Each file is using 10 blocks of space. (Here, the block size is unimportant.) The remainder of the disk space is one free block. Thus, additional files can be created and saved after the file E. If the file B is deleted, a second region of ten blocks of free space is created, and the disk becomes fragmented.
Fragmentation (computing) In computer storage, fragmentation is a phenomenon in which storage space, main storage or secondary storage, such as computer memory or a hard drive, is used inefficiently, reducing capacity or performance and often both. The exact consequences of fragmentation depend on the specific system of storage allocation in ...
Limiting the speed of data sent by a data originator (a client computer or a server computer) is much more efficient than limiting the speed in an intermediate network device between client and server because while in the first case usually no network packets are lost, in the second case network packets can be lost / discarded whenever ingoing data speed overcomes the bandwidth limit or the ...
Invented. 1884 (140 years ago) (1884) A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. [1][2] Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel ...
As a hit-driven business, the great majority of the video game industry's software releases have been commercial disappointments.In the early 21st century, industry commentators made these general estimates: 10% of published games generated 90% of revenue; [1] that around 3% of PC games and 15% of console games have global sales of more than 100,000 units per year, with even this level ...
In computing, computer performance is the amount of useful work accomplished by a computer system. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. When it comes to high computer performance, one or more of the following factors might be involved:
Defragmentation. In the maintenance of file systems, defragmentation is a process that reduces the degree of fragmentation. It does this by physically organizing the contents of the mass storage device used to store files into the smallest number of contiguous regions (fragments, extents). It also attempts to create larger regions of free space ...
Benchmark (computing) A graphical demo running as a benchmark of the OGRE engine. In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it.
