30) SBC reduced board computers (Arduino, Raspberry Pi, Orange Pi, Banana Pi)

         -Arduino: The designs of Arduino boards use various microcontrollers and microprocessors. Generally the hardware consists of an Atmel AVR microcontroller, connected under the configuration of "minimum system" on a printed circuit board to which you can connect expansion plates (shields) through the arrangement of the input and output ports. present on the selected plate.

         -Raspberry Pi: is a low-cost computer, single-board computer or low-cost single-board computer (SBC) developed in the United Kingdom by the Raspberry Pi Foundation, with the aim of stimulating computer education in schools.

         -Orange Pi: is a single-board open source computer, based on Raspberry Pi1 but lower priced and manufactured by Shenzhen Xunlong Software CO., Limited. It can work with Android 4.2, Android 4.4, Ubuntu, Debian, Fedora, Raspbian, ArchLinux, openSUSE, OpenWrt and other operating systems. It uses the AllWinner A20 SoC processor, and has a memory that goes from the 256MB of the Orange Pi Zero to the 2GB DDR3 SDRAM of the larger boards. It has a standard TF card slot.

         -Banana Pi: The Banana Pi is a small plate similar to the Raspberry Pi but with a more powerful processor and 1 GB of RAM. It is based on an Allwinner A20 capable of running Android, Lubuntu or Raspbian for example. It is a small plate lena of characteristics for those who want to take advantage of all its power.

29) Toner, Cartuchos, Sistemas de Tinta Continua.

29) Toner, Cartridges, Continuous Ink Systems.          -Toner: Toner, also called dry ink by functional analogy with ink, is a fine powder, usually black in color, which is deposited on the paper to be printed by means of electrostatic attraction or magnetography. Once the pigment is adhered, it is fixed on the paper, by means of pressure and adequate heat.          -Cartridge: An ink cartridge or inkjet cartridge is a replaceable set of a printer that contains the ink and, often, also the printhead itself that projects the ink on the paper during printing. The name derives from the fact that it corresponds to a hard container that is inserted inside the machine and that contains ink either on the basis of water or a special solvent.          -Continuous ink system: A continuous ink system, in English Continuous Ink Supply System (CISS), also known by the names inkjet in bulk, or simply Bulk kit (in English, "in batch"). A continuous ink system has many advantages that have made it popular in many countries around the world: The cost of ink is reduced, compared to the continuous replacement of cartridges, it has little maintenance (only in the case that the cartridge is damaged, it must do a deep maintenance). Another important advantage is that you can continue to recharge the tanks as many times as necessary, if the head is not damaged

28) Impact printers (Matrix, Non-Matrix), without impact (thermal, deinjection or inkjet, laser). -Matrix impact printers

28) Impact printers (Matrix, Non-Matrix), without impact (thermal, deinjection or inkjet, laser). -Matrix impact printers: The dot matrix printer or dot matrix printer is a type of printer with the print head that moves from left to right printing on the page by impact, pressing an ink ribbon against the paper, so similar to the operation of a typewriter. Unlike the typewriters or margarita printers, the letters are obtained by selecting points from a matrix, and therefore it is possible to produce different fonts, and graphics in general. -Non Matrix Impact Printer: print without impact. This is the name given to printing made by a set of devices, generally connected directly to the computer, that generate the image without the printer form touching the support. Examples are: laser, thermal, inkjet, sublimation, etc. -Termica: The thermal printer is based on a series of hot needles that run through the thermo sensitive paper, which on contact becomes black. -Injection: Inkjet printers work by ejecting ink droplets of different sizes on paper. They are the most popular printers today for the general public because of their ability to print quality at low cost. -Laser: the printing device consists of a photoconductive drum attached to a toner deposit and a laser beam that is modulated and projected through a specular disc towards the photoconducting drum. The rotation of the disk causes a sweep of the beam on the generatrix of the drum. The zones of the drum on which the beam impinges are ionized and, when those zones (through the rotation of the drum) pass through the toner deposit, attract the ionized powder from it. Subsequently the drum comes into contact with the paper, impregnating the corresponding areas with dust. Finally, the ink is fixed to the paper by means of a double action of pressure and heat.

