A few days ago, I saw a blog about my thinking. In addition, I have a slight feeling of learning clojure: In the blog we read, we asked the readers to divide the cows, grass, and fish into two types. We compared two different ways of thinking: 1 ). associated thinking: Divide cows and grasses into one type, because cows graze; 2 ). object thinking: It classifies cows and fish as one type, because both are animals. Later, when preparing to learn the

When I was in the operating system class today, the teacher mentioned: "The ACM Program Design Competition is only a group of senior students who are full and have nothing to do with organizing activities. As an undergraduate student, I want to find a good job, we still have to carefully learn Win32 programming and master various win32apis ". I have a negative attitude towards this point of view. As an acmer, I am very angry. Maybe in the third year of high school, I would like to agree with thi

To form a basic network, you need only one hub (hub) or one switch, several NICs, and dozens of-meter UTP lines to complete.In fact, such a simple network is the basic unit of a more complex network. By connecting these small, simple networks together, they form aMore complex local area networks (LANs).3.1 The simplest network650) this.width=650; "Src=" Http://s5.51cto.com/wyfs02/M02/82/1C/wKioL1dL8SuxD8-BAAGyseXLHG4802.jpg-wh_500x0-wm_3 "Title=" qq20160530154707.jpg "width=" 229 "height="-wmp_4

Hierarchical model of computer network:From bottom to top: Physical layer, link layer, network layer, Transport layer, application layerThe physical layer (connecting the computer in the form of optical cables, radio waves, etc.) specifies the electrical characteristics of the network, and transmits 0 and 1 of the electrical Signal Link Layer Ethernet Protocol (which specifies the interpretation of electric

needs to adjust the size of the sub-network.Note: In this way the subnet is divided into subnets, all 0 subnets, and all 1 subnets are available.CIDR (No-class inter-Domain routing protocol):The non-class inter-domain routing protocol allows multiple classes to be merged into a larger network, called a hyper-net.For example, the 192.24,8.0~192.24.15.0 these 8 have a class network, you can synthesize a network number of 192.24.8.0, the subnet mask is 255.255.248.0.CIDR can significantly reduce t

I use the computer than to learn the time to spend more time, here, some of their own experience posted to us. One: The source of information is very important, I learned every useful technology, is a high man or network know the name, and then find the relevant book information in the system of detailed learning.
