Computer Memory
The computer memory is a physical device used to store data or programs for use in a computer. Some types of computer memory include RAM (random access memory), ROM (read-only memory), and page cache.

What is a dual inline memory module?
A duel inline memory module (DIMM) is an advanced version of randome access memory (RAM) that came after the singe inline memory module (SIMM) that runs on 168, 184, or 240 pins.
What has more memory a laptop or a desktop?
It depends on what the manufacturer put in and if any was added by the buyer. The technical term for memory is RAM (Random Access Memory) You'll have to check the specs to see which computer has more. Popular stock RAM sizes are 512MB and 1GB of RAM. In general, desktops have the capacity to hold more RAM than laptops. Some laptops now hold up to 4GB of RAM, but you'll likely have to buy extra RAM to max it out. Some desktops now how up to 16GB of RAM. Ram is particularly important in Video and Sound editing. If you're simply needing to run Microsoft Office and surf the web, then a laptop with 1GB of RAM is probably all you'll need.
The role of RAM or random access memory in computer data processing is to hold calculations and information. Once the system is restarted or power is lost, the information within the RAM is lost.
If there was some magical infinitely fast infinite memory computer then a brute force algorithm would have the same running time as an elegant algorithm, so in that case it wouldn't make any difference. However, there is no such thing as an infinitely fast computer or free memory, in the real world you have to make trade-offs and know how those affect your memory-usage and running-time.
Also, unless you know algorithms you are going to have a VERY hard time trying to code any sort of advanced functionality, especially things like encryption which depend on strong randomness, and where a small mistake anywhere in your algorithm can mean that your encryption can be easily compromised by someone who knows what they are doing.
What can you take to improve your memory?
It has been proven that almost every type of berry can help you remember things longer, I suppose you are asking this so that you can do better on tests and what not, so from my research, I have gathered that the CRANBERRY is the best food that will answer your question.
Yes, there is such as thing as too much, because the only time its a waste if the new or old ram that you have or will have has a different clock speed. so one is running faster than the other. the comp processor speed is determine by how fast the slowest ram is moving.
Differentiate between volatile memory and non-volatile?
Non-volatile memory, nonvolatile memory, NVM or non-volatile storage, is computer memory that can retain the stored information even when not powered. Examples of non-volatile memory include read-only memory, flash memory, most types of magnetic computer storage devices (e.g. hard disks, floppy disk drives, and magnetic tape), optical disc drives, and early computer storage methods such as paper tape and punch cards.
Non-volatile memory is typically used for the task of secondary storage, or long-term persistent storage. The most widely used form of primary storage today is a volatile form of random access memory (RAM), meaning that when the computer is shut down, anything contained in RAM is lost. Unfortunately, most forms of non-volatile memory have limitations that make them unsuitable for use as primary storage. Typically, non-volatile memory either costs more or performs worse than volatile random access memory.
'''Volatile memory''', also known as '''volatile storage or primary storage device''', is [[computer memory]] that requires power to maintain the stored information, unlike [[non-volatile memory]] which does not require a maintained power supply.
Most forms of modern [[random access memory]] are volatile storage, including [[dynamic random access memory]] and [[static random access memory]]. [[Content addressable memory]] and [[dual-ported RAM]] are usually implemented using volatile storage. Early volatile storage technologies include [[delay line memory]] and [[Williams tube]].

How much does a 1GB of RAM cost in India?
Improved(and correct) answer:
RAM price depends on what kind of RAM you want, and what company makes it, and who you buy it from. That said, there really isn't much difference in the maker.
You can find the list of prices here: http://www.priceindia.in/computer/ddr-ram-price-list/
Go through it, find something that works for you.
RAM is probably more important than processor speed now. We've reached a point where all processors are fast. So now, the more RAM you have, the faster your computer works.
You could have a poor, or an integrated GPU, and still have fast performance on games and intensive programs just by having enough RAM.
hi,,,,the price of 512 mb is 2100rs you will want to purchase 2 for 1 gb;;;;;;there is not of 1 gb:: i have 1 gb ram::::not so much different:::::::i sugest you to purchase nvidia geforce 256mb:::::to play game::::::ram is not so important for tadays games
Arrange these units in order from smallest to largest kilobyte gigabyte megabyte?
bit byte kilobyte megabyte gigabyte terabyte
Where can you purchase RAM for a Compaq Presario 5BW130 desktop?
The Compaq Presario 5BW130 desktop supports a maximum of 512 MB of RAM using two 256 MB PC100/PC133 SDRAM modules. These modules aren't carried on the sites of most major online retailers, but can easily be purchased on eBay. A reference retailer can be found below.
Note that for guaranteed compatibility, you should purchase "low density" modules. High density modules are cheaper, but aren't compatible with all systems (especially those with Intel chipsets) and tend to be slower.
What is the explanation for the memory organization of 8086?
Two types of memory organization are used:
Linear addressing where the entire memory is available to the processor at all the times ( Motorola 68000 family).
Segmented addressing where the memory space is divided into several segments and the processor is limited to access program instructions and data in specific segments.
The return address.
When a computer is turned off what happens to the data on a Hard Drive?
The entire point of a hard disk is that nothing happens to your data when it's turned off. Data is stored by magnetizing tiny areas of the surface of the disk. They don't need electricity to stay magnetized.
1000000 bytes equals 1 megabyte yet 1024 megabytes equals 1 gigabyte?
There are two definitions. The official definition says: * 1,000 × 1,000 bytes (B) = 1,000,000 B = 1 megabyte (MB) * 1,000 (MB) = 1 gigabyte (GB). This is the definition used for hard drives, DVDs, networking, and everything else. There is also another definition based on 1024 instead of 1000, so 1,024 "megabytes" are equal to 1 "gigabyte". These are used for memory. These are more correctly referred to with MiB and GiB instead of MB and GB: * 1,024 × 1,024 B = 1,048,576 B = 1 MiB * 1,024 MiB = 1 GiB
What is the purpose of memory in a computer?
Hard-drives store large amounts of data for extended periods of time. RAM stores smaller amounts of memory only while it is needed. Data stored in RAM can be accessed much faster than data stored in hard-drives. This is necessary because the processor can only interact with a few numbers at a time. An example might be when running a game - all the most necessary game data is loaded from the hard-drive into RAM. Then, as the game runs, the processor rapidly pulls small bits of data from RAM, performs calculations, and then quickly passes it back. The results are then displayed (through the video card) on the screen.
What cache memory is designed inside the CPU?
L1 and L2; Many years ago L1 was the only cache memory integrated into the CPU (processor) and L2 had to be added to the motherboard. Currently (as of year 2013), CPUs implement both L1 and L2 cache in the casing of the processor. Thus, processors (CPUs) ship with amounts of L2 cache independent for each processor core.
