0. Reply content: If you use Node. js, can you use it if you don't need npm to pull dozens of hundreds of megabytes of data? The python installation package looks like a dozen mb. It was just yesterday that node was used. During the installation, it was only 5 MB in size and thought it was lightweight. When you started writing code, didn't you always download various packages from npm? In a project, there are more than 10 MB of npm packages, not a s

, because the network transmission will have loss, while the download speed also to the other server can provide bandwidth, so 4M broadband, download speed has 400kb/s is normal.So boss Lee's 4M broadband upload only 50kb/s normal? How much should the theory be?Similarly, the theoretical speed of the first calculation of the theoretical velocity is 512kb/s, and previously said that ADSL broadband upload speed is the download speed of 1/8, so 512kb/s/8=64kb/s, in addition to network transmission
Cacti self-brought traffic monitoring threshold template for "interface–traffic", can only monitor bytes, after adding thresholds, alarm traffic information in bytes units, viewing is unfriendly, you can convert Btyes to MB units by the following methods.1, add the Traffic conversion template, open the Control Panel management function, find cdefs:2, click Add in the top right corner of the page, the following page appears:This function is named as: Turn Bytes to Mbits, after saving, we create a

bigfile tablespace is a tablespace with a single, but potentially very large (up to 4G blocks) data file. Traditional Smallfile tablespaces, in contrast, can contain multiple data files, and the files cannot be as large. The benefits of Bigfile tablespaces is the following: A bigfile tablespace with 8K blocks can contain a + terabyte data file. A bigfile tablespace with 32K blocks can contain a, terabyte
Yte is a unit of measurement of computer information technology used to measure storage capacity and transmission capacity, with 1 bytes equal to 8-bit binary. At the moment we often calculate the smallest unit of storage space (in fact there is a smaller bit,1 byte=8 bit).However, from the hard disk or called storage space, we use the smallest unit is KB (kilobyte), the size of 2 10 bytes, and byte conversion is: 1kb=1024byteThe conversion of the future is basically based on 2 of the 10-time in
Storage capacity: The maximum number of data that can be stored on the storage device, typically in kilobytes (KB kilobyte), megabytes (MB megabyte), gigabytes (GB, gigabyte), Byte (TB, terabyte), and Pb (Petabyte), EB ( Exabyte), etc. to measure. 1kb=2 (b=1024b); The number in parentheses is the index of 2 (that is, how many times) 1mb=2 (a) kb=1024kb=2 (a) B; 1gb=2 (mb=1024mb=2) B. 1tb=2 (a) gb=1024gb
Byte: bytes are units that transmit information over the network (or store information in hard disks or in memory).Bytes are a unit of measurement used by computer information technology to measure storage capacity and transmission capacity, with 1 bytes equal to 8-bit binary.In ASCII, an English letter (not case) occupies a single byte of space, and a Chinese character occupies two bytes of space.Symbol: English punctuation occupies one byte, Chinese punctuation is two bytes. Example: "." 1 byt
