Which is faster SRAM or DRAM?

Typically SRAM is faster than DRAM.

Because Static RAM requires anywhere from 4 to 6 transistors and some wiring.The memory never has to be refreshed.

It's therefore faster than dynamic RAM.

Because it has more parts, though it takes up more space on a memory chip, which gives the chip less memory and makes it more expensive.

Factors in upgrade memory?

The easiest way to upgrade your ram will be to find out what motherboard your system has and have that information with you when you go to buy the ram. Give the info to the salesperson and ask what kind and how much ram you will need. You could also remove one simm from your ram slot and take it with you to the store or write down the type and speed and have that with you. I suggest bringing the ramm with you, that way if they cant look up your motherboard stats or you cant find the stats you can at least upgrade the amount of ram if not the type. otherwise You will need to check your motherboard specs to see what type of ram you will need, and how much you can use in it. It will also tell you what slots to put the ram into, for instance some motherboards use sdram and only work as dual memory if its inserted into specific slots. Otherwise it works as standard ram and wont share between them. Also if you are using xp only 3 gigs of ram will be recognized even if you put in 4 gigs. Vista will see it all.

How should you deal with someone who's very egotistic and thinks they know everything?

Just agree with them, even if you really don't. Eventually they will sense the sarcasm and become angry. At this point you should calmly explain that they might not always be right when they think they are. Sooner or later they will have to agree. By disagreeing with them, that's just what they want and live off drama and the mere fact of being right. Don't go there. Smile, nod, and then I suggest you stay away from a person like this. Just sort of fade away from the person. If it's a mate or a dear friend, then you are going to have to tell them like it is and don't pull any punches!

What is the fastest CPU I can use on a dell dimension 2400 at present it has a Pentium 4 2ghz Also what is max ram i can install on it?

Hi there, the maximum CPU varies, according to if its a P4, or celeron CPU..

Intel Pentium 4 that runs at 2.266, 2.4, 2.53, 2.66, 2.8, or 3.06 GHz.

Intel Celeron that runs at 2.0, 2.2, 2.3, 2.4, 2.5, 2.6, or 2.7 GHz .

The maximum ram is 1gb, in 2 x 512Mb sticks. Of either PC 2100, or 2700 non ECC

Hope this helps

Actually, the maximum RAM is 2GB, not 1GB. It can take pc2700 or pc3200 184 DIMM memory, up to 1GB in each slot. Not sure about the PC2100; (I use pc2700 in mine.) Hope this helps!

Apoette

My sincere apologies, but Apoette, is correct. One of the sites I looked at, stated the max mem of 1gb. After checking crucial's website, Apoette's findings are correct.

Once again my apologies for not checking more thoroughly before posting.

Difference between RAM nd RAM?

Do you mean the difference between RAM and ROM? If that is what you meant then ROM is what is used to read discs that are put into the computer, but RAM is used to temporarily hold memory from desktop and web based applications.

1 kilobyte is 1000 bytes. what fraction of a kilobyte is 450 bytes?

450/1000=45/100 so now you have to find what 45 and 100 goes into.... 5.... so its 9/20 and you can't cancel that down any more so thats your answer.

How do you refresh RAM without restarting your computer?

Can ROM be rewritten by the computer user?

Some ROM chips, especially "Flash ROMs", can be rewritten by the user, often without special tools. Most ROMs are immutable, however.

Why cache memory is called internal or main memory?

Catch memory is internal memory to do the work it can stores the given input to the system

Does data stored on ram is not erased when the power is switch off?

RAM requires a constant voltage to retain information. So by turning the PC off, all data in the RAM is lost.
