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.

1.9 ghz processor with 2 gig of ram is this enough processor power or not?
1.9ghz is a bit low to be honest. You should probably be looking for something in and around the 2.5ghz mark and even then, if your budget allows it you could probably go for something around 3ghz. 2 gig of ram is fine. If its XP that's pretty good, you wont have much trouble with that, if its vista its still fine, but it wont be just as good. But 2 gig is fine.
How do you get a Toshiba 460cdt laptop to detect RAM?
You need to put the proper RAM in place. Otherwise it will not be detected no matter what. It is a SODIMM, maximum 128MB.
Question: Program binaries in many systems are typically structured as follows.
Code is stored starting with a small fixed virtual address such as 0. The
code segment is followed by the data segment that is used for storing
the program variables. When the program starts executing, the stack is
allocated at the other end of the virtual address space and is allowed to
grow towards lower virtual addresses. What is the significance of the
above structure on the following schemes:
a. contiguous-memory allocation
b. pure segmentation
c. pure paging
Answer: 1) Contiguous-memory allocation requires the operating system
to allocate the entire extent of the virtual address space to the program
when it starts executing. This could bemuch higher than the actual
memory requirements of the process. 2) Pure segmentation gives the
operating system flexibility to assign a small extent to each segment at
program startup time and extend the segment if required. 3) Pure paging
does not require the operating system to allocate themaximum extent of
the virtual address space to a process at startup time, but it still requires
the operating system to allocate a large page table spanning all of the
program's virtual address space. When a program needs to extend the
stack or the heap, it needs to allocate a new page but the corresponding
page table entry is preallocated.
Can you use Kingston 1GB ddr2 667MHz on a P4VXASD2 motherboard?
Im afraid this is not possible. This motherboard takes DDR and / or SD ram, not DDR2.
Both SD and DDR can not be used at the same time. IMHO DDR would be the better choice.
Max allowed would be 2Gb (ddr 266 or ddr 200 buffered)
Max allowed is 1Gb, unbuffered.
Hope this helps

ATmega 168 was a flash program memory from ATMEL; now replaced by ATmega 168PA.
What is the major difference between SIMM and RIMM memory modules?
Simm = Single In-line Memory Module.
Dimm = Dual In-line Memory Module.
Rimm = RDRAM In-line Memory Module.
Simms were common from the early 1980s to the late 1990s. Simms and Dimms are very similar, except that Dimms have electrical contacts on each side of the module, while the contacts on SIMMs on both sides are redundant. Also, Simms are 32bit, Dimms are 64bit.
Rimms are obsolote, and were only used by very few Intel Pentuim 3 based motherboards, and early Pentuim 4 motherboards, and while perfomace was good, they were over 3 times the cost of similar SD Ram (Dimm) ram sticks. That, and the manufacturer of RDRAM Rimms taking various other companines in the Ram market to court are ther main reason why RDRAM is no longer used.
What are computer bytes of memory and name the various bytes sizes?
Bytes of memory are chucks of code that help put a program or file together. The largest we have so far is petabyte then going down in size are: terabyte, gigabyte, megabyte, kilobyte, then just byte, then even smaller is a bit.
What is the difference between DRAM and SRAM in terms of characterstics such as size?
•Dynamic cell (DRAM)
-Simpler to build, smaller
-More dense
-Less expensive
-Needs refresh
-Larger memory units
•Static (SRAM)
-Faster
-Cache
When dealing with computers, there are typically two types of memory.
"Real" or "physical" memory is the same thing as RAM. They usually come as cards that you can install into slots on your computer's motherboard.
"Virtual" memory, also known as "swap space" or (in Windows) a "paging file" is a dedicated partition or (in Windows) a file on your hard drive that acts like physical memory does.
Even though both types of memory do the same thing (that is, storing things temporarily for easy access), physical memory is substantially faster than the typical hard drive. Don't consider virtual memory a replacement for RAM, but more of a complement - to catch the overflow, if you will.
What is ram and its primary function in a computer?
Random Access Memory (RAM) - is a temporary storage space used by the computer. While it's switched on - the computer uses its RAM to perform the tasks and operations that the programs ask it to do. When you switch off the computer - the data is lost.
What is more important in a laptop the processor speed or the amount of RAM?
they both play an important part. The faster the CPU the faster it can process the info. The more ram you have the more the OS can load into it and provide faster access. nether one is really more important then the other. No in terms of upgrades, i would go more RAM before new CPU. just for the simple fact that more ram will increase the speed of the computer alot more then the CPU would
How much RAM memory should you get in a new laptop for routine home use?
To run windows XP and Mac OSX they recommend a minimum of 128MB of RAM. However for optimal performance they recommend 256MD for windows XP and 512MB for Mac OSX
What is the definition of memory SDRAM?
The acronym "SDRAM" stands for synchronous dynamic random-access memory. It is a computing term which simply refers to the memory chip contained within a computer.
Can having a small amount of RAM cause a computer to freeze up?
It could mean a slower computer if you have a lot running at once and/or your computer is old. Also depends which programs you are running. Adding more RAM is very helpful for reaching your computer's maximum potential.
What kind of computer memory is both static and nonvolatile?
The Hard Disk installed in your computer is static and non volitile
A regular mp3/song on a computer is about 4 or 5 megabytes. To explain a gigabyte, the conversion is 1000 megabytes = 1 gigabyte.
So 223 gigabytes is a lot of memory. A lot of songs, pictures and other goodies
Your average picture is from around 1 to 2 megabytes
Smallest to largest size it goes; byte, kilobyte, megabyte, gigabyte... each converting by 1000
Hope that helped even slightly =D
What is personalization memory technique?
think of whatever you're trying to remember in terms of your own life(=
What computer memory is essentially empty?
The Random Acess Memory (RAM) is always emptied after AC/DC power to the computer is lost. Most of the times, it may only take 2 seconds, but depending on temperature, it can vary - if temperature is extremely high or low, then it can take a number of minutes. So essentially, there is no such thing as RAM when the computer is off, except for the physical bits of it.
How can you tell how much virtual memory your computer has?
Virtual memory is determined by 2 factors. First, the amount of free hard drive space available on your hard drive. Secondly, it is determined by your virtual memory settings under Windows properties. Assuming you have not changed your Windows default settings, then every ounce of free harddrive space IS virtual memory.
A brownout is a complete power failure?
A brownout refers to the drop in voltage in an electrical power supply system. A blackout, on the other hand, is the complete loss of electric power in an area.
