What do bits, bytes, and addresses all mean

A bit is the smallest unit of data in a computer.

Computers use binary systems to represent and store data, and 1 bit is 1 binary number.

0 or 1; Bytes are also units of data, and the conversion formula with bits is 1 byte = 8 bits;

An address is a method of encoding memory space, and when data is saved to memory, it can quickly find the stored data according to its address encoding.

To use an analogy, if you buy a one-bedroom apartment in Beijing, this can be regarded as a bit because you live in one person;

Later, I bought a three-bedroom apartment, which can be regarded as bytes, because it can live for a family;

These two houses are different in size, but they will give you the house number when you apply for the real estate certificate (this is the address).

The relationship between bits and bytes is that 8 bits make up a byte.

Byte: The unit in which data is stored in a computer.

Bit: Also known as a "bit", the smallest unit of data stored in a computer, because the data is stored in binary form in the computer, so each bit is represented by "0" or "1".

Byte-to-bit relationship: 1byte = 8 bits.

Bytes represent codes

1. ASCII code.

An English letter (case-insensitive) occupies one byte of space. A sequence of binary numbers, which is used in a computer as a unit of numbers, is generally an 8-bit binary number. Converted to decimal system, the minimum value is 128 and the maximum value is 127.

2. UTF-8 encoding.

One English character is equal to one byte, and one Chinese character (including traditional Chinese) is equal to three bytes. Chinese punctuation takes up three bytes, and English punctuation takes up one byte.

3. Unicode encoding.

One English is equal to two bytes, and one Chinese (including traditional) is equal to two bytes. Chinese punctuation takes up two bytes, and English punctuation takes up two bytes.

The relationship between bits, bytes, and words is: 1 bit = 1 bit; 1 word = 2 bytes; 1 byte = 8 bits; 1 word = 16 bits.

A byte is a unit of binary data. 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.

1. Bits. A bit is the smallest unit of computer storage, abbreviated as b, also known as a bit, and computers use binary 0s and 1s to represent data, with a 0 or 1 representing a digit. The number of bits usually refers to the size of data that can be processed in a computer at one time;

2. Bytes. Byte, English byte, is a unit of measurement used by computers to measure storage capacity, usually one byte is equal to eight digits, bytes also represent data types and language characters in some computer programming languages, in modern computers, a byte is equal to eight digits;

3. Words. A word is a term that denotes a computer's natural data unit, and in a particular computer, a word is a fixed-length set of bits that it uses to process a transaction at once, and in modern computers, a word is equal to two bytes.

A byte is a unit of binary data. 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", and the size of computer memory is usually expressed in bytes.

Differences: 1. Storage.

The memory in the microcontroller is usually organized in bytes (8 bits), that is, each byte has an address, and any byte in the memory can be accessed through the "byte" address, which is the most common form. The problem that starts with "sfr" is the definition of a byte address, which is equivalent to giving another alias to the specified address, through which the byte storage unit can be accessed in the future.

2. Operational object.

For applications such as switch control, the MCS-51 microcontroller integrates a one-bit processor inside, and the operating object of this processor is a single bit bit (not byte), in order to store the bits, a bit memory area is superimposed on the memory in the form of original bytes, and an address is given for each bit, so that the bit address space is constituted.

3. Storage unit address.

Because it is an overlay bit memory, it is formally represented as follows: some memory cells in the memory can be accessed either through a byte address or through a bit address (specifically to access a bit in the byte).

There is a point in the byte address of these byte storage units that are superimposed in MCS-51 microcontrollers, that is, the lowest bit of the byte address is either 0 in hexadecimal or 8 in hexadecimal, and 00h in the bit address corresponds to the d0 bit in byte 20h.

The relationship between bits, bytes, and words is: 1 word = 2 bytes, 1 byte = 8 bits, and 1 word = 16 bits.

Bit (bit), data storage is in "byte" (byte) as the unit, data transmission is mostly in "bit" (bit, also known as "bit") as a unit, a bit represents a 0 or 1 (that is, binary), every 8 bits (bit, abbreviated as b) to form a byte (byte, abbreviated as b), is the smallest level of information unit, is a unit of measurement used by computer information technology to measure storage capacity.

The conversion relationship between the other units is as follows:

1 byte（b）= 8 bit。

1 kilo byte（kb） =1024b。

1 mega byte（mb） =1024 kb。

1 giga byte （gb）= 1024 mb。

1 tera byte（tb）= 1024 gb。

1 peta byte（pb） =1024 tb。

8 bits = 1 byte, and "bits" are the smallest units of data storage. Bytes are also called bytes, 1byte = 8 bits (bits), 1024byte (bytes) = 1KB, 1024KB = 1MB, 1024MB = 1GB, 1024GB = 1TB.

Computer Tips:

1. The computer can change the boot password, click "Start" in the lower left corner of the win10 system, "Account", "login option", "password", "change" option, and change the password. If you want to clear the computer usage history, you can enter the "settings" interface of win10 and click "privacy" to clear the computer usage history.

2. The computer can speed up the boot speed, you can open the "Task Manager" of win10, click the "Start" tab, and set the program that does not need to start automatically to "Disable".

In ASCII codes, an English letter (regardless of case and case) occupies one byte of space, and a Chinese character occupies two bytes of space. In UTF-8 encoding, one English character is equal to one byte, and one Chinese (including traditional Chinese) is equal to three bytes. In Unicode encoding, one English is equal to two bytes, and one Chinese (including traditional) is equal to two bytes.

Bytes are denoted as bytes, bits are denoted as bits, and 1 byte = 8 bits.

The smallest unit of data storage is bits, but computers generally process data in bytes.
