1. Bytes:
The word (Byte) section is the length unit. Bit (bit) is also the unit of length.
Because computer communication and storage is based on 010101 of such binary data, where a 0 and 1 of the place is called bit (bit), that is, a bits.
1byte=8bit
1kb=1024b
1MB=1024KB (2 of 10 Parties)
2. Binary
Binary number has two features: it is composed of two basic character 0,1, binary number operation law is every two into one.
In order to differentiate f
Scenario: In development, to combine multiple []byte arrays into one []byte], the initial implementation is as follows: 1. Get multiple []byte lengths 2. Construct a two-dimensional code array 3. loop copies []byte to a two-dimensional array Package Gstoreimport ( "bytes")//bytescombine Multiple []
/** String (byte[] bytes, string charsetname): Decodes a byte array by the specified character set* byte[] GetBytes (string charsetname): Encodes a string into a byte array using the specified character set** Code: To see the understanding of the changes can not understand* String--
Byte order and size end, byte order size endWhy is there a byte order problem?
1. memory uses 8 bits as an address unit: the early processor address uses 8 bits as a unit (8-bit processor). That is to say, 8 bits of data can be accessed at a time, and then 16 bits are generated, 32-bit or even 64-bit processors, but to be compatible with the oldest 8-bit processo
The basic data types in java include byte. byte stores integer data, which occupies 1 byte (8 bits). The data storage range is-128 ~ + 127.
Byte is a class in java. lang to encapsulate the basic data type byte. Encapsulation has several advantages, such as: 1.
Byte streams are very similar to bytes streams.In addition to operationsCodeIn addition,Are there other differences?In fact, the byte stream itself does notThe buffer zone (memory) is used for direct operations on the file itself, while the swap stream uses a buffer zone during operations and operates through the buffer zone.Composition,.
The following compares the write operations on two files, but does
In java, the difference between write (byte [] B) and write (byte [] B, int off, int len) is: bytelen

Byte and byte[] Array, "represents a 8-bit unsigned integer, typically a 8-bit binary number."Byte is the most basic storage unit and the most basic communication unit of a computer.Why is it that byte is the most basic type?In fact, the key is that the computer's most basic algorithm is coding, including media files,

BPS is the abbreviation for bits per second. The transmission rate of general data machine and network communication i
Bit means "bit" or "bit", which is the basis of computer operation and belongs to the areas of binary system.
byte meaning is "bytes", is the computer file size basic unit of calculation;
The two applications are different. Bit is usually used as the unit of data transmission, because the physical layer, the data link layer transmission is transparent to the user, and this communication transmission is based on binary transmission. In the application
The byte stream processing unit is two bytes of Unicode characters, operating characters, character arrays or strings respectively, while the byte stream processing unit is one byte, operating byte and byte array. Therefore, the compaction stream is a character that is conve
Byte order refers to the order in memory of data that occupies more than one byte of memory, usually with a small, big-endian byte order.small-endian byte-order refers to low-byte data stored at low memory address, high-byte data
I have never tried to contribute to a newspaper. For the first time, I tried to contribute for a long time, But I logged out. Although I didn't have a draft fee, I was very happy.

In many cases, we need to save the images in the image box to the database and read them from the database. Although the image boxes in VB support direct binding to databases to store images and read images, many merge operations cannot be used to solve the problem. As a result, many people use

Different CPUs have different sort of bytes. These sort of bytes refer to the order in which integers are stored in the memory. This is called the host order.There are two most common1. little endian: stores low-order bytes at the starting address2. Big endian: stores High-Order bytes at the starting address.Le little-EndianThe byte sequence that best fits people's
If you ever need to write a low-level network application, it could be necessary to handle the low-level data transmission O Ver The wire between the machines. This operation requires some sort of conversion of data from the native host operating system to the network format and VI Ce versa. This was because each of the one hat its own specific representation of data.When writing underlying low-level network applications, it may be necessary to handle low-level data that is routed between two de
