passage of time, X-window became more and more useful and more excellent. At present, each major Linux distribution, can be done well as desktop computer use.(2) Windows:Advantages: Good graphical interface, with a good integrated development environment, easy to operate.Cons: Not free software, using binary code, not easy to modify the operating system itself. The vulnerability is much higher. Compared wi

Operating System Concepts Learning Note 6 system callsSystem callssystem calls, usually written in C or C + +, may be provided as assembly-language instructions for the underlying tasks, such as requiring direct access to hardware.An example of a system call:To write a simple program that reads data from one file and c

memory. This table is called 文件分配表(File Allocation Table,FAT) .Advantages: Two disadvantages of solving the linked list above. For random Read and write, because in memory, even if it O(n) is acceptable. The data is stored 2的整数次幂 . Disadvantages: For 200GB the disk and 1KB size of the block, this table is required for 2亿项 each table entry 4字节 .The memory of this watch 600 is 800MB not very practical Therefore, it FAT is not suitable for large d

. Because my computer is X86 the Win7 operating system of the schema, the downloaded simics installation files are supported for installation under the WIN32 system. Simics can simulate different hardware architectures, allowing testers to perform a variety of tests without having to have a computer with a real hardware architecture.Simics is not an open-source

I. fat12 Fat12 is a file system used in the DOS era. It is still used on a floppy disk until now. After the fat12 floppy disk is formatted, it has two heads, each head has 80 cylinder (track), each cylinder has 18 sectors, and each sector has 512 bytes of space. Therefore, the total space of the standard floppy disk is: 2*80*18*512 = 1474560b = 1440 K = 1.44 m The structure of fat12 is as follows: 1. Boot Sector The reason why the

before remember This period of time is really too busy, there is a long time did not write a report, this time Pyos development is basically and half stagnant state, the first two days just built a pyos CVS (http://pyos.binghua.com), Hope has been the development can be a little more efficient a little ~ ~ ~ ：） Recently did not do anything, only completed a system call experiment, to get back to the bottom, I would still introduce my experiment.

The file system is part of the operating system and ultimately the purpose is to manage the files.The concept of creating files in the operating system is to make it easier for multiple processes to share some data, which is stored on disk. Multiple processes can be accessed
