We often hear about who drives the broadband is 4M or 10M or 20M and so on. So this is the same as what we call "how much MB/s" and "How many kb/s"?In fact, this is not a concept.Broadband operators in the broadband, such as 4M, is actually said 4M bit/s, that is, bits per second.And what we call the download speed is b/s, that is, bytes per second.Remember two relationships: 1b/s = 8 b/s;1 M =1024k.So 1M of fiber, that is 1M b/s =1 M/8 b/S =0.125 MB/

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. Assuming that the size of the last compression is kb, the image quality is as high as possible while ensuring that the size is not greater than kb.The higher the image quali

Decomposition time limit for the number:MS | Memory limit:65535 KB Difficulty:1 Describe Your task is to find a minimum positive integer q so that the product of the Q's number of members equals N. Input Up to 450 sets of test data. The data ends with EOF. Enter an integer N (0≤n≤400). Output Output Q, if Q does not exist then output −1. Sample

Recently solved a problem-reducing memory usage. However, this method can only be used in WINXP and Win2k, without displaying that the main form is always running.ProgramBest. In the past, the program used 11 MB of memory. I used the dynamic window creation method to reduce the size by less than 100 kb. After applying this method, the memory usage was only 496 kb. Put the following process in a timer and ex

such as PS,QQ images have this feature, compress the image size below the specified KB.I also come to the cottage, so far, to control the size of the picture, the usual solution through the resolution and quality control.Assuming that the size of the last compression is 100kb, then the picture quality is as high as possible without a guarantee of greater than 100KB. the higher the image quality, the larger the image occupies . But the size and quality of the relationship, there is no fixed formu

. Scientific verification, people's psychology is inevitable comparison, but too much comparison with others, it is easy to make themselves out of balance. Therefore, focus less on others and compete with yourself: set a goal, and then assess whether you have achieved the preset goal or plan to see if you are making more progress today than yesterday, and whether tomorrow will be more advanced than today. 4.

We often use code such as Javascript:void (0), so what does javascript:void (0) mean in JavaScript?The key in Javascript:void (0) is the Void keyword, which is a very important keyword in JavaScript, which specifies that an expression is evaluated but does not return a value.The syntax format is as follows:href= "javascript:void (0)"> Click here Nothing will happen a >void (0) evaluates to 0 when the user links, but does not have any effect on Javascript.In the following example, a warning messa

BYTE (byte) is B: A byte is made up of 8-bit binary digits (1 byte = 8 bit). Byte is the most common base unit in the information store. An English letter (case-insensitive) occupies a byte of space, a Chinese character occupies two bytes of space.Symbol: English punctuation 2 is a byte, Chinese punctuation is two bytes. A binary numeric sequence, as a digital unit in a computer, typically a 8-bit binary number,If an ASCII code is a byte, the conversion of such units is: 1000 gigabyte (tb,kil

Idle boredom comes to the end: bit: We often say bit, what is the bit. bit is the smallest unit of data in the legendary computer: it's 0 or 1, and the storage in the computer's memory is 01 of these two things. Well, yes, that's the way it is. bytes: English words: (byte), byte is the basic unit of measurement of storage space, so the problem is, since it is the measurement unit of storage space, what is the storage of it, you just have to remember these two words on OK: 1byte deposit 1 E
