Data structure alignment is the way data is arranged and accessed in computer memory. It consists of three separate but related issues: data alignment, data structure padding, and packing . The CPU in modern computer hardware performs reads and writes to memory most efficiently when the data is naturally aligned, which generally means that the ...
Block (data storage) In computing (specifically data transmission and data storage ), a block, [1] sometimes called a physical record, is a sequence of bytes or bits, usually containing some whole number of records, having a maximum length; a block size. [2] Data thus structured are said to be blocked.
In the context of data storage, a filesystem block is an abstraction over disk sectors possibly encompassing multiple sectors. In other contexts, it may be a unit of a data stream or a unit of operation for a utility. [12] For example, the Unix program dd allows one to set the block size to be used during execution with the parameter bs=bytes ...
Logical block addressing ( LBA) is a common scheme used for specifying the location of blocks of data stored on computer storage devices, generally secondary storage systems such as hard disk drives. LBA is a particularly simple linear addressing scheme; blocks are located by an integer index, with the first block being LBA 0, the second LBA 1 ...
Liquid-cooled data centers made up only about 1% of the market heading into this year but are now set to take off, perhaps leading to a big upheaval in the fast-growing AI server industry.
The block time is the average time it takes for the network to generate one extra block in the blockchain. By the time of block completion, the included data becomes verifiable. In cryptocurrency, this is practically when the transaction takes place, so a shorter block time means faster transactions.
inode pointer structure. The inode pointer structure is a structure adopted by the inode of a file in the Unix File System (UFS) to list the addresses of a file's data blocks. It is also adopted by many related file systems, including the ext3 file system, popular with Linux users.
A disk pack is a layered grouping of hard disk platters (circular, rigid discs coated with a magnetic data storage surface). A disk pack is the core component of a hard disk drive. In modern hard disks, the disk pack is permanently sealed inside the drive. In many early hard disks, the disk pack was a removable unit, and would be supplied with ...
