Where does memory come from?
409843
Not sure exactly what kind of answer you're looking for, but anatomically, memory is formed by strengthening certain pathways in the brain. First, events enter short-term memory; if they are repeated, either in the environment or through study (revising for exams, say), they get converted into long-term memory.\n\nThe temporal lobes and limbic system (hippocampus and amygdala) are very important in this process. Damage to the medial temporal lobe will cause impaired short- and long-term memory; this is seen in disease states like stroke or damage from temporal lobe seizures, as well as following temporal lobe removal for brain tumors. Damage to both hippocampi (there is one on each side of the brain) produces a rare but devastating condition where the person is unable to form any new memories from that point on, although they can remember everything that happened up to that point.\n\nActivating connections in the brain - cells, synapses - causes biochemical and electrical changes that take a little while to fade away. If the stimulus is repeated, the changes accumulate, and probably trigger the conversion to long-term memory. The exact biological basis (substrate) for long-term memory isn't clear but may involve making new proteins or bits of RNA.\n\nIf you want more detail on the biology, a good phrase to search is "long-term potentiation".

100 trillion bits of information is what the human brain can store. it can alway be exceeded though as the brain then utilises the same zones and creates files just like winzip does which are common.

You really need memory to actually have a computer because all the graphics even at yahoo use a lot of memory. The memory actually just basically lets your computer know about graphics and u know what just ask yourself what does memory do for you?  I bet you will find the answer to that question fast. Your brain memory lets you remember stuff and that could be important. In computers it basically does the same thing it remembers things and also lets you access things. If you didnt have memory in your computer than you could not open folders like my documents because the computer wouldnt remember what that was. There are a lot of technichions that can tell you a lot about memory and that there is also virtual memory and they could go on and on but to make a long answer short just ask yourself "what does my memory do for me" you should get your answer

Ummm, A COMPLETELY empty memory?!... Well, there's no completely memory I think! Memory we allocate, is always full of garbage. BUT, if u use assembly, u can 1st give the value of 0 to the bits of that part of memory u wanna allocate, and then try to do what u want!...

Females:\n\nA memory is something that is engraved in the mind of a person that they can recall over a period of time. The more an image appears the longer a person’s memory of it will last. Remembering things from the past also allows one to learn and remember new things. A few things that may cause the loss of memory are injury, disease, or old age.\nMemories are created by many patterns of neuronal connections. An experiment was performed on rats in a lab. The female rats had weaker memories due to fewer nerve connections. When given hormones however, the female rats memories were sharpened.\n\nWomen have a greater ability to associate names with faces than men. They are also better at recalling lists and details of personal experiences. Because women use more of the right side of their brain, which is used to tag memories with emotions, women’s memories can be triggered by emotions. Overlapping neurons trigger many memories with one sense. For example, the smell of cookies may bring back childhood memories.\n\nMales are more likely to lose their memory at a more rapid rate than women due to the fact that their brains shrink three times faster than the female brain

The same way it is stored on any other magnetic media-- there is a read-write head, a tiny electromagnet that creates tiny magnetized spots on the special coating of the disk surface. It writes by magnetizing the little spots and reads by sensing the magnetism in the spots it wrote on. \n\nThe written areas are ones, the areas not written are zeros. That is binary data. The whole rest of the computer, the hardware and the software, is to sort, compare and combine those patterns of 1's and 0's. Everything on the computer, including the windows, the colors, the text and the pixels of photos, the data and the programs that do things with the data, are stored in binary form on disks, either in your machine or on a server somewhere.

You measure memory in computers with MB and GB because B = bytes = binary coding.  The human brain is not binary, so you cannot do the same with the human brain.\n\nIt's like trying to measure the information content of a street by counting lines, lanes, dots, and signs.  It's meaningless.\n\nI've said it before, but everyone's so enamored with the notion of parallels between human intellect and computers that they all just ignore it.

Computer memory is perhaps the most rapidly changing component in computer systems. Back in the early '80s, 1K memory chips were quite common in the first home microcomputers. Now, 25 years later, the average home computer may contain memory modules of 1GB, representing growth by a factor of 1 million times, compared with only a 1,000-fold growth in CPU speed.\n\n \nDespite this enormous increase in memory capacity, many of the problems that exist on today's machines are the same as those of their early predecessors--namely, running out of memory. The more RAM that is available to a software developer, the more the developer tends to use. Certainly techniques of memory conservation have changed with the times. In the early days of computing, programmers used clever tactics to tighten code loops or reuse blocks of memory at the expense of code readability, in order to cram impressive amounts of code into tiny amounts of RAM. Today, code size is rarely a concern anymore, and attention has shifted to storing large amounts of data--images, video, audio, and tables--but little else has changed. The articles in this series deal with memory management issues on modern Unix-like systems. Most of the topics apply to all computers and operating systems.\nMemory management is an important concept to grasp regardless of which programming language you use. You must be most careful with C, where you control all memory allocation and freeing. Languages such as C++, Java, Perl, and PHP take care of a lot of the housekeeping automatically. Nevertheless, all of these languages and others can allocate memory dynamically.

