Analysis of hardware route forwarding principles-early morning supplementBecause it was so sleepy last night, my eyes were spent while explaining the problem, and my mind was also short-circuited. When I got up in the morning and found my family still asleep, I wanted to continue talking about what I didn't say last night.My explanation diagram shows my hardware forwarding schematic again: Please note tha

The firewall can be divided into software firewall and hardware firewall as well as chip-level firewall if it is divided from the soft and hardware form of firewall. 　The first type: Software firewalls A software firewall runs on a specific computer that requires the support of a client's pre-installed computer operating system, which is generally the gateway to the entire network. Commonly known as "Pers

 I. DIRECTFB INTRODUCTION DIRECTFB is a lightweight graphics library that provides hardware graphics acceleration, input device processing, and abstraction, which integrates support for semi-transparent windows and multi-layer display on Linuxframebuffer drives. It is a layer that uses software to encapsulate graphics algorithms that are not supported by the current hardware to accomplish

according to Microsoft's official statement, the Windows XP system that accompanies us for many years will be officially "laid off" on April 8 this year, and no longer enjoy Microsoft's official support services. After the news, many of the loyalists of the XP system were terrified, fearing that there would be no security for official support services, and worried that if XP was used instead of Windows7 or WINDOWS8, it would make them "bleed". A comprehensive upgrade of the original

The most common work of hardware designers is to test hardware by writing code. These 10 C language techniques (C language is still a common choice) can help designers avoid some defects caused by fundamental errors and cause maintenance problems. In order to successfully launch a product, the software development process itself needs to experience countless practical risks and obstacles. The last thing an

Hardware environment for game music production Text/figure: Xiaoxu game music production room (www.game1234567.com) Game music design also belongs to the major category of music production. Some of the required hardware and software environments are not much different from those of professional music production rooms. Some commonly used hardware devices in t

The following are some of my experiences and feelings based on my experience in circuit design and Debugging Over the past 10 years. Let's just call it "circuit schematic design review specifications, the excerpt is for your reference only.1) understand the design requirements in detail and clarify the functional modules and performance indicators of the circuit from the requirements.2) Formulate the overall design scheme based on the functional and performance requirements, and select the CPU.

Zabbix enterprise application server hardware information monitoring Now we will introduce the Zabbix monitoring server hardware information. Because our company's servers use dell (our company is a mobile game, and all servers are dell), the server models include r410, r420, r710, and r720, the system includes CentOS 5.x, centos 6.x, RedHat 5.x, redhat 6.x, Ubuntu 12.04, and ubuntu 12.04.4.

Linux system time is sometimes not synchronized with hardware time Linux clock is divided into system clock and real time clock (RTC. The system clock is the current Linux kernel clock, and the hardware clock is the battery-powered clock on the motherboard. This hardware clock can be set in the BIOS. When Linux is started, the

With the rapid development of computer and IT technology, computer networks have become a very popular topic, which is closely related to almost every employee of the company) plan, set up, run, upgrade, and maintain, and publish and run to the enterprise website (including web, ftp, Email, and other services; from network security management to database management, storage management, network and personnel management, from network equipment to server and workstation (PC) operation management; f

First, the answer is no, the kernel interrupt number can be inconsistent with the hardware interrupt number, but this is a boring problem. Practical value is small. However, it can cause the consideration of the relationship between the kernel software interrupt number and the hardware interrupt number. the relationship between the two I think can be from the initialization and distribution of interrupts to

In the server hardware monitoring, the current industry is mainly based on the following two kinds: 1, the server comes with tools, such as HP's Hpacucli,dell OMSA, etc. 2. Intelligent Platform Management interface (IPMI, full name intelligent Platform Management Interface) Based on the above two kinds, through the Nagios, Zabbix or self-research operation and maintenance platform, such as the package, to carry out early warning operations. As the ser
