apart just by their shape.

Keyboard

A keyboard is long and flat. It looks like a small board with many keys on it. You usually place it in front of the computer screen. It stays in one place while you type.

Mouse

A mouse is small and round or oval. It fits in your hand. You move it around on a table or a mouse pad. It’s made for easy hand movement.

Usage style

We use the keyboard and mouse in very different ways. Both need our hands, but we use them differently.

Keyboard

We press the keys with our fingers. Our hands stay still, and only our fingers move. We look at the screen while typing. The keyboard does not move.

Mouse

We move the mouse with our hand. Our hand controls the pointer on the screen. We click and drag by moving the mouse. It needs space to move around.

Used for different tasks

We don’t use the keyboard and mouse for the same work. Each one helps with different things on the computer.

Keyboard

We use the keyboard to type names, answers, and messages. It helps in writing emails and doing homework. It is also good for using keyboard shortcuts.

Mouse

We use the mouse to click on folders, open games, or move pictures. It helps in drawing, dragging items, and playing many computer games. It’s great for selecting and pointing.

Speed of operation

We use the keyboard and mouse in very different ways. Both need our hands, but we use them differently.

Keyboard

We press the keys with our fingers. Our hands stay still, and only our fingers move. We look at the screen while typing. The keyboard does not move.

Mouse

We move the mouse with our hand. Our hand controls the pointer on the screen. We click and drag by moving the mouse. It needs space to move around.

Need for surface

Some devices need space to work. The keyboard and mouse are not the same in this way.

Keyboard

You can keep the keyboard on any table. Once you place it, it stays there. You don’t need to move it while typing.

Mouse

The mouse needs a flat surface to move on. You cannot use it in the air or on a soft bed. It works best on a smooth table or mouse pad.

Input accuracy

Some tasks need very correct input. A small mistake can cause a big problem. That’s why accuracy is important.

Keyboard

The keyboard gives exact input if you press the right key. But one wrong key can change the whole world. For example, typing “cat” as “bat” gives a wrong result.

Mouse

The mouse also needs correct clicks. If you click the wrong icon, you may open the wrong file. But still, it is easier to fix mouse mistakes by clicking again.

Common types

The keyboard and mouse come in different types. Some are old, and some are modern. Let’s see the most common ones.

  1. Wired Keyboard: It connects with a cable.
  2. Wireless Keyboard: It works without a wire.
