A byte is made up of several binary bits What about a character?

Actually, there is no contradiction.

The ASCII code is also 8 digits. The landlord here said that the ASCII only uses the first 7 digits, and the highest bit is pulled out to do the check bit. Therefore, the ASCII code can also be said to represent only 2 7 = 128 characters.

If you don't do the check digit, then you can represent an extra 128 characters.

The standard of a character can also be said to be a byte, which consists of 8 binary bits.

This should not be difficult to understand. Reference.

Byte is a unit of measurement used by computer information technology to measure storage capacity and transmission capacity.

1 byte is equal to 8 bits of binary.

A byte contains 8 binary bits.

Bytes are binary numbers.

According to the unit. A byte is usually 8 bits long. However, some older models of computer architecture use different lengths. To avoid confusion, in most international literature, words are used instead of bytes. in most computer systems.

, a byte is an 8-bit long unit of data, and most computers use a byte to represent a character, number, or other character.

A byte can also represent a series of binary bits. In some computer systems, 4 bytes represent a word, which is the unit in which a computer is able to process data efficiently while executing instructions. Some language descriptions require 2 bytes to represent a character, which is called a double-byte character set.

Some processors are capable of handling double-byte or single-byte instructions. Bytes are usually abbreviated as "b", while bits are usually abbreviated as lowercase "b", computer memory.

The size is usually expressed in bytes.

Between orders of magnitude:

The amount of information stored is a measure of the number of programs and data stored in the memory. Its main unit of measurement is bytes, and 1 byte is equal to 8 bits (b) binary. Binary digits:

Storing a one-digit binary number, i.e. 0 or 1, is the smallest unit of storage.

8 binary bits are one byte unit. An English letter (regardless of case and case) occupies one byte of space, and a Chinese character of Chinese occupies two bytes of space. English punctuation occupies one byte, and Chinese punctuation occupies two bytes.

A byte consists of 8 bit binary bits.

Binary is a system of numbers that is widely used in computing technology. Binary data is a number represented by two numbers, 0 and 1. Its cardinal number is 2, the carry rule is "every two into one", and the borrowing rule is "borrow one to become two", which was discovered by Leibniz, a German master of mathematical philosophy in the 18th century.

Current computer systems use basically binary systems, and data is stored in computers mainly in the form of complements. Binary in a computer is a very tiny switch, with "on" for 1 and "off" for 0.

The invention and application of the computer, which is known as one of the important symbols of the third scientific and technological revolution in the 20th century, because the digital computer can only recognize and process the data determined by '0''1' symbol string. The mode of operation is binary.

The 19th-century Irish logician George Bull's thought process on logical propositions was translated into pairs of symbols"0''.1''In some kind of algebraic calculus, binary is a base system that is a base of every 2 digits.

Because it uses only two number symbols, it is very simple and convenient and easy to implement electronically.

A byte is a unit of measurement used by computer information technology to measure storage capacity, and also represents data types and language characters in some computer programming languages.

A byte stores 8 unsigned digits with a range of 0-255 values. Like characters, byte-type variables only need to be stored in a single bit (8-bit) memory.

A byte is equivalent to a character, and the most commonly used byte is an octet byte, i.e., it consists of an octet of binary numbers.

In general, any binary n can be expressed as n=2j s; where j is a binary number, called a step code; If there are positive and negative signs, the positive and negative signs are called order symbols; s is a pure decimal, which is called a mantissa number; A number symbol, which refers to the symbol of the entire number of n.

Binary "00101000" can be converted directly to "28" in hexadecimal. Bytes are the basic storage units in the computer, according to the different length of the computer, the word has different digits, the word length of modern computers is generally 32 bits, that is, the number of bits of a word is 32.

A byte is an 8-bit unit of data, and a byte can represent 0 255 decimal data. For modern computers with a 32-bit word length, a word is equal to 4 bytes, and for early 16-bit computers, a word is equal to 2 bytes.

A byte is an 8-bit binary bit.

1b (byte) = 8 bits; Data storage is based on "bytes", and data transmission is mostly in "bits" (also known as "bits"), a bit represents a 0 or 1 (i.e., binary), and every 8 bits (b) form a byte (byte, abbreviated as b), which is the smallest level of information unit.

The formula 2 n is calculated from 0 to 2 n-1, because each digit is chosen between 0 and 1, so each additional digit must be multiplied by 2 possibilities.

2 bytes is 16 bits, which can represent 2 16 numbers, i.e. from 0 to 2 16-1

This is the operation of unsigned numbers, with a sign is a little more troublesome, containing the concept of original code, reverse code, and complement code, and it will not be finished for a while, and it is enough to know the unsigned.

Hexadecimal calculation 16*16*16*16=65536 is 64kb Calculation method: ffffh-0000h between the number of bytes converted to decimal is 65536, that is, 65536b1kb=1024b, so 65536 1024=64, the answer is 64kb

One byte is equal to an 8-bit base number.
