This definition is used in hard drives, portable memory drives (memory cards, USB drives), DVDs, Blu-ray disks, and most measures of performance. Some software (such as Mac OS X and the Linux kernel) uses this definition when displaying file and disk sizes.

MB stands for megabyte. Mb with lowercase b is ambiguous, as it has been used for both "megabyte" and "megabit". Writing megabytes as MB and megabits as Mbit avoids any confusion.

Using the non-standard definition:

• 1 megabyte (MB) = 1024 kilobytes (KB)
• 1 gigabyte (GB) = 1024 megabytes (MB) or 8192 megabits (Mb)

• 1,000 megabyte (MB) = 1 gigabyte (GB)
• 1,024 mebibyte (MiB) = 1 gibibyte (GiB)
• 1 megabyte = 8 megabits
• mega- = 1,000,000
• giga- = 1,000,000,000
• mebi- = 1,024 × 1,024 = 1,048,576
• gibi- = 1,024 × 1,024 × 1,024 = 1,073,741,824

first u change the BIOS battery and restart the PC in last known config mode.

Also can try removing RAM chips and re-seating them.

I DISAGREE COMPLETELY! First of all the person who answered this question doesn't know what kind of PC you're using or how old it is. They don't know what OS you're using or what level of comfort you have troubleshooting in such sensitive areas. Your best bet is to visit a site that has the credentials to answer your question. After you give them ALL the info about your pc - i.e. brand & type, (laptop or pc) age, your CPU and which OS you're using. Then they can give you educated and SAFE suggestions. If you mess with the Registry or BIOS and don't know what your doing you could really do irreperable damage. You may not have to but If you make a post on any site you should state your comfort level of fixing this issue yourself.

The fact that you came here for an answer (instead of going to a tech site or googling the error) tells me that you're not at the level that's required to do the instructions above. (Besides I'm sure neither one of those areas are the problem) I know you're using Windows so here are some links to go to where you will get a much better answer. Don't forget to give them the info they need about your pc. BTW - Winlogon.exe is the application that logs you on/off the system. It has nothing to do with the BIOS and using a Registry Cleaner is very dangerous if you're not familiar with Registry values. Even the ones that tell you to let the program do the "cleaning" is dangerous - 90 percent of the time they remove files that are needed to keep your system stable. DON'T EVER USE A REGISTRY CLEANER UNLESS YOU KNOW & UNDERSTAND REGISTRY VALUES.

Don't worry this problem is fixable. It's usually caused by security issues (virus, trojans, etc) that have caused damage to one of your volume drives OR faulty hardware like RAM or Hard Disk Drive (HDD). You'll probably have to do a chkdsk fix which is pretty simple, but Changing your BIOS or messing around in the Registry will not help. You could just pull up the event - go to your events monitor - find the event, r-click on properties and when that pops up at the bottom there should be a direct link to the Windows online event help. From there you can go to the Tech Library or try the related links below.

Or, check out the link to the Windows forum - you will have to choose which OS (XP, 7, VISTA, etc) forum you want from there. You'll have to register and then they will validate to make sure you've got a legitimate Windows OS.

After that do a search for your propblem by typing in 'Winlogon.exe Error' in the search box. If you can't find one then start a new thread. GOOD LUCK

5 Million kilobytes = 5 GB

There are 1024 kilobytes in a megabyte. and 1024 megabytes in a gigabyte.

Technically 5000000 kilobytes exactly equals about 4.7498GB.

Also, 5GB exactly equals 5242880KB, which is greater than 5000000KB.

So if you where trying to partition a hard drive, and specified 5000000KB and expected to see 5GB, but found 4.74GB, this could explain why.

Note: Most formatting programs align partitions on a specific KB block, such as 4KB. A 5000000KB partition could be altered to be a different KB size.

That depends on the character code used:

• baudot - 5 bits per character - 320 bits
• FIELDATA - 6 bits per character - 384 bits
• BCDIC - 6 bits per character - 384 bits
• ASCII - 7 bits per character - 448 bits
• extended ASCII - 8 bits per character - 512 bits
• EBCDIC - 8 bits per character - 512 bits
• Univac 1100 ASCII - 9 bits per character - 576 bits
• Unicode UTF-8 - variable bits per character - depends on the characters in the text
• Unicode UTF-32 - 32 bits per character - 2048 bits
• Huffman coding - variable bits per character - depends on the characters in the text

There are actually two answers to this, depending on what method you want to use to determine the answer.