27) Stabilizers, UPS, IEC connector.
-A voltage stabilizer is an electronic or electromechanical equipment, designed to give a stabilized voltage at its output (230 Volts or 380 Volts), although at its input the voltage is lower or higher than the utilization value.
-UPS: it is a source of electrical supply that has a battery in order to continue giving energy to a device in the case of electrical interruption. UPSs are called in Spanish UPS (Uninterruptible Power System). UPS stands for Uninterruptible Power Supply in English.
- IEC Connector: (International Electrotechnical Commission) is the common name of the set of thirteen electrical power connectors and thirteen plug panels, defined in the IEC 60320 specification (formerly IEC 320) of the International Electrotechnical Commission (IEC).

26) Wired and Wireless Keyboard and Mouse (USB, PS / 2, Bluetooth, Wifi). - WIRED KEYBOARD: It is an input peripheral or device, partly inspired by the keyboard of the typewriters, which uses a set of buttons or keys, to act as mechanical levers or electronic switches that send information to the computer. - WIRELESS TUNING: They are usually common keyboards where the communication between the computer and the peripheral is done through infrared rays, radio waves or by bluetooth. -MOUSE WIRELESS: It is a pointing device used to facilitate the management of a graphic environment on a computer. It is usually made of plastic and is used with one of the hands. It detects its relative movement in two dimensions by the flat surface on which it rests, usually reflected through a pointer or arrow on the monitor. -MOUSE WIRELESS: In this case the device lacks a cable that communicates with the computer (computer), instead uses some type of wireless technology. For this, it requires a receiver that receives the wireless signal that produces, through batteries, the mouse. The receiver is normally connected to the computer through a USB or PS / 2 port.

25) Joystick, Control Controls, Headbands, Microphone.

25) Joystick, Control Controls, Headbands, Microphone.
- JOYSTICK: It is a device of control of two or three axes that is used from a computer or videoconsola until a space shuttle or the fighter planes, happening through cranes.
-CONTROL CONTROL: It is an electronic device used to perform a remote operation (or remote control) on a machine.
The term is generally used to refer to the remote control (usually called simply "the command" or, in Latin America, "the control") for the television or other type of home electronic device, such as DVD, Hi-Fi, computers , and to turn on and off a switch, alarm, or open the parking door.
-ADADEMAS: There are so-called headband microphones that are those, which, as the name implies, adhere to the head like any headband, which allows the user greater comfort no longer need to hold it with their hands, which allows perform other activities.
-MICROPHONE: The microphones are the transducers responsible for transforming acoustic energy into electrical energy, allowing, therefore, the recording, storage, transmission and electronic processing of audio signals. They are dual loudspeaker devices, both transducers constituting the most significant elements in terms of the sonic characteristics that superimpose the audio signals

24) Reading and Burning Units (CD, DVD, BlueRay). READING UNITS: -CD: The CD-ROM drive allows the use of optical discs with a higher capacity than 3.5-inch floppy disks: up to 700 MB. This is its main advantage, since CD-ROMs have become the standard for distributing operating systems, applications, etc. The use of these units is very widespread, since they also allow to read compact audio discs. -DVD: DVD-ROM drives are apparently the same as CD-ROM drives, they can read both DVD-ROM and CD-ROM discs. They differ from the CD-ROM reading units in that the support used has up to 17 GB capacity, and in the speed of reading the data. The speed is expressed with another number of the "x": 12x, 16x ... But now the x refers to 1.32 MB / s. Thus: 16x = 21.12 MB / s. -BLUERAY: It is a device that mounts in the bays of 5.25 "of the cabinet, basically integrates within itself a special blue laser beam emitter to read the data recorded on a CD (" Compact Disc "), on a DVD (" Disc Versátile Digital ") and the DB (" Blu-ray Disc "), a motor to rotate the disc and a tray to place them.After reading the data, this unit is also responsible for sending them by means of a cable to the main card (Motherboard) to be processed. BURNER UNITS: -CD: CD burner is a device that will record data or any type of information on an empty optical compact disc. There is also the CD Rom device that only does the work to read the compact disc. The CD Rom is an optical disc. The maximum possible memory that can be stored in an empty device is approximately 800 super bytes. The CD burner comes along with the set of a serial bus that can be connected to the system and there will also be a driver software that can be used to burn the Rom. -DVDRW: It can read and record and re-record images, sound and data on discs of several gigabytes of capacity, with a capacity of 650 MB to 9 GB. -BLURAY: The unit opens and closes its tray either through the user by the button assigned to it or from the computer software. Once placed the Blu-ray, DVD, HD-DVD or CD and the tray inside, an internal mechanism couples the disc with the laser beam and the motor begins the turn to read the characteristics of the disc
