hardware and software requirements for linux operating system

devices do special processing in Linux. Linux's network system is mainly based on the BSD UNIX socket mechanism. There is a specific data structure (SK_BUFF) defined between the system and the driver to carry out the transfer of information. The system supports the caching of sending data and receiving data, provides

and block devices communicate.However, character devices and block devices do not have significant boundaries, such as for Flash devices, which conform to the features of block devices, but we can still use it as a character device to access.2, Linux device driver and the whole hardware and software relationship1, in addition to network devices, character device

manipulate the CPU? If there is a major error, it is not the CPU first to deal with the more important is to deal with things just not finished.When the CPU is handling things, there are other important requests to interrupt the operation, which we call interrupts. Interrupts are available in two types with soft interrupts and hard interrupts. There are hardware interrupts that are being processed by the work we call a hard interrupt, and there is

2-1 Linux operating system and common commands, 2-1 Linux Edit it based on the beginner videos 2-1 and 2-2 of Marco's linux 1. GUI and CLI GUI: Graphic User Interface CLI: Command Line Interface Note: In Windows, DLL: Dynamic Link Library is a Library file. In fact, there is

In the process of using Linux, you may encounter system clock and hardware clock inconsistency, that is, Date,hwclock--show see the clock is inconsistent. The Linux clock is divided into system clocks (systems Clock) and hardware

password, anyone can log into the system, making it unsafe. You also need to be very careful when updating your software. Because if the Linux kernel is updated, bootloader is likely to be corrupted. This method is not flexible compared to a system installed on a hard disk. Because the kernel that bootloader needs to

. Generally, server applications require the highest memory consumption. Of course this is a digress. 　　 We will first discuss how to optimize your system with the same hardware configuration (the same server, without upgrading the hardware. 　　 As a system administrator, I think that first, we need to clarify the point

As a desktop operating system, Linux's man-machine interface is not flattering. However, as a network operating system, its ease of use (for NOS) and high performance are difficult to find its right. Of course, this does not mean that the operation is very simple, but that if you can master some skills, both

also supports many other network protocols, including the code of the AppleTalk protocol, which allows Linux units to communicate freely with Macintosh machines. The Novell network protocol, that is, the Network Packet Exchange (IPX ), group message Exchange (SPX) and NetWare Core Protocol (NCP); new version of IP protocol IPv6 and some other less famous protocols. The last aspect of compatibility is hardware
