What is a Mouse in a Computer & How Many Types of Mouse

The mouse is an input device . It is a pointing device that is used to interact with the PC. Mouse is mainly used to select different items on the computer screen, learn about them and open and close them.
Using the mouse, the user instructs the computer to do something. Through this, a user can access the computer anywhere on the screen.
There are different models of mouse which have different features and connectivity , but almost all models have two mouse buttons and a scroll wheel.
The interface of the mouse is different, that is, the medium used to connect with the computer or any other system. Then let’s get further information about Mouse.

What is the full form of the mouse?

The mouse has a full form, Manually Operated Utility For Selecting Equipment .
The full name of the mouse will be something like this, ” manually operated utility for device selection “.

Mouse definition

The mouse is a small pointing device that a computer user uses by placing it on a desk surface.
With the help of this , point, select, click, drag, drop and scroll can be done on the display screen, while apart from this, it can be selected from that position to perform a two action.

By what name is the mouse called

The mouse is also called “Pointer”.

Who was the father of computer mouse?

The mouse is originally called the XY Position Indicator which is used in the Display System. Sun 1963 in Douglas Engelbart was the invention of the Mouse by.
Which used to work in Xerox PARC at that time. It became so famous at that time that today you can see this pointing device in all computers.

About the mouse

Here below, you will give people information about the functions of the mouse. This will make it easier for the user to use the mouse.
1. Move the mouse cursor – This primary function is to move the mouse cursor in the screen.
2. Using Open or execute a program – Mouse, user can open and execute any icon , folder, or any other program by clicking.
3. Select – Mouse can be used to select text, to highlight.
4. Drag-and-drop – Users can easily drag-and-drop a document.
5. Can hover over objects using Hover – Mouse. Hover means that when you bring the cursor over an object , then whatever information will be available in relation to it will show.
6. Using Scroll – Mouse, you can scroll down to see the big document completely.

Types of Mouse Interface

type of Mouse Interfaces

Over time, many different interfaces of the mouse also developed as technology advanced. Here I am going to inform you about some similar interfaces:

Serial Mouse

This is the oldest type of mouse in this list which is not working anymore, but you can see it in some machines in government offices.
It has a serial connector (a DE-9F D-subminiature ) and needs a free serial port to connect to the PC.
It is typically a corded-type mouse and takes power from the serial port to operate itself.
This serial mouse is also referred to as cold-pluggable , which means that one should connect with the computer only when the computer is switched off.

PS/2 Mouse

This PS / 2 mouse is the upper version of the serial mouse. People are more attracted to them by their arrival. They can still be purchased as many motherboard manufacturers are still providing PS / 2 port.
These are PS / 2 connector (Mini-DIN) circular and have 6 pins, due to their design they are only correctly aligned with the port and inserted. PS / 2 mice are also cold-pluggable .

USB Mouse

If we talk about now, then nowadays we use a mouse with USB interface which needs a free USB port. They are either corded or cordless / wireless. These are hotpluggable , in Serial and PS / 2 counterpart .
This means that you can also use them in the running condition of the computer, here there is no risk to this mouse or to the computer.

Wireless mouse

Cordless or wireless mice transmit data via infrared radiation or radio (that is, Bluetooth).
Here a serial or USB port is used to connect the receiver with the computer, or a built in part such as Bluetooth.
Modern non-Bluetooth wireless mice nowadays use USB receivers. While in some they can be stored safely within the mouse , there are also ” nano ” receivers, which are designed in such a way that are so small that they are always connected to your laptop or system. Occur.
These are the very latest variety of mouse that do not need cable to connect.
While some wireless mouses are connected via USB receiver, others are connected via B luetooth connection . This type of mouse is given power from the battery which is AA type.


If you use PC then you must have used mouse. You will find this Mouse in the right or outer direction of your keyboard.
It requires a little space to operate properly. Here, below you will give information about the basic parts of a mouse:

  • Left (main) button: This left button comes under the index finger of your right hand, which is the most main button. This button is used the most.
  • Wheel button: This is also called center or wheel, you can use this button like pressing the left and right buttons. This is mainly done to lower or roll up the screen.
  • Right button: We use this right button for special operations, apart from right-clicking it pops up shortcut or context menu.
  • Mouse body: Mouse is the size of a soap. You give the weight of your palm over this mouse body and use the mouse buttons with the use of your fingers.
  • Special buttons: Apart from this, there are many other special buttons in the mouse, which are used for Internet navigation and other specific functions.

What is a mouse touchpad called?

The touchpad of the mouse is called the trackpad, glide pad, glide point etc.

What is touchpad?

Touchpad is a type of input device in laptops and some keyboards. This allows the user to move the cursor with the help of his fingers. They can also be used in place of external mouse.

