Why does Iot require 5 GB
When the fifth generation of communication technology (5 Gb) arrived in 2020, engineers expected it to be able to process 1000 times the mobile data of today's cellular systems. Some people think that it will also become a backbone network of the Internet of Things (IoT), connecting fixed and mobile devices (such as fixed vending machines and automobiles) and become part of the ne

Php makes it easy to process images using a gb library. The design idea of this class draws on jQuery and uses the concatenation method to operate images. for example, copy the code as follows: $imagenewUsaImage(array(filepathimage1.jpg). the design idea of image and image overwriting class is based on jQuery, use the concatenation method to operate images, such:
The code is as follows:
$ Image = new UsaImage (array ('filepath' => 'image1.jpg '));/
Today, I received an email from the Hotmail Member Service. It is said that there will be another change in Microsoft products.
In addition to increasing the size of the Hotmail inbox from 250 MB to 1 GB, Microsoft also launched the live series Windows Live Mail.
Windows Live Mail has the following features:

I used a popular method on the Internet to upgrade my Hotmail mailbox to 250 MB (of course, Ms has fixed this vulnerability and all users have now upgraded to MB ), I thought Verizon online had two backend referers recently, and ordered our fake MSN premium members to be associated with Verizon online accounts before March 31, January 20, otherwise, the system will lose its membership.
Take it for granted that the corresponding 2G ultra-large Hotmail mailbox should also be withdrawn, it is sa

Starting from Oracle Database 10 Gb, Oracle creates a scheduled task named GATHER_STATS_JOB by default after the Database is created, which is used to automatically collect CBO statistics.
This automatic task is enabled by default between-on the workday and all day on the weekend. Call DBMS_STATS.GATHER_DATABASE_STATS_JOB_PROC to collect statistics. This process first detects the missing and obsolete objects of statistics. Then, determine the priorit
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
In a file-processing system, it is easy to get the size out of some system's own method, the problem is that the size is often just a byte B.If you want to convert this byte number to a KB, MB, GB final rendering to the user, it involves the arithmetic operation of dividing and taking the remainder.Here's how:public static String getprintsize (long size) {///If the number of bytes is less than 1024, it is directly in B, otherwise except for 1024, the
Today in doing a network audit log when required to export the report, there is a mail attachment file size, the database is bytes byte number, the request to convert to KB display, use the following function, quite to the force, special to share.
function Sizeformat ($bytesize) {$i = 0;When the $bytesize is greater than 1024 bytes, start the loop, when the loop jumps to the 4th time;while (ABS ($bytesize) >=1024) {$bytesize = $bytesize/1024;$i + +;if ($i ==4) break;}The BYTES,KB,MB,
For example, when we refer to "data transfer speed" and "hard disk storage space", kilobytes represent 1000 (103), and when it comes to memory or CPU cache capacity, kilobytes represent 1024 (210) because they are stored here by byte-code address.
In practical applications, we often need to convert bytecode to KB, MB, GB, and so on, where we use JavaScript to convert bytecode:
The code is as follows
