Parallel ports typically have 25 or 36 pin ports. Serial ports, by contrast, have only 9 pins. Both type of ports have two rows of pins.
true.
Serial and parallel.
Generally, no; modern computers have several USB (Universal Serial Bus) ports rather than the RS-232 serial ports, Centronics parallel (printer) ports, joystick/game ports or PS2 ports of older machines. In addition, newer machines may have FireWire ports or eSATA ports. The newest computers will usually have USB3 ports rather than the older USB2; USB3 is several times faster than USB2.
if the Dell computer has USB ports, then all you would need is the USB-iPod cable and download/install iTunes. If you system is really old and only have serial ports (9-pin male ports) and no USB ports, then you would need to get a PCI USB card installed into your system. Do not use Serial-USB adapters, as they do not always work.
yes.. but printer and PC should have these ports..
ports of a computer and its functions
Peripheral ports such as COM, USB and serial ports, are input/output interfaces that allow devices to connect to a computer. Expansion slots are sockets on the motherboard where an expansion card is inserted.
Most modern laptops lack any sort of "legacy" ports such as serial ports, let alone them having two. Some older laptops did have multiple serial ports, but there's little point in recommending one because there's no guarantee you could find one. There are options for adding serial ports to a laptop, such as a USB to serial adapter, or a PC card with additional serial ports.
The ports used to connect external sound equipment are Line In, Mic and Line Out. These ports are usually located on the computer's sound card.
A device which connects to the computer is called a "peripheral."