Types of Mouse

type of mouse

There are many types of mouse available in the market today, all have some different technology which differentiates each other in their function.

Corded Mouse

A corded mouse connects directly to the computer via a cable (serial, PS / 2 or USB). It takes power for its operation from the same port to which it is connected, which means that there is no need of external batteries in it.
Corded mice are more accurate because they do not have much issues such as signal interference or performance loss due to low-battery states.

Cordless/Wireless Mouse

A cordless or wireless mouse is called a mouse that does not have any cables and uses wireless technology to transfer data and connect to the computer.
This is very good for those places where you have problems with cord or cable, such as while traveling.
Batteries are required to operate this mouse. Due to the presence of batteries, it is also a bit heavy.

Mechanical Mouse

A mechanical mouse is also called a ball mouse which consists of a ball and many rollers to track the movement.
This type of mouse is typically of corded variety and is not as popular as optical mouse.
Its performance is very high but it needs special cleaning from time to time.

Optical Mouse

An optical mouse uses optical electronics to track the mouse’s position and movement. They are also rated as standard mechanical mice as they are more reliable than others and require less maintenance.
But their performance depends on the type of surface on which they are operated.

How the mouse works

This thing must have come in the mind of all of us that how these icons work. So let’s remove this problem from you too.

How Ball computer mouse works

As we roll our ball mouse on top of our desk, the ball below also starts to roll with its weight and two plastic rollers attached to it, which are linked, pushes forward with thin wheels.
One of these two wheels detects movements in the up-and-down direction of the wheel (such as the y-axis in a graph / chart paper); The second wheel would detect side-to-side movements (such as x-axis on a graph / chart paper) movements.
Now the question arises that how do these wheels measure your hand movements ? As you move the mouse, the ball moves the rollers, so rotate one or both wheels.
If you move the mouse straight up, then only the y-axis wheel will turn; Similarly, if you move it to the right, only the x-axis wheel will turn. Just like the angle in which you move the mouse, similarly the ball will move both wheels simultaneously.
A small brain item has also been used with it. Both the wheels are made of plastic spokes and as they turn, they speak repeatedly when they break a light beam.
The more the wheel turns, the more the beam will also be broken. Therefore, how many times that beam is broken, it has to be counted accurately to measure how much the wheel has turned and how much you have moved the mouse.
It microchip within the counting and measuring mouse, which sends all the details to the computer via cable. The software that is in your computer moves the cursor according to this data according to the need in the screen.

Ball Mouse Disadvantages

This mouse also has many problems. As such it does not work on all surfaces. Therefore it needs special mouse mat.
Even with this, even if you have a mat, the rubber ball and its rollers gradually become dirty due to which the x- and y-axis wheels repeatedly move around.
Therefore, they should always be kept clean. Another option is that you use optical mouse.

How does optical mouse work

An optical mouse works completely differently. There is an LED in the back of the mouse which shines above the desk.
This light bounces back directly above the backup off desk where there is a photocell (photoelectric cell), which is also mounted at the bottom of the mouse, which is located at a very short distance away from the LED . .
This photocell has a lens in front of it which magnifies this reflected light, so that the mouse accurately marks your hand movements.
As you move the mouse above the desk, similarly the patter of the reflected light also changes and the chip which is inside the mouse shows how your hands are moving.
Some optical mice also have two LEDs. One who shines above the desk and knows the movement. The second one is placed in the back of the mouse and it shows whether the mouse is working or not. The rest of these icons also work in the same way.

Optical Mouse Disadvantages

By the way, this optical mouse is much better than the earlier ball mouse, but it also has some flaws such that it remains connected to the computer through a wire.
To operate with this, it needs something in its base so that it can work well with light reflection. And you cannot work it from far away because it is more than a wire.
This only increases the usefulness of the wireless mouse .

How the wireless mouse works

There is not much difference in the operation of this wireless mouse here compared to the optical mouse. They also detect movements in the same way as optical mouse.
The only difference here is in sending data to the computer. Here, there is transfer of data through a wireless connection in place of USB cable .
Here the power required to operate the mouse comes from external battery. All the operations of the rest of the mouse are similar to optical mouse.

Wireless Mouse Disadvantages

Its main disadvantage is that it requires external batteries to operate.
At the same time, if the battery runs out suddenly, then the user has a lot of trouble for the mouse. With this, it is also very heavy due to the battery. Apart from this, it is also the most expensive.

Mouse future

As advancement in technology is taking place, the mouse is also included in this line. Where earlier we used ball mouse, wireless mouse is still used.
Gradually, the use of the mouse may also stop, because with the increase of AI ( Artificial Intelligence ) , now the demand for voice commands has increased.
People need more facilities, they do not want to use their hands to do any work. In such a situation, the day is not far when the mouse will remain according to an ancient device.
But it is time for this to happen. Let us see what new things will come for us.
