The tips of Hollywood Clapper serve what main purpose?
It is quite common for computer users around the world to expand the capacity of their computers with USB extensions. Need to update your Wi-Fi network? You can plug and play as you like to improve speeds with a USB solution. You need to read SD cards on your laptop, but you do not have a built-in player? There is also a USB solution.
These small USB hardware extensions of your computer are called dongles. The etymology of the term is not clear, but it was suggested that it was a corruption of the word "hang" since the first computer dongles were hanging from the PC ports to which they were attached .
The original dongles were security-oriented: the dongle functioned as a hardware key for the computer itself or software. Although these types of dongles still exist, their use has been largely overtaken by general hardware dongles, which can increase the hardware capabilities of the user's computer at a lower cost.
