External SCSI hard drive has many advantages, such:
1. If you do not need a hard disk, you can turn off the power to reduce unnecessary work on the hard disk.
2. Easy to disassemble and install. You do not nee

In order to reflect your beautiful scenery, you need to minimize the area of your land. To enclose a polygon with at least three points, the vertex of the polygon is a wooden pile, and the land circled is the land inside the polygon. [Input format] an integer n in the first line, i

The SCSI interface occupies an unattainable position in the world when it comes to the peripherals of computers, especially the interfaces of storage devices. This not only represents its advanced technology and performance, it also implies that it has a high price.The meaning of SCSI is the small computer system interface (Small Computer system Interface), which was first developed in the late 1970s.

The Fgetcsv () function reads a row from the file pointer and resolves the CSV field.
Similar to Fgets (), the difference is that fgetcsv () parses a read-in row and finds a field in CSV format, and then returns an array containing those fields.
Fgetcsv () returns FALSE when an error occurs, including when the file ends.
Note: from PHP 4.3.5, the operation of Fgetcsv () is binary safe.

Introduction of SCSI Card
The English of SCSI is all called "Small Computer system Interface", Chinese name "Small computer system interface". It is a peripheral interface, in the server is mainly used by the hard disk, in addition, there are cd/dvd-rom, CD-R/RW, scanners, tape drives, etc. also have the use of this interface. In fact, SCSI is not a new type of

The netraid controller uses its SCSI channel to combine multiple disks into a disk array. Simply put, an array is a disk system composed of multiple disks that work in parallel. Note that hot backup disks cannot be added to the array. Array spannin
