| 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 and how to know if the buffers are working properly. I think there is some problem with buffer function in our storage equipment. I thought that hard drives are storage equipment in computers. Where is data usually stored while in a buffer? How many bits are there in one byte? |

| 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 ten years. The whole idea was to insert a buffering memory in hard drives. That memory was hundred times faster then hard drive speed. When you write something to buffer it is actually wrote in memory. 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. 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. I almost forgot to answer to your additional question. There are eight bits in one byte. |
