What are the contents of computer or computer network professional papers in the examination of public institutions? I. Concept of Computer Network A computer network is a computer system with independent working ability distributed in different geographical areas, which realizes resource sharing and data communication through communication equipment and lines with perfect network software. As can be seen from the definition, there are three problems involved: (1) At least two computers are interconnected. (2) Communication equipment and media. (3) Network software, communication protocol and NOS The network equipment made by each manufacturer is different. In order to enable them to communicate with each other, they must abide by certain rules, that is, protocol representation. Two, the composition of the computer network consists of hardware system and software system. 1, network hardware connection equipment service appliance workstation (1) server: it is the core of the whole network, which not only manages the network, but also serves the network users. According to different functions, it can be divided into file server, print server, communication server and backup server. It is actually a well-configured computer. (2) Workstation: Computers connected to network servers can share resources. (3) Peripheral devices: devices used to connect servers and workstations. Play the role of communication. 2. Network software: comprehensively manage hardware to realize communication and resource sharing. (1) Network operating system (2) Network communication software III. Functions of computer networks The functions of computer networks are mainly manifested in the following aspects: (1) data communication; (2) real-time centralized control and management of distributed objects. In various information management systems, it is necessary to manage the database centrally, such as various online information decision-making systems and the application of C/S and B/S structures. 3) It can establish resource sharing function files, printing, data and application software sharing services, as well as communication services and fax services. (4) Load balancing and distributed processing functions Under the management of distributed operating system, a big task is broken down into small tasks and distributed to different computers on the Internet for execution. (5) Integrate information service functions, such as e-mail, BBS, e-commerce, virtual community, university, remote login and online meeting. Fourth, the development of computer networks The development of computer networks has reached the fourth generation. In the early days, computers were highly concentrated and placed in a big house. Later, time-sharing and batch processing appeared, and the first generation of computer networks appeared in the 1950s. 1, the first generation of computer network is composed of a single computer connected to multiple terminals, such as the American aircraft booking system. 2. The second generation computer network The second generation computer network is a network in which a plurality of host computers are interconnected by communication lines. Such host computers all have autonomous processing ability, and there is no master-slave relationship between them. At present, a network in which a plurality of host computers are interconnected is usually called a computer network. The typical representative is ARPA network, which is mainly composed of four main nodes. It is also the Zou style of our current Internet development. There is a special communication processor in ARPA network, which is responsible for the interconnection of lines. This device is called (Interface Information Processor IMP). When the host wants to send a message, it only needs to send it to its associated IMP, and then IMP is responsible for finding the other party's IMP and sending it out. IMP uses the store-and-forward method and sends it when the line is idle. In this way, ARPA network has formed a two-level subnet structure. Communication sub-resources and resource subnets. 3. The third generation computer network, the international standardized network in the ARPA network era, although the network is divided into communication subnet and resource subnet. However, the inconsistency of system structure and protocol standards between networks limits the development of computer networks. ISO, the international organization for standardization, issued "Open System Interconnection", which makes the interaction between networks possible. All communication devices, software and protocols follow the OSI model. 4. The fourth generation computer network The current network is already in the Internet era, and it is developing in the direction of interconnection, high speed and broadband. Various applications on the Internet are also increasingly rich, such as virtual universities, virtual communities, e-commerce, video-on-demand systems and so on. It has had an important impact on our lives. V. Classification of Computer Networks There are many standards for the classification of computer networks, such as topology, transmission media, application protocols, etc. However, these standards can only reflect the characteristics of a certain aspect of the network, and the classification standard that best reflects the essential characteristics of network technology is distribution distance, which can be divided into local area network, metropolitan area network, wide area network and Internet. 