A double byte is two bytes.
As a 21 byte array of type char (including 1 byte for the null terminator).
Not without casting. A char is a 16 bit type, whereas a byte is an 8 bit type. Therefore the compiler cannot guarantee that the 16 bit value will fit into the 8 bit value without overflowing. If you attempt to stick a char into a byte, you will get a compiler error. To override this, you can cast the char value to a byte during assignment. However, you might get some unexpected results. A few examples below: char a = 'A'; byte b = a; //compiler error char a = 'A'; byte b = (byte)a; //valid, no error. b=65 char a = 172; byte b = (byte)a; //valid, no error, but b=-84 because of overflow.
Java coding uses byte as one of the programming directives to clarify commands. Byte can also be used in the Java code to save memory space when the need arises.
A byte is a single unit of digital information, made of of several bits of sequenced binary data.
Next is PB - Peta Byte. 1 Peta Byte = 1024 TB
There is a exabyte, a zettabyte, and a yottabyte
After terrabytes, you get:petabytesexabyteszettabytesyottabytesPussabytesHertzbytesTriaobytesNo more bytesEach one is 1024 times bigger than the previous unit.

PETA bite
I assume you mean "Petabyte". Check the Wikipedia article on "Metric prefix" for the prefixes, that include "Peta".
1024 petabyte = 1 exabyte. For more info--- 1024 exabyte = 1 zettabyte 1024 zettabyte = 1 yottabyte
Currently, commercial computers (sold at hardware stores to normal customers) mostly contain hard disk that have a capacity around 500 gb, for desktops, and 120gb for notebooks. The 500gb could sometimes even be 1TB for desktops IMPROVED: As of this response (7/21/2010) the largest HDDs in production are 1.5 TB for 3.5" and 4.5 TB for external/array packages. However technology is in prototype with up to 4.5 TB 3.5" available relatively soon (within a couple years). The largest memory modules in commercial production are 16 GB DDR2 sticks, though only 4GB sticks are common for end-users. The largest SSDs available are currently around the 500 GB mark, and rediculously expensive. The largest EEPROMs are 64 MB single-chip The largest SRAM caches are 8 MB single-chip The highest commercial density storage is Blu-Ray with 25 GB per layer (50 GB dual-layer), but with HVDs and PSDs on the way. The largest tape drive is an astounding 12 TB 14.5" tape from IBM The largest Flash single-chip module is 512 MB (of course much bigger can be made combining chips, as almost all flash devices do) Largest SD card is 64 GB Largest single-CPU cache combination structure is 12,928 KB Largest CPU register bank is 4096 bits Largest HDD buffer is 32 MB Largest sequential tape memory is 1 GB Largest video card is 8 GB And that's all I know for the moment. (Whew, that took some research!)
Its not tetra its terra. Its is a measurement in the powers of 10. as you know kilobyte means 1000 bytes A megabyte is a million bytes A giga byte is a billion bytes A terra byte is a trillion bytes then there are peta-, exa-, zetta- and lastly yotta- A yottabyte is: 1,000,000,000,000,000,000,000, 000 bytes.
Peta is 1015.
