Defining Your Hard Disk Preference

by : Jon Caldwell

Cellular or mobile phones, digital cameras, pocket personal computers, mini DV cameras, handheld video game consoles are only a few of the techie devices that use flash memory cards to store data and information.

The Flash Memory card, or memory card (MC) for short, is a non-volatile type of memory device that is used in most gadgets today. These MCs are installed directly to the device (such as mobile phones) however, if you are using it as an alternative to the USB flash drive, you will need a card reader before you can use your MC. There are different types of card readers available on the market. Some only have one slot while some do have 8 slots or more. Other card readers also have different kinds of slots (i.e. card readers that have slots for micro SDs, MCs with adapter etc.).

The good old floppy diskette that has been the universal data saving device years ago is already phased out. Though some stores still sell the floppy disk, these are normally the old stocks and store owners just want to get rid of them. In some computer shops, their computers do not anymore have the floppy drive; rather, you'll see hollow rectangular plugs all over the CPU. What you see are the USB ports. These ports have a lot of uses as you can attach different kinds of additional devices such as external hard drives.

One example of an external hard drive is that of the USB flash drive. This device replaced the floppy disk, and people prefer using it since the drive's capacity can reach up to 8GB (compared to the 1.24MB capacity of the floppy).

The Universal Serial Bus (USB) in the computer is a port that allows, well, devices with USB connectors to be attached or linked to the computer. This port enables the user to attach a wide variety of hard drives to store their data.

In some operating systems, the devices you attached to your computer through the USB are detected automatically (so, less the hassle of looking for the driver and installing it manually). These devices range from USB flash drives, additional external devices such as ROMs, floppy drives (though you'll most likely find only a number of people who still use this) and so on and so forth. You can even transfer files from your mobile phone to your computer's local hard drive through the USB (if your computer or mobile phone is not Bluetooth or infrared capable).

Playing games run from a CD, listening to all kinds of music files in any format, watching movies with a VCD format (CD-ROM is different from a DVD-ROM) and reading data files-these are only a few of the things the CD-ROM can do.

The Compact Disc Read Only Memory can do wonders. Pop your CD inside your ROM and you can do all the things mentioned above. PC games are installed in compact discs so you can play your favorite game on any computer with a CD-ROM. Plus, depending on your CD-ROM's features, you can even buy blank CDs and store your data in it (from music to document files).

According to Wikipedia, a free for all online public encyclopedia, the 3½ floppy diskette that was once the universal storage device of people from all ages and stature, is starting to be removed from the market. It utilizes 512 bytes per sector, has 18 sectors per track and has 80 tracks per side. The total capacity of the said storage device is around 1.4 MB per disk. Now, let us dissect the whole thing.

The diskette contains a disk of lean, elastic magnetic storage film covered with a four sided synthetic case. It can be inserted inside a floppy disk drive, however, the said drive is being pulled out in the marker too since USB flash drives have entered the scene.
