Computer Memory

See, an RAM upgrade will give you the power to run more programs without any lag. If your current computer runs without hanging and you just want a speed boost then you may consider an upgrade in the processor. I recommend you to see Intel i3-3200 processor. It is much better then core2duo and not very expensive.

In HTML (a markup language used primarily for the creation of web pages), the DIV tag defines a division/section in a document.

yes it could possible damage it if you put to much or too little

Yes. (if by p4 you mean a computer with a Pentium 4 processor)

The same way people need blackboard.

To jot specific thing down so they can be manipulated and retrieved faster with the context intact instead of trying to do everything with your brain.

When the process finish the blackboard is cleared.

If a brain is the CPU and harddisk, the blackboard is the memory.

no

That is not a help-full answer when someone needs to know the answer

COM 1 means SERIAL port number 1

"Virtual" memory is computer memory that exists on a fixed media and non-volitile storage device of some kind -- a hard drive, or a solid state drive -- which is used, mostly, for overflow from, or swapping things in and/or out of, regular Random Access Memory (RAM).

The computer comes with three kinds of memory in it: Read-only Memory (ROM), Random Access Memory (RAM), and the "virtual" memory that's created by the operating system on a hard drive or solid state drive.

Hard drives, and/or solid state drives, in and of themselves, are not considered "memory." They're considered mass storage. However, once the operating system is up and running on the computer, and has allocated parts of itself, and of the various programs that are running, into RAM; and has also allocated a certain amount of RAM for calculating and doing things, then it will also allocate a little bit of one of the mass storage devices -- usually a hard drive, but on some of the newer machines with solid state drives in them, it can also be on that -- for what's called "virtual" memory, which is mostly used for RAM overflow... more specifically, for swapping things in and out of RAM.

The computer reads from ROM (usually the BIOS and CMOS chips) at startup so that it even knows that it's a computer; and then, from there, what it has connected to it, and how to use it all.

Then, once the computer has fully booted-up, the operating system loads parts of itself (and some other things) into RAM, and then it allocates part of mass storage as "virtual memory." As RAM starts getting full, the operating system will take the least-used things in RAM and will throw 'em down onto the part of the mass storage device that has been allocated as "virtual" memory. Then, if anything in virtual memory becomes needed up in RAM, again, the operating system will go get it and pull it back up into RAM. Virtual memory, then, is mostly used as "swap" space. It is not, then, actual "memory," per se; but it certainly functions like it.

Virtual memory is also slower than regular RAM: Data cannot possibly be put onto, or pulled from, the "virtual" memory part of a hard drive full of moving parts as fast as it can be moved around RAM, itself. Even a solid state drive, which is a little like RAM in the sense that it's an integrated circuit with no moving parts, is not as fast as RAM. But the operating system knows how to keep things moving, and to only swap things down into virtual memory that really and truly won't be needed as much or as often or as quickly. The virtual memory management parts of most operating systems is pretty sophisticated.

So, then, the answer to the question, "what is the purpose of virtual memory," is that virtual memory (which is always a part of a mass storage device, allocated by the operating system) is primarly used to swap things in and out of RAM so that said RAM won't get so clogged-up and bogged-down.

When one purchases a computer, one reads certain specs about it. For example...

The "processor" (or CPU) may be "dual core" and three-point-something gigahertz (GHz) in speed; or,

The memory (or RAM) will be 4, 6, 8, 12 or 16 (sometimes more, sometimes less) gigabytes (GB) in size; or,

The hard drive (mass storage) will be 500 to 750 gigabytes (GB) (or even one terrabyte, or larger) in size; and, sometimes,

There could also, optionally, be a solid state drive (also considered mass storage) of 32 or 64 GB.

"Virtual" memory is always allocated by the operating system from space on either or both of the hard drive or solid state drive mass storage devices; and said operating system then "swaps" things to/from RAM down to/from the allocated "virtual" memory; thereby keeping RAM from becoming cluttered and slow.

There are two (or maybe 3) different types of memory in a computer. magnetic memory (a hard disk) is used for permanent storage. Data stored on a hard disk stays there until it is erased. however, it takes a relatively long time to access the data on it. RAM (Random Access Memory, semiconductor memory) is much faster than magnetic memory, but has much lower capacity, and loses its memory when the power is removed. Typically, the programs and the data you want to operate on are stored on the disk, for example, a word document and the word program. When you want to edit the word document, both the document and the program are copied from the disk to RAM. There the computer, under your control, performs the edits you want to perform. When you are done with the document, you "save" and the document is copied from the RAM to the disk (written), replacing the older copy there. When you exit the word program, it is deleted from RAM. A copy still exists on disk for next time. This is a simplification, as there are several levels of RAM, very fast and small for the immediate operations of the CPU and not as fast and large for operations a bit less used. There is also ROM, EEROM, magnetic tape, CDs, all other types of memory.
RAM is used to temporarily store data that is retrieved from the use of desktop applications and web browsers. RAM is the main reason why an application or browser is able to run until you want to close it. Without RAM it would be impossible to run any applications, games or, internet browsers on a computer.

