Disk partitioning or disk slicing [1] is the creation of one or more regions on secondary storage, so that each region can be managed separately. [2] These regions are called partitions. It is typically the first step of preparing a newly installed disk after a partitioning scheme is chosen for the new disk before any file system is created.
Tertiary storage or tertiary memory [7] is a level below secondary storage. Typically, it involves a robotic mechanism which will mount (insert) and dismount removable mass storage media into a storage device according to the system's demands; such data are often copied to secondary storage before use.
The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
The 1980s saw the minicomputer age plateau as PCs were introduced. Manufacturers such as IBM, DEC and Hewlett-Packard continued to manufacture 14-inch hard drive systems as industry demanded higher storage; one such drive is the 1980 2.52 GB IBM 3380. But it was clear that smaller Winchester storage systems were eclipsing large platter hard drives.
There are four major storage levels. [1] Internal – Processor registers and cache. Main – the system RAM and controller cards. On-line mass storage – Secondary storage. Off-line bulk storage – Tertiary and Off-line storage. This is a general memory hierarchy structuring. Many other structures are useful.
In computer operating systems, memory paging (or swapping on some Unix-like systems) is a memory management scheme by which a computer stores and retrieves data from secondary storage [a] for use in main memory. [1] In this scheme, the operating system retrieves data from secondary storage in same-size blocks called pages.
Most email software and applications have an account settings menu where you'll need to update the IMAP or POP3 settings. When entering your account info, make sure you use your full email address, including @aol.com, and that the SSL encryption is enabled for incoming and outgoing mail.
A backup strategy requires an information repository, "a secondary storage space for data" [7] that aggregates backups of data "sources". The repository could be as simple as a list of all backup media (DVDs, etc.) and the dates produced, or could include a computerized index, catalog, or relational database.
