What is the use of external storage devices?
External devices are used for storage just like internal devices but with the added bonus of being portable and not requiring space inside your computer. This usually comes at the sacrifice of access time or write times. Depends on the interface used for the external device.
Why Stable storage cannot be implemented?
Since all storage devices are hardware and are therefore vulnerable to the unpredictability of mechanical or electronic device failures. The closest approximation to stable storage are database systems that write data to multiple storage devices at the same time. If one device crashes, the data is still available from another device.
What is a worm storage device?
Worm storage stands for "Write Once, Read Many." This is media that allows one time writes, but can never be altered from that point forward. WORM storage is typically used when compliance with a regulatory agency is required.

It allows up to 14 minutes of recording time.
How does the access time of storage compare with the access time of memory?
access times from memory is 200,000 times faster than access times from storage devices due to the mechanical movement involved.
What was the shipment value for computer storage devices and equipment in 2001?
Shipment values for computer storage devices and equipment, which totaled $9.0 billion in 2000, fell to $8.2 billion in 2001. At that time, some 66 companies competed in the domestic market.
Is access time of memory is slow compared with the access time of storage?
access times from memory is 200,000 times faster than access times from storage devices due to the mechanical movement involved.
What is the name of a memory area used to temporarily hold data from lower speed storage devices to provide better access time?
Cache.
What is a real-time Internet communications service that allows wireless mobile devices to exchange messages with one or more mobile devices or online users?
Wireless instant messaging.

What is the difference between an internal an external storage device?
Deciding what to get for your data storage device need can be a very difficult and daunting task, especially since your two options - internal and external storage devices each has its own pros and cons. Here are some basic points that you may want to consider when buying a storage device.Internal storage devices reside inside your PC. Once installed, they become an integral part of your machine, and due to the complex process of installing, you would definitely hesitate before removing them again. Hence if something goes wrong with an internal storage device, more often than not, you need to take it out of your PC system to have it fixed or to have it replaced. For data back-up, an internal storage device is not a good option since you're most probably backing up files coming from your own PC. Having it connected to your PC most of the time would render it vulnerable to virus and other malicious attacks coming from online predators.On the other hand, an external storage device gives you exactly the opposite of that limitation of internal storage devices. You can bring this kind of storage device anywhere, and the only time it stays connected to your main machine is when you are using it. And since it is portable and can universally connect to all PCs which support it. External storage devices are a great accessory for bringing large files to where ever you want to bring them.In terms of speed, internal storage devices though beat external devices. Since external storage devices rely on another technology/facility to connect it to your computer, transfer speed is severely affected. Internal storage devices download and upload files to your PC faster than the external devices. This is due to the fact that internal storage devices become part of the system once it is installed.On the sharing aspect, external storage devices definitely beat internal storage. You can easily share your files with your friends and contacts by simply connecting the device to their machines. And since most external storage devices now work through USB port connectivity, you are pretty much assured that you can easily transfer your files to your friends'/contacts' PCs in a snap.By-R.Amalakanthan (AK)
