The mouse or mouse is a hardware of the peripheral type (input device), used in computing to carry out various actions, and indicate orders through the operating system . When the mouse is connected, the screen presents an arrow-shaped cursor that will allow the user to interact with the interface, pointing to the instructions that they want to activate.The mouse is generally made up of a right button and a left button , and at present it is complemented from the factory with a central button and a scroll (roller for scrolling), with which the user can have an optimal productivity experience, interacting with the computer programs by means of the cursor.The mouse is an essential accessory to be able to work with computer equipment and technology that manages a visual environment for its handling. This input device can be found in so many modes, including mechanical and optical mice, mouse pens or pens, and touch ball mice, among others.

What is the mouse for?

The mouse provides the user with functions that allow him to perform the desired functions on the computer.

It serves to:

  • Open and close pages, folders, and programs
  • Minimize and maximize pages, folders, and programs
  • Select texts to highlight them
  • Select files
  • With a sustained click, move files and documents
  • Make it easy to find files by moving between folders with clicks
  • Increase and decrease the volume of the audio in multimedia programs
  • Facilitate the use of a variety of programs (by pressing their virtual buttons)
  • Playing and directing video games on the screen
  • Orient and move the cursor to meet user goals
  • Use drawing tools in editing software
  • Modify text, indicating with a click the place where it is necessary

Facilitate the management of programs and applications

Files, pages, and documents can be opened and closed using the mouse in graphical operating system environments such as Windows, OS, and Linux.

With the mouse we can select several files at the same time , in two ways:

  • By clicking with the left button on a free area and, while holding it, move it to cover the files you want.
  • Left-clicking on a specific file and, holding the Ctrl key, click in the same way, on each file, one by one.

Execute actions with one click

The mouse provides the user with an interactive experience with the computer.

Searching for diverse files or documents is much easier using the mouse, than if we did it with the keyboard, for example. In the graphical environment, the mouse allows us to move through the internal programs and devices (such as hard drives) and external (USB and SD memories, external hard drives, DVD and others), to explore and select the information.

Thus, the content of the storage units can be known, which can range from music, documents, programs and other executables that are useful for our work on the computer.

Work with programs

Thanks to the mouse, the user can easily manipulate programs such as video editing, images, games and the Internet. We can take advantage of it in so many ways, such as:

  • As a controller for video games
  • To perform program execution commands, by clicking a button or dragging elements according to our criteria and needs.

Draw and edit images

We can draw and edit images with great ease in specialized image editing and design programs . The mouse provides complete maneuverability that allows us to address details and specifications of the edition, making the most of the tools of these software.

Modify texts

Editing text in word processors, such as Wordpad, Abiword, Works, Microsoft Word, notepad and others, is easier thanks to the fact that with the mouse we can:

  • Locate and move the writing cursor
  • Select texts to highlight them
  • Move place texts
  • Cut fragments of texts
  • Copy fragments of texts
  • Delete fragments of texts

Playing video games

Many computer games do not have suitable devices to use, such as the joystick. Being an accessory that is easily used with one hand, the mouse is adaptable to the functions of the video game. It is enough to include its scrolling and selection functions for a complete interaction, which if required can be complemented with the keyboard.

Mouse evolution

The mouse has had different settings and connections.

These devices have been technologically developed since more functions and buttons have been added to them; However, one of the most notorious aspects of their evolution has been the type of connection with which they are designed:

  • RS-232 type cable, the oldest
  • Cable with PS / 2 connection
  • USB cable connection
  • Wireless mouse via infrared or other systems

In the same way, the presentations in which they are sold have varied, labeled or ergonomic, or according to market trends.

Mouse operation

Mice, generally classified as mechanical and optical , have different modes of operation, which are described below.

The mechanical or traditional mouse may function through a system of rollers , which are driven by a solid ball located therein . It is by means of these rollers that the sensors that transmit the movements are activated, converting them into signals that the computer translates as orders and movement of the cursor.

In the case of optical or light mice , the work of detecting movements is carried out by optical sensors, which are later translated into logical orders, interpreted by the computer as displacement.

In both types of mouse, instructions are indicated through buttons and transmitted as electrical impulses to the computer, which ultimately executes them for the user.