1. LAN: A minicomputer of several meters-10 km was developed after the popularization of a large number of microcomputers. It is easy to configure and has a high speed of 4 Mbps-2 Gbps. Located in a building or a unit, there is no pathfinding problem, excluding the network layer. 2. MAN: 10 km- 100 km LAN is interconnected to a city, adopting IEEE802.6 standard, 50 kbps- 100 kbps, and located in a city. 3. Wide area network: also known as long-distance network, hundreds to thousands of kilometers. It developed earlier, leased private lines and connected with lines through IMP to form a network structure, which solved the routing problems of CHINANET, CHINAPAC and CHINADDN in the Ministry of Posts and Telecommunications at the rate of 9.6 kbps-45 Mbps. 4. Internet: It is not a specific network technology, but an advanced technology that unifies different physical network technologies according to certain protocols. Commonly used network communication protocol 1. The concept of agreement. Because of the protocol, different workstations and servers in the network can transmit data. With the development of network, different developers have developed different communication methods. In order to make communication successful and reliable, all hosts in the network must use the same language, without dialects. Therefore, strict standards must be formulated to define every bit of every word in every data packet between hosts. These standards come from the efforts of many organizations for a common communication method (i.e. protocol). All these make communication easier. Definition of protocol-some conventions that must be met to realize communication in computer networks. Can be implemented in hardware and software. OSI (Open Systems Interconnection) was proposed by ISO (International Organization for Standardization) in 1978. It defines the communication protocol of computer network architecture as seven layers: physical layer, data link layer, network layer, transport layer, session layer, presentation layer and application layer. Many protocols have been developed, but only a few remain. There are many reasons for eliminating these agreements-poor design, poor implementation or lack of support. Protocols that have stood the test of time have become effective communication methods. The three most common LAN protocols today are NETBE UI from Microsoft, IPX/SPX from NOVELL and TCP/IP across platforms. Second, NETBEUI protocol NETBEUI is a non-routing protocol developed for IBM, which is used to carry NETBIOS communication. It is designed for workgroups with several to hundreds of computers. Advantages: high efficiency, high speed, low memory cost and easy implementation. NETBEUI lacks routing and network layer addressing functions, because it does not need additional network addresses and network layer headers and tails, so it is fast and effective, and is suitable for small workgroup environments with only a single network or the whole environment connected. Disadvantages: NETBEUI will never become the main protocol of enterprise network, because it does not support routing. Generally speaking, bridging NETBEUI networks rarely exceeds 200 hosts. Thirdly, IPX/SPX protocol IPX is a protocol group used by NOVELL for NETWARE client/server, which avoids the weakness of NETBEUI. However, it also brings new and different weaknesses. IPX has a complete routing function and can be used in large enterprise networks. It contains a 32-bit network address, allowing multiple routing networks in an environment. This protocol is used in NOVELL network. Not applicable to the network of WIN98 operating system. 4.TCP/ IP protocol Each network protocol has its own advantages, but only TCP/IP allows complete connection. TCP/ IP was developed by MIT and some commercial organizations for the US Department of Defense in 1960s. Even if most networks are destroyed by nuclear attacks, TCP/ IP can still maintain effective communication. ARPANET was developed based on protocol, and later developed into a communication medium between scientists and engineers. TCP/IP has both scalability and reliability requirements. Unfortunately, it sacrifices speed and efficiency (but the development of TCP/ IP is funded by * * *). After the popularity of Inter, people began to discover the powerful functions of the World Wide Web. The universality of Inter is the reason why TCP/IP is still used today. Usually, without realizing it, users install TCP/ IP stack on their own PC, which makes network protocol the most widely used protocol in the world. V. How to choose the network communication protocol The choice of network communication protocol affects the speed and performance of the network. When choosing, we should consider the scale, compatibility, convenience and speed of management of the network. If the network of 1 and WINDOWS series is a small WINDOWS NT server/workstation network, NETBEUI protocol should be selected, which is fast; If it is a large Internet connection, it is necessary to install TCP/IP. If the workstation of WIN95 only has TCP/IP installed, it cannot join the WINDOWS NT domain. 2. If NOVELL network clients want to access NOVELL network, they should join IPX/SPX protocol 3 and WINDOWS. If NOVELL network hybrid network wants to connect to the Internet, IPX/SPX protocol, NETBEUI protocol and TCP/IP protocol must be added. 