Enter a positive integer. when outputting, output the number itself, followed by a comma, and then output the factorial and equal signs of the numbers, The calcul

The score of the Master of Engineering at Jiaotong University is over. Let's celebrate it first. However, it is not a few days before the review. This is a professional course for the university. I will review a course every day. Start with the computer composition principle. Focus The history of computer develop

Computer Network ReviewComputer network This course is this semester, "Software Technology Foundation" one of the course content, accounted for only 20 hours of teaching, scaled score is also about 30 points. But the knowledge of this course is too much, too miscellaneous, and often closely related to life, such as: why the router with the time is 192.168.0.1? Why is the intranet within the campus inaccessible outside the campus? Why the Internet is s

collision;The main points of the CSMA/CD agreement are summarized as follows:① ready to send: The adapter obtains a packet from the network layer, plus the Ethernet header and tail, which make up the Ethernet frame, into the adapter's cache, but before sending it, it must first detect the channel;② Detection channel: If the channel is detected busy, it should be constantly detected, waiting for the channel to become idle. If the channel is detected to be idle and the channel remains idle within

Today to review: in-depth understanding of computer systems, writing technical articles in the belly of the ink other in too little, just write me read this book sentiment, long ago bought this book, but the revised version. At that time to look at that called a uncomfortable ah, the root of the heavenly book almost. This time to participate in the training, the teacher also mentioned that the book came, an

environment variable, in order to be able to compile the source files anywhere.Java_home: In order to change the JDK path, do not affect the path variable separately for the JDK to create a new variable, to prevent the misuse of other system variables.Class_path: When you execute a class file, look for the scope of the class file's location, and the purpose of classpath is to tell the Java execution Environment which directories can find the classes or packages you need to execute the Java prog

Computer hardware can actually be more easily divided into CPU + memory +io devices. The three of them are through a bus to exchange data, and you know in the three CPU speed of the fastest, memory second, IO device third, to make the three coordination of communication requires a certain control. 2. our CPU has its own local bus, the same memory, the local bus through the motherboard of the South Bridge chip link together to communicate. North Brid

Interview, the interviewer if you want to test the computer network learning how, how to say also need to ask the TCP three handshake process it? So, I began to review the computer network April 24, intermittent review for 3 days. ISP: Internet services Provider Internet service Provider Eg: Chinese telecom, China Un

any host must send the ARP Request packet on the network as long as there is one communication, which makes the traffic on the network increase greatly;6.ARP sets the lifetime of each mapped address item that is stored in the cache, and removes it from the cache whenever it exceeds the time to live; In order to avoid hardware changes after the device hardware change, but not to communicate properly '7.ARP is to solve the problem of mapping the IP address of the host or router on the same LAN or

ping uses an ICMP echo request and a loopback reply message; Ping is an example of the use of the network layer ICMP directly by the application layer;(2) Another very useful application is traceroute: used to track a packet from the source to the end of the path; Traceroute sends a series of IP datagrams from the source host to the destination, and the datagram encapsulates the undelivered UDP user data; The time-to-live TTL of the first datagram is set to , the second one is set to 2, and so

Lead: Microsoft founder and chairman of the board of directors Bill Gates will resign from the position of Microsoft's chief software architect at the end of this month, officially withdraw from the company's daily management affairs and devote himself to philanthropy. Gates's departure meant the end of an era. A few days ago, Michael Miller, former editor of PC Magazine, interviewed gates. The two reviewed the development history of the computer indu

Suddenly thought of the computer's complement, now use this topic to review the relevant knowledge pointsunsigned char ch =-1;int val = ch;The final value of Val is 255;Converted to binary,-1 Source: 1000 0001, anti-code: 1111 1110, negative numbers in the computer is in the form of complement, 1 of the complement: 1111 1111CH variable is unsigned, that is, the entire complement of bits are numeric digits,

Computer Network review: Topic 1. How does the Internet organize its connection structure?1. essential differences between early "networks" and modern networks:Early "network": Host-centricModern Network: group-based exchange network2. The network and the network are connected through routers to form a network with a wider coverage.3. computers connected to the Internet are both called hosts and end systems

-down hierarchical search;* * Common binary clues, this special structure of the tree, the IP address from the left to the right of the bit value determines the path from the root node-by-layer downward, and the path of the binary clues in the route table represents the various addresses;* * from the root node of the two forks the top-down depth is up to 32 layers, each layer corresponds to one of the IP addresses; the rule for an IP address to deposit two forks is simple: first detect the first
