Such parts of the computer that accept inputs play a very important role in the computer. With their help, we interact with the computer, give commands, and perform different tasks.
Just as people speaking different languages interact, they need a translator to understand each other. In the same way, we provide inputs to the computer to convey our message and perform the task.
Today, we will try to understand the three parts of a computer that can accept input.
No 1: Keyboard
These are all the most commonly used input devices. We provide data to the computer using different keys. It is the most common and well-known input device. A signal is generated when you press a key, giving the computer a command which key you pressed.
How Does the Keyboard Work as an Input Device?
The computer does not understand letters directly. When you press a key, a signal is generated. The computer interprets that signal and displays the corresponding letter on the screen.
If you press “U,” the computer will interpret it and show you ‘U’ on the screen.
Types Of Keyboard
There are different types of keyboards, and some of them include the following:
- First, let's consider the mechanical keyboard. In this type, each key is clearly separate. Every key produces its sound when you press it. These keyboards are used mainly by people who do a lot of typing and gaming.
- Ergonomic keyboards are designed in a very special way. They are in a curved shape. These are designed for those who do a lot of typing because it is said that they do not cause wrist injuries.
- Some keyboards are connected to the laptop without any wires. They are known as wireless keyboards. You can connect them to the computer using any Bluetooth device. The benefit is that you do not have to sit stuck at one place instead of wires. You can type even while sitting at some distance from the laptop.
Purpose of Keyboard
Keyboards can be used for different purposes. We give commands to the computer through them and enter data. We can type programs & search online.
Their primary purpose is to type. By typing, we provide input to the computer. They are also used for shortcuts like the Ctrl + V shortcut to paste copied text.
No 2: Mouse
A mouse is another input device that helps you interact with your computer. It has buttons and a wheel through which you move the cursor on the screen.
How does the Mouse Work As an Input Device?
When you move the mouse, a device detects the movement and makes the cursor on the screen move in the same direction. Each mouse button tells the computer to do something specific when you click it, like opening a document or highlighting a text section.
Types of Computer Mice
Many people use mice in a wide range. Considering the needs of many people, many different types of mice have been made. We have seen some mice working in it.
- Let's start with the wireless mouse. The wireless mouse is connected to the laptop or computer through radio signals. It provides a fast and reliable experience. It is very easy to use, and you do not have to worry about wires.
- Like the wireless mouse, there is also a Bluetooth mouse. These mice are connected to the computer through a Bluetooth device. These are also wireless.
- It can be used even when sitting far from your computer or laptop. For example, if you are sitting away from the computer and watching a movie or video, you can control the screen by clicking on it.
- Just like there are ergonomic keyboards, there are also ergonomic mice. These are used to reduce natural hand pain. They come in different shapes and designs and are specifically meant for those who often use a mouse.
What is The Working of the Mouse?
With this input device, you can perform different functions. You can perform other actions by moving the cursor on the screen. You can drag and drop things. With the help of the wheel on this, you can scroll any website or document. With this, you can perform different actions.
For example, if you want to click on any button, you move the cursor to that button, and then if you right-click with the mouse, it will click on the computer button.
No 3: Microphone
It is less well known than the keyboard and mouse. But it is a beneficial input device. It captures voice and converts those signals into a form the computer can understand.
How Microphones Work As an Input Device?
When you speak into a microphone, the sound is captured and converted into electrical impulses. They are conveyed to the computer and converted to digital form, which responds by sending signals back.
For example, when you voice command a computer or record a podcast, the microphone lets you capture your voice and forward it to the computer.
Types of Microphone
- Condenser microphones are clear and highly detailed, so they are suitable for studio recording of vocals and other instruments. These microphones require phantom power to work, which is why they are called "phantom wattage." Their sensitivity records accurate sound changes in well-monitored conditions.
- Ribbon microphones have a smooth, flat type of diaphragm. They are best suited for vocal and brass instrument recording. These structures are delicate and should be handled with great care.
- Dynamic microphones are also quite sturdy and capable of dealing with loud sound pressures, which makes them useful for live performances and podcasting.
They are stable and exhibit minimum failure rates in noise-filled conditions.
Different Purposes of Microphone
Microphones have various uses, such as recording music, making clear voice calls, and giving audio commands to a computer.
They enable voice interaction, which is especially helpful for people who find typing difficult. Microphones are also used in voice recognition systems, allowing the computer to understand and follow spoken instructions.
Conclusion
The keyboard, mouse, and microphone are three major components of the computer that can receive input. These advanced devices help you communicate with your computer and perform several activities.
Understanding these input devices will help you use your computers more effectively and optimize your interaction. By typing a document, a web page, or even dictating a voicemail, these input devices are vital for efficient computing.
