Techopedia explains Lightning Connector. The Lightning connector was a successor to the previously used 30-pin connector. It is a small wire with a USB 2.0 interface at one end and a connector plug at the other. The connector consists of a communication bus for dual data transfer; it also provides electrical power to the device.
A modular connector is an electrical connector that was originally designed for use in telephone wiring, but has since been used for many other purposes. Many applications that originally used a bulkier, more expensive connector have converted to modular connectors. telephone-system-standard RJ45 plug has a key which excludes insertion in an un-keyed 8P8C socket. The registered jack (RJ) standard specifies a different mechanical interface and wiring scheme for an RJ45S from TIA/EIA-568-B which is often used for modular connectors used in Ethernet and telephone applications.