Standard definition The standard definition for kilobyte is 1,000 (10^3) bytes, just like there are 1,000 meters in a kilometre.

Likewise, the standard definition for gigabyte is 1,000,000,000 (10^9) bytes. Dividing, this means there are 1,000,000 (1 million) kilobytes (kB) in a gigabyte (GB).

This is the definition used for hard drives, portable memory drives (memory cards, USB drives), DVDs, Blu-ray disks, and most measures of performance. Some software (such as Mac OS X and the Linux kernel) uses this definition when displaying file and disk sizes. Memory manufacturer usage Memory manufacturers use a non-standard system that conflicts with the way everyone else measures. By their definition, a kilobyte (written "KB") is 1,024 (2^10) bytes, and a gigabyte (written "GB") is 1,073,741,824 (2^30) bytes.

The correct name for 1,024 bytes is "kilobinary byte" or "kibibyte". The correct name for 1,073,741,824 bytes is "gigabinary byte" or "gibibyte".

This is approximately equal to the above, but you may need to know it to figure out exact numbers:

By this definition, 1 "GB" = 1,048,576 "KB" More correctly, 1 GiB = 1,048,576 KiB

This definition is used by memory manufacturers and some software, like Microsoft Windows.

To answer your question, let's make something clear: there can be four different things meant when you ask about "different types":

1. Different technologies: for instance, SDR (Single Data Rate), DDR (Double Data Rate), DDR2 (2nd Generation Double Data Rate), etc.
2. Different speeds: within a given technologies, the RAM can be built to run at different speeds: 800Mhz, 1066Mhz, 1333Mhz, etc.
3. Different features: RAM designs have a bunch of other properties, depending on their target audience. Things like ECC (Error Correction), being buffered or unbuffered, are the major extra features.
4. Different hardware: even if two pieces of RAM have #1 - #3 all the same, it is possible to construct the RAM itself from a variety of different physical chips. For instance, a 1Gbyte RAM module can be made using 8 x 1Gbit chips, or 4 x 2Gbit chips, or 2 x 4Gbit chips.

The short answer to this question (which will satisfy 99% of all computers), is that a computer can use only a single technology and feature set, can use speeds equal to or GREATER than your existing RAM, and can normally use different hardware designs within that technology and feature set.

For instance, the vast majority of systems which are sold as "desktops" (NOT workstations or servers), use a single type of SDR, DDR, DDR2, or DDR3 RAM (these days, it's DDR3, with DDR2 common for machines made in the last 5 years), with the feature set of NO ECC, and NO buffering ("unbuffered"). Very, very briefly around 2000-01, there were some of systems made that had BOTH SDR and DDR sockets - however, only ONE of those two sets of RAM sockets could be used at once, so it wasn't possible to use DDR and SDR RAM at the same time. Systems can use any speed of RAM, but will run at the LOWEST speed of any DIMM used - so, if you have a mix of 800Mhz and 1333Mhz DIMMs, the system runs at 800Mhz.

Please check your motherboard or system documentation. It will explicitly lay out the combinations of the four factors above that can be used in your system. If your motherboard manual doesn't explicitly say it can be used, then DON'T assume it works. If you are unsure, ask your local computer repair store - they'll know for certain.

The prefix mega- means "1 million", and a byte is usually made up of 8 bits, so:

• A megabit (Mbit) is
  • 1,000,000 bits
  • 1,000 kilobits (kbit)
• A megabyte (MB) is
  • 1,000,000 bytes (B)
  • 1,000 kilobytes (kB)
  • 8,000,000 bits
  • 8,000 kilobits (kbit)

In some contexts, people in the computing and information technology industry use the prefix mega differently. Because digital computing is based upon a binary numbering system, mega- in many cases meant 1,048,576, while in others it meant 1,000,000.

With the increase in use of, and access to, the technology by persons with little or no education in digital computing, or experience of this historical meaning, the prefixes mega- and kilo- etc. became confusing because of their ambiguous meanings.

With the increase in storage capacities, the discrepancy between the two measurement systems became much larger and more important, and the old meaning of mega in the binary numbering system is now, therefore, formally known as megabinary.
