Double buffer. Is caching is same as spooling? 45. Spooling is useful because devices access data at different rates. Caching and spooling are not necessary due to the fast and shared-access natures of the device. Explanation: None. Spooling could be used to stage data to the device when multiple users desire to read from or write to it. Spooling, buffering and caching are terms often used interchangeably to describe this type of resource scheduling, although computer science does differentiate. Buffering matches the speed between the sender and receiver of the data stream. Activity 1F Activity Outcome: Describe the following concepts in relation to operating system: Multitasking, Multiprogramming, time sharing, buffering, spooling, caching. If the VLC buffering is due to the playback of network resources, then increase the value after "Network caching". Cache speeds up processing time because it stores frequently used instructions and data. Just like a cache buffer is also a midpoint that holds data but it don't accelerate the speed of processes like Cache accelerates. Spooling, buffering and caching. For example, the files you automatically request by looking at a Web . Cache can also be a section of the disk while a buffer is only a section of the ram. Caching fastens the access speed of the repeatedly used data. Cache is made from static ram which is faster than the slower dynamic ram used for a buffer. 7:00. A buffer is a segment of memory or storage in which items are placed while waiting to be transferred from an input device or to an output device.
