In a big-endian system, the most significant value in the sequence is stored at the lowest storage address (i.e., first). In a little-endian system, the least significant value in the sequence is stored first. For example, consider the number 1025 (2 to the tenth power plus one) stored in a 4-byte in<img src ="http://blog.csdn.net/lengxingfei/aggbug/1932534.aspx" width = "1" height = "1" />Thu, 13 Dec 2007 18:03:00 +0800lengxingfeihttp://blog.csdn.net/lengxingfei/archive/2007/12/13/1932534.aspx#Feedbackhttp://blog.csdn.net/lengxingfei/archive/2007/12/13/1932534.aspxlengxingfeihttp://blog.csdn.net/lengxingfei/archive/2007/12/03/1914576.aspxhttp://blog.csdn.net/lengxingfei/comments/1914576.aspx0http://blog.csdn.net/lengxingfei/comments/commentRss/1914576.aspxhttp://tb.blog.csdn.net/TrackBack.aspx?PostId=1914576Kate Lorenz, CareerBuilder.com Editor Five Tips Even if your idea of working out is watching the ESPN without a remote, you can still train to be a top competitor at the office.
