In computer science, a bit is the smallest unit of information, called a binary bit; It is generally denoted by 0 and 1. A byte is called a byte, and it is composed of 8 bits (8 bits) to form a byte (1byte), which is used to represent a character in a computer. The conversion between bit and byte can be performed, and the conversion relationship is as follows:
1byte=8bit (or abbreviation: 1b=8b); In practical applications, abbreviations are generally used, 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). In computer networks or network operators, in general, the unit of broadband rate is expressed in bps (or b s); bps stands for bits per second, which means how many bits of information are transmitted per second, and is an abbreviation for bit per second.
In practice, 1M bandwidth means 1Mbps (is megabits per second Mbps, not megabytes per second). It is recommended that users remember the following conversion formula: 1b=8b 1b s=8b s (or 1bps=8bps) 1kb=1024b 1kb s=1024b s 1mb=1024kb s=1024kb s Specification tip:
In the actual writing specification, b should mean byte (byte) and b should mean bit (bit), but in the actual writing of ordinary times, some bit and byte are mixed into b, such as mb s and mb s are mixed into mb s, which leads to people making mistakes due to the confusion of units in actual calculations.
-
kbps which is the speed and the bytes transmitted per second are k bytes of seconds.
-
Small dec small is basically correct. This speed is very slow, even the standard of broadband is very reluctant, k byte second speed, can only be regarded as a medium to low grade, now 2MB of broadband, the normal speed is about 1MB, you see you are still a lot worse, hurry up and change the telecom!

Network speed reference value: The units of capacity from largest to smallest are: bytes TB (T), GB (G), MB (G), KB, bytes (B). MB S and KB S refer to the speed of the Internet in seconds.
1TB = 1024GB, 1GB = 1024MB, 1MB = 1024KB, 1KB = 1024 bytes, and so on.
Data communication is based on "character bits", that is, bits (lowercase b), and the relationship between the two is 1byte = 8 bits. The network speed mentioned in the telecommunication service is 1m, 2m, 3m, 4m, etc., which is calculated in the unit of data communication.

bits per second, kilobits per second, megabits per second.
1. No slag bits per second (bps): 1 bps represents the amount of data transmitted by 1 bit per second.
2. Kilobits per second (kbps): 1kbps represents the amount of data transmitted 1000 bits per second.
3. Megabits per second (Mbps): 1 Mbps represents the amount of data transmitted at 1,000,000 bits per second.
As network transmission rates continue to increase, higher units have emerged: gigabits per second (Gbps): 1 Gbps represents the amount of data transferred at 1,000,000,000 bits per second.

1. B, KB, MB, GB are all units of measurement of computers, and MB S and KB S are talking about network speed. The GB is the largest of these types.
2. Usually say one trillion, four trillion refers to 1m (trillion), 4m (trillion). If it is bandwidth, it is 1 Mbit, 4 Mbit. If it is a computing size, it is 1mbyte, 4mbyte.
3. B is the abbreviation of byte (byte), which is a unit of measurement used by computer information technology to measure storage capacity, and is a binary digital string processed as a unit, which is a small unit of information. The most commonly used byte is an octet byte, i.e., it contains an eight-bit binary number.
1. There are many fields of bandwidth applications, which can be used to identify the data transmission capacity of signal transmission, the amount of data passing through the link per unit time, and the display ability of the display.
1. In the analog signal system, it is also called bandwidth, which refers to the amount of data that can be transmitted at a fixed time, that is, the ability to transmit data in the transmission pipeline. It is usually expressed in cycles per second or hertz (Hz).
2. In digital devices, bandwidth refers to the amount of data that can pass through a link per unit of time. It is usually expressed in bps, which is the number of bits that can be transmitted per second.
2. Byte is a unit of measurement used by computer information technology to measure storage capacity, and a binary number string is processed as a unit, which is a small unit of information. The most commonly used byte is an octet byte, i.e., it contains an eight-bit binary number.

KB is faster, a megabyte is a GB, and so on.

bit(b) is a bit, byte(b) is a byte, and a byte is composed of 8 bits, that is, 1byte = is thousand, 1kb = 1024b, and 1kb = is trillion (million).kbs is a kilobyte second. There is an equivalence relationship between these units and they can be converted to each other.
1 Mbps represents 1,048,576 bits per second (1MB=1000KB=1024*1024 bits), that is, 1,048,576 8 = 131,072 bytes = 128 KB= per second, so the formula for converting x Mbps to every MB per second is: x 8.
4 megabytes is 4 Mbps, which is 4,194,304 bits per second.

Network speed is actually the network bandwidth, which indicates the data transmission rate of the channel during digital communication, and the unit is bits s, which indicates the number of bits (bits) of binary data transmitted per second. b s and b s are not the same, the former is a bit of a small character b, and the latter is byte (byte), 1 byte = 8 bits. Generally speaking, the speed of 1m means that the speed of ** can reach 128kb s
-
It's the same as a computer storage unit.
B: Bytes KB: Kilobytes 1024B=1KB MB: Megabytes 1024KB=1MB GB: Gigabytes 1024MB=1GB TB: Megabytes 1024GB=1TB
-
Storage unit Two Chinese characters = one byte B: Byte KB: Kilobyte 1024b = 1kb MB:
MB 1024KB=1MB GB: Gigabytes 1024MB=1GB TB: MBytes 1024GB=1TB
-
Actually, it's not kb s but kb s (note the case) uppercase b refers to byte, byte; Lowercase b refers to bit, and a byte occupies 8 bits, which means that 1byte = 8bit (1b = 8b) kb s (sometimes written as kbps) is kilo-bype second, which indicates how many kilobytes per second.
The unit they use for telecom or network is Mbps, and 4 trillion is 4Mbps, which is equal to. Therefore, the theoretical limit speed of 4 trillion ports is one second, that is, 512kb per second, and this speed cannot be reached due to line loss and delay.
-
I'm talking about 1 trillion 100 kbs, 2 trillion 200 kbs, 3 trillion 300 kbs, and so on.
-
What is said here is more complete, you can take a look.
-
4m divided by 8 is theoretically 512kb s
That's how many kilobytes and bits are per second
