Question 1: What is the relationship between bits and bytes? It should be said that a bit is the smallest unit of data in a computer. A bit is a single binary value, 0 or 1. Although computers can provide instruction test and operation bits, they usually store data and execute instructions in bytes of multiple bits. In most computer systems, a byte consists of eight bits. A bit value is represented in memory by the charging and discharging of a single capacitor at or below a certain level.

A bit is the smallest unit, and a byte is a bit and a unit.

What does the question bit mean? It is the unit of information, and the computer uses binary, for example, 0 1 001is a piece of information, where a number represents one bit, for example, 01is two bits, and 01is five bits.

Question 3: What are the units of bits, bytes and code streams? Their respective forms of expression? In computer science, a bit is the smallest unit of information, called a binary bit; Generally expressed by 0 and 1 A byte is called a byte, which consists of eight bits and is used to represent a character in a computer. Bits and bytes can be converted, and the conversion relationship is: 1Byte=8bit (or abbreviated as:1b = 8b); Abbreviations are generally used in practical applications, that is, 1bit is abbreviated as 1b (note that it is lowercase English letter b) and 1Byte is abbreviated as 1B (note that it is uppercase English letter b).

Data rate refers to the data stream used by video files per unit time, also known as code rate, which is the most important part of image quality control in video coding. At the same resolution, the larger the bit stream of a video file, the smaller the compression ratio and the better the picture quality.

Video bit rate and code stream are just two names of the same problem. For example, MPEG2-2 video files usually contain not only video information, but also audio information, and audio also has its own bit rate. This is a file composed of audio and video information, and the code stream of this file is the sum of its audio and video code streams.

There are many translations of the word bit rate, such as code rate, which indicates how many bits are needed per second to represent encoded (compressed) audio data. One bit is the smallest unit in binary, either 0 or 1. The relationship between bit rate and audio-video compression is simply that the higher the bit rate, the better the audio-video quality, but the larger the encoded file; If the bit rate is small, the opposite is true.

For example, audio and video are encoded at 500Kbps.

Where 1KB/s = 1024 * 8bp,

B is a drill.

S is the second.

P is every (every)

Therefore, encoding at 500Kbps means that the encoded audio and video data needs to be represented at 500k bits per second.

Specifically, for audio, the code stream = sampling rate × number of bits × channel, so for common CD format audio, the code stream is: 44100×16× 2 =1.41mbit/sec, that is, a one-second file. The common 160Kbps Mp3 file needs160k/1020/8 = 0.01953125m per second, which is nearly10 times.

Question 4: What do bytes, characters, bits and bits mean? Byte: Byte is a unit for transmitting information through the network (or storing information in hard disk or memory).

Byte is a unit of measurement used by computer information technology to measure storage capacity and transmission capacity. 1 byte equals 8-bit binary.

In ASCII code, an English letter (regardless of case) occupies one byte and a Chinese character occupies two bytes.

Symbol: English punctuation occupies one byte and Chinese punctuation occupies two bytes. For example, the English period "."accounts for 1 byte, and the Chinese period "."has a size of 2 bytes.

As a digital unit in a computer, a sequence of binary numbers is usually an 8-bit binary number. For example, ASCII code is a byte, and the conversion of this unit is:

1 kilobyte (TB, terabyte) = 1024 gigabyte (2 to the 40th power)

( 1TB= 1024GB)

1 gigabyte (GB, gigabyte) = 1024 megabyte (2 to the 30th power).

( 1GB= 1024MB)

1 megabyte (MB, megabyte) = 1024 kilobyte (2 to the 20th power byte)

( 1MB= 1024KB)

1 kilobyte (KB, kilobyte) = 1024 bytes (65438+2 to the power of 00 bytes) (1KB= 1024B).

1 byte) = 8 bits.

The larger units include PB(PB, 1PB= 1024TB), EB(EB, 1EB= 1024PB) and ZB(Zettabyte,1zb =/kloc-0).

Character; Role; letter

Characters are abstract entities that can be represented by many different character patterns or code pages. For example, Unicode UTF- 16 encoding represents characters as 16 bit integer sequences, while Unicode UTF-8 encoding represents the same characters as 8 bit byte sequences. The common * * * language runtime uses Unicode UTF- 16(Unicode conversion format, 16 bit encoding form) to represent characters.

