A look a various peripheral devices used with computers

Since their appearance in the yearthese storage devices have gradually increased their storage capacity, while falling in price.

How to connect peripheral devices to computer

The rise of other technologies such as email and data storage devices have somewhat diminished the importance of printers in recent years. Projector Projectors are optical output devices that enable a roomful of people to see visuals generated by a single computer. Microphone Microphones are audio input devices. However, that isn't always true, so while some devices might be considered internal on one system, they could just as easily be external peripheral devices on another. Modern mice typically have two buttons, the left button and right button, with a scroll wheel in between the two. The first high-speed printer, developed by Remington-Rand, was used on the Univac computer. Technically mice are composite devices, as they both track movement and provide buttons for clicking, but composite devices are generally considered to have more than two different forms of input. The monitor essentially displays a signal sent by the computer in a visual format. Keyboard Keyboards are the most common input device. Printers A Printer is a device that takes in and process data which can be in the form of text and graphic and output the result to a usually A4 paper size. As well as computers, webcams can also be built into mobile phones. An output device reverses the process, translating the digitized signals into a form intelligible to the user.

Even today, Scanners are in constant evolution, currently offering high resolution output at a fraction of the cost and size of their predecessors. Even devices such as smartphonestablet computersand wearable devices like fitness trackers and smartwatches can be considered as peripherals, albeit ones that can function independently.

The first electronic printer to be invented was the EP, released by the Japanese company Epson in Altec Lansing claim to have produced the first commercially available computer speakers in Anything that you can connect to the outside of a computer, that typically doesn't operate on its own, could be referred to as an external peripheral device.

Updated April 18, 70 70 people found this article helpful A peripheral device is any auxiliary device that connects to and works with the computer to either put information into it or get information out of it.

They also include sensors that provide information about their environment— temperaturepressureand so forth—to a computer. Monitors look similar to televisions in outward appearance, but typically have a higher display resolution than televisions, enabling greater visual detail, plus they lack a tuner to change channels.

They act as the main text entry interface for most users.

Even today, Scanners are in constant evolution, currently offering high resolution output at a fraction of the cost and size of their predecessors. Keyboard Keyboards are the most common input device. Altec Lansing claim to have produced the first commercially available computer speakers in The rise of other technologies such as email and data storage devices have somewhat diminished the importance of printers in recent years. Since their appearance in the year , these storage devices have gradually increased their storage capacity, while falling in price. I go into more detail regarding each example below. Monitors are devices that receives video signals from the computer and displays the output information to the users. Then EARS saw the day.

Network interface cardsUSB expansion cards, and other internal devices that might plug in to a PCI Express or other type of port, are all types of internal peripherals. Input devices are machines that feeds data into the computer while output devices are machines that have the ability to represent incoming data from the computer.

Non peripheral devices

Composite Devices Wii Remote with attached strap Input devices, such as buttons and joysticks, can be combined on a single physical device that could be thought of as a composite device. It is a device which has an arrangement of keys and buttons that when using, act as an electronic switch. Many gaming devices have controllers like this. Technically mice are composite devices, as they both track movement and provide buttons for clicking, but composite devices are generally considered to have more than two different forms of input. Types of Peripheral Devices Peripheral devices are categorized as either an input device or an output device, and some function as both. These examples are just a few among lots of others. Early generation of computers were using those monitors. It was the ball mouse, which will later be replaced by the optical mouse. Another direct-entry mechanism is the optical laser scanner e. The Mouse The mouse is an important input device for all modern computers, especially those with graphical interfaces. It also had two metal wheels which were responsible for the functionality of the device, i. Input devices are machines that feeds data into the computer while output devices are machines that have the ability to represent incoming data from the computer. As with televisions, modern computer monitors use flat screen technology and have fallen in price in recent years. As their name suggests, projectors "project" still or moving images onto a screen, blank wall, or other surface.
