Various devices used to make use of serial ports (Printers, modems, serial mice, joysticks, gps receivers, and much more). The parallel port was designed as a standard for printers, but eventually made use of peripherals such as (zip drives, scanners, hard disk, cd-rom drives and modems)... Now a days you don't see serial or parallel being used too often anymore, since most have made the shift to USB.
Here is some more in-depth information on wiki for the two standards.

What else can I help you with?
How are input devices connected to the computer?
A device which connects to the computer is called a "peripheral."
Are USB ports forcing serial and parallel ports to become legacy technology?
Pretty much, yes. USB ports are smaller and more versatile, and can carry a limited amount of power. Serial and parallel ports are larger and more limited, and cannot be "daisy-chained" like USB devices usually can.
What ports on a laptop are serial ports?
Many modern laptops don't have a serial port at all. The most common serial ports on desktop computers were the old style of mouse ports that look like this picture: http://i32.tinypic.com/29vtir.jpg
What is the difference between a serial port and a parallel port?
Parallel ports are easy to program and faster compared to the serial ports. But main disadvantage is it needs more number of transmission lines. Because of this reason parallel ports are not used in long distance communications. Let us know the basic difference between working of parallel port and serial port. In serial ports, there will be two data lines: One transmission and one receive line. To send a data in serial port, it has to be sent one bit after another with some extra bits like start bit, stop bit and parity bit to detect errors. But in parallel port, all the 8 bits of a byte will be sent to the port at a time and a indication will be sent in another line. There will be some data lines, some control and some handshaking lines in parallel port. If three bytes of data 01000101 10011100 10110011 is to be sent to the port, parallel port communication is faster then serial port.
What are series and parallel ports?
series is newer in ata like series ata and ata the old one is parallel ata
What are the advantages and disadvantages of a serial port?
Having a serial port allows you to plug more stuff in you computer. i think The serial technology and the parallel technology are now old technology because of hardware like USB and Firewire. They are ports on the back of your computer. Serial ports transfers bits one at a time in a single file one bit at a time. Parallel ports transfers data 8 bits are a time across 8 wires. There are still serial ports on your computer, a serial port comes in 9 and 15 pins and is a male. Things that used to and sometimes still do connect to them are mice, external modems, PDAs and cameras. Parallel ports have 25 pins and is female. Most the time printers used to connect to parallel ports.The serial technology and the parallel technology are now old technology because of hardware like USB and Firewire.

What device can be used to upload software to a notebook with a CD drive?
A CD :) I know that is not the answer you are looking for. When looking at the notebook does it have ANY ports? Does it have a USB port? Does it have RJ 11, RJ 45 or serial ports? (If you do not know what these look like just type the port names i have listed in your Google browser and search the images category... You will see pictures of what the ports look like). Once you know what ports you have you can figure out what device you can use to up load data. You just buy an external harddrive/memory unit that has the same connection/connector. If you only have an AC port and a CD drive your options are... A CD.
What is the difference between Ports and Slots?
A port is an I/O connector/device that allows you to interface with something outside of the computer. The most common ports are COM (Communication), Printer, USB (Universal Serial Bus), Video, Mouse, Keyboard, and Ethernet ports. A slot is where you plug in a controller. Often, the controller provides one or more ports that you can use.
What device does the USB support?
USB can be used for literally hundreds of different devices. These include but are not limited to keyboards, mouses, printers, external hard drives thumb drives & cdroms, network interface cards, game pads and joysticks, document scanners, fingerprint scanners, cameras, modems, soundcards, tv and radio tuners, graphics tablets. There are also USB devices which emulate older obsolete ports like serial and parallel ports so that legacy peripherals can be used with modern computers.
What is parallel serial port?
It's kinda like a perpendicular serial port, but instead of intersecting it just kinda lines up.
What do you need to test Com ports?
To test COM ports, you need a computer with a functioning serial port or a USB-to-serial adapter, appropriate software for communication (like terminal emulation software), and a loopback connector or a serial device to connect to the port. Additionally, you may require a null modem cable if you are testing communication between two devices. Ensure that the correct COM port settings (baud rate, data bits, parity, stop bits, and flow control) are configured in the software.
USB ports are fast replacing traditional and ports because of their ability to transfer data quickly?
The Universal Serial Bus (USB) send the signal serially. This would be slower than handling the data in parallel. Modern advances in processing speed has made the USB as fast as older parallel ports. The main advantage of USB is ease of use and 'plugability'. You can attach peripheral devices without switching the computer off first. They are 'Hot Swapable'. There are only four contact pins on a USB socket. Two power and two data lines. This makes it simple, cheap and safe.