Main memory is what is called RAM. Always "on" when the computer is on and so access is very fast. Disks must be opened and read and the stuff stored on disks must be brought into main memory and displayed or used, so disk access is slower (not so much that you'd notice).

The scientists that constructed the experiment looked at the amount of space it takes for a computer to store written files and programs. Theoretically, you can assume that certain knowledge or tasks (such as mastering the english language) can be converted to hypothetical "memory" that your brain has to store. Depending on the size or complexity of what it is that is stored, scientists can figure what the average human brain can store by looking at the amount of things an average human can do and also memorize.

cache is memory, just like any other memory on your computer.\nThe difference between RAM ( random access memory) and cache\nmemory, is the location and speed, and how it is used.\n\nIt was discovered that by PREDICTING what memory locations\n" Were GOING to be used ", the computer could speed up the\nthe process of reading the next set of memory locations,\nby having a "predictor" program load the memory into VERY\nfast memory, close to, or inside the CPU ( Central Processing UNIT ie the Pentium chip ). There are different levels of Cache RAM, usually called L1, L2, L3 etc. (Level 1, Level 2etc. ) with\nL1 Cache being built right on the chip itself, or on chips\nbuilt onto the CPU chip module at the factory. L2 Cache ram\nis usually added in slots very close to where the CPU ( Pentium), is located on the motherboard. Believe it or not,\nthe computer chips run so fast, that electricity, moving at the speed of light, takes TIME, to travel across the circuitboard, so that the L1 cache is in the heart of the CPU, and the L2 add on cache is as close as possible to the\ncore to speed up the transfere.\n In early Pentium ( and AMD, Cyrix, IBM, etc. clones,) the\nL1 cache was controlled by what can be considered an entire computer WITHIN the CPU. This "computer" had a program, with\nits own ram, and rom, and it was pre-programmed at the factory. Its job, was to watch what the (big) computer was doing, and predict, what the computer was going to do NEXT. For example, if you were running a program that used program lines 345, 346, 347, 348, then it would predict that you\nwould use lines 349, 350, 351, 352, etc, and load them from the " SLOW" ram cards in the ram slots, into the blazing fast Cache ram, right inside the CPU itself, where the\nCPU could access it immediately. There are different kinds of cache ram within the "Cache" " Predictor" program, such\nas TAG ram, Dirty ram, etc. which are used to keep track of what ram is loaded, used, and changed, by the running software that the CPU is currently using. Tag ram would keep  a list of the ram locations that were loaded into the L1\ncache, and the Dirty ram, would keep track of which L1 cache\nlocations had CHANGES made - when the "predictor" program\ndecided that NEW locations of slow RAM were going to be used, it had to put back the old RAM locations' memory contents. It Could ignore memory values that WERE NOT CHANGED ( saving time otherwise spent writing the information BACK to the slow RAM ), but would have to write\nback any CHANGED ram back to the slow ram (marked dirty).\n AMD invented very clever and powerful "predictor" programs in some of its early chips, and this made such a dramatic difference that it out-performed the much more expensive Pentium chips. The "predictor" computer program component is now extremely important in achiving faster speeds. CPUs typically have 64k ( K is one thousand (( 1024 bits) ), 128 K, 256K, or 512K of cache built in, and many motherboards can have slots near the CPU that the user can add more\nL2 cache ram, for use by the predictor CPU program section.\nCache ram is typically much faster, but much more expensive to construct in the factory, so that chips with more cache are usually a lot more expensive. Since CPU speeds are reaching a limit for the moment, the manufacturers are increasing the L1 CACHE to 1 or more MEGA BYTES, on the high end chips.\n SOOooooo... cache is not "just" fast memory. It is a program, inside the CPU, running constantly to predict what memory is "going" to be used. This program goes out to the slow ram, and grabs the memory contents, and loads it into\nL1 cache BEFORE the computer asks for it, to speed up memory transfere. If the predictor is correct in GUESSING the next memory locations, the entire computer speeds up greatly....\n\nHope this clears up "cache"...

D. memory is internal, assuming you mean the "consumers" memory of past experiences, and not the memory of other people, or their computer's memory.

Physical memory is the capacity of the memory card (RAM) you added to your mother board. ie 64,128, 256 MB etc.\n\nVirtual memory is actually existing in your HD. When more memory need arises a specified amount of memory from hard disc will be used. Its called virtual memory. You can  programically change the amount of disc space that can be used as virtual memory

The CPU does not hold a memory card.  The CPU (central processing unit) is what operates the computer.  It is a separate entity within a computer from the RAM (random access memory) cards and your hard drive, both of which are types of memory.  Consult your owner's manual for where to locate your RAM and hard drive are located, to remove them and upgrade them.
