Swap Area Linux

This article is written by http://www.aliyun.com/zixun/aggregation/13357.html ">azure CAT team Piyush Ranjan (MSFT). As infrastructure services (virtual machines and virtual networks) are recently officially released on Windows Azure, more and more enterprise workloads are migrating to the public cloud to take advantage of cloud profitability, scale, and speed. I recently participated in one of the enterprise work negative ...

Linux can boot Linux from a floppy disk or hard drive. When booting Linux from a floppy disk, the boot sector contains code that reads only the first hundreds of blocks of data (of course, depending on the kernel size) to a predetermined memory location. 　　On a Linux boot floppy, there is no system and the kernel has contiguous sectors because it simplifies the boot process. After the floppy disk Boots Linux Linux is loaded, it initializes the hardware and device drivers and then runs Init. Init can start other processes to Http://www.aliyun ....

Modern computers use virtual memory to have more memory. Virtual memory can also help to accomplish more things. Part of the disk space can be used as an extended http://www.aliyun.com/zixun/aggregation/17967.html "> Memory space, the swap area." In a Linux system, it is possible to swap files, swap partitions, or join the two or no swap partitions. Swap partitions are a little faster than swapping files, and Linux systems ...

Slackware is a Linux distribution made by Patrick Volkerding. Slackware went along with the other distributions (Red Hat, http://www.aliyun.com/zixun/aggregation/33836.html ">debian, Gentoo, SuSE, Mandriva, Ubuntu and so on) different paths, it is trying to become "Unix-style" Linux distribution ...

Now we're going to introduce a command "mount" that is very important in Linux. This command is used to mount each partition on the hard disk to a folder in the root partition, or it can be called an installation file system. Some Linux distributions default to partitions other than the root partition, such as "RedHat 9". There is, of course, an exception to a swap partition called "swap." Also, some Linux distributions can automatically mount all Windows partitions after the system is installed, such as "Red Flag 5.0". In our study ...

A hard disk has up to four primary partitions, or three primary partitions + one extended partition (contains n logical partitions). Linux can be installed in primary or logical partitions. In general, only the points/and swap two areas is sufficient, in addition, it is recommended to filesystem separate partitions, after reloading will not have to reset a lot of things. Swap is the swap partition, if the memory <=256, please set to 512MB in the partition, memory >=512MB to a 512MB is enough (if you want to sleep, I am afraid, or >= memory comparison insurance). ...

Recently read some Linux command line articles, in the system information to learn a lot of commands. Think of a previously written article in fact, Linux so much easier to find these system information to view the command can also be summed up a small thing to come. # CAT/PROC/MTRR View Mtrrs Memory type range Registers # uhttp://www.aliyun.com/zixun/aggregation/11696.html >name-r view current kernel ...
