How The Implementation Of A Client Server

WAN(Wide Area Network)-Wan is 2 or more local area networks connected together.It is fairly expensive to set up but like the LAN it is very fast.There are many different ways of creating WANS”S like using VPN’s over the internet.A WAN is created when the users of a LAN frequently needs access to rescources of another

An operating system must support a wide variety of networking protocols in order to meet the needs of its users. The user will be able to identify and make sure that various systems and servers are running smoothly, also the user is will if the system is loaded or

Describe the data communication types used historically and the developments that have led to modern day Local Area Networks (LANs). Detail any emerging technologies and where you think data communications are likely to be in ten years’ time.

Routers and switches will be utilized to route network signals to all areas of this large network. Telephony systems will be introduced to serve the VOIP located at each location to assist with communication needs. Wireless technologies will also be needed to assist with mobility and other devices such as printers, laptops, fax machines, etc. Lastly, a physical firewall will be enforced at each location to protect the network from internal and external intruders.

Server state can be divided into two part : the stateful and stateless server. The stateful server is that when a client open a file the server gives that client an unique identifier and stores client’s information into its memory. Although this method can improve performance, however, stateful server is generally be avoided in distributed system. On the other hand, stateless server uses totally different mechanism that the server identifies the file information and client position in each request but save nothing into its memory. The advantage is that it is easier to use fault tolerance on stateless server.

I have learned many things in this class, things I never thought I were important. For example, the types of networks, I had never heard of MANs before. I knew what a LANs and WANs were but not the MANs. I now know MANs (Metropolitan Area Networks are large scale LANs. Another, thing gleaned from this class is Peer-to-Peer and Client/Server Networks. I found out that Peer to Peer networks are decentralized communication models where each station has the same ability to perform and any station can start a communication session. In the P2P network model each node functions as both a client and server. Whereas, a Client/Server Network is a program relationship where one program is the client and requests a service or resource from another program

When setting up a LAN the architecture that you decide to choose is important. There are several factors that are decided when choosing said architecture, some of these being network speeds, types of cables, and access control mechanisms like collision detection (Team, 2011). The most common on in today’s LANs is Ethernet. These can be either wireless, wired, or a hybrid of both.

As we all know, the growth of computer networks continues to rapidly grow. The digital revolution has changed the way we work and communicate almost beyond recognition. Provided that, foreseeing the changes and potential compatibility problems, in the mid nineteen eighties, the international standard organization (ISO) developed a networking reference model to standardize how network systems communicate with each other. It is a logical model for how network systems are supposed to communicate with each other. It breaks down the different components of the network communication and puts them into layers which reduce complexity. This reference model consists of seven layers: Application Layer, Presentation Layer, Session Layer, Transport Layer, Network Layer, Data Link Layer, and the Physical Layer. Each layer provides a service to the layer above it in the protocol specification and then communicates with the same layer’s software or hardware on other computers. It's important to realize, that these layers are separated into 2 sets: Transportation Set (Laters 1- 4) and Application Set (Layers 5 – 7). More importantly, the OSI model is 7 logical

6. Why is Ethernet technology more appealing to users than the rest of the LAN technologies?

A computer and a server are usually two unique and separate devices and each are customized to handle specific functions and purposes. For example a web server will not need any type of display or monitor and can be located anywhere. But when it comes to a data server or client, there is typically a need for some form of display monitor so information can be reviewed and tracked. It is not uncommon in some occurrences that a device can function both as a computer and a server for the same application. This also can hold true for a application act as a client to other server for various other

Client Server is a computer system where a central server provides data of networked workstations.

Ideally, each local office would integrate its computers with a LAN, so that all employees would be able to share information, and resources such as printers. In case there are multiple buildings in an office (like in the corporate office), each building would have its own LAN, and the LANs could be connected by a Backbone Network.

In terms of security, ease of access and speed Client/Server Network Model and Virtualization Network Model are the best. Virtualization is more complex when compared to Client/Server Model and the training and maintenance costs are high when compared to Client/Server Network Model. Peer to Peer Network Model is the least expensive and stable network model but does not offer security and fast access to the shared resources. In comparison the Client/Server Network Model and Virtualization Network Model provide high security and fast access. Recovery and backup is also possible with Client/Server and Virtualization Models, whereas recovery and backup is not

The ability to send and receive data efficiently is the most important objective of networking computers.

All the computers, in the logically and physically networks have to follow the same rules known as Protocols such as TCP/IP, IPX/SPX and NETBEUI etc. Today, there are many computer networking technologies such as LAN, MAN, WAN, WLAN, ISDN, ATM, Frame Relay, X.25, Bluetooth,
