what is the difference between Mb and MB?

Mega bits and Mega bytes ??\n\n1 byte = 8 bits

"Gb's" would refer to the size of the hard drive, generally. Most laptops tend to have a 40 or 60 GB hard drive. It's more than likely that you'll never fill a hard drive that big, so if it has 40, don't worry too much. \n\nThe previous commenter was referring to RAM. Most laptops will run perfectly fine with 512MB of RAM, which is less than 1 GB. You'd only need that much if you were doing high-end gaming.

No, not millibytes, megabytes!\n\nIn computer science, a byte is the smallest storage size and is 8 bits, 8 ones and zeroes.\n\n1 byte (B) = 8 bits (b)\n1 kilobyte (kB) = 1024 byte = 2^10 byte\n1 Megabyte (MB) = 1024 kB = 1048576 B = 2^20 byte\n1 Gigabyte (GB) = 1024 MB = 1073741824 B = 2^30 byte\n1 Terabyte (TB) = 1024 GB = 1099511627776 B = 2^40 byte\n\nin common mathematics, it is just a little bit different (but almost the same):\n\nnano = 0.00,000,000,1 = 10^-9\nmicro = 0.00,000,1 = 10^-6\nmilli = 0.00,1 = 10^-3\ncenti = 0.01 = 10^-2\ndeci = 0.1 = 10^-2\nkilo = 1,000 = 10^3\nMega = 1,000,000 = 10^6\nGiga = 1,000,000,000 = 10^9\nTerra = 1,000,000,000,000 = 10^12

A megabyte is 1024 kilobytes. RAM is random access memory. Everything you do on your computer goes through RAM. 256MB is the bare minimum for most modern operating systems. You can buy 128MB modules, but for a few bucks more you can gat 256MB modules. Price is dependent on the system. Is it a PC or Mac? Laptop or desktop? What brand? Do you have any open memory slots? What type/speed of memory? If you go to my link, you can do a memory search.

100 KB === 0.1 MB\nKB == Kilobyte (1000 bytes)- 1 thousand bytes\nMB == Megabyte (1000000 bytes) 1 million bytes\nGB == Gibabyte (1000000000 bytes) 1 billion bytes\nTB == Tetrabyte (1000 Gb)

1MB is 1000 kilobytes in theory (SI prefix)\nHowever, 1MiB (binary megabyte, not SI prefix), is 1024KiB.\n\nIn more simple terms: byte = 8 bits, kilobyte = 1024bytes, megabyte = 1024kb and so on.

8 bits =1 byte\n1024 bytes=1 kb\n1024 kb= 1mb\n1024 mb= 1gb\n1024 gb= 1tb(tera byte)

no it's wrong, \n\n1024 bit = 1 Kibibit (Kib), not 1 kilobit (Kb)\n1024 byte = 1 KibiByte (KiB), not 1 KiloByte (KB)\n\nThere is a new standard that the SI prefixes of Kilo, Mega, etc is returned to 1000 even for bit and byte counting, while a new prefixes, which is kibi, Mebi, Gibi, , etc is assigned for 1024 prefixes. These new prefixes is to avoid confusion that is happening between harddisk manufacturer that obey SI values (1000) and other hardware and software manufacturer that want to ease themself by using 1024, which is relatively easier to count for a PC than 1000. \n\nNote: Harddisk manufacturer originally sells harddisk in the usual SI values since that is for marketing purposes since if for example a 10GB harddisk, is actually 9,7 GiB. If they uses the 1024 values, their harddisk capacity would seems to be smaller.

500 Gig is stated using 1000 MB to a gigabyte.  The computer uses 1024 MB to a Gig.  so you lose a bit in the translation.  \n\n24*500= 12,000 MB lost to translation.  or, 11.71GB\n\nalso, a certain % of sectors will be defective on every hard disk.  its normal and every drive will not rate as high as stated on the box.  check with your manufacturer to determine whether or not your within acceptable limits of defect.

bahamadude is correct there are 1024 kilobytes in a megabyte.\nKilobyte is bad since it has a double meaning, kilobyte can mean 1000 or 1024 , but when refering to memory everyone should assume 1024 since memory is ussualy in power of 2's in otherwards 32768 kilobyes = 32 MB (or MiB)of ram.\n\nread this artical at wiki\nhttp://en.wikipedia.org/wiki/Binary_prefix\n\nTo expand \n1 kilobyte = 1024 bytes.\n1 megabyte = 1024 kilobytes\n1 gigabyte = 1024 megabytes

There are 1024 gigabytes in a terabyte.\n1 bit (binary digit*) = the value of 0 or 1\n8 bits = 1 byte\n1024 bytes = 1 kilobyte\n1024 kilobytes = 1 megabyte\n1024 megabytes = 1 gigabyte\n1024 gigabytes = 1 terabyte\n1024 terabytes = 1 petabyte\n(Yeah right! Is there a hard drive big enough?)

one 0 or one 1 is called a bit.\n8 bits = 1 byte.\n1024 bytes = 1 kilo byte\n1024 KB = 1 mega byte\n1024 MB = 1 giga byte\n1024 GB = 1 Tera byte (IIRC) \n\nEvery thing is absolutely true but we cant treat or measure even by 1000 bytes = 1 kilo byte or some thing like that as said by Mr. Charles W. 1024 has its significance. These are the standard measurement units. But as far as I know we can't treat even by using 1000 instead of 1024.\n\nLet me get into the details for making it more clear. The basic thing that we know that data is transmitted or stored in the form of 0's or 1's. Many of them said it as 2^10 but why only 2 raised to some power, why not 3 or 4 or 5? This is cos we use only 2 bits that is 0's and 1's. So we represent the series of data that is transmitted or the amount of data been stored only to the power of 2 not any other number and hence we use as many said 2^10 that sums up to 1024. So I think this is why ever time we say 1024 bytes and we need to say it as it is if we need to represent the amount of data been transferred or stored.

There are 1000 MB in 1 GB   So 512MB would be the same as about .5GB.   The 2GB is much bigger. \n\nGood luck and Happy Computing!
