the file is located. Therefore, the size of each file is also related to inode/block.The region of the inode record block number is defined as 12 Direct, 1 indirect, 1 double indirect, and 1 three indirect.
What does it mean? These 12 blocks direct to the inode are directly used to record file data. One indirect point is that the blocks direct to the inode are not directly used to store file data, on the contrary, other block numbers are stored in this block, and the blocks corresponding to the
. subnet division and mask settingsSubnet division is achieved by dividing the original network into several subnets by using several host locations of IP addresses as subnet addresses. When dividing subnets, The subnet address is borrowedAs the number of hosts increases, the number of subnets increases, and the number of available hosts in each subnet decreases. Take the class C network as an example. The original 8-bit host space is 2 ^ 8, that is, 256

to three minutes to transmit a MB file at a speed of KB (different from the wired network, because there is interference uncertainty in the wireless access network transmission, so the time cannot be accurate ).

minutes to transfer a 1 GB file. For games with more than several gigabytes of video files, HD video files, or hard disk WLAN copies with dozens of gigabytes of hard drives, unless you are patient or impatient, so 802.11b, like a 10 m wired network, is not applicable to copying large-capacity Local Area Network files.

Because 802.11a is a mainstream non-market consumer, we will not introduce it
() specifies the size of the buffer to be described by the allocated MDL. If the length is less than 4 kb,Then the MDL mapped to it only describes a locked physical page;If the length is an integer multiple of 4 kb, the MDL mapped to it describes the corresponding number of physical pages (through the PFN array following the MDL)For Windows Server 2003, Windows XP, and Windows 2000,The maximum buffer length (in bytes) supported by this routine is:PAGE_SIZE * (65535-sizeof (MDL)/sizeof (ULONG_PT

The hardware on the x86 platform supports two-level page tables. models above the Intel Pentium pro support PAE and three-level page tables, so that the maximum addressing capacity of the system is 36 bits, that is, 64 GB of memory. However, when a system process is running, it uses a virtual address. on a

Preventive Measures to Prevent DNS attacks
DNS amplification attacks on the Internet is growing rapidly. This attack is a large variety of data packets that can generate a large number of fake communications for a target. How many fake communications are there? Several gigabytes per second, enough to prevent anyone from accessing the Internet.
Similar to the old-fashioned "smurf attacks" atta
Computer storage unit bit (BIT) (binary digits): stores a bit of binary, that is, 0 or 1, the smallest storage unit. Byte: eight binary bits are one byte (B), the most common unit. That is, 1B (byte bytes) = 8 bit computer storage units are generally represented by B, kb, MB, GB, TB, Pb, EB, ZB, Yb, BB, the relationship between them is: 1 kb (kilobyte kilobytes) = 1024b, 1 MB (megabyte megabytes referred to as "megabytes") = 1024kb, 1 GB (gigabyte gigabytes
If you configure SQL Server to contain only several gigabytes (GB) of data and do not undertake heavy read or write operations, you do not need to pay too much attention to disk I/O topics, and balance SQL server I/O activities between hard disks for optimal performance. However, to create a large SQL Server database that contains hundreds of gigabytes of data and/or undertakes heavy read and/or write activ

Table space used to hold InnoDB as a datasheet: More than one file may be involved; The maximum length of each tablespace file must be in bytes (B), megabytes (MB), or gigabytes (GB); The name of the tablespace file must be separated by semicolons; The last table space file can also take a Autoextend property and a maximum length (max:n). For example, ibdata1:1g; IBDATA2:1G:AUTOEXTEND:MAX:2G means
