Memory
...n the beginning of this paragraph? Memory is not just storage of information, but also the ability to retrieve that information. Now someone can understand, how comes that someone like in an example remember things that he ˇ§forgot.ˇ¨ Did that accident erased everything what that person knew? NO! The accident just stopped that personˇ¦s ability to retrieve information. So there is the key why the person, after sometime, will remember everything about what he/she knew before the accident. Memory and how memory works is one complex thing, even if it is a ten or twenty yearˇ¦s old computer, or a small puppy, it is complex. To break that complexity, a scientist broke this thing down into categories. There are three categories of memory, or how scientists like to say, three categories of duration. All of these memories were placed in the persons brain. Sensory Memory „» it is memory that lasts the least (1-2 seconds at most), and picks up everything, but filters some of information and pass some to short term memory. It also retrieves information from the short term memory. Short term memory „» it is memory that last longer than the sensory memory (15-30 seconds). As well as the sensory memory it filters some information. Short time memory sends information to the long time memory and retrieves information from it. Long term memory „» it is memory that last the most, as little as 30 seconds and as long as a person lives, or other way said for decades. The long time memory retrieves information from short term memory, stores it, than sends it to short time memory. (Web-us, How does memory work is the procedure of chemicals is not totally known yet, but what is known is that memory has three steps of process of memory to long term memory and from. Encoding „» is a first step; it is actually the transferring of information into a language of brain. It is similar to transferring what person types to 0s and 1s in computers. Storing „» the information that has been transferred in process of encoding would be saved in the brain, processes known as storing. It is the same as storing document to the hard drive, CD, floppy drive, USB storage devices, on a computer, or into the Ram memory for short time. Open program is in computers ˇ§short timeˇ¨ memory or Ram memory. Retreating „» is the process of ˇ§usingˇ¨ of what is stored or pulling information when person needs it. In computer world it is opening document that person have saved on hard drive, or pulling the program on front of every program that person have opened, by clicking on the task bars icon of that open program (Wikipedia, 2006, Web-Us, 2005) The model of a living thing is copied to many applications. Our muscles are copied and used in diggers, and other equipment. Even as simple thing as the light bulb was copied from the fire bag. Or complex thing like helicopter is copied from some kind of bug as well. Is not that amazing that people copy everything, but give no credit to it. The memory particularly is copied as well in many applications, from computers, cell phones, even cars and home appliances. It was not long ago that we started seeing stoves and ovens with touch panels, which they use the simple memory modules. A person touches the button to raise the temperature, and on electric wave is sent to the chip where is the information is stored what the stove has to do. Then the microchip sends signal to the burner to start up. The sensor which measures temperature sends information to the chip. When the oven reaches the desired temperature,...
