Modern society, the network has become the same as water, electricity as our indispensable daily needs, can say that the network everywhere. As a user, you only need to learn how to use the network, and as a computer professional students, a programmer is necessary to understand the principles. Therefore, this chapter will mainly introduce some basic definitions of computer networks, network architecture, e

In my personal summary, computer professionals, especially engineers, need to master the following knowledge and technology: 1. More and Better mathematical skills Undoubtedly, the foundation of logical thinking may be a natural fit for some people, but after a long period of mathematical thinking training, logical thinking must be a good foundation! Degree of requirement: the first stage is suffic

matrix mode.Summary The computer simulates binary numbers 1 and 0 through the level of electronic components. Any information stored in the computer must appear in binary digital mode before processing can be completed, the original binary digital sequence is called the information machine code. binary digital can perform computation perfectly only by completing the code. In order to be able to describe mo

With the rapid development of electronic technology and the rapid improvement of people's living standard, the popularization and update of computer is getting faster and bigger. Integration, more and more digital, fault type and fault phenomenon more and more difficult to grasp, as the motherboard chip-level maintenance personnel, is to continuously improve their professional knowledge and maintenance skil

What is the role of the Computer Host Gateway? Suppose your name is Tom. You live in a big courtyard. Your neighbors have many friends. At the door, there is another Uncle Li who looks at the door. Uncle Li is your gateway. When you want to play with a friend in the yard, as long as you shout out his name in the yard, he will respond to you when he hears it and runs out to play with you. However, you are not allowed to go out of the door. If you want

only be done by a computer assembler software translated into machine language program. People can barely understand assembly language. People commonly used language is a higher level of high-level language, such as C,java and so on. The programs written in these languages are generally able to run on a variety of computers, but must be pre-written by a software called compiler or interpreter to a specific machine language program, the person who wri

51cto College, in the soft exam preparation season, I specially sorted out the "Network Management knowledge points of the 2014 computer soft exam" to help schools pass smoothly!

message segment (that is, the syn=1 segment) cannot carry data, but consumes a sequence number. At this point, the TCP client process enters the syn-sent (synchronous sent) state.b After receiving the connection request message segment, agree to establish a connection, then send acknowledgement to a. In the confirmation message section should be the SYN bit and the ACK bit 1, the confirmation number is ack=x+1, but also for their own selection of an initial sequence number seq=y. Please note th

, I especially like my name before the OJ examination. I will practice all the exercises as soon as I have time. However, interest and ability sometimes complement each other. When I work hard to improve my strength, I am more and more interested in the C language, I think I prefer C language. Everything needs to be created by myself. Looking back at my college life over the past two years, I have become more and more aware that a person who wants to succeed must have a deep foundation. A

the instruction format to form the valid address of the operand. O) bus multiplexing, as the name implies is a bus to achieve a variety of functions. The common bus multiplexing method is bus time-sharing, which refers to the use of the same signal line on the bus at different times to transmit different signals, for example, address bus and data bus share a set of signal lines. The purpose of this method is to reduce the number of buses and improve the utilization of bus. P

corresponding signal to the peripheral; 5. After the DMA sends out the signal, it realizes the data exchange between memory and peripheral, or memory and memory. 6, Dmac after the execution of external tasks, through the CPU to send hold signal, REVOKE the DMA request. the above is a full DMA mode of data exchange. input and output technology can be said to realize the important channel of human-computer interaction, people and computers for dia

Because of being a science man, I particularly like to be involved in other areas of knowledge. And for me, the computer is very attractive-especially programming language design, know a "foreign language" is how important. Freshman exposure to include basic knowledge of computers, C language, this new semester also began to contact LabVIEW, plus their own choice

address. The client browser initiates an HTTP session to 220.161.27.48, and then encapsulates the packet via TCP, which is entered into the network layer.2) in the client's transport layer, the HTTP session request into the message segment, add the source and destination port, such as the server use 80 port to listen to the client's request, the client by the system randomly select a port such as 5000, and the server to exchange, the server to return the corresponding request to the client's 50

, the main thing is to find the routing table to determine how to reach the server, during the period may pass through a number of routers, these are done by the router, not too much description, is simply to find the route table to reach the server through that path.4) The link layer of the client, the packet is sent through the link layer to the router, through the neighbor protocol to find the MAC address of the given IP address, and then send the ARP request to find the destination address,

the destination.3) The client's network layer is not related to the application layer or the transport layer of things, the main thing is to find the routing table to determine how to reach the server, during the period may pass through a number of routers, these are done by the router, not too much description, is simply to find the route table to reach the server through that path.4) The link layer of the client, the packet is sent through the link layer to the router, through the neighbor pr
