Answer:
626 KB is a rather small filesize. It is the equivalent of about 1 picture. 1,024 KB is one megabyte (1MB). A song is typically 3 to 8 MB, or 3,000 to 8,000 KB. Most desktop harddrives today are between 120,000 MB to as much as 1,500,000 MB. Laptops are typically 40,000 to 250,000 MB. 626 KB is such a tiny amount that it's often considered 'negligible'. Or so small it makes no difference. What is listed below is technically correct for BYTES. However a Byte is 8 bits, a a bit (abbreviated as a lower-case 'b' or just 'bit') is the smallest unit of measurement in a computer. Most modern computers however use a filesystem that limits the smallest size of a unit to 512 bytes. So a 1 byte or 1 bit file will both be 512 bytes. This is called a 'cluster'. A cluster may be as large at 64 KB as well. However, for a 626 KB filesize, this is largely irrelevent as it would easily use the clusters efficiently. However having a very large number of files smaller than 512 bytes may waste a lot of space. IE, you could have 100,000 files that are all 1 byte in real size, but they take up a 512 byte size each. Making what would be 100 KB actually take up 51,200,000 KB. Older computers, SD cards, thumb drives, and other USB and flash drives use FAT and FAT32 filesystems, and suffer less of this problem (they can have clusters as small as 32 bytes) Either way though, a single 626 KB file is very, very tiny. It's the eauivalent of just under 1/2 of a floppy drive, or 1/1000th of a CD. Also, TB (Terabyte) is not the largest unit. While very rare to see in a consumer (home user's) computer, there also exist PB (Petabytes), and even EB (Exabytes). Some supercomputer clusters, such as Google, have systems with an EB of storage or more. But there are, at most, a dozen such systems on earth as of this moment (7/31/2010) OLD: no, B is the smallest computer unit, KB is the 2nd smallest, MB is the 3rd smallest, GB is the 4th smallest, TB is the highest computer unit.
