computer case thumbscrews

don't know whether you believe it or not. The popular dvcd on the market is the most dangerous enemy of the optical drive, because it is much closer to the standard point of the general optical drive, the optical drive is just as difficult as a myopia to read the small text, maybe one day it will be "blind ".Keyboard-do not use moisture, dust, or dragCurrently, most keyboards use plastic film switches, which are composed of three-line plastic films. The middle part is a insulating film with hol

use the three-wire power users, users can make a ground, a one-foot-long iron wire into the more humid land, with wire to the wire and computer chassis metal plate connection. If the previous two methods do not have the user, do not have to pay attention to this leakage flow, because it does not cause danger to the human body, some users with a wire to the computer chassis and the home of the pipe connect

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

, they are widely used. For example, when we say normal body temperature is 98.6 (Fahrenheit), it does not need to be accurately expressed if the thermometer shows 98.6 degrees. It could actually be 98.5999473210643 degrees. This shows that 98.6 is sufficient for most applications.Another way to get a floating-point number is through division. 10 divided by 3 to get 3.333333 ..., is an infinite loop of small compress. The computer allocates only a fix

Construction algorithm: Case Study 1 (counter control repetition)To demonstrate how to develop the algorithm, we have to solve the problem of the average grade of several class. Consider the following questions:There are 10 students in the class who take the quiz and can provide test scores (integer values from 0 to 100) to determine the average grade in the class.The average class grade equals the sum of the whole class divided by the number of class

Today, my colleague took a notebook and said that WiFi connections are normal, but they cannot access the Internet. If you change the Unit's WiFi and the phone's shared WiFi, the Internet is not accessible.First, I checked the IP address settings to check whether the IP address is specified. No.Then cancel IPv6. The fault persists.Check the IP address acquisition status. Everything is normal. You can get the address.It's strange. What's going on?Later I thought about whether it was the proxy ser
