Computer Memory

when ram becomes infected by the power supply

By an external battery that is not connected to the PSU and only used for the CMOS RAM, this could be in the form of a Coin cell Battery (a silver coin shaped battery) or a barrel soldered battery.

This is why the date and time settings are not lost when the computer is unplugged.

On your basic common computer today anywhere from 1 GB to 3 GBs is common. For a gaming computer 4 is about the minimum ranging all the way up to 32 which is way overkill.

Ive just been studying about all the forms of SDRAM etc, and when it came to buffered/registered DRAM I found out that normal PC's usually have upto 4 slots for SDRAM, any more gives producers of motherboards lots of electrical problems. So to solve the problem of systems that require maybe 6, 8 slots, they require special DRAM, such as buffered/registered SDRAM. This SDRAM has a special buffering chip on the address bus added to it to work as an intermediary between SDRAM & North Bridge. To take advantage of buffered SDRAM, the motherboard and brige must be able to support SDRAM. Slots requiring buffered DIMMs are keyed differently then those requiring unbuffered DIMMS so it will be physically not possible to install these DIMMs into the slots short of shaving the key. Electrically, possibly, but you have to remember that the register drives the addressing unit on the DIMM and the bridge will likely not be designed to accomidate the drain required to directly drive the memory chips on the address bus and as such may cause instability if it works at all. In addition there is a single clockcycle delay from when the address is written to the registers to when the address is propigated to the memory, in such timing errors could arrise from a bridge expecting that delay.

- you cannot use unbuffered SDRAM on a motherboard that supports buffered memory, because the notches on buffered DIMMS are in different positions than for unbuffered DIMMS.

Ram is used for temporary storage. Ram stands for random access memory.

There are a couple reasons why it won't turn on.

It's not plugged in.

It got wet inside.

Or something isn't properly placed inside.

860 MB is the latest that I know of which is like 100 minutes I think.

The

MAR is a special register in the sense that each time it is accessed from the outside, memory senses it and

considers the new content of the MAR an address.

A megabyte (MB) is 1 million (1,000,000) bytes.

Roughly speaking, this means it can hold 1 million characters.

Strictly speaking, a character can take more or less than 8 bits to store, though, depending on the character and the encoding.

How much memory do I need? How much RAM is currently installed in my system? How many and what kind of memory modules are currently installed on my motherboard? How much and what kind of memory can I fit in my motherboard? How do I select and purchase the right memory for my upgrade? How much memory do I need?

Most likely, as inexpensive as memory is now, your computer could probably use an upgrade. One gig is a standard minimum for windows XP, and two gigs is standard minimum for windows vista. If you have less than these on those OS you may find your computer a little sluggish.

no just a bit sweg

foundest memory is a memory you absolutly never would regret happening

That's a bit like asking how many ounces a glass can hold - there are many different sizes of hard drives. However, the rule for data size conversion is that there are 1024 megabytes (MB) per gigabyte (GB). If it's important to go further, the same rule applies for kilobytes: 1024 kB/MB.

The actual number is 1024 (2^10), but it is often approximated to 1000.

First, let's assume you are talking about modern computers that use the hexadecimal system. {Old systems use octal, and we won't go there in this answer.) The ASCII chart runs from hex 0 to hex 7F, so it takes two bytes to store one ASCII character. {see the Related Link for an ASCII chart} One kilobyte = 1000 bytes, thus 500 ASCII characters can normally by stored in one kilobyte. http://www.asciitable.com/

What 2GB of RAM stands for is 2 Gigabytes of Random Access memory or RAM. These 2 GB of RAM tells you how much total memory can be stored within RAM, all it means is that 2 Gigabytes of total RAM can be stored within the memory of the RAM at at time when accessing desktop applications, and web browsers. The more RAM you have the faster the applications and we browser will run, because more RAM will allow the computer to store more information at a time. Also if you want to get more technical 2GB of RAM equals 2,000 Megabits and 2,000,000 Kilobytes.

No DDR2 and DDR are not compatible and so you can not add DDR2 RAM module in a DDR Slot. Electrical specifications like voltage, signal pinout and even mechanical size and shape of modules are different.

Most likely not when you consider music, photos, apps, etc. 30 GB is the average for phones, but you could probably get way with 15 GB.

Static RAM (SRAM)

1. 4 times more expensive

2. Very low access time

3. Can store ¼ as much

4. Information stored on RS flip-flops

5. No need for refreshing

Dynamic RAM (DRAM)

1. Low cost

2. Consumes less power

3. Can store 4 times as much

4. Information stored on FET transistors

5. Needs to be refreshed

first of all its if NOT is

two seprate module of even same company will give less performance, because they are installed of a same bus, so one module can performa his action while second have to wait. on the other hand single module will give more performance.

RAM stands for Random Access Memory. It is physical memory installed in a computer or storage device as silicon chips, hard disk, floppy disk, CD, etc., that is addressable by, and is directly accessible to, a computer (CPU) in a non-sequential (random) manner.

Some Macintosh Computers made in the last 5 years have an in built memeory card read/writer.

If you you are using the internal reader then inserting the card into the drive, waiting until the card appears onscreen and using the click-and-drag method to copy files from the Mac desktop to the memory card will work.

Should you have an earlier Mac that lacks the internal card drive then pluging the drive cable into the back of the Mac will allow access to the card.

Mac are a bit different to other machines in that draging a disk icon to the trash can will eject the disk
