A computer is a device or machine for making calculations or controlling operations that are expressible in numerical or logical terms. Computers are made from components that perform simple well-defined functions. The complex interactions of these components endow computers with the ability to process information. If correctly configured (usually by programming) a computer can be made to represent some aspect of a problem or part of a system. ...

Random-access memory (usually known by its acronym, RAM) refers to data storage formats and equipment that allow the stored data to be accessed in any order — that is, at random, not just in sequence. In contrast, other types of memory devices (such as magnetic tapes, disks, and drums) can access data on the storage medium only in a predetermined order due to constraints in their mechanical design.\n\nGenerally, RAM in a computer is considered main memory (or primary storage): the working area used for displaying and manipulating data. This type of RAM is usually in the form of integrated circuits (IC). These are commonly called memory sticks or RAM sticks because they are manufactured as small circuit boards with plastic packaging and are about the size of a few sticks of gum. Most personal computers have slots for adding and replacing memory chips.\n\nRAM is typically erased when a computer is shut down, though some RAM chips maintain data indefinitely without electrical power. Technically, RAM devices are not limited to memory chips, and random-access memory as a storage format is not limited to use as working memory. In a broad sense, modern storage devices for long-term or secondary storage, including magnetic media and laser-readable CDs and DVDs, are forms of random-access memory.\n\nLook up RAM, random access memory in Wiktionary, the free dictionary.Most RAM can be both written to and read from, so "RAM" is often used interchangeably with "read-write memory." In this sense, RAM is the opposite of read-only memory (ROM). Strictly speaking, however, "RAM" and "ROM" are not mutually exclusive designations because "RAM" refers only to the method of accessing stored data, not whether data can be written.

Your computer has a type of memory called RAM (random access memory). It is temporary memory that is used when running programs and doing other tasks. The more RAM you have in your computer the faster it will run b/c it has more "working space"\n\nRAM is sold as a stick-like thingy that looks like this:\nhttp://computer.howstuffworks.com/ram.htm \n\nIt comes in different sizes and speeds and configurations.\n\nthat is a memory stick.\n\nhope that helps :)

ROM (Read Only Memory) is, by definition, a chip programmed with specific information and therefore is not stored on a hard drive. For full information about ROM see the first source below.\n\nA hard drive is a storage device onto which we store data. The second source gives a good overview as to how they work.

Hai buddy\n\nRandom Access Memory which is widely known as RAM is memory cells which can be accessed for information transfer from any desired random location ,thus the name RAM.In simple words it is the storage unit to store your temporary information,you can store the data and retrieve too\n\nwhile\n\nRead Only Memory or ROM is a memory unit that performs the read operation only,it does not have a write capability and you cant modify any of the information stored in ROM

Flash memory is meant to be small and compact, such as flash drives and flash mp3 players. They're nice to have, but they dont have very good capacity (memorywise). Hard drive items are usually a bit more bulky, but have a lot more digital space. Hard drive memory simply means that data is saved onto a hard drive, and spins to access the data. I have no fricking clue what flash memory uses to work.

Okay, home computers come up to 1 terabyte of storage if you would like, are capable of having 2gb of RAM, two video cards with 1gb of ram each, the possibilites are endless, and your question is too vague.  But you're probly still looking for the "any" key, aren't you?

if you're talking about hard drive memory:\n\nclick on "My Computer" (either in start menu or on desktop), RIGHT click on your hard drive, usually labeled as C: unless you have multiple drives...in the pop up window, select "properties" and it should pop right up

A megabyte is 1024 kilobytes. RAM is random access memory. Everything you do on your computer goes through RAM. 256MB is the bare minimum for most modern operating systems. You can buy 128MB modules, but for a few bucks more you can gat 256MB modules. Price is dependent on the system. Is it a PC or Mac? Laptop or desktop? What brand? Do you have any open memory slots? What type/speed of memory? If you go to my link, you can do a memory search.

A bit is the smallest amount of memory you can get on a computer - a 0 or a 1.\n\nA byte is a chunk of these, usually 8 bits. This means you have 2^8, or 256 possible values. This is roughly what you need to store a single character (a letter, a digit or a punctuation mark).\n\nA kilobyte is 1024 bytes. Small files such as pictures or simple text documents are usually measured in kilobytes.\n\nA megabyte is 1024 kilobytes. Larger files, like movies and songs are usually measured in megabytes.\n\nA gigabyte is 1024 megabytes. Hard drives are usually measured in gigabytes.\n\nThere are larger data unit sizes, like terabytes, but they aren't used very much in home computers yet.

In a home computer, storage will usually take the form of random access memory to store the computer programs that are currently running and the documents that are being worked on, a hard disk to store the programs that are not running and the documents that are not worked on at the moment, and a removable media to store purchased programs and archived documents.

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"...

Hardware is the physical componentry of a computer system.  Memory chips, mice, monitors, and keyboards are all hardware.  \n\nSoftware is the information stored on the computer, so programs and data are considered to be software.  Basically, if you can email it to someone, it's software.
