What are the roles of a client and server and how do they interact over the network?

What are the Roles of computer in a network client server and peer?

The server supplies the information or access point and the peer is the computer requesting the information

Can a client act both as a client and server in a client and server network?

Yes, it can if the client is offering resources to others. It is important to note, however, that the client still is using client software and is not considered to be a server even if offering resources to others. That is, its role may change temporarily but it is still running client OS software.

The differences between peer to peer network and client server network?

With client to server, many people are downloading data from one central location - a one to many relationship. With peer to peer, many people are downloading data from many locations - a many to many relationship.

How are networks classified?

Network architectures are sometimes classified into two broad categories:· client-server architectures,· peer-to-peer architectures.In the client-server architectural model, a system is decomposed into client and server processors or processes. Servers provide computational resources (or services), which clients consume. Typically a server provides services to many clients. It is also common for clients to consume services from multiple services. Stated otherwise, there is generally a 1:M relationship between a server and its clients, and it is sometimes the case that there is a 1:M relationship between a client and the servers that it uses. The client-server architectural model supports the separation of functionality based on the service concept.Client-server architectures are commonly organized into layers referred to as "tiers".Tiered Architectures· Two-tier architectures. The system architecture consists of a data server layer and an application client layer. Data access computation is associated with the data server layer, and the user interface is associated with the client application layer. If most of the application logic is associated with the client application logic, it is sometimes referred to as a "fat client." If it is associated with the data access server, the application client layer is sometimes referred to as a "thin client." · Three-tier architecture. The system architecture consists of data server layer, an application server layer and a client application layer. The application server layer facilitates the separation of application logic from presentation, and promotes distributed processing.· Multi-tier architecture. The system architecture is a superset of a three-tier architecture, and includes additional layers for data and/or application servers.Peer-to-Peer ArchitecturesIn a peer-to-peer architecture model, a system is decomposed into computational nodes that have equivalent capabilities and responsibilities. This division is in contrast to a client-server architectural model, where client and server nodes are divided into server and client roles. An example of a peer-to-peer architecture is a system of intelligent agents that collaborate to collect, filter, and correlate information.Sometimes layered ("tiered") and peer-to-peer architectures are combined, where the nodes in particular layers are in peer-to-peer relationships. For example, a multi-tiered architecture might include an enterprise management layer, consisting of peer nodes for such things as network management, event management, database management, Web sever management, and workload balancing.

What is client-server?

The computer requesting information is called a CLIENT. The computer responding to the request is called a SERVER. Data transfer from a client to as server is reffered to as an upload. EX. When you want to enter the game. Ur the client waiting for the server to get you in Data transfer from a server to a client is reffered to as a download. EX. When you download stuff from Limewire or Utorrent. Your the server waiting for the client to give you the song or movie.

What are server roles?

A server role is a set of software programs that, when they are installed and properly configured, lets a computer perform a specific function for multiple users or other computers within a network. Generally, roles share the following characteristics.

Client and server operating system?

Basically the difference is how it's intended to be used. For instance, a client OS is optimized to give higher priority to client programs such as games, word processors, internet browsers, etc where a server would be optimized to run processes that the client systems would connect to and get information from such as email server programs, web server programs, databases, etc. However, there are a lot of similarities between the two and it is possible for a client OS to act as a server for some functions and vice versa.

What is the primary function of a file server on a client server network?

Holding users files.

What roles does a server play on the network?

The purpose of a server for a network is to provide a communications between the Internet and your computer (in other words it serves as a way to allow others outside of your home network to communicate with your computer)

What is the advantages of client server networking over centralized server?

The advantages of client server approaches particularly centralized services are as follows. · All data is stored on the servers, which generally have far greater security controls than most clients. · Servers can better control access and resources, to guarantee that only those clients with the appropriate permissions may access and change data. · Since data storage is centralized, updates to that data are far easier to administer in comparison to a Peer-to-peer model. In the end, data updates may need to be distributed and applied to each peer in the network, which is time-consuming as there can be thousands or even millions of peers. · It functions with multiple different clients of different capabilities. · Enables the roles and responsibilities of a computing system to be distributed among several independent computers that are known to each other only through a network. This creates an additional advantage to this architecture; greater ease of maintenance. For example, it is possible to replace, repair, upgrade, or even relocate a server while its clients remain both unaware and unaffected by that change. · Server hardware is designed to serve requests from clients quickly and redundancy and back-up, data can be stored in redundant ways making for quick restore in case of problems and more flexibility, new technology can be easily integrated into the system and interoperability, all components work together, and ease of use; server can be accessed remotely and across multiple platforms. · It is possible to remove or add clients without affecting the operation of the network and without the need for major modification. · Since the client and server component namely the user interface and database management are separated in the design of client-server model it eases the effort of database administrator and also developers. This is because developers can concentrate on user application alone. Also for example if a user interface change occurs the system can be changed with little effort by making changes only in the client side without making server component changes. · Performance is also increased without much effort. For example if a organization decides to go for a system for server side to increase performance this can be done without affecting the user application because client component of client-server model need not be disturbed in this case. · If we are using database server, we can use an automatic scheduler to back-up our database without having to exclude users from the database.
