Computer cable adapters and splitters are especially important in that they help you cut down on expenses and efficiently assemble an ideal computer system. If you have two similar type devices, for example, you can either connect them with gender changer adapters, or send them the same signal by using a splitter. While there are some cable adapters that can change the gender on your cable end from male to female or from female to male, there are also cable adapters that let you have an extension cord for your peripheral device. A USB Hub, meanwhile, is an external adapter that allows you to prolong and multiply USB Ports. You will need to use an extension USB cable with it, but you can easily increase your USB ports externally with this adapter.
