What is a method of sending information from one device to another using removable media called?

The method of sending information from one device to another using removable media is known as Sneakernet. This term refers to the physical transfer of data by carrying removable media, such as USB drives or external hard drives, from one computer to another. Despite the advancements in network technologies and wireless communications, Sneakernet remains a viable option in situations where a direct network connection is unavailable or impractical, such as in isolated environments or for transferring large amounts of data.

The term is somewhat humorous and highlights the sometimes counterintuitive nature of using physical means for data transfer in an age when digital communication is overwhelmingly preferred. This method can also be secure, as it does not involve transmitting data over potentially vulnerable networks.

The other options represent various forms of digital data transmission. Wireless transmission refers to methods like Wi-Fi or cellular networks that allow for data transfer without physical connections. Bluetooth transfer is a short-range wireless technology used for connecting devices over small distances. Direct connection typically involves physically connecting devices through cables or networking equipment to enable data transfer, unlike the physical transfer used in Sneakernet.
