Cache vs bufferboth cache and buffer are temporary storage areas  but they differ in many ways. The buffer is mainly  Found in ram and acts as an area where the cpu can  store data temporarily, for example, data meant for other  Output devices mainly when the computer and the other devices  have different speeds. This way the computer can perform  other tasks. cache, on the other hand, is a high-speed  storage area that can be part of the main memory or  Some other separate storage area like a hard disk. these two  methods of caching are referred to as memory caching and disk caching  respectively.

Cache vs Buffering

Key difference:a Cache transparently stores data so, requests for, that data can be served faster. There is both main types of caches, memory caching and disk caching. A buffer, the other hand, temporarily stores data and the data is the process of the moving from one place to another.i.e . The input device to the output device.

The key difference: caching, which is transparently stored data, can serve faster when requested in the future. There are two main types of caches: Memory cache and Disk cache. buffering, the data that is temporarily stored can be moved from one place to another by the handler. From an input device to an output device.

The

Both refer to temporary storage areas, but they are different in many places. "Buffering" Main use scenario: when other output peripherals have different speeds, the CPU can temporarily store the data to memory staging, at which point the computer can perform other tasks first. "Cache", on the other hand, is a high-speed storage area, which can be either memory or hard disk. Both methods refer to the memory cache and the disk cache in each case.

to ensure the high speed, cache is made of static ram  rather than dynamic ram used for the other part of the  Memory since this is slower. this area is used to store  information that is accessed by almost all the programs  When they are running, and this makes it faster rather than  searching for this information from the disk each time a  program is running as this would be much slower. The  Buffer is made up of ordinary ram running in the computer,  and it keeps track of changes happening in a running  Program by temporarily storing them before the changes are finally saved in  the disk, for example, with word processors where the task  Being written is first stored in the buffer, and the word  processor later updates the file in the disk with the  Contents of the buffer.

To ensure high speed, "cache" is made up of static memory rather than dynamic memory, because dynamic memory is slightly slower. This area is accessed by all running programs, so it's quicker to find content without having to use a slower search disk each time. "Buffering" is usually made up of memory, which keeps track of the latest temporary data of the program until it is saved to disk. example, the word processing software saves the memory in the buffer first, and then saves the cached data to the hard disk.

The buffer is mostly used for input/output processes, for example ,  in printing. when one sends the documents to be printed  to the printer, the information is stored in a buffer,  and the printer can then access this information at its  own pace, and this frees the CPU to perform other  tasks. a buffer is also used when burning information to  Compact disks where the data to be burned is first stored  in the buffer from where it is then transferred to the  disk during the burning process. Cache is mostly used  During reading and wriTing processes to the main disk to make the process faster  by making similar data used by different programs easily  Accessible.

"Buffering" is generally used for output/output processing, for example, the print service, when sending a file to the printer, the document exists in the buffer, the printer can access the area, so that the CPU can perform other tasks first. Buffer is also used in the process of engraving disc, so the data to be burned in the buffer, before the recording to the CD-ROM write. "Cache" Most users can easily access the same data stored on disk when the read/write process operates on the disk.

Cache can either be part of ram or the disk. when the  main disk is used as a cache, the process is referred  to as disk caching, and this also works as memory  Caching where the recently used data is stored in the disk  cache. If a running program wants to access data from  the disk, it first checks the disk cache and will only  Check the disk if the required data is not available in  the disk cache. this makes the data access process much  faster since accessing it from the disk is much slower.  a buffer can&nbsP;only be part of ram. 

The

Cache can be either partial memory or partial disk. This is the disk cache when the disk is used as a cache, which is the memory cache when the data most recently used for memory is stored in the disk cache. When a program wants to access data from a disk, it checks the disk cache first, and if the disk cache is not valid, the program checks the disk (note that there is no cached word), which is much faster than getting directly from the disk. "Buffering" can only be part of memory.

Summary:1.cache is a high-speed storage area and a buffer is a normal storage area in RAM for temporary Storage.2.cache is made from static RAM which are faster than the slower dynamic RAM used for a buffer.3.the buffer are mostly used for Inpu T/output processes while the cache was used during reading and writing processes from the Disk.4.cache can also bes a sectio N of the disk while a buffer are only a sections of the ram.5.a buffer can be used in keyboards to edit typing mistakes whil E the cache cannot.

Summarize:

1. The cache is a high-speed storage area, while Buffering is a part of memory used to store temporary data;

2. Caching uses static memory faster than buffering with dynamic memory (note: should both use memory);

3. Buffering is generally used in input/output processing, while the cache is read/write on disk;

4. The cache can be partially present on the hard disk, while the buffer only exists in memory;

5. The buffer can be used for keyboard input editing, and the cache cannot (note: This also counts:)? )