6.IP address 1. IP address: The Internet is interconnected by different physical networks, and the communication between computers in different networks must have corresponding address identifiers, which are called IP addresses. IP address provides a unified address format, which consists of 32 bits. Because binary is inconvenient to use, users use "dotted decimal" to represent it. The IP address uniquely identifies the network where the host is located and the location number in the network. IP address is divided into two parts: network number and host number. For example: IP address: 192. 168.0. 1.2. According to the size of the network, the commonly used IP addresses are divided into the following three categories: a: This kind of address is characterized by starting with 0, the first byte indicates the network number, and the second, third and fourth bytes indicate the host number in the network. The number of networks is small, which can represent at most 126 network numbers, and each network can have at most 167772 14 hosts. 0 * * * * * * * * * * * * * * * L-1260-2550-2551-254b: This address is characterized by starting with l0, and the first one is. 10 * * * * * * * * * * * * * * * * * * * * * * 19 1 0-255 1. 1 10 * * * * * * * * * * * * * * * * * * * * * 192-2330-2550-255 1-254d。 Other knowledge of computer network. IP address: 1, network number can't start with 127, and the first byte can't be all zeros or all L.2. Host number can't be all zeros or all 1. So there are no IP addresses of 255.255.255.255 and 0.0.0. 3. 127.0.0. 1 is the IP address of this machine and cannot be used as the IP address of the host on the network. 2. Subnet mask 1. Function: In order to quickly determine which part of an IP address represents the network number and which part represents the host number, and to judge whether two IP addresses belong to the same network, the concept of subnet mask came into being. The subnet mask is given according to the format of the IP address. 2. The default subnet mask of class A, B and C IP addresses is as follows: A: 255. O.O.0B: 255.255.0.OC: 255.255.0 3。 Calculation of subnet mask: The method to judge the network number and host number of an IP address by subnet mask is to AND the IP address with the corresponding subnet mask. For example, 10.68.89. 1 is a class A IP address, then the default subnet mask is 255.0.0, o, which are all converted into binary and the network number is 10. Another example is that 202.30. 152.3 and 202.30. 152.80 are class C IP addresses, and the default subnet mask is 255.255.255.0. After AND operation, it is concluded that the two hosts are in the same network. 4. Subnet division: Another function of subnet mask is to divide subnets. In practical application, we often encounter the problem of insufficient number of networks, and it is necessary to divide a certain type of network into multiple subnets. The method adopted is to divide some binary bits in the identification part of the host number to identify the subnet. Step: (1) Convert the number of subnets to the m power of 2. If you want to divide it into 8 subnets, 8= 2 to the third power. If it is 6, take the big one to the third power of 2. (2) M is converted into decimal after occupying the m bits of the host address in the high order. For example, if M= 3 is 1 1 100000, it is converted to decimal 224. (3) If it is a Class C network, the subnet mask is 255.255.255.224. If it is a Class B network, the subnet mask is 255.255.224.0. If it is a class A network, the subnet mask is 255.224.0.0. 3. Domain name system and DNS server: 1. People prefer to use strings with specific meanings to identify computers on the Internet. Therefore, in the Internet, users can name their computers in various ways, which may lead to the opportunity of renaming on the Internet. For example, all hosts providing services are named, all hosts providing e-MAIL services are named mail, and so on. , which cannot uniquely identify the host location of the Internet. In order to avoid duplication, the Internet Society adopted the method of adding a suffix to the host name, called domain name, to identify the regional location of the host. The domain name was legally obtained through application. In this way, hosts on the Internet can be uniquely identified by "host names". Domain name ". For example,. tongji.edij.cn is the host name, named by the server administrator, and tongji.edij.cn is the domain name, which can be legally used by the server administrator. Domain names have certain regional affiliation, and the general structure is "regional name, organization name and country name", in which Tongji University stands for Tongji University, EDU stands for national educational institutions and CN stands for China. Tongji.edu.cn represents the host computer of Tongji University, an educational institution in China. Inter Association stipulates that there are seven types of organization domain names, namely: COM: commercial organizations. EDU: Organization of educational institutions. INT: international organization. Government: * * organization. MIL: Military organization. NET: network organization. 0RG: Non-profit organization. Geographical countries Different countries have different names: China, the United States, Japan, France, Australia, Canada and the United Kingdom. I hope it will help lz.
