You probably know what a USB port is. You plug stuff into it, and it works.
But did you know that a smartphone can operate multiple different types of devices simultaneously?
OTG Meaning
USB OTG, short for USB On-The-Go, is a technology that enables direct connections between your smartphone or tablet and other devices, using a cable with a phone connector on one side and a USB-A connector on the other, for connecting to peripherals like external hard drives.
What is an OTG cable?
An OTG (On-The-Go) cable allows a smartphone to connect and interact with devices like keyboards, cameras, and hard drives, acting as a data access and transfer host. This specialized USB cable is designed for smartphones, supporting both powered and unpowered connections.
You can connect just about anything else to a smartphone via a special connector called an OTG cable.
This includes mice, keyboards, digital cameras, external hard drives, printers, speakers, and even scanners.
OTG cables work similarly to regular USB ports, but they’re designed specifically for smartphones.
They allow your phone to act as a host while still allowing you to access data stored on another device.

Peripheral
A peripheral is anything external to the main components of a PC—the CPU, RAM, hard disk, motherboard, etc.—that you use to interact with it.
Peripherals are usually plugged into ports located on the front panel of the system case.
They include things like OTGs, USB drives, micro USB, tablet PC, printers, scanners, webcams, microphones, speakers, joysticks, gamepads, mice, keyboards, headsets, cameras, and even networking hardware.
Differences Between USB And OTG Connection Cables or Adapters
USB is the ubiquitous standard for connecting peripherals to computers.
OTG stands for “on the go,” and uses a different set of pins than traditional USB ports. These include four data lines, one power line, and a ground connection.
An OTG connector is used to allow mobile phones or PCs to act as hosts, allowing them to connect to external storage devices such as hard drives and flash drives. In fact, most smartphones today come with an OTG port built into the side of the device.
A female connector is connected to the PC or Mac while a male connector is connected to the phone. This allows for data transfers between both devices, making it easy for you to transfer files and access media from one device to another.
A male micro USB connector is also available on some models of OTG cables, which connect directly to your device without needing an adapter.
A fifth wire is optional, and some adapters don’t require it.
A USB OTG adapter is also available, which features a USB plug on one end and a female micro-USB port on the other.
This adapter allows you to connect your phone directly to another device and transfer data without having to go through cables or connectors. With this adapter, you can even use your phone as an external storage device for storing media files.
