Yte is a unit of measurement of computer information technology used to measure storage capacity and transmission capacity, with 1 bytes equal to 8-bit binary. At the moment we often calculate the smallest unit of storage space (in fact there is a smaller bit,1 byte=8 bit).However, from the hard disk or called storage space, we use the smallest unit is KB (kilobyte), the size of 2 10 bytes, and byte conversion is: 1kb=1024byteThe conversion of the fut

Http://hi.baidu.com/dilijia1002/blog/item/38f0b5cef747c70d92457eb1.html Byte is a unit of measurement used by Computer Information Technology to measure storage capacity and transmission capacity. one byte equals to eight-bit binary. Currently, we usually use the smallest unit of computing storage space (in fact, there are smaller bit, 1 byte = 8 bit ). However, for hard disks or buckets, the minimum unit we use is KB (kilobyte), which is the 10th byt

"), the computer's representation of many data are binary units, and 1 bits represents a binary digit, only 0 or 1;byte is the most commonly used in the computer unit, 8bit 1byte, Many places with 1b represent 1BIT,1B represent 1byte. 1 kilobyte equals 1000byte (10 bytes, or 1024byte, of 1kilobyte equals 2 for binary calculations in the computer). The conversion of some other units is described below:1 kilobyte
