Computer Memory

yo mama. dont bring me to this fu3cking page when im looking for the god dam3n answer

This message is caused when Windows encounters a corrupt hibernation file. You can delete the error or try to reboot using that hibernation file. Deleting the file means that anything you had loaded in memory will be gone when you boot into Windows.

Occasionally, Windows seems to "hang" or "lock" when this screen appears. Try a PS2 Keyboard, a PS2 adapter for your Keyboard, or unplugging the keyboard and then plugging it back in.

ROM is Read Only Memory. It holds the codes put there by the manufacture, and is used to start the loading of the Operating System.

One BYTE is currently defined as 8 BITs. (Binary digITs)

1 B = 8 b

(Big "B" is for Bytes and little "b" is for bits.)

Some data protocols use a different number of bits to define a character (like the letter "A"), most systems today use 8 bits, some older systems used 5 bits or 7 bits. But a BYTE is currently defined as 8 bits, since historically the definition of a byte has changed throughout time. Also, one NIBBLE is half a byte, which is 4 bits.

KB -- Kilobyte (official definition now means 1,000 bits per NIST and IEC):

K = Kilo = 1,000

1 KB = 1,000 bytes

1,000 bytes = 1,000(8 bits per byte) = 8,000 bits

KiB -- Kibibyte (new term to avoid confusion with a Kilobyte):

2^10 = 1,024

1 KiB = 1,024 bytes

1,024 bytes = 1,024(8 bits per byte) = 8,192 bits

So, basically, there's still a lot of confusion between IT professionals and manufacturers of data storage devices as not many have adopted the newer Kibibyte definitions. Therefore, you must determine the context and/or do your own math to validate which meaning is being used.

flash memory read only or not

appoximately 3031MB in 2.96GB i think

You cannot, the K701O only allows for 4GB.

Semantic

On most currently available computers there is nothing that checks memory for errors. However some more expensive models use RAM modules having either a parity bit or ECC bits. Parity will detect a single bit error. ECC will correct a single bit error (the next time the location is accessed) and detect a double bit error.

The BIOS ROM might be checked by a precalculated checksum or CRC code value of the ROM image. But I don't know if this is implemented on current computers or not. The helpfulness of this is questionable as the BIOS itself would have to recalulate this checksum or CRC value on itself, if the ROM was corrupted it is possible this routine is corrupted and won't properly detect and report the error.

What is R.O.M.

Yes! Apple Macbook Air Laptops usually have 4GB of ram. The RAM is NOT user accessible. 4Gb of RAM is a great amount of RAM for a standard user.

RAM is for Random Access Memory and it is used as sort of a temporary data holding place for the CPU (Central Processing Unit). It holds the code of the program you are running and data being processed.

4 times as much

Usually 4 GB is the maximum in most recent consumer computers -- although 32 bit Windows can recognize only 3.5 GB or less of the total.

Some machines (Intel i7 based machines, Macs, Xeon based workstations) can take more than 4 GB of RAM if they have a 64 bit operating system (Windows XP64, Vista 64, OSX, Linux) but the motherboard memory controller must be able to support RAM over 4 GB as well as the OS.

Yes, 1GB will run this. Matter of fact, 128 MB of RAM will suffice to run a Pentium 3.

2bits

An PC kept for entertainment purposes would need the large HDD to store audiovisual/multimedia files. These files generally range in size depending on their type but their better quality versions are usually larger in size.

For example: a 3 minute MP3 at 128 kbps (kilobytes per second) is roughly 3 MB large, the same MP3 at 320 kpbs can be 7 MB or larger.

A herd of rams.

Allows you to open applications faster. Gives the computer a boost in accesses time.

2.66" 200-pin DDR2 SDRAM

2.66" 200-pin DDR SDRAM

2.66" 144-pin SDRAM

2.35" 72-pin FPM or EDO

DDR2-SDRAM is the RAM technology that utilizes a 4-bit deep prefetch buffer and operates at 1.8V, as compared to it's predecessor DDR which has a 2-bit prefetch buffer and oprates at 2.5V. Like DDR, DDR2 transfers one bit on the rising and falling edges of the clock cycle. DDR2 takes a step further by doubling the frequency of the bus twice the rate of the memory cells. For example, a motherboard with a 133MHz FSB that uses DDR2-SDRAM for system memory, the RAM would operate at 266MHz, and then give you a 533MT data rate with a theoretical throughput of 4266MB/s.

you need a card reader slot because without the card reader the memory card will not run in the computer. also the card reader slot serve as a software which must be programmed into t he computer.

cant see why not
