what is data storage?
The process of storing data and information in a storage medium is known as data storage.
what is digital storage?
When data is electronically stored on storage medium in digital devices such as desktop computer, laptop, smartphones, etc., it is known as Digital Storage.
what are the two types of digital storage
Digital Storage can be broadly classified into two forms: temporary memory (Primary Storage) and permanent memory (Secondary Storage).
what is a storage medium
Storage medium generally is any hardware that can store data permanently or temporarily.
features of digital storage
In terms of memory hierarchy, the digital storage can be categorized as:
1. Internal Memory: Processor registers and cache.
2. Main Memory: The system Random Access Memory (RAM) and controller cards.
3. On-line Mass Storage: Secondary storage.
4. Off-line Bulk Storage: Tertiary and Off-line storage.
differentiate between online and offline storage
Offline storage implies any storage that is not currently connected to the computer whereas online storage implies that the storage is currently connected to the computer.
what is volatility
Whether the information is stored even after the system is turned off?
what is mutability
Does it allow only reading, writing, or both, or overwriting of stored information?
what is addressability
What type of addressing does it use to access stored information?
what is accessibility
Can it access any information from anywhere in the same amount of time or due to sequential (one after another) storage of information the time to access information is dependent on the last accessed information.
what is capacity
What is the total amount of information that the storage medium can hold?
what is performance
What is the size of largest chunk of data, access time and the rate at which data can be read from or written to the device?
what is security
Does it store encrypted data?
what is energy use
Is it energy efficient?
By default, the data is stored in the largest storage device _________ or _______________
- the hard drive
- secondary storage device (SSD)
full form of NAS
Network Attached Storage (NAS)
what is cloud storage?
Cloud storage is an online storage that requires internet connectivity. It allows unlimited storage. It can be thought of as very large online data storage on the web. If you want to access the file anytime, anywhere you can just login into cloud storage and get the file. It is not needed to carry all your files in flash drives or CDs etc
benefits of cloud storage
- Usability and Accessibility
It allows user to upload, download and organize data in folders. It can be accessed anytime and anywhere with internet connectivity. - Recovery
It can be used as a backup device thus ensuring the availability of files even if they are deleted or corrupted on your local system. - Security
The data on cloud storage is safeguarded against any type of hardware failure and can be accessed only after the identity of the user is assured through login and password. - Cost Saving
It frees the owner from the additional cost of maintaining hardware and software to store data. - easy sharing - It allows sharing of data with other users. It allows to set permissions like read only, read and write etc.
- Data Backup
Cloud storage can perform automatic backups, which is very easy to schedule for one, many or all of the drive data. - Collaboration
It allows multiple people to work on a document at the same time thus allowing collaboration. These multiple users can be at anyplace in the world. They would just need an internet connection.
