Storage first you have to be familiar with the computing unit of storage:This is the basis of the university curriculum computer learning computer storage units such as the KB, MB, GB, and so on to represent the storage units.Here's what you need to know about conversions between your units:The unit and conversion rela
Q: Bite,byte,k,m,g and so are storage units, an English account for a few how much space, a number of space, how much space a Chinese character occupies. The database in a table a field B length varcha2 (20) What that means, is how much space is allocated to the field.
For:
1) Bite,byte,k,m,g, etc. are all storage units
Every time the data conversion to check the information, always remember not very clear. It's time to make a summary.
The next two storage units are described: Bits, bytes
Bit: "Bit" is the smallest unit of data in an electronic computer. The status of each bit can only be 0 or 1.
Word: "word" consists of a number of bytes, the number of bits is called word length, different grades of machines have diffe
Computer storage Units
Basic introductionComputer storage units are generally indicated by B,KB,MB,GB,TB,PB,EB,ZB,YB,BB, and there will be larger storage units in the future.Edit this paragraphConversion relationshipThe relationsh
1, the computer stores the smallest unit of information, called bit (bit), transliteration bit, binary of a "0" or a "1" called A.2. The basic unit of computer storage capacity is byte (byte), transliteration is Beit Hanoun, 8 bits compose 1 bytes, a standard English letter occupies a byte position, a standard Chinese character occupies two byte position.3, the size of the computer storage capacity in bytes
Computer storage units: Byte, KB, MB, GB, TB, PB, EB, ZB, YB, DB, NB How much do you know?
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 Bit1 KB = 1,024 By
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 it, according to the rate of 1024 calculation
1tb=2 's 40-Time Square byte=1099511627776 Byte
1pb=2 's 50-time Square Byte=1125899906842624byte
1eb=2 60-Time Square byte= 1152921504606846976 Byte
1zb=2 70-Time Square byte= 1180591620717411303424 Byte
1yb=2 80-Time Square byte= 12089258196146291
