 1) computing a unit of storage capacity, 1024 (210) bytes : kibibyte
 2) 1000 bytes, though this is the technically accurate definition as an SI unit.
 3) computing a unit of storage capacity, 1024 (210) bytes : kibibyte
 4) A unit of computer memory or data storage capacity equal to 1,024 (210) bytes.
 5) One thousand bytes.
 6) a unit of information equal to 1024 bytes
 7) a unit of information equal to 1000 bytes

Definitions
 1) One million bytes. SI Symbol: MB
 2) computing 1,048,576 bytes; a mebibyte. Frequently abbreviated MB.
 3) One million bytes.
 4) A unit of computer memory or data storage capacity equal to 1,048,576 (220) bytes.
 5) a unit of information equal to 1024 kibibytes or 2^20 (1,048,576) bytes
 6) a unit of information equal to 1000 kilobytes or 10^6 (1,000,000) bytes

Examples
 1) However, use of Base 2 when using the word kilobyte, for example, is deprecated.
 2) If you change a single kilobyte out of a 30GB file, rsync will swap just that single kilobyte.
 3) Verizon told George Vaccaro that bandwidth charges in Canada were .002 cents per kilobyte, but billed him at .002 dollars, or 100 times as much as he was quoted.
 4) “There was something about so much per kilobyte downloaded, but one really has no idea what kilobytes are used to check an email,” Sehmer says in the Vancouver Sun post, which adds:
 5) The truth is that not a single kilobyte flowing through its modern fibers has yet reached our computers.
 6) That would be plausible if error were a fixed and uniform entity, like a kilobyte or a quart.
 7) In any of these scenarios, remember that going online by mistake can incur perkilobyte charges that might make internationalroaming fees look cheap.
 8) Even "normal" BOL subscribers  who get 256 kilobytepersecond connections  pay $1,500 per month for their subscriptions.
 9) Fees could range up to 4.55 won (0.4 U.S. cents) per 0.5 kilobyte used.
 10) ‘There are 8 bits in a byte, 1024 bytes in a kilobyte, and 1024 kilobytes in a megabyte.’
 11) ‘We used to measure data in terms of kilobytes and megabytes; now gigabytes and terabytes are the terms commonly discussed.’
 12) ‘We used a folder with 893MB of mixed data, with file lengths varying from a few kilobytes to tens of megabytes  1470 files in all, some in the root directory, some in folders.’
 13) ‘By convention, when we say, for example, that a PC has 640K of memory, we mean 640 kilobytes, or 655,536 bytes of RAM.’
 14) ‘The €50 package offers an upload speed of 256 kilobytes per second and a download speed of 1500 Kbps.’

Examples
 1) ‘We used to measure data in terms of kilobytes and megabytes; now gigabytes and terabytes are the terms commonly discussed.’
 2) ‘Here is a quick explanation of bytes, megabytes, and so on, and some estimates of the storage requirements of various sorts of information.’
 3) ‘The software requires only five megabytes of hard disk space and 16 megabytes of random access memory (Ram).’
 4) ‘I've been writing for years about how the price of hard drives has tumbled down to a penny a megabyte and here I was paying almost 20 cents a megabyte!’
 5) ‘The Editor's Internet service provider will not process files larger than two megabytes.’
