Zip is a thicker disk and has 70x (100MB), 174x (250MB), or 521x (750MB) the capacity of a floppy. 100MB (70x) Zips were the original, and 750MB are the latest version.  They offer a pretty economical solution to portable data storage.  USB flash drives are more compact and will work on most machines with USB connectivity if you just need to move data around and not keep it for a while.  If you do need to keep data, I would be inclined to burn CDs instead of using Zip disks as CD burners are cheaper than Zip drives and the CDs can be read on any machine without special Zip drive hardware. Blank CD media is also cheaper than blank Zip media.

USB flash drives are NAND-type flash memory data storage devices integrated with a USB interface. They are typically small, lightweight, removable and rewritable. Memory capacity typically ranges from 128 megabytes up to 64 gigabytes [1], limited only by current flash memory densities, although cost per megabyte increases rapidly at higher capacities due to the expensive components. For example, as of October 2006, flash drives were available in retail stores at US$25 for 512MiB, US$35 for 1GiB, US$60 for 2GiB, US$100 for 4GiB, and US$160 for 8GiB. [citation needed]\n\nUSB flash drives have several advantages over other portable storage devices, particularly the floppy disk. They are more compact, generally faster, hold more data, and are considered more reliable (due to their lack of moving parts) than floppy disks. These types of drives use the USB mass storage standard, supported natively by modern operating systems such as Linux, Mac OS X, and Windows.\n\nA flash drive consists of a small printed circuit board encased in a robust plastic or metal casing, making the drive sturdy enough to be carried about in a pocket, as a keyfob, or on a lanyard. Only the USB connector protrudes from this protection, and is usually covered by a removable cap. Most flash drives use a standard type-A USB connection allowing them to be connected directly to a port on a personal computer.\n\nMost flash drives are active only when powered by a USB computer connection, and require no other external power source or battery power source; they are powered using the limited supply afforded by the USB connection. To access the data stored in a flash drive, the flash drive must be connected to a computer, either by direct connection to the computer's USB port or via a USB hub.

USB External hard drives are very affordable and have the advantage of being portable. Another alternative is copying your data to a DVD(s). Then store them offsite in case of a fire or other disaster.

firewire\n\nIt's quicker then a usb port and it allows you to transfer outside data quicker such as harddrive info from another computer or transfer a vhs tape to a dvd , cd or vice-versa.

In general, COM ports, also known as serial ports, are completely unrelated to USB ports. USB ports are a standard designed to replace all parallel ports, serial ports, and other type of ports with a single "universal" type for peripherals. \n\nSo to answer your question, the answer is "no".

You wont be able to read SMART attributes for a USB device because they don't exist. The SMART technology is built onto a small board on the bottom of Hard Disk Drives - sort of like a mini-motherboard. USB devices aren't really "drives" although they use a similar protocol in order for the OS to acknowledge the device.

Um, yeah.  Generally a computer mike will hook either directly into the sound card in the back of the computer, but these days USB Mike/Headset combinations are becoming more common.  They are useful for games and VOIP.  The USB ones are generally nicer, but require additional software to be installed on the computer.

No difference, they are the same thing just what people call them. A USB Drive or Pen contains flash memory so technically its a flash drive.

A usb device like headphones draw their power from the mother board on the computer if you allready have alot of things hooked up to it then the head phones were just the final item to kill it when you replace it just make sure its strong enough to do all you whant.

Since USB is a flash memory computer can read the data fastly.But when u r copying from computer to USB,Computer fetches data from Hard disk which takes more time than Flash memory.So it takes more time to copy from computer to USB than USB to PC

It should be "plug and play". The name of the drive will depend on which USB port you plug it into (so my computer calls my flash drive by a different letter if I plug it into a different port).\n\nHave you tried restarting your computer? I've had this problem when installing plug and play devices before - the computer appears not to have installed the software, but it has, it only becomes active after you have restarted it.
