GHOST Vulnerability (GHOST) affects a large number of Linux operating systems and their released versions (update and repair solutions) Security researchers recently revealed a critical security vulnerability named GHOST (GHOST), which allows attackers to remotely obtain the maximum control permissions of the operating system, affecting a large number of Linux

only tool. If we are only limited to using Linux to develop our own computer software industry, there is no future. The reason why Linux systems are favored by many vendors is that they provide low-cost, cost-effective, and even free development platforms for computer software vendors. But Linux is not perfect. InOne disadvantage of running Linux on an embedded system is that the Linux system needs to add real-time software modules to provide hard re

answers Third, the operation speed is different. 64-bit CPU GPRs (general-purpose registers, universal Register) data width of 64 bits, 64-bit instruction set can run 64-bit data instruction, that is, the processor can extract 64 bit data at a time (as long as two instructions, a single extraction of 8 bytes of data), The 32-bit (requiring four instructions, one fetch of 4 bytes of data) increased by one time, and in theory, the performance would increase by 1 time times. Computer Four, the a

guaranteed2 High priority priority scheduling algorithm2.1 Types of priority scheduling algorithmsThe highest priority priority (FPF) scheduling algorithm is introduced in order to take care of the urgent operation, so that it gets preferential treatment after entering the system. This algorithm is often used in batch processing system, as a job scheduling algorithm, also as a process scheduling algorithm in a variety of operating

1. Kernel-level thread: The switch is controlled by the kernel, and when the thread switches, the user state is converted to the kernel state. The switch is completed to return the user state from the kernel state, and the SMP can be used to make use of the multi-core CPU. This is the case with Windows threads.2. User-level thread core switching by the user-state program to control the kernel switch, do not need the core interference, less in and out of the kernel state consumption, but not a go

Although there are many techniques for server virtualization, the methods for running two or more operating systems using simulated hardware such as VMware, Hyper-V, and XenServer are similar. In this way, we can run two or more environments in a virtual machine on a physical server. In the server operating system, this virtual machine is the same as the physical

Multiple linux instances, we need to modify this file. So how can we modify it? In general, windows is automatically loaded to grub. conf. Open grub. conf to view the settings of windows. Sometimes the system may suddenly fail to attract windwows. We need to make the following changes. Title DOSRootnoverify hd0, 0)Chainloader + 1 Change Title ## here, WinXP is a required title. You can use another name.Root hd0, 0)Chainloader + 1 In this way, the instance can be started. ◆ 5. How to add the gui
