I do think that a man should pay for the first date or two but after that the girl can pay now and then. For my relationship i pay in the winter time he pays in the summer. We do it this way because he does landscaping for a living. So in the winter time he doesn't work. This works out for us pretty well.
USB stands for Universal Serial Bus. USB is used to connect peripheral devices to a computer. Ethernet, on the other hand, is a high-speed networking protocol. It is used primarily to connect local area networks (LANs). Ethernet can also be used to connect a DSL or cable modem to a computer. The USB 1.0 specification supported speeds up to 12 megabits per second (Mbps.) USB 2.0 supports speeds up to 480 Mbps.
This is critical because a host controller or hub is designed to provide 5V DC power on one of the USB pins. Though not that common, A-A cables are used to connect USB devices with an A-style Female port to a PC or another USB device, and for data transfer between two computer systems. Note: Typically an A-A cable is not intended to connect two computers together or to connect a USB hub between two computers.
