 four-point communications realized
 LAN communication between the workstation program development generally through four ways: The first is through the transformation of the existing communication network software. However, this transformation must be based on understanding of the software, otherwise difficult to ensure that does not affect the modified overall network performance, even cause unreliable system operation, and modified the quality of communication is not necessarily ideal. The second is to use Novell's network protocol network itself IPX / SPX to achieve, due to too much trouble to develop this method, Sony PCGA BP2NX Battery using not much. The third is through function calls to implement NetBIOS, NetBIOS is a PC LAN communication interface standard, widely used in a variety of computer networks, making it the basis for the design and application development, portability, good. It does not depend in any network hardware, is a range of network hardware and user interface protocol between applications. The communication principle is: two workstations to communicate the name of the establishment of a virtual circuit through, and then to the appropriate send or receive virtual circuit number information, so that through the virtual circuit between two stations on the other communications. workstation using NetBIOS dell latitude d820 battery to achieve real-time communication between the functions are relatively strong, relatively easy programming, so widely. The fourth is through TCP / IP protocol to achieve. Below we will discuss in detail the implementation of various technologies. (a) based on IPX / SPX implementation technology the IPX / SPX protocol can not support communication between multiple, so little of this.dell latitude d420 battery

in NetBIOS NetBIOS programming interface is the Network Basic Input / Output System the abbreviation, that is, network basic input output system, it is an application interface. NetBIOS user can invoke a variety of functions, without the need related to a variety of the lowest level of communication protocols, enabling the data source and data destination information exchange between. 1 NetBIOS Overview NetBIOS is the IBM first introduced in 1984. It can support a variety of well-known communication protocols such as TCP / IP, MAP / TOP, XNS, IEEE and OSI, etc., not only for DOS environment, but also can be used in UNIX, OS / 2, WINDOWS environment. dell latitude 131l battery

ISO / OSI seven layer protocol and OSI Reference Model seven layer reference model structure shown in Figure 1. The model is a logical combination of features to stratification, the layer is established on the basis of the next layer, the lower layer to provide a higher level service requests, while the lower layer to a higher level of service. The so-called open system is posed by this model is the interconnection network is open to each other, so as to facilitate the interconnection of networks around the world. OSI model layers are defined as follows: acer um08b41 battery
 the network application layer network applications to run in this layer.
 that help the user perform actions such as the text layer between the transmission running other tasks.
 session layer management connection between the lower and the user is UNI.
 transport layer checks the integrity of network data, adjusted when necessary data packet to the correct position. set packet header to the data set is sent to the destination.
 network layer packet in the form, select the path to send data. each group to reach their destinations through the two lower. acer um08b31 battery
 data link layer management network interface input / output. on the raw data is organized and prosecutors.
 physical layer defined in the network cable and wiring used in the rules and agreements. include routine contact processing and transmission of norms, also defines the use of cable types and connectors. (b) IEEE 802 LAN standard reference IEEE 802 standards compliance model ISO / OSI reference model principle, to solve a minimum two ---- the physical layer and data link layer functions and the interface with the network layer service, high-level functions related to Internet interconnection, IEEE 802 LAN Reference Model and ISO / OSI reference model shown in Figure 3 the corresponding relationship. 1 IEEE 802 standard documents five IEEE (Institute of Electical and Electronics Engincers), the electrical and Electronics Engineers, it is a acer um08a74 battery learned professional nature. It is two layers of OSI model physical layer and the lower data link layer protocol standard for a lot of research. IEEE 802 standards designed to create different vendors compatibility between devices, so as to use the network of users and equipment manufacturers to pay a smaller price in the post will be able to successfully communicate between these devices. The Institute, after years of research and revision, in 1984 the official LAN standards of the five proposed standards document. acer um08a73 battery

 ISO reference model from the discussion of the course clearly understand the physical layer, data link layer and network layer together to accomplish the transfer function of the packets, so the physical layer, data link layer is indispensable. but taking into account the characteristics of local area network, IEEE 802 was amended 对 OSI reference model. IEEE 802 data link layer sub- into two sub-layers, namely, the logical link sublayer (LLC) and media access control sublayer (MAC). in the MAC sub-layer, CSMA / CD, token bus (Token Bus), Token Ring (Token Ring), such as several medium access control. in the data link layer interface with the network layer service access point set (SAP). dell latitude d830 battery
 Network Communications and the instance (a) the process of communication
 process, referring to a program execution. the process of communication between the processes that share resources and mutual exchange of information data transmission mode. OSI transport layer provides communication services for the process.
 Method for Communication Process : Sony VAIO PCG NV Battery
 1) to establish the connection between the dismantling process and
 2) information transfer and control (b) point to point communication from the OSI Reference Model
 Application layer point of view, can be considered network is composed of workstations and servers, but the transport layer and network layer point of view, workstations and servers is not essentially different, they are connected to a machine on the network, the network can be used address or name instead. the communication between them is the so-called point to point communication, also known as peer communication. on the LAN, two stations can be little communication means a direct dialogue without going through the file server transfer. Sony Vaio PCG 6C1N Battery
 in the Windows 95 built-in networking features such as point to point on, you can easily share a small working group between the text and the printer instead of paper server. Windows 95 than Windows for workgroup3.11 one of the most unique feature: it has a significantly improved safety program, each user can be at the user level that the resource level and can share files and printers and other resources. Sony VAIO FR series Battery
 in Windows 95, the point-to-peer network has more flexibility because it can be multi-user Netware (running on IPX / SPX or TCP / IP agreement) between the point peer connection. Windows 95 Windows for workgroup clients can do everything, you can do better.
