An extension cord (also known as a power extender or an extension lead) is a length of flexible electrical cable (flex) with a plug on one end and one or more sockets on the other end (usually of the same type as the plug). The term usually refers to mains extensions but is also used to refer to extensions for other types of cabling.
A power strip is a block on the end of a cable with a number of sockets (usually 3 or more), often arranged in a line. This term is also used to refer to the whole unit of a short extension cord terminating in a power strip.
An extension reel is an extension lead that rolls up, usually into the socket end, which in most cases has more than one socket on it (often 2 or 4).
A power cord is similar but the socket end is designed to mount with a panel plug (usually IEC or figure 8 style) and is usually much shorter.
Extension cords may refer to cables that transmit data, electricity, or both (e.g. USB extension cable).
The USb signals going in and out of the extensioncable are bufferd to assure signal quality and the meeting of the USB Electrical and Timing Specifications.
