Article Title: Common Ext3 file systems in Linux server operating systems. Linux is a technology channel of the IT lab in China. Some basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source Ext3 file systems

When using Javascript to implement interaction between the client and the server, you sometimes need to judge the operating system to achieve compatibility under different operating systems. For example, we have a website, in Windows XP, the browsing effect is good, but in Ubuntu, due to many different features, it may cause slight differences in browsing, and ev

Introduction to operating systems, operating system concepts A computer system can receive and store information according to human requirements. It can process and provide the required results. The results (output information) depend on the received information (input information) and corresponding processing methods. 1. Learning Process: I used to learn some re

File systems are typically implemented in a hierarchical structure: file management, directory management, and Disk Management file control blocks (BLOCK,FCB) are the only data structures that the operating system establishes for each file and contains all the file attributes. The FCB is usually pooled and organized together to form a file directory with two directory entries, each describing subdirectories

What is the difference between 32-bit and 64-bit computer operating systems ?, 32-bit Operating System When using a computer, we often look at the number of digits in the system first. Although many users know the number of digits in the system, what is the difference between 32-bit and 64-bit? In fact, this problem is very simple. The difference between 64-bit

For windows systems, the version is not determined here. If necessary, you can continue to judge the version after determining windows. The java version needs to be considered. The version is different and the results are different. The code below: 1. enumeration type: EPlatform [java]/*** platform * @ author isea533 */public enum EPlatform {Any ("any"), Linux ("Linux "), mac_ OS ("Mac OS"), Mac_ OS _X ("Mac OS x"), Windows ("Windows"), OS2 ("OS/2"),

Operating system knowledge-threads, operating systems-threadsThread A thread is also called a mini process. Threads are lighter and easier to create than processes. It is easier to switch. If a large number of intensive computing and IO operations exist. Multiple Threads are allowed to overlap these activities. Example. When we use a text processing software to

new language based on the B language, and he took the second letter of Bcpl as the name of the language, which is the C language At the beginning of 1973, the main body of the C language was completed, and Thompson and Ritchie eagerly began using it to completely rewrite the now-famous Unix operating system 1.2 Minix Because of changes in GE's policy, after Version 7 Unix was launched, new terms of use were released, the UNIX source

the terminal to the system to answer.The main goal of time-sharing system: The timeliness of user response, that is, the user is not waiting for the processing time of each command too long. Time-sharing system can accept dozens of or even hundreds of users, because of limited memory space, often using a swap (also known as Exchange) method of storage. Will not "turn" of the job into the disk, once the "turn", and then put it into memory, and the time slice, and then put the job back to disk (c

Distribution and desktopThe desktop options for distributions are one of the main ways to attract you to become their users.You might ask, "Wait a minute, you mean the desktop option?" Yes, Linux offers a variety of desktop environments, or shells called graphics classes, which are "cool" to extremely clean and minimalist. Unlike those operating systems that normally only provide a single graphical shell (i

-state, which is different from the data bus. The number of digits of the address bus determines the amount of memory space that can be directly addressed by the CPU, for example, the address bus of 8-bit microcomputer is 16 bits, the address bus of the 2^16=64kb,16 bit is 20 bits and the addressable space is 2^20=1MB. Generally speaking, if address bus select、read is n bit, the addressable space is 2^n byte. Control bus: used to transmit control signals and timing signals. Control signal, some
