Step 1
Wireless connection
Answer
Wireless connection is a technology that enables computers and phones to share information without needing physical connecting cables. It operates by transferring data through radio waves, allowing devices such as laptops and smartphones to communicate and access information over wireless networks. This method eliminates the costs and complexities associated with managing cables, making it more convenient for users.
Step 2
USB key
Answer
A USB (Universal Serial Bus) key is a compact portable storage device that connects to computers via a USB port. It typically contains a flash memory component that enables data storage and transfer. USB keys are rewritable and much smaller than traditional storage devices like CDs or DVDs. Their design allows for faster data transfer rates and significantly greater storage capacity compared to older media formats, which enhances reliability due to the absence of moving parts.
