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.
Why has a mini USB cable 5 pins and 'normal' USB cable 4 pins? Answer Wiki. This is to support the USB 'on the go' (OTG) specification. Traditionally a device with a USB port could only be a host (such as a PC) or a peripheral (such as a mouse or flash drive). The host device always provides power.
