+ PortThere are two types of IP addresses: ipV4 and Ipv6,ipv4 have 32-bit, IPv6 have 64-bitIPv4 is usually expressed as a point distribution, divided into 4 decimal digits, each corresponding to 8 bits, the range is 0-255 for example: 10.1.2.3Each IP address represents a connection between a host and the underlying communication channel, which is the network interface.If the address represents the building, then the port number represents the room, each port number is associated with an IP, the

less fun. But it rarely works. it is not object-oriented or has any defects. But object-oriented is not the basic atom of computer programming, they do not exist naturally as people imagine. Using object-oriented to solve the problem without a threshold will make the code bloated and over-Technical. However, many people insist on persistently using objects to solve all the problems. This is terrible beca

The software is divided into two parts. One is the 128-bit virtual computer simulator that supports both English and Chinese instructions in the csys instruction set. One is based on this kind of computer in the compilation of the Chinese and English environment. There are also some gadgets.Welcome to use the software.This software includes the Chinese assembly language compiler software. is a cross-assembl

6.00 is an entry-level course for mit cs. It is intended for people with little programming basics. I learned it once before and now I want to learn Python again. The first lesson mainly introduces some basic computer knowledge, which is simple but clear in logic and covers many important questions. 1. Declarative Knowledge vs Imperative Knowledge Declarative style: first, declare some rules, similar to he

the shortcomings of your dependency remarks. (4) Some rules, multiple interfaces, one line 2. Naming rules: This is to cope with the interview. I changed my job three times and interviewed some questions about the basic naming error. install it. A. Pascal method: for example, namespace, class, and method, each word must start with an uppercase letter: Class classname {} B. CAMEL: the first letter of the local variable and parameter must not be capitalized. Other first letters must be capitaliz

pseudocode to solve the problem first. 4. Code Running Efficiency Although the computer performance has improved a lot, the complexity of the problem has increased faster. Therefore, we need to improve the code running efficiency. We have two learning objectives: First, we need to understand efficiency in two dimensions: time and space. Space: memory usage Time: the running time of the program. The simplest way to judge the time is to run the pr
