1, first, K and K case is no difference (kilo), M and M is the same 2, B is a bit, that is, a bit, B is a byte, that is, Byte, 8bit =1byte, a letter a byte, a man two bytes 3, 1024B =1KB,1024KB=1MB,1024MB=1GB,1024GB=1TB Answer 1: Why 200M Broadband in the network transmission speed also did not reach 200M. Because b in 200Mbps is lowercase, equivalent to 25MB PS Q-2:KB,MB,GB and Kib,mib,gib are these a meaning? No, of which

1m equals how many kb Brain storage Conversion is 1024 to 1 units, that is to say 1m=1024k, 1024m=1g,1024g=1kg, but computer hardware is calculated in 1000 units, that is, the capacity of storage devices such as hard disk (such as 80G hard disk) =8000m, There is a storage error between the hardware and the software. Normally, the M unit reads "Mega" sign bit MB abbreviation m, and its conversion units are: 1MB=1024KB we are short for 1m=1024kThe un

Relationship between Kb/KB and Kbps/KBps Recently, a problem occurred in the lab, and the lab was pulled to join us .. Old wet C has re-allocated broadband for the lab and removed a lot of restrictions, so the lab has been able to threaten the whole building's Network (if someone downloading it maliciously ).. In order to avoid making trouble for the old wet guys, we found a unit to be noted during configur

Conversion Formula8bit (bit) =1byte (bytes)1024Byte (bytes) =1kb1024kb=1mb1024mb=1gb1024gb=1tbThe capacity is uppercase B and the speed of transmission is lowercase bBPS is the abbreviation for bits per second, which indicates bits per second.BPS is the abbreviation for bity per second, which represents bytes per second.This p can also be written/, S is the abbreviation of the second, so bps = b/SKB and KB differences: The information in the computer

We commonly have kb/s and kb/s two species of 1,kb/s, also known as Kbps. The lowercase b In this case is the abbreviation for bit (bit), which is the meaning of bit. A bit is the binary 0 or 1. The General representative transmission Unit, p is the/number, S is the second. BPS is b/s= bits per second KB is gigabit MB

The size of the compressed image is smaller than the specified Kb, and the size of the compressed image is smaller than kb. This function is available for PS and QQ images. The image size is compressed to smaller than the specified kb. So far, I have also come to shanzhai to control the image size. The usual solution is to control the resolution and quality. Assu

I talked to my colleague today. KiB kb kb KiB The meaning of these units and their differences, their own on-line also check the information, summarized as follows:Ki and K are just mathematical unitsKi = 1024K = 1000There's no connection between the two.B and B represent physical storage unitsB = byte is a byteb = bit is a bitsKnowing the fundamentals of the computer, the relationship between the two is: 1

We know whether the network file or broadband bandwidth or mobile Internet traffic, its units are m (trillion), a lot of friends mobile phone general selection of 5 yuan packet 30M flow, the general Internet chat QQ, browsing some mobile Web pages are enough. So there are a lot of rookie friends often ask small 1M equals how many KB or 1M how big? The so-called KB MB GB is the unit of memory size They all

Read-only disc memory CD-ROM is the normal CD that we often use. CD-ROM discs can be used to cross storage of large volumes of text, sound, graphics and images and other media digital information for quick retrieval, so the CD-ROM drive has become a standard configuration of multimedia computers.

Exposure to computers all day, inevitably with a variety of measurement units to deal with, especially data, but you know bit, Byte, KB, GB, TB and so on all means how much data? Have you heard of EB, ZB, YB? Bit (bit) is the initials of binary digit, the unit that measures information, and the smallest unit that represents the amount of content, only 0 or 12 binary states. 8 bits make up a byte (byte), can hold an English character, and a Chinese ch

After the stm32 USB program changes bulk EP to a dual-buffer mechanism, the speed of receiving out data is increased from kb/s.When I tested my own USB driver the day before yesterday, I found that the out transmission rate from the host to the stm32 (from the host to the device) was only kb/s, and it was truly dizzy. After research, we found that it is the relationship between the pipe maxtransfersize para

(Below ArticleNote the case sensitivity between B and B during reading.) 1. Differences between kb and KB: The information in the computer is represented by binary 0 and 1. Each 0 or 1 is called a single bit, which is expressed by lowercase B, that is, bit. uppercase B indicates byte, that is, byte. one byte = eight bits, that is, 1B = 8B; the upper-case k indicates the meaning of a thousand, that is, a t

Calculates the size of the folder, including subfolders, formatting the output folder size, number of files, and the number of subfolders.

In the computer newspaper, the Dutch bank's 20 data centers have about 7PB of disk and more than 20PB of tape storage, and the annual growth of 50%~70% reserves, So want to see how much PB, calculate 27pb about 400,000 80 of the hard disk size. 1Byte = 8 Bit (0,1) 1 KB = 1,024 Bytes (size of a shortcut) 1 MB = 1,024 KB = 1,048,576 Bytes (size of a floppy disk) 1 GB = 1,024 MB = 1,048,576

A string of about KB, which is a number + delimiter. Because it is submitted by the user, check whether it is legal. Here, I use preg_match_all + Regular Expression to detect strings. When strings are short, they can be detected. No problem occurs. When strings exceed kb, nginx will be 502. I also found the problem... A string of about KB, which is a number + del

The size of the php statistics file, which is measured in GB, MB, KB, and B. Use the filesize () function command to calculate the file size. the value 1 must be an output of GB, MB, KB, and B. 2. the order of magnitude must be greater than 1 and less than 1024, and two decimal places must be retained. use the filesize () function command to calculate the file size. requirements: 1, it is an output in GB, M

Recently, When I encountered a problem in the integrated project, I did not pay attention to it at first, but then I found out that it was myProgramI can't burn it into the chip, after checking the manual, I found that the flash of the New Tang cortex-m051 is only 8 KB, after my program is compiled, the binfile actually has 16 KB, my program has only over 1300 lines of comments. How can it be so big? I
