1394 Cables have 9 pins on one end and 4 pin or 6 pin connector at the other end to connect a 1394a device to a 1394b computer port to run at a slower speed.
9-pins 9 pins at one end and 4 or 6 at the other. (pg. 407)
"Wi-Fi" is the trade name for the IEEE 802.11 standard. the name is used to sell the product , much like the term "Firewire" (IEEE 1394).
This is the port IEEE 1394 is also known as Fire Wire
There are multiple interfaces / cables that have been used to connect printers to a computer, each with a different number of wires. USB, for instance, has only 4 wires, while IEEE 1284 (parallel / Centronics) has 25 pins, although not all of them are always used for all printers. IEEE 1394 (FireWire) has either a four or six-wire cable, while the ADB (Apple Desktop Bus) port used 4 wires.
From Wikipedia definition of IEEE 1394 Standard - "The IEEE 1394 interface is a serial bus interface standard for high-speed communications and isochronous real-time data transfer, frequently used by personal computers, as well as in digital audio, digital video, automotive, and aeronautics applications. The interface is also known by the brand names of FireWire(Apple), i.LINK (Sony), and Lynx (Texas Instruments). IEEE 1394 replaced parallel SCSI in many applications, because of lower implementation costs and a simplified, more adaptable cabling system. The 1394 standard also defines a backplane interface, though this is not as widely used."

RS-232 is a standard for serial communication that defines the electrical characteristics and timing of signals, commonly used for connecting computers and peripherals. IEEE 1394, also known as FireWire, is a high-speed interface standard for connecting devices like cameras and external drives, allowing for data transfer rates up to 800 Mbps or more. The IEEE 1248 standard, related to electrical connectors, specifically addresses the specifications for connectors used in telecommunications and networking applications. Each of these standards serves different purposes in facilitating communication and connectivity in electronic systems.
FireWire, also known as IEEE 1394, was developed by Apple Inc. in the late 1980s. The technology was designed for high-speed data transfer and is commonly used for connecting digital devices like camcorders and external hard drives. The standard was later standardized by the Institute of Electrical and Electronics Engineers (IEEE) in 1995.

168 pins are used on SDRAM DIMM. 184 pins are used on DDR DIMM. There are either 30 pins or 72 pins used on SIMM. 184 pins are used on RIMM.
According to IEEE the 802STANDARD is used for LAN Standard.
