1, first, K and K case is no difference (kilo), M and M is the same 2, B is a bit, that is, a bit, B is a byte, that is, Byte, 8bit =1byte, a letter a byte, a man two bytes 3, 1024B =1KB,1024KB=1MB,1024MB=1GB,1024GB=1TB Answer 1: Why 200M Broadband in the network transmission speed also did not reach 200M. Because b in 200Mbps is lowercase, equivalent to 25MB PS Q-2:KB,

The size of the computer stores information, the most basic unit is byte, a Chinese character consists of two bytes, letters and numbers are composed of a byte. Units of capacity are from small to large: bytes (B), KB, MB, GB, TB. The relationship between them is. 1tb=1024gb 1gb=1024mb 1mb=1024kb 1kb=1024 bytes Usually people use the simple name, the back of the "B" removed, so you ask the 1GB is 1024

Calculates the size of the folder, including subfolders, formatting the output folder size, number of files, and the number of subfolders. The code is as follows Copy Code ?Code can also be used to statistic the number of directoriesFormat output Directory size unit: BYTES,KB,MB,GBfunction Getdirectorysize ($path){$totalsize = 0;$totalcount = 0;$dircount = 0;if ($handle = Opend

Having stayed at school, I went over PhP and looked at the previously written functions. I suddenly wanted to write the known file size and sort the data. For example: 1.3G, 153 MB, 458kb, 998 m, 0.99g (the difference between MB and MB is not considered here, and generally does not involve the operation of

The smallest base unit is byte. Not many people do not know, the following first in order to give all units Byte, KB, MB, GB, TB, PB, EB, ZB, YB, DB, NB I only know the top five, and most people know that, according to the rate of 1024 calculation 40 1tb=2 byte=1099511627776 Byte of the second order 1pb=2 's 50-time Square Byte=1125899906842624byte 60 1eb=2 byte= 1152921504606846976 Byte of the second order

What is the storage unit of a computer? Computer storage units are generally expressed in bit, Byte, KB, MB, GB, TB, PB, EB, ZB, BB, We often refer to the byte abbreviation as B and ask K for the KB abbreviation. What a few k, what a few B. Two, what is their conversion relationship? 1, the smallest unit in which the computer stores information: bit bit (

In the computer newspaper, the Dutch bank's 20 data centers have about 7PB of disk and more than 20PB of tape storage, and the annual growth of 50%~70% reserves, So want to see how much PB, calculate 27pb about 400,000 80 of the hard disk size. 1Byte = 8 Bit (0,1) 1 KB = 1,024 Bytes (size of a shortcut) 1 MB = 1,024 KB = 1,048,576 Bytes (size of a floppy disk) 1

The size of the php statistics file, which is measured in GB, MB, KB, and B. Use the filesize () function command to calculate the file size. the value 1 must be an output of GB, MB, KB, and B. 2. the order of magnitude must be greater than 1 and less than 1024, and two decimal places must be retained. use the filesize

1 TB = 1024 GB 1 GB = 1024 MB 1 MB = 1024kb 1kb = 1024 byte note: byte means B, that is, byte KB is a kilobytes of MB, that is, GB is a Gigabit, that is, a gigabit. Generally, they can be viewed as a kilobytes of data, the accuracy is that 1024 is the 10th power of 2. In the unit of storage capacity, bytes are the most
