Have you ever used a USB for data transfer? I will tell you what it is exactly.
The USB (Universal Serial Bus) is an interface that allows data transmission between devices and a host controller such as a computer, laptops, and smartphones. It also connects peripheral devices, digital cameras, keyboards, printers, scanners, speakers, flash devices, external complex devices, etc.
What are USB Ports?
The function of the USB ports is to connect the devices to computers for storing or transferring the data between devices and charging devices. Plug in the USB cable to the Port for the connection. Your desktop or laptop will show you instructional messages.
Follow them and transfer your data. Some computers may damage due to unplugging your USB from the Port directly. It is better to eject the USB from the computer icon and physically unplug it.
There are different positions of USB ports in different devices:
- In desktop computers, USB ports are available on the front and back for convenience.
- In laptops, the ports you will find on both sides.
- In Tablets, you have a USB connection you will find in the charging Port.
- In Smartphones, the USB connection is also in their charging port like in tablets.
The connectors on the motherboard for extra USB ports in a PC are called USB headers. There are four types of USB headers used in computers around the world. For instance, a version 2.0 USB header is different from a 3.0 version. They are built according to the requirements.
Do you know how the USB works? When a device connected via a USB port, the computer will automatically detect the type of the device and load the driver that allows it to work correctly.

USB Header Splitter
There are several USB headers splits in the market. A USB Splitter is a wired device that connects other devices to a computer. It enhances the number of available USB slots that allow a computer to increase options or add functioning other devices such as printers, scanners, cameras, speakers, keyboards, etc., for users.
These USB header splitters are helpful in gaming when the gamer needs to connect with gaming accessories. A PC can support 127 USB ports simultaneously with the USB header splitter. For extra convenience, USB header splitters are safe to use on any computer device. This can affect the performance of the USB Hub as all the devices will share the bandwidth of the Hub.
Host, Port, and Receptor
Some other terms are important to understand. The slot which connects one end of the cable to a device is called Port. The thin side is connecting to the device. The Host is the device that transfers the data; the device that receives data is called the receptor.

USB Headers Hacks (Pro Tips)
There are different perspectives of the hackers and experts that show your computer can be hacked through the USB. You must be careful while using different USBs and cables.
There is a USB Killer device that can damage the computer. An inverting DC converter starts when you plug the USB into the port. It charges the capacitor to -110V. The field transistor opens concurrently. It is used to apply -110 V to the USB interface signal lines. The transistors stop working, and DC will be active with -7 V capacitor voltage.
USBDriveby is another hacker device that can hijack a computer within 30-60 seconds. It also disables passwords and security. Lastly, it enables remote manipulation for the computer. Keysweeper pretends to be a wall charger. They functioned to send SMS for the targeted words like a bank. USB password Stealer can steal the passwords present on the computers. To avoid any mishaps, you need to be careful about the physical access to your computer.
