What is the working mode of the network

It has two working modes, 1 is the Client Server mode ( Client /Server), referred to as the C/S mode

2 is the Peer to peer mode (Peer to peer), referred to as the p2p mode

Client Server mode, and Peer to Peer mode is also the two working modes of the local area network is popular at present.

C/S mode

Servers are high-performance computers and specialized equipment dedicated to providing services; clients are user computers. This is a form of network in which clients send requests to the server and obtain services, and multiple clients can *** enjoy the various resources provided by the server. This is the most commonly used, the most important type of network, not only for the same type of computer network, but also for different types of computer network. The security of this network is easy to ensure that the computer's rights, priorities are easy to control, monitoring is easy to achieve, network management, can be standardized; but the performance of this network depends largely on the performance of the server and the number of clients. Currently for this type of network there are many optimized performance servers, dedicated servers. Banks, securities companies are using this

p2p mode

peer-to-peer network does not require a server, each client can talk to other pairs of clients, *** enjoy each other's information resources and hardware resources, last night's computers are generally the same type. This network is flexible and convenient, but it is more difficult to achieve centralized management and monitoring, security is also low, more suitable for the department within the collaborative work of small

We all know that the network, it provides us with, is a service function, so the next thing I want to introduce the small knowledge of network services.

Network services

What are network services? Network services are the added features that users can get through a computer network, in terms of *** enjoyment of resources and data communication.

The most commonly used services are the following aspects:

File service: it refers to the network users can not only make their own workstations on the program data, but also can use the server or other workstations in the **** enjoy the program and data users can be used as a local disk, as the program and data therein for access.

Printing services: network workstations are generally no longer configured with a separate printer, the user needs to print output, the operating system will automatically send the output file to the network printer. For each file that needs to be printed, the network printer in the order of first-come-first-served will be stored in the print queue, and then processed, the user can view the print job. Pause or cancel print jobs in the print queue.

Messaging services: refers to the network can realize the mutual communication between users, between users to pass the text, images and sound indicated by the message, the most typical messaging services is e-mail, others, such as online chat, Internet telephony, short messages, webcasting, video conferencing, etc. are messaging services of the ordinary type is that they have been widely used.

Application services: is a service for network users to run software, that is, the workstation needs to perform a task, part or even all of which is completed by another computer on the network (known as the application server). Application servers allow computers on the network to **** enjoy each other's processing power to work together to complete a particular service.