Bits in a computer

In the binary number system, every 0 or 1 is a bit, and one bit is the smallest unit of data storage. In which 8 bits are called a byte. The number of CPU bits in a computer refers to the maximum number of bits that the CPU can handle at a time. For example, the CPU of a 32-bit computer can process up to 32-bit data at a time.

1) Computer terminology is a kind of information unit, which is transliterated from English BIT. One bit of a binary number contains one bit of information, for example, the binary number 0 10 1 is four bits.

Question 5: Are bits bits or bytes? Bit means bit, bit

Bytes are bytes.

Question 6: What is a bit in a digital signal? It is the abbreviation of English binary number and the smallest unit of binary. A binary system is called a bit and has only two states: 0 and 1.

The information content of n-bit data can be expressed as the n power of 2. For example, a byte of a computer is 8-bit binary, the decimal data range is 0~255, and there are 256 combinations of * *.

Question 7: What is the relationship between bits and bits? In computer science, a bit is the smallest unit of information, called a binary bit. Generally expressed by 0 and 1 Byte is called byte, which consists of eight bits (8bit) to form a byte (1Byte), which is used to represent a character in a computer. Bits and bytes can be converted, and the conversion relationship is: 1Byte=8bit (or abbreviated as:1b = 8b); Abbreviations are generally used in practical applications, that is, 1bit is abbreviated as 1b (note that it is lowercase English letter b) and 1Byte is abbreviated as 1B (note that it is uppercase English letter b).

Resolution)-A measure of the sharpness or density of an image. For example, the resolution represents dots per inch (dpi) displayed vertically and horizontally.

Question 8: What is the abbreviation of BIT in computer field? Two concepts of information unit (bit);

1) Computer terminology is a kind of information unit, which is transliterated from English BIT. One bit of a binary number contains one bit of information, for example, the binary number 0 10 1 is four bits.

2) A bit in a binary number is the smallest unit of information. In digital acoustics, audio signals are represented by electric pulses, "1" represents pulses, and "0" represents pulse intervals. If the information of each point on the waveform is represented by a four-bit code, it is called four bits. The higher the number of bits, the more accurate the expression of analog signals and the stronger the ability to restore audio signals.

Bits in a computer

In the binary number system, every 0 or 1 is a bit, and one bit is the smallest unit of data storage. In which 8 bits are called a byte. The number of CPU bits in a computer refers to the maximum number of bits that the CPU can handle at a time. For example, the CPU of a 32-bit computer can process up to 32-bit data at a time.

Bit, the abbreviation of binary number, is a term put forward by mathematician John Wilde Tukey (it may have been put forward by 1946, but some data say it was put forward by 1943). This term was officially used for the first time in the famous Shannon's Theory of Information, that is, the Mathematical Theory of Communication, on page 1.

Suppose an event occurs in the form of A or B, and the probability of A and B is equal, both of which are 0.5. You can use a binary to represent one of A or B ... For example:

1) binary can be used to express simple affirmative/negative judgment.

2) a switch with two states (such as a light switch),

3) On and off of the triode,

4) Whether there is voltage on the wire, or

5) The logic of snapshot is Yes/No, etc.

Because the length will change after being converted into binary, the information of one bit in different number systems is not always a binary, and its corresponding relationship is logarithmic, such as one bit in octal, which is equivalent to three binaries. In addition to binary, there are octal, decimal and hexadecimal commonly used in computers.

Question 9: What is bit? How is it expressed and passed on? The Chinese name of bit is bit, transliterated as "bit", which is the smallest unit to describe the amount of computer data.

In the binary number system, every 0 or 1 is a bit.

Unit conversion

1 byte = 8 bits

1Kb= 1024byte (bytes) =8* 1024bit.

1Mb= 1024kb

1Gb= 1024Mb

1Tb= 1024Gb

One bit (abbreviation of binary bit) is the smallest unit of data in a computer. A bit has a value, 0 or 1. When a computer stores data and executes instructions, it takes a group of bits as a unit, usually called bytes. In most computer systems, a byte contains eight bits. Half a byte (four bits) is called a nibble. In some systems, octets are used to replace bytes with eight-bit memory cells, while in other systems, four bytes or octets constitute a 32-bit word. In these systems, the length of an instruction is usually expressed as a whole word (32 bits long) or a half word (16 bits long). In telecommunication transmission, the bit rate is the number of bits transmitted in a given time, usually the unit time is seconds.
