In today's large network of enterprises, network security has always been a concern of managers, virus transmission and hacker intrusion has become the main threat of foreign attacks on corporate networks. At present only the virus or hacker's single means attacks the network to attack the phenomenon to be less and more, but is more uses many kinds of attack means the synthesis use. At present, the most prominent is the transmission characteristics of the virus and hacker attack characteristics
With the arrival of summer, room temperature significantly elevated, many friends of the computer began to appear due to poor heat caused by the blue screen crash and so on. For computer users, it is generally possible to clean the dust and the chassis plus the cooling fan to improve the computer's cooling capacity, personal advice to clean up the dust and add a cooling fan two-pronged approach. Now the question is, what about the power supply for the
The back line is in recent years in DIY assembly computer, more often heard, belong to the DIYer of professional terminology. In simple terms, the back line is for the computer chassis, as long as the chassis and power support to go back line, in the installed time, it can be internal wire to achieve the most streamlined and tidy, not only beautiful appearance, late maintenance is also convenient, and also
The two-wheel differential model of the robot chassis, is the most common robot chassis, such as sweeping robots, tracking cars and so on. As a moving part of a robot, it needs to realize two functions of input and output.
Input: Receive control instruction speed V and angular velocity w (v,w)-unit m/s RAD/S
Output: Robot relative posture X, y axis coordinates, angle th (x,y,th)--unit M M RAD

I do not know if you have ever encountered the case of computer chassis leakage, when you touch a part of the body of the computer chassis shell, an instant there is a clear feeling of electricity. This is a common in our lives a kind of chassis leakage phenomenon, that this is normal? What is the cause of leakage of computer
So, how do I get the motherboard jumper? In fact, it is very simple, we just have a reason to think, one by one, it is easy to connect. Generally speaking, the main board jumper on the needle mainly includes switch power switch, reset switch (coincidence), power light, hard drive lights, speakers, audio, USB interface, and so on, seemingly a lot, but one to, it is not difficult, the following detailed introduction.
How to connect the chassis
The Qianyi "Dragon ice five generations" 1U chassis adopts an innovative integrated design concept of "Chassis + radiator, A passive heat sink with a large heat dissipation area called "qianniu" is directly cooled by a powerful fan in the chassis, which greatly improves the air volume and heat sink area of the CPU cooling fan, it has produced epoch heat dissipati
Chassis generally include housings, brackets, panels on a variety of switches, indicators and so on. The shell is made of steel plate and plastic, and the hardness is high, which mainly protects the internal components of the chassis. The bracket is mainly used for fixing motherboards, power supplies and various drives.
There are many types of chassis
Chassis Width
Small chassis is still not the market mainstream
First chassis as a hardware-supporting, the internal space is naturally there is a certain demand, to the current market, ATX Architecture chassis occupy the mainstream position, the whole tower, small
The power supply is a variant of the Intel Standard ATX Chassis Architecture, which does not change much in the computer chassis, but moves the power supply position from the original rear corner to the rear corner. It has been a long time since the ATX chassis of the power supply has been placed in place. Especially in the past two years, the power supply
Although the radiation intensity of the computer is not big, but for the long-term use of the computer Office users, the harm is still relatively large, although a lot of chassis are very exaggerated to say that our chassis is absolutely radiation, this is just advertising rhetoric, today, the computer network editor to talk to you about how to understand how a certain brand of
Once we in the " computer Assembly Course " column for you to introduce a variety of computer assembly tutorials, rarely involved in a number of chassis cooling fan installation tutorials, for the recent netizen asked how to install the chassis fan, today's computer depth of the small compiled to share with you. For many general installed configuration, the chassis
The chassis now sold on the market, regardless of brand size, claimed to be able to prevent radiation. However, due to the different workmanship and materials, the radiation capacity of each chassis varies greatly. So what kind of chassis radiation capacity is stronger? Here are some ways to see and hand touch, to determine the radiation capacity of the
If the chassis noise is big, it will affect the mood, whether in learning or in the game. So what happens when the chassis is noisy? How do I reduce the noise of the chassis? Here's a look at the case for a little bit of noise reduction.
The source, the noise I produced
The noise generated by the computer is caused by the resonance of the
200 or so computer chassis to buy which good?
For DIY installed friends, when buying a chassis may exist such entanglements, too cheap to worry about, poor quality, and expensive and not willing to buy. In fact, the chassis equivalent to the skeleton of the computer, it will not affect the computer performance, but do not recommend to buy the following poor qual
In our DIY long "levy Machine" on the road, there has been the disaster of static electricity, I was deeply affected by static electricity, hard to explore, to find the way to eliminate static electricity, the following article on how I eliminate static electricity "suffering" experience, I hope to give you a little help.
Remember the computer just assembled back, the use is very normal, once accidentally touched the chassis rear panel (
1. How large is the radiation of the host?
Most people will care about the choice of LCD to avoid the large radiation of CRT monitors, in fact, many users do not notice that the chassis of the accessories (host) is also a small source of radiation. Some users will feel dizzy and so on after a long time using the computer, actually this and the host's radiation size and use is correct. For example, some users in order to give the host a better cooling
The Applicable type refers to the type of computer host to which the chassis product can be applied, and is generally divided into desktops and server/workstation enclosures. The most basic function of the Desktop chassis is the most common chassis, which is to install a variety of accessories from a computer host. In addition, also requires a good electromagn
First of all, I would like to consider the cost of the chassis, of course, the price of the chassis from hundreds of yuan to thousands of yuan have, so before choosing the chassis to determine the price of their own heart.
Consideration of the price of the computer chassis
The second thing to consider is the size of
The famous chassis manufacturer TT brought the armor (armor) series chassis after the shark chassis. what we bring to you today is the va8000swa chassis.
The chassis is made of all aluminum and has a tower structure with a very beautiful appearance.
