| I am a newbie in computer waters, but I manage to handle somehow. Anyway, yesterday I was with some computer wizards from my company, and I heard them talking about buffers as short term storage. I thought that hard drives are storage equipment in computers. For how long is data stored in a buffer? |

| Buffer is short term for buffering memory. It was a technology, which was the main speed improvement of computers, along with CPU's speed, in the last decade. The whole idea was to insert a buffering memory in hard drives. That memory was 100 times faster then hard drive speed. When those memories receive data for writing, computer can handle another task. In the meantime, the data from buffer memory is slowly written to the hard drive. Data is stored in buffer until it was written on hard drive. Therefore, more buffer hard disk had, his speed was faster. However, that technology has one big problem. Buffer memory is RAM type of memory, therefore, it handles data while it has power. In the case of power failure, all the unwritten content from the buffer memory would be returnlessly lost. |
