A bit-by-bit copy of the original storage medium is referred to as a "disk image." This type of copy captures all the data, including files, file system structure, and metadata, precisely as it exists on the original medium. Disk images are often used for backup, data recovery, or to create exact replicas of storage devices for various purposes. Common formats for disk images include ISO, IMG, and DMG.
MT 081 refers to "Mankind," a comic book series published by Marvel Comics, and MT 082 refers to "Magnetic Tape," a storage medium commonly used for data storage and backup.
Auxiliary storage devices are used to provide additional, portable storage, as opposed to hard drives which are fixed inside the computer and serve as primary storage devices. ------------------------------------------------------------------------------------------------------------------ Auxiliary storage is a term used in mainframe computing and refers to the medium on which paging datasets reside.
A storage device stores data onto a storage medium. For example a tape backup device writes data onto tape medium
Backing storage refers to non-volatile storage systems used to retain data permanently, such as hard drives, solid-state drives, and optical discs. It serves as a complement to primary storage (like RAM) by providing a larger capacity for data retention, even when the power is off. A media track, on the other hand, is a concentric circle on a storage medium, such as a hard disk or optical disc, where data is recorded and retrieved. Each track can hold a significant amount of information organized into sectors, which are the smallest units of storage on the medium.
Volatile Storage
768K typically refers to 768 kilobytes, which is a unit of digital information storage. In terms of bytes, 768K equals 768,000 bytes or 768 x 1,024 bytes, which equals 786,432 bytes. In the context of computer memory or storage, it can indicate the size of a file or the capacity of a memory stick or other storage medium.
Optical dense refers to the index of refraction. If one medium is optically denser than another, then its index of refraction is larger, meaning the speed of light in the optically denser medium is smaller.
Common characteristics of storage technology include capacity, speed, durability, and accessibility. Capacity refers to the amount of data that can be stored, while speed indicates how quickly data can be read or written. Durability encompasses the longevity and resilience of the storage medium, and accessibility describes how easily data can be retrieved and shared. Additionally, many storage solutions offer scalability to accommodate growing data needs.
Serial access storage refers to a type of data storage where information is read and written in a sequential manner, meaning that data must be accessed in a specific order. This contrasts with random access storage, where data can be retrieved in any order. Examples of serial access storage include magnetic tapes and some types of optical storage, which are often used for backups and archiving due to their high capacity and cost-effectiveness. However, accessing specific data can be slower since the storage medium must move to the correct position sequentially.
IO intensity refers to the level of input/output operations being performed on a storage device or system. It measures how frequently data is being read from or written to the storage medium, and high IO intensity typically indicates a heavy workload that can impact performance.(IO stands for Input/Output)
Inoculation is the term that refers to the purposeful addition of microorganisms into a laboratory nutrient medium.
Backup storage refers to a storage device, medium or facility that is used for storing copies and instances of backup data. Backup storage enables the maintenance, management, retrieval and restoration of backup data for any individual, application, computer, server or any computing device.
