Temporary storage is usually referring to RAM -- Random Access Memory. Data stored in RAM only exists while the computer has power (nothing is saved).

The main thing that will determine if your computer is slow or fast is the hardware that it has. The faster the hardware the faster your overall computer speed will be (generally). The main that slows down your computer is the the operating system. If you have used Windows XP in the past and made the move over to Windows Vista you would have noticed a dramatic decrease in computer performance. The reason for this is because Vista is actually slower than XP. The main reason for this is because Vista has a lot of fancy things on in that are designed to make it look pretty which are of no use to you when it comes time to actually use the computer.

So the two main things that you have to consider are your computers hardware specifications and the operating system that you are running. I actually specialize in making computer faster whether they be running Windows XP or Vista and if you are interested in learning more, just click on my username to go to my bio page. I'm sure you will find something that will interest you.

Most RAM have the specifications right on the RAM chips. If you have never opened your they are located in between the CPU and the CD/DVD usually. If you can't open your case for warranty reasons, you will have to contact the seller or manufacturer of the computer where you bought it.

If your computer is slow, then it may be because of several things: less RAM, low disk space, poor processor, fragmented hard disk, too many programs installed, etc. If your computer has less RAM, you can change the primary RAM, or buy additional RAM. If your processor is poor, there isn't much you can do, just buy a new one. If you have low disk space, you can delete unwanted files, or move to any other drive than C: If your hard disk is fragmented, you can defragment all the drives, which can (and most probably will) take an hour or more. If you have too many programs installed in your computer, then you can uninstall unwanted programs. Thank You for your stay at Wiki.answers

The number of lines on a bus that can hold data, for example, 8, 16, 32, and 64 lines, which can accommodate 8, 16, 32, and 64 bits at a time.

1 kilobyte = 1024^1 = 1,024 bytes
1 megabyte = 1024^2 = 1,048,576 bytes
1 gigabyte = 1024^3 = 1,073,741,824 bytes
1 terabyte = 1024^4 = 1,099,511,627,776 bytes
1 petabyte = 1024^5 = 1,125,899,906,842,624 bytes
1 exabyte = 1024^6 = 1,152,921,504,606,846,976 bytes
1 zettabyte = 1024^7 = 1,180,591,620,717,411,303,424 bytes

So there are 1024^7 / 1024^3 gigabytes in a zettabyte.
1024^7 / 1024^3 = 1024^4 = 1,099,511,627,776 gigabytes in a zettabyte..!

If you are using the purist SI units meaning of "giga-" and "zetta-" then this would be:
1000^7 / 1000^3 = 1000^4 = 1,000,000,000,000

The simple answer is, it depends.

If the computer is set up to have dual-channel memory, and requires two sticks in a channel, then if you have two 2GB sticks, all your memory will be in the one channel. If you have, instead, four 1GB sticks spread across two channels, you will get twice the memory speed, as the two channels can be set up to read and write independently. It is like having two straws to your milkshake.

Even if you have only one channel, you can still get greater speed by having four sticks instead of two. Some memory controllers will do what is called a "four-way interleave", where they read from each stick in turn, thus getting four times as much data as they would from a single stick; it takes time for memory to get ready, and an interleaved memory access system can schedule the sticks so as to read them in a round-robin fashion, reading four times the data in the same time. However, this is uncommon except in high-end hardware.

If neither of those cases holds true, though, there is no performance advantage. And in fact, in most cases the actual performance advantage for the end user is imperceptible.

Against this, one must weigh the fact that most motherboards only have four memory slots, so if you want to upgrade past 4MB, and you have four 1MB DIMMs installed, you will have to throw them all out before you can upgrade.

Yes, it will just run at the max speed that the motherboard supports. So if the motherboard specifies pc5300, you're going to be running the pc6400 memory which is faster than the 5300 at a lower speed. But it will work just as well as the pc5300. [thumbsuck] Might even run a bit cooler at the slower clockspeed due to higher quality etching for the pc6400 and or larger chip die sizes. [/thumbsuck]

The most basic type of measurement in computers or memory storage systems, are bytes. Bytes are so small however, that usually the smallest unit of memory used in the modern computer systems are kilobytes. Kilobytes are equivalent to 1,000 bytes. Here is a chart to display the most used units in computers, and what they are equal to.