Yes sd ram have two cuts

That's actually two questions. See the related questions below for links to the answers to each of those questions.

It declares to system BIOS at startup the module's size, speed, voltage, and data path width.

L3 cache is sometimes found on the mobo. It can also be built into the CPU. There is also the possibility of a L4 cache being built onto the mobo in the future.

Unfortunately, this is kind of like asking "is my mailbox the right size or should I buy a larger one at Home Depot?" It all depends on how you use it. If you are running Windows 7 on your computer, then 6GB is the minimum amount of RAM that I would recommend. In the case of Windows 8, I recommend at least 8GB. (The software minimum requirements as published by Microsoft are lower than that but adhering to the minimum standards is similar to saying. "Well, I can use a car to get to where I'm going but I can do the same on a skateboard, so I'll go by skateboard instead." It gets the job done but not as effectively or efficiently.)

Now, if we presume for a moment that you are using Windows 7 and the choice is whether to keep 6GB or move up to 8GB, then we need to consider what you generally do with your computer. If, for example, you are a typical home user who browses the Internet, watches a few YouTube videos here and there, and writes emails but really doesn't do much else, then 6GB should suit your needs just fine. However, if you are a more intense user who likes to have several things up and running at the same time (such as Google Chrome, Mozilla Thunderbird, MS Outlook, Quickbooks/Quicken, VLC Media Player, etc.), then 8GB would probably be the better choice as it would give your computer more breathing room to run all your desired applications and still have enough room for its basic Operating System functions without having to start swapping anything in and out of virtual memory (which is nothing more than a file on the hard drive and is literally one million times slower than RAM as hard drive access is measured in thousandths of a second while RAM access is measured in billionths of a second).

So, given this information, the best decision for you should be easier for you to make. However, if you need any further advice or pointers, feel free to drop me a line and I will be glad to assist you further.

Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data, it looks first in the cache memory and if it finds the data there (from a previous reading of data), it does not have to do the more time-consuming reading of data from larger memory.

Conceivably, if you were right at the point of maxing out your old power supply and you gained additional speed by having more ram, you might increase the power demand ever-so-slightly by allowing the computer to function faster. Possible but not likely. While you have the case open, it wouldn't hurt to blow dust out of the power supply. Overheating because of dust buildup is as hard on it as anything.

"Anda Setuju?" comes up as a Javascript pop-up box in front of a garish green website. This tells you your computer is infested with the Brontok computer worm. If this happens to you, select ctrl + alt + delete to bring up Task Manager, and then End Task. Then get back into your internet and google ways to remove Brontok from your system. Judging by the poor spelling on the Brontok webpage, "Anda Setuju?" probably means "And Setup?", so don't click OK on the pop-up box.

yes

On the desktop or in the start menu, right click My Computer and then Properties. The RAM is listed there. It may take a second to show up. I'm not sure what you mean by ROM, but if you mean hard disk space (I'm assuming), left click on My Computer and right click the C: drive and click properties and it should show the total amount under Total Size.

Memory Map is a list or a table which shows starting/ending address and range for various memories and peripheral/device registers on a processor bus. It is a useful document for any microprocessor/controller based product development.

It will either have no effect (if there is enough RAM in the machine at the moment) or improve performance (if there is not enough RAM in the machine at the moment).

Therefore you could be wasting your money. Before purchasing more RAM you need to diagnose what (if anything) is the bottleneck in your computer.

-------------------------------------------------------------------------------------------------------

Essentially, the RAM is used to provide temporary storage for data that will be used by the processor in the computer. If there is not enough space in the RAM to store this data, the hard disk will be used to store this temporary data.

So by that logic increasing the RAM will improve the performance of your computer as accessing data from the RAM is faster that the hard disk.

However, the maximum amount of RAM that a computer can use depends on the operating system that you are using so find out the maximum amount supported and if you can afford it max out the RAM.

---------------------------------------------------------------------------------------------------

Any currently running programs are stored in RAM. If there is no more room there, then they get stored in the swap buffer on the hard drive, which is a lot slower. But even if you aren`t doing anything, Windows still constantly tries to access it`s memory in the swap buffer and that slows everything down.

So when you add RAM, you give the computer more space to store the active programs and avoid dipping into swap as much.

Well as of now, I'm sure that you would need a relatively high amount because I'm sure that even Windows 2000 can run that application. So if you can run Windows 2000 or up, you have enough RAM.
