Rate this post

When plug and play device was not there in the olden days, plugging something into your computer—a mouse, a printer, a hard drive—required a zoo of cables. There were ports of various sizes and shapes, each devoted to a single kind of peripheral—one for a mouse or keyboard, another for a printer, different sorts for joysticks, modems, and sound gadgets.

They were formed differently and based on unique protocol. These ports additionally restricted the quantity of devices users could attach to their PCs; to add another printer, users needed to remove the first. And there was no space to plug and play devices, for example, scanners, cameras, and external storage drives.

History of Plug And Play Device

Today, the least techie customer can connect printers, scanners, cameras, and other peripheral gadgets to PCs by connecting them to the pervasive USB (Universal Serial Bus) ports found on each platform. However, in the mid-1990s, things were not “plug and play.”

In any case, if you needed to attach more advanced plug and play devices, for example, a scanner, you needed to open up the PC and plug in a SCSI card, and there was much confusion for end-users about how to do this.

A small group of organizations, prodded by Intel, was soon united to find the solution: The Universal Serial Bus (USB). This facility was presented in 1996 and omnipresent in PCs. Today, it empowers users to attach the different plug and play devices, from printers and cell phones to scanners and storage drives, utilizing a single, standardized interface socket.

USB empowers “hot-swapping”—connecting and disconnecting plug and play devices without the need to turn off or reboot the computer, and the process to the same was known as “plug and play.”

With the evolution of USB, users finally had a simple solution for connecting peripheral devices. The popularity of subsequent “plug and play” solutions can be attributed to the success of USB’s simple interface.

What is Plug And Plug Device

Microsoft created a plug and Play specification with collaboration from Intel and other equipment manufacturers. The objective of Plug and Play devices is to make a PC whose hardware and software operate together to automatically configure gadgets and allocate resources to permit hardware changes and additions without the requirement for large-scale resource assignment tweaking.

With these gadgets’ help, you can connect another device and promptly use it, without complicated steps.

The option of a plug and play device was presented in Windows 2000. One can plugin, for example, a USB device, and it is recognized and accepted by the computer to be used without rebooting the Pcs.

The operating system has drivers for almost every type of device. When a gadget for which the operating system has the driver is connected, the communication between the driver and the device is set up by the OS.

For example, these peripheral devices, network connectors, sound cards are associated with expansion slots inside the PC. Different devices, for example, printers and scanners, are attached to ports outside the PC. A few gadgets such as PC Cards attach only to PC card slots on a compact PC. The operating system nearly has the device drivers for all type of plug and play devices.

Some Examples of Plug and Play Devices

Today, there is a wide range of plug and play devices available for computers. Following is a list of some of the more common ones.

  • External hard drive
  • Computer monitor
  • Keyboard
  • Gamepad or joystick
  • Mouse
  • USB flash drive

How to use Plug and Play Device?

For Plug and Play to work, a PC must have a three-way similarity between the OS, the BIOS, and the Plug and Play part.

This decent thing about Plug and Play is that you can’t see the entirety of that as a user. You plug in new gadgets, and it begins working. The operating system consequently identifies the change, and the system analyzes the new hardware’s data to perceive what it is.

When the plug and play device type is recognized, the system loads appropriate programming (called device drivers) to make it work. At this point, it assigns resources, settles conflicts, arranges settings, and informs different drivers or uses of the new devices, so everything operates together. This is finished with the least user involvement.

Some plug and play devices, for example, mice and keyboards, can be completely functional through Plug and Play. Others, for example, sound cards and video graphics cards, require installing the product’s incorporated programming to finish the auto-configuration. This generally needs only a few clicks to begin the installation cycle, trailed by a moderate wait for it complete.


Plug and Play devices will make updating our PC so simple that even a kid can undoubtedly do it. At the point when Windows 95 was first launched, Microsoft wanted us to accept that the Plug and Play service (aka Plug and Pray) would end all of our device driver issues, and it did as well.

This idea of plug and play device is intended to end the days of manual device configuration and driver clashes, giving non-IT PC users the capacity to update their PC without any problem. The objective was to make ON a PC with no Operating System, when a user connects any USB, and connect any peripheral device easily so that anybody can use it.
