what is difference between one hot and binary encoding?
318170
Just one-hot encode a column if it only has a few values. In contrast, binary really shines when the cardinality of the column is higher — with the 50 US states, for example. Binary encoding creates fewer columns than one-hot encoding.

__________ bytes are required to encode 2000 bits of data. Explanation: Two bytes are required to encode 2000 (actually with 2 bytes you can encode up to and including 65,535.

An ASCII file is a binary file that stores ASCII codes. There are 128 different ASCII codes; this means that only 7 bits are needed to represent an ASCII character. So in any ASCII file, you're wasting 1/8 of the bits. ... Any of the 256-bit patterns can be used in any byte of a binary file.

The main difference between a byte and char data type is that byte is used to store raw binary data while other is used to store characters or text data. ... Another difference between byte and char in Java is that the size of the byte variable is 8 bit while the size of the char variable is 16 bit.

The two file types may look the same on the surface, but their internal structures are different. While both binary and text files contain data stored as a series of (bits (binary values of 1s and 0s), the bits in text files represent characters, while the bits in binary files represent custom data.

A 1-bit image contains just two tones, 0 Black and 255 White, so the intensity of each pixel can be specified by one binary digit, that is one bit. Examples are shown of typical 1-bit images created by program, graphic user interface, scanner, and camera.

The main difference between the two is in the way they encode the character and the number of bits that they use for each. ASCII originally used seven bits to encode each character. ... In contrast, Unicode uses a variable bit encoding program where you can choose between 32, 16, and 8-bit encodings.

Characters can have 1 to 6 bytes (some of them may be not required right now). UTF-32 each characters have 4 bytes a characters. UTF-16 uses 16 bits for each character and it represents only part of Unicode characters called BMP (for all practical purposes its enough).

1 byte may hold 1 character. For Example: Refer Ascii values for each character & convert into binary. This is how it works.

UTF-8, UTF-16, and UTF-32 are serialization formats — NOT Unicode. UTF-8 is an encoding, just like ASCII (more on encodings below), which is represented with bytes. The difference is that the UTF-8 encoding can represent every Unicode character, while the ASCII encoding can't. But they're both still bytes.

A byte is 8 bits (binary data). A byte array is an array of bytes. You could use a byte array to store a collection of binary data, for example, the contents of a file.

A binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number system. The binary code assigns a pattern of binary digits, also known as bits, to each character, instruction, etc.

In computers, encoding is the operation of placing a sequence of types (letters, numbers, punctuation, and certain symbols) into a specialized format for efficient transmission or computer memory. Decoding is the opposite process -- the conversion of an encoded format back into the original sequence of types.

The difference is that Java binaries compiled as x86 (32-bit) or x64 (64-bit) applications respectively. On a 64-bit Windows you can use either version, since x86 will run in WOW64 mode. ... For a Linux you should select appropriate type x86 for 32-bit OS, and x64 for 64-bit OS.

The default encoding is UTF-8. (in §6) JSON may be represented using UTF-8, UTF-16, or UTF-32. When JSON is written in UTF-8, JSON is 8bit compatible. When JSON is written in UTF-16 or UTF-32, the binary content-transfer-encoding must be used.

UTF-8 has an advantage where ASCII are most used characters, in that case most characters only need one byte. UTF-8 file containing only ASCII characters has the same encoding as an ASCII file, which means English text looks exactly the same in UTF-8 as it did in ASCII.

UTF-8 (8-bit Unicode Transformation Format) is a variable-width character encoding capable of encoding all 1,112,064 valid character code points in Unicode using one to four one-byte (8-bit) code units. The encoding is defined by the Unicode Standard, and was originally designed by Ken Thompson and Rob Pike.