Bytes = Basic Unit

Kilobyte = 1,000 bytes

Megabyte = 1,000 kilobytes

Gigabyte = 1,000 megabytes

Terabyte = 1,000 gigabytes

Currently, modern computers have a max amount of storage of about 1 terabyte, and that is for a $1,000 plus computer. My computer has a total of 500 gigabytes of memory, or 1/2 1 terabyte. My computer cost $750.

Since cache memory logs and saves everything it can be un-secure. And it can be slow.

Cache memory

The advantages of read only memory are its permanence and security. However, the only disadvantage is that a system will require more time as twice in reading the data stored in ROM than in RAM.

RAM is just memory your computer uses to run tasks while its on.

Random Access Memory (RAM) is volatile and based on modules. In comparison virtual memory is allocable to a computer's hard disc. Virtual Memory however, does not have the access speed that RAM affords.

This question should be more specific so that someone can more easily and accurately assist you. However, i will attempt to answer your question assuming that your are asking about the L1, L2, and L3 cache memory types.

L1, L2 and L3 (or level 1, level 2 and level 3) are different memories seperate from the processor, but it is the memory more easiest and quickly accessible by the processor, or cpu. These memories are used by the processor to store common instructions, images..etc. so that it can easly and quickly access it whenever required to. First the processor checks the L1 cache memory (usually the level with the lowest amount of memory), if it doesn't find what it needs there then it searches through the L2 and then L3.

If what the processor needs isn't in the cache memory, then it will check the HDD and RAM.

The number of address lines needed to access N-KB is given by log2N Then the number of address lines needed to access 256KB of main memory will be log2256000=18 address lines.

It is not. They both have features that are good: A computer can complete mathmatics and calculations way faster than the brain A computer can not think or act on instinct By using a combination of both of these forces we can make the world better.

200 pin DDR2 SODIMM is likely going to be between 200-800mhz in speed.

This type of laptop is a Compaq Presario series. The series comes stock with 512 mb of RAM.

The memory bank has two slots for memory modules. The factory memory module takes up one slot and is removable for upgrading.

This series of laptops can hold a maximum of 2 Gigabytes of RAM.

These laptops use SODIMM laptop memory chips, and it does support dual channel functionality.

Most memory manufacturers have these models listed as supporting pc4200 RAM modules; however it is very likely that pc5300 modules also work without issues in these models - many RAM manufacturers now sell this speed of RAM for these machines, and claim it has been tested as compatible.

I suggest contacting either Compaq/HP, or the memory manufacturer to verify which speed (pc4200/pc5300) you need before the install if at all possible. In most cases, this shouldn't be an issue so long as both the modules you install are the same speed; but check first indeedy!

The cheapest, and most effective way to upgrade the memory in these laptops is to purchase (2x) 1 Gigabyte memory modules. Remove the 512 mb module which comes with the machine, and replace the new modules into both slots to acheive the maximum allowance of 2 Gigabytes usable RAM.

Keep in mind that the Operating System may not register the full 2 Gigabytes of RAM when you view the system specifications; however it will use as much of the 2 Gigabytes of RAM as possible during normal operation. This is common with newer OS/RAM combinations and should not be seen as a malfuction.

By "memory stick", I assume you mean flashdrive. If you want to transport pictures from your computer to your flashdrive, stick your flashdrive into the computer, and open up your pictures. When your flashdrive is in place, another small window should open up with a list of options for you. Among these options should be "open files" or something like that. Click on it, and it will open up any files on the flashdrive (If there is nothing on the flashdrive, there will be words at the top, saying "no files on flashdrive" or "flashdrive is empty" or something like that). Go to your pictures file, and drag any pictures you want from the file to the flashdrive. The End.
