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.

160 GB has absolutely no correlation to Ghz. One is a measure of capacity; the other is a way of measuring the speed of a processor. It's like asking "20 ounces equals how many MPH?"
How many mega bytes are there is a gigabytes?
There are 1000 mb in a gb,
1000 bytes in a kb
1000 kb in a mb
1000mb in a gb
1000 gb in a tb(terrabyte),and so on,never stops!
Put 8 byte size into a 4 byte?
#include <inttypes.h>
int64_t b8;
int32_t b4;
b4 = b8; /* perfectly legal */
What determines what type and how much RAM you can use in the system?
Your motherboard in your PC determines what RAM standard your PC can handle. You can usually find this information on the manufactures website or try a Google search of the make and model of the PC.
Further, most PCs can run any brand of ram as long as the memory standard matches what the system uses.
Most modern PCs manufactured 2006 - 2008 use standard DDR2 memory.
Laptops also have the same speed and standards as desktop memory, HOWEVER, laptop memory is much shorter than desktop memory. (different physical size..)
Higher speed memory is backwards compatible with lower speed memory as long as the same standard is used (DDR, DDR2, DDR3, etc..) Example: if your PCs memory standard is DDR2 533 you should be able to use DDR2 800 just fine. All the installed memory will run at the same speed (lowest spec installed).
DDR2 800 is manufactured in HUGE quantities and is the cheapest memory on the market right now (2008)....
As cheap as memory is right now (4GB DDR2 800 usually goes for about $50) you should max your PCs ram out for best performance. RAM really makes a HUGE impact of how fast your PC performs.
One more thing to think about:
Operating systems can also limit the maximum amount of usable ram. All 32 bit operating systems are limited to a max of 3.5GB of ram. **You will need a 64 bit OS to be able to use more than 3.5GB of ram.** Most XP installs are 32 bit -- XP and Vista both come in 32bit and 64bit. In Windows, if you right click "My Computer" and then click "Properties" you will see how much ram you have installed and if you have x86 (32bit) or x64 (64bit) OS.

Main memory is located on the CPU chip?
The only memory located on a computers CPU chip is called the cache.... typically about 1-8MB in size it acts as a rapid access 'buffer' for immediate actions.
The main memory is usually termed the RAM and sit's nexto the CentralProcessorUnit - connected by the FrontSideBus (board circuitry), size.... well depending on age anything from a few MB to 16GB (dependant on a number of factors).
Actually, the term "main memory" is reserved for the primary location where active work is stored. In modern computers, "main memory" consists of DRAM chips mounted somewhere near the CPU. Thus, "main memory" is never on chip. The reason for this is cost - providing memory inside the CPU is hideously expensive, there is a limit to how much can be put there, and the amount can never change. Off-chip main memory allows very significant cost savings, and allows the amount of memory to be adjusted freely.
There are generally TWO types of memory that are located on-chip, however. Cache memory (which can come in various "levels", describing how far away from the main CPU each memory bank is) is used to keep copies of data from the main memory in a location that is "closer" to the CPU, and thus faster to access and use. Registers are memory located directly inside the CPU's execution units - think of them as scratch space where the CPU can temporarily store small amounts of data while it does a calculation. For instance, if a CPU is asked to do: A+B=C, it will have to load A into a register, then load B into a register, then do the calculation, saving the result into a register, then finally load the "results" register value back into C.
What is the highest RAM size in the world?
About 256 gigs RAM is currently the most a MAC and Windows PC will handle. You would not need any more than this.
"You would not need any more than this." - computer salesmen have been saying that since the first day i walked into a computer store when i was a kid in the early eighties, come on man! If you are trying to push the limits of development you will always need more.
It is a technology that theoretically doubles data throughput from the memory to the
memory controller.
The motherboard has memory slots and if not using all four slots, then they must be placed in a certain configuration for it to use dual channels.
Your motherboard manual has the configuration of memory and slot placement
for this to work.
If running dual, it is best to buy memory that is designed as a pair or a set
to get the most efficiency, it usually says, dual channel kit.
Can you lose RAM on your computer?
Yes, you can sometimes you it can fail and you will have to replace it.
I'm not sure that I understood you right. But security updated don't provide or take away user permissions and rights. Security and account policies are a part of windows. Updated only fixed some problems but don't define rights.
What is the maximum amount of RAM supported in a dell c640?
1gb(if from a good company)..
2gb(if local ram)
asa
In computing, it is Read Only Memory
As opposed to RAM - Random Access Memory
What does indicate the raised albumin?
Raised albumin levels usually indicate that a person is suffering from dehydration. It may also indicate a Vitamin A deficiency.
Yes, it is a lot i don't know what 60gb is, but just think 64gb is 14,000 songs!
What is the max ram you can put in a dell latitude d830?
8 GB is the maximum RAM that you can put in a dell latitude d 830.
What is the definition of byte?
A Byte is a set of 8 bits. a Bit is an on or an off represented by a 0 or a 1
