+ 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

: Network Disk DownloadThe first revision of volume 3rd makes the most comprehensive study of the classical computer sorting and searching techniques. It expands the processing of data structures in volume 1th to take into account both the size database and the internal and external memory, and selects a well-tested computer method and makes quantitative analysis of its efficiency. The salient feature of vo

What is the difference between an algorithm and a program? The algorithm is a concept, the program is the concrete implementation of the algorithmThe computational thinking pattern means that everything can be seen as a mathematical problem involving numbers and formulas.Two things that any computer can do is calculate and save results.Memory: RamAlu (Arithmetic logic unit): Do some primitive operationControl unit: Track event flowStep: When reading a

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
