Peripherals

Here I will show what they are and the function of some peripherals, you can take it as a purchase reference

1-Monitor/display

The computer monitor (in Latin America) or computer monitor or screen (in Spain) is the main output device (interface), which displays data or information to the user.

It can also be considered an input / output peripheral if the monitor has a touch or multi-touch screen.

The screen size is the diagonal distance from one vertex of the screen to the opposite, which can be different from the visible area when we talk about CRT, while the aspect ratio or aspect ratio is a measure of the ratio between width and height of the screen, for example a 4: 3 ratio (Four thirds) means that for every 4 pixels wide we are 3 high, a resolution of 800x600 has a 4: 3 aspect ratio, however we are talking about the proportion monitor.

These two measures describe the size of what is shown on the screen, historically until not long ago and like televisions, computer monitors had a 4: 3 aspect ratio. Later standards were developed for 16: 9 widescreen displays (sometimes also 16:10 or 15: 9) that until then we only saw in the cinema.

2- Mouse 

The mouse or mouse (pronounced / maʊs /) is a pointing device used to facilitate the management of a graphical environment on a computer. It is generally made of plastic, and is used with one of the hands. It detects its relative movement in two dimensions on the flat surface on which it rests, usually reflecting itself through a pointer, cursor or arrow on the monitor. The mouse can be connected wired (PS / 2 and USB ports), or wirelessly through a USB adapter that connects to the computer and receives the mouse signal, although it can also be through Bluetooth or infrared connectivity .
It is an essential input peripheral in a desktop computer for most people, and despite the emergence of other technologies with a similar function, such as the touch screen, practice still shows its useful life.

4-Headset

Headphones are a pair of small loudspeaker drivers worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear. Headphones are also known as earspeakers, earphones or, colloquially, cans. Circumaural ('around the ear') and supra-aural ('over the ear') headphones use a band over the top of the head to hold the speakers in place. Another type, known as earbuds or earpieces consist of individual units that plug into the user's ear canal. A third type are bone conduction headphones, which typically wrap around the back of the head and rest in front of the ear canal, leaving the ear canal open. In the context of telecommunication, a headset is a combination of headphone and microphone.
