Definition of Peripheral (informatics)

A peripheral is a physical electronic device that connects or attaches to a computer (or other computer device), but is not part of the basic core (CPU, memory, motherboard, power) of the same.

Peripherals allow put and/or get information from a computer.

Peripheral function

Peripherals are used to communicate the computer or computer device with the outside (mouse, monitor, keyboard, etc) or as information storage (hard disk, optical disk drive, etc.).

Peripherals can usually connect to different ports on the computer.In general, they can be connected or disconnected from the computer, but it would still work, although with less capacity.

Peripherals are part of the computer hardware, but not all hardware is peripheral (for example, the microprocessor, motherboard, etc.is hardware, but they are not peripheral).

Peripherals can with be wired (USB, serial, parallel, SATA, rj45, vga, etc.) or wirelessly (infrared, wifi, bluetooth, etc.)

Difference between peripheral and computer accessory

Peripherals are part of computer accessories or complements.

The term "computer accessory" includes peripherals, but also other components such as chips, motherboards, sensors, etc.Therefore, the word accessories is a broader term than peripherals.

Classification of Peripherals (according to their main data flow)

Peripherals can be input, output , storage or communication.

Input peripherals:

• Mouse (mouse)

• Keyboard

• Webcam

• Scanner

• Microphone

• Joystick, Gamepad, Flyer

• Optical pencil

Output peripherals:

• Monitor

• Printer

• Display

• Speaker (speaker)

• Graphics card

sound card

Input/output peripherals:

• Touch screen

• Virtual helmet

Communication peripherals (input/output ):

• Modem

• Network card

• Hub

They are storage peripherals (input/output):

• CD or DVD burner

• Zip

Definition of Macrocomputer (macrocomputer)

A macrocomputer is a large, powerful and expensive computer used primarily in companies that need to process large amounts of data or support large numbers of users.It contrasts with the concept of microcomputer (or microcomputer).Sometimes called macrocomputers. In English: mainframe and macrocomputer. For more information see: Mainframe What is a macrocomputer or mainframe? A large and powerful computer capable of managing a large number of simultaneous tasks and of communicating with a large number of connected terminals; used by large and complex organizations (such as banks and supermarkets) in which continuous operation is vital. Characteristics of macromputers Macrocomputers are a type of computer that are generally known Due to their large size, storage quantity, processing power and high level of reliability, they are mainly used by large organizations for critical mission applications that require large volumes of data processing.In general, there are some characte...

Definition of DPI or PPP (print quality)

(dots per inch, dots per inch).The DPI or PPP is a unit of measurement of the resolution of an image (related to quality) of a scanner, a printer, etc.It serves to measure the resolution, which is the amount of dots that enter an inch.It is expressed like this: (number) x (number) dpi. A resolution of 300 dpi will produce a text that will show broken lines visible under a magnifying glass.Even larger resolutions are necessary to obtain reproductions of smooth photographs.Professional graphics use printers with resolutions from 1200 to 2400 dpi. Pixels or resolution of a photo and printing in centimeters There is no direct equivalence between the pixels of a digital image and the centimeter of printing that correspond to it.A very small image can be printed very large on paper, but the pixels of the printed image will begin to be noticed at first glance.There are techniques to "enlarge" the digital image and soften it a bit the pixels, but these do not make ma ravillas. ...

Monoprogramming Definition

Monoprogramming, also called monoexecution, is an operating system in which only one program is executed at a time and no other is executed until the previous one is finished. In other words, only one program is executed at a time within a single address space. This type of execution practically does not exist anymore because it has been replaced by multiprogramming. Monoprogramming vs.multiprogramming In the monoprogramming, the memory only contains one program at any time, while in the multiprogramming the memory contains more than one user program. In the case of monoprogramming, when the CPU is running the program and it find an I/O operation (input-output), then the program goes to the I/O devices, during that time the CPU remains idle.Therefore, in the monogramming the CPU is not used effectively, that is, CPU utilization is poor. However, in the multiprog branch, when a user program contains I/O operations, the CPU changes to the next user program.Therefore, the CPU i...

Network transparency definition

Network transparency refers to the ability of a protocol to transmit data over the network in a way that is transparent (invisible) to those who are using the applications that use the protocol.In this regard, users of a particular application they can access remote resources in the same way they would access their own local resources. An example of this is cloud storage, where remote files are presented as if they were locally accessible; also the cloud computing where the resource in question is the processing. From English: network transparency. X Windows The term is often applied partially correctly in the context of the X Windows system, which is capable of transmitting graphic data over the network and integrating it seamlessly with the applications that are running and displayed locally; however, certain extensions of the X Windows system are not able to work on the network. Firewall In firewall technology, transparency can be defined in the network layer ( or IP) or ...

Definition of Spawning (video games)

(produce, generate).In computer games, spawning is the creation of an entity within the game, such as a player character, a non-player character or other item.Respawning is the recreation of an entity after its death or destruction , or at the end of a round. In a game, there may be different points of spawning or generation of characters or items.There may also be spawning of enemies; In many games enemy spawming is unlimited, however, the main player (s) usually has a limited number of spawning (the so-called "lives" of the player). Player spawning varies depending on the mechanisms of each game.It usually starts at the beginning of a round or after a player joins the game. Meanwhile, respawning usually occurs after a player was killed or destroyed, that can happen immediately or after a while (time in seconds, next round, etc.) Apparently the term was created by the company "id Software" during the development of the Doom game. In fact games like Doom, J...

Definition of Network Address Translation (NAT)

Network Address Translation, Network Address Translation and better known as NAT. Network Address Translation is a mechanism used by IP routers to exchange data packets between two networks that mutually assign incompatible addresses. It consists of converting, in real time, the addresses used in the transported packets.It is also necessary to edit the packets to allow the operation of protocols that include address information within the protocol conversation.

Initialization vector definition

In cryptography, an initialization vector (IV) is a block of bits required to achieve a flow encryption or block encryption, in one of the encryption modes, with a result independent of other encryption produced by the same key.p> The size of the IV depends on the encryption algorithm and the cryptographic protocol and is often as long as the block size or the size of the key.
