Storage capacity: Is the maximum number of data that can be stored on the storage device, typically using kilobytes (KB kilobyte), megabytes (MB megabyte), gigabytes (GB, gigabyte), terabytes (TB, terabyte), and Pb (Petabyte), EB ( Exabyte), etc. to measure.1Byte (equivalent to an English letter, a kanji account of 2 byte)1kb=2 (b=1024b); Quite a short story.1mb=2 (kb=1024kb=2) B; Quite the text of a short

However, I compared the Pb project of 2440, and found that its ATL was not added, and the compilation was successful, so it should not be the problem. In the C:/program files/Windows CE tools/wce500/system_2440/ATL/include directory, find comdef. h file, which is generated when SKD is installe

Exposure to computers all day, inevitably with a variety of measurement units to deal with, especially data, but you know bit, Byte, KB, GB, TB and so on all means how much data? Have you heard of EB, ZB, YB? Bit (bit) is the initials of binary digit, the unit that measures information, and the smallest unit that represents the amount of content, only 0 or 12 binary states. 8 bits make up a byte (byte), can hold an English character, and a Chinese character requires two bytes of storage space,

Most of these resources are not Chinese. If you prefer to read Chinese materials, you can view them from the bottom up. The Chinese resources are at the bottom. Of course, my personal abilities
