A codepage maps a value to a character, very much like the code decoder rings some people may have had as children. It gives computers a way to interpret text data as binary data.

Can you create a sentence with byte?
yes because each byte represents one letter.
How many bits are in extended ASCII byte?
An extended ASCII byte (like all bytes) contains 8 bits, or binary digits.
What has a common computer keyboard to do with ascii?
Ascii is simply an encoding scheme. It represents text by assigning a code to each particular character.
Is bytes a vector or a scalar quantity?
A byte is 8 bits. They can represent all of the ASCII characters and any value between 0 and 255. It could be both. It just represents a value.
What Requires one byte of storage?
8 digits of binary code (either 0s or 1s) for instance 00101001 each digit takes up one bit, there are 8 bits in a byte. Usually, a byte holds 1 character, either a letter or #
Why does ascii go 0-255?
1 byte is made up of 8 bits.In Binary 8 bits have a value of 0-255, therefore any character in ASCII will only take up a physical space of 1 byte.
In computing what does a single byte represent?
A single byte represents 8 bits.
How much data is on 1 byte of ram?
One byte of RAM can hold up to one byte of data. This is equivalent to one 8-bit (ASCII) character, such as a keyboard letter, number, or symbol.
What is 1 byte?
It is a collection of eight bits which represent one character. Each bit can have the value of 0 or 1, zero or one. A byte has 256 possible combinations of 0's and 1's. In most programming languages and applications, these combinations are assigned values or functions. In ASCII, 00101010 (42 in decimal) is the * symbol. Number 189,(10111101 in ASCII) is ½ and 241 is ñ. There are other uses and definitions of a byte, including how many bits are in one.
What does msb represents in a byte?
MSB represents Most Significant Bit.
What does each byte represents?
Each byte represents a number. What that number means, will depend on where abouts it is, in a memory location or program. For example. In the graphics area of memory, the number will determine what color the pixel should be for that location. There will be a byte for every pixel. A pair of bytes will represent where the computer should look in the memory to retreive another number. A single byte will represent a command, when executed by the CPU. A program is operated on, one byte at a time in sequence, unless the operation code (another byte) tells it to jump to another part of the program or stop. A CPU has a look up table, where each number (represented by a byte) will have an operation. This operation could be, to just add 1 to the number in the present registry.
How many bit are used to encode an ASCII character?
All ASCII character sets have exactly 128 characters, thus only 7-bits are required to represent each character as an integer in the range 0 to 127 (0x00 to 0x7F). If additional bits are available (most systems use at least an 8-bit byte), all the high-order bits must be zeroed. ANSI is similar to ASCII but uses 8-bit encodings rather than 7-bit encodings. If bit-7 (the high-order bit of an 8-bit byte) is not set (0), the 8-bit encoding typically represents one of the 128 standard ASCII character codes (0-127). If set (1), it represents a character from the extended ASCII character set (128-255). To ensure correct interpretation of the encodings, most ANSI code pages are standardised to include the standard ASCII character set, however the extended character set depends upon which ANSI code page was active during encoding and the same code page must be used during decoding. ANSI typically caters for US/UK-English characters (using ASCII) along with foreign language support, mostly European (Spanish, German, French, Italian). Languages which require more characters than can be provided by ANSI alone must use a multi-byte encoding, such as fixed-width UNICODE or variable-width UTF-8. However, these encodings are standardised such that the first 128 characters (the standard ASCII character set) have the same 7-bit representation (with all high-order bits zeroed).
