Memo-posting is a banking practice used in traditional batch processing systems where temporary credit or debit entries are made to an account before the final balance update occurs during end-of-day (EOD) processing. The temporary entry created during memo-posting is reversed once the actual transaction is posted during batch processing.
It is an alternative to the older Memo Posting style. There are several characteristics that distinguish a real-time posting system: Transactions appear to customers and staff as soon as the item is posted and does not need to be re-processed at night to create the hard post .
Hard disk drives use a rotating magnetic disk to store data; access time is longer than for semiconductor memory, but the cost per stored data bit is very low, and they provide random access to any location on the disk. Formerly, removable disk packs were common, allowing storage capacity to be expanded.

For most disks, each sector stores a fixed amount of user-accessible data, traditionally 512 bytes for hard disk drives (HDDs), and 2048 bytes for CD-ROMs, DVD-ROMs and BD-ROMs. [1] Newer HDDs and SSDs use 4096 byte (4 KiB) sectors, which are known as the Advanced Format (AF). The sector is the minimum storage unit of a hard drive. [2]
It is required, however, for the boot partition (i.e., the drive containing the Windows directory) to have a page file on it if the system is configured to write either kernel or full memory dumps after a Blue Screen of Death. Windows uses the paging file as temporary storage for the memory dump.
Blocking is almost universally employed when storing data to 9-track magnetic tape, NAND flash memory, and rotating media such as floppy disks, hard disks, and optical discs. Most file systems are based on a block device , which is a level of abstraction for the hardware responsible for storing and retrieving specified blocks of data, though ...
Portable solid-state drive (SSD) is a common solid-state storage device that uses semiconductor cells on integrated circuit assemblies for mass storage. Compared to hard disk drives and similar electromechanical disk storage that use moving physical parts to spin a platter or disc, SSDs are typically more compact, quieter, more resistant to ...
