What distinguishes some storage media from others?
Whether they are removable or not
What is a storage device according to the text?
A hardware where data is stored
Where can remote storage devices be located according to the text?

What is the advantage of internal storage devices over external storage devices?
They require no additional desk space and are usually faster
What is the meaning of random access in terms of storage devices?
Data can be retrieved from any location on the storage medium
What is the main difference between random access and sequential access in terms of data retrieval?
Random access allows data to be retrieved from any location, while sequential access allows retrieval of data only in stored order
What is meant by logical representation in terms of storage systems?
Anything stored on a storage medium, such as a program, document, digital image, or song
Which type of storage devices use random access for retrieving data?
CD/DVD drives and USB flash drives
What is the advantage of remote storage devices accessed via the Internet?
They are accessible from any computer with an Internet connection
What is the main characteristic of sequential access in terms of data retrieval?
Retrieval of data can occur only in the order in which it was physically stored on the storage medium
What is an example of something that would be logically represented on a storage medium?
A program
What is an example of a physical representation in terms of file storage?
A document that was just created and then saved
What do nonvolatile storage devices allow?
Storage media are used for anything that needs to be saved for future use
What is the main difference between portable and volatile storage systems?
Portability determines the physical size of the storage system, while volatility determines the data retention characteristics.
What distinguishes internal storage devices from external and remote storage devices?
Internal storage devices are directly connected to the system unit, while external and remote devices are accessed over a network.
What defines a storage system's characteristics in terms of how data is accessed and represented?
The type of storage technology used in the system.
What differentiates removable storage media from non-removable storage media?
Removable media can be physically taken out of the storage device, while non-removable media is permanently fixed in the device.
How does random access differ from sequential access in terms of data retrieval?
Random access allows direct retrieval of data at any point, while sequential access requires scanning through the data from the beginning.
What is the main advantage of remote storage devices located on another computer?
Access to remotely located data even if the local system experiences a hardware failure.
What is the main advantage of internal storage devices over their external counterparts?
They are usually faster and require no additional desk space
What type of access allows data to be retrieved from any location on the storage medium?
Random access
What is meant by the term 'volatility' in the context of storage devices?
The nonvolatile nature of storage devices
Which storage media is an example of something that would typically use random access for retrieving data?
CD/DVD drive
What distinguishes some remote storage devices, such as those accessed via the Internet, from others?

Where can remote storage devices, such as those accessed via the Internet, be easily located according to the text?
From any computer with an internet connection
What is an example of a physical representation in terms of file storage?
A program or document stored on a storage medium
How are storage devices typically identified as described in the text?
By their random or sequential access capability
