...Peer-to-Peer and Client/Server Networks Darsheen Smith Strayer University Peer-to-Peer and Client/Server Networks A network is a group of computers and other devices, such as a printer, that are connected by some type of transmission media (i.e. fiber optic cables or radio waves) (Dean, 2010, p.2). Originally “sneakernet” was the only means of electronic source sharing. It involved the transfer of electronic information by physically couriering removable media, such as floppy disks, from one computer to the next (Wikipedia, 2011, para 1). With the advancement of computer technology so is the modernization of computer networking. Analysis There are two types of networks, peer-to-peer and client/server networks. Both have the capability to communicate with other computers on the network. They also have the capability to protect files from unauthorized users. There are also distinct differences between the two types of networks. In a peer-to-peer network every computer can communicate directly with every other computer. No computer has more authority than another. A Typical peer-to-peer network consists of two or more personal computers (Dean, 2010, p.3). In contrast, a client/server network consists of a central computer, called a server, which is designed to permit communication and information sharing between computers, known as clients, on the network. The clients do not share their resources directly with each other...

...What's the difference between client/server and peer-to-peer networks? There’s quite a bit, although most of the differences are in two areas – security and cost. Beyond that, your consideration for what you need is largely dependent on budget and the size of your organization. So, what’s the difference? A peer-to-peer network has no central server. Every workstation on the network shares files equally with everyone else on the network. This also means there is no authentication of users and no central storage. This model is considered a decentralized form of networking. Conversely, the client/server network provides a central pool of data and resources, with user profiles established with localized restriction on which data can be accessed. This model is commonly referred to as a centralized form of networking. Both are good! There’s an old saying, ‘wisdom is what works’. Well, the same is true for your network. Peer-to-peer networks are great for use in homes or in small businesses where employees interact regularly and share all information and files. They don’t cost much to setup, nor are they difficult to manage. The downside is there’s almost no security (pretty much controlled at an individual ‘share’ level). Once you get more than 8-10 workstations connected, there would likely be an impact to performance and management since each station functions as both client and server at the same time. As each employee manages the sharing of their workstation...

...Peer-to-Peer and Client/server Networks Professor: Karen Lederer Trevor Kale 4/16/2011 We shall discuess the difference between Peer-to-Peer networks and the Client/Server networks. First we need to describe how each one operates in order to view the differences between both. First we will describe a Peer-to-Peer network. In the Peer-to-Peer network every computer can communicate directly with every other computer.(2009, Dean, Pg.3) Because of this setup no one computer has more authority then another one on the network. Each person on the network can set their access and restrictions for other users to their computer. These configurations are simple to configure and due to the simplisity they do not require a great technical expertise. They also tend to be cheaper due to lack of need of equipment to establish this network. Some disadvantages consist of not being flexible, that is as they grow they become more difficult to handle. Security on these networks is very lacking due to ease of access of unauthorized access. They are also not very practical due to the lack of centralized resources requires a user to have their terminal on in order to access their resources. That is the basics of a Peer-to-Peer network setup, next we move on to the Client/Server model. In a Client/Server network a centralized computer known as a server facilitates communication between other computers on the network known as clients. For a computer to function as a server they must be running...

...Pair Cable The current network model that is being used by your company today is the peer to peer model. This model is an ideal selection for a company or organization when there are very few computers. Since your organization currently has 20 Windows peer to peer client computers I would like for you to consider moving towards the client server network modelOnce a peer-to-peer network grows beyond 10 computers, it will likely begin to suffer from performance and from administrative problems (Posey, 2000) In the client server network model network hosts have specific roles which are assigned to them. There are certain host that are assigned as servers, which will provide network resources to the workstations. Unlike the current peer to peer model that is supported in your organization today in which everyone workstation has the same or similar operating systems. There are several benefits for your organization to consider to transitioning to client server network model. One of the major benefits of the client server network model is scalability. Since we know the potential for this organization to double in size over the next two years scalability is a key factor. It’s very easy to expand the size of your network with client server model because it will be easy to just add on workstation. Everything is centralized to the server. This server will be the centralized platform for all the workstations. Another major benefit of this client server model is increased security...

...In a computer network evaluation it is important to cover various areas to determine which are satisfactory and which are in need of improvement. The following 15 evaluations will be used to access the current state of the network: 1. Evaluation of Client Computer Hardware In the evaluation of client computer hardware, this evaluation seeks to identify all client computer assets owned by the company. All laptops and desktops owned by the company should be made available as needed in order for the evaluation to be as accurate as possible. It will be necessary to perform a review of all client computers that connect to the company assets. These machines will be analyzed for speed, performance, and reliability. I will look for variations in hardware manufacturers. Depending on the circumstance, it can result in better TCO (Total Cost of Ownership) if client computers are limited to one or two manufacturers. In addition, machines that are broken, out of warranty, or outdated will be recommended for repair or replacement. 1. 2. Evaluation of Client Computer Software In the evaluation of client computer software, I will seek to identify all software that is installed on client computers and being used in the workplace. This evaluation can be performed using software metering in software such as Microsoft System Center Configuration Manager, if installed. If not installed, this information will be collected manually by viewing the installed software on each machine. ...

...Network Assignment #2 1. Compare Peer-to-Peer against Client server Networks. Discuss (briefly) the differences using the following factors: a. Security: Peer-to-Peer does not provide the security available on a client/server network but a client/server has its resources centralized which mean resources and data security are controlled through the server. b. Complexity: Peer-to-Peer only required two computers connected together however client/server required special software to communicate between server and client. c. Operating Systems requirements: Peer-to-Peer required an operating system such as Windows XP or Appleshare to establish a network communication, however for client/server special software such as Novell Netware or Windows 2000 server must be installed on the client and server devices. d. Scalability: Peer-to-Peer e. Redundancy / backup: 2. Define the following: a. Router: is a device that connects two networks - frequently over large distances. b. Hub: is a network device that connects multiple computers on a LAN so they can communicate with one another, the rest of the network. c. Switch: is a small hardware device that joins multiple computers together within one LAN. Technically, network switches operate at layer two Data Link Layer of the OSI Model. d.

...The first alternative will have a special tool developed in C++ that clients will download onto their computers to run. The tool will communicate with the DRUB server to select data to analyze. – This alternative would be client based architecture. The client gives the command to the server. 2. Alternative Two: The second alternative will have the C++ program running on the server; the client will use his or her browser to interact with the server. – This alternative would be two tier thin client server architecture. This requires a web browser, a server and application layer. B) Outline the pros and cons of the two alternatives and make a recommendation to Fred about which is better. Alternative One – Client Based Architecture. Pros: 1. This is an affordable alternative since microcomputers are cheaper than mainframes and it does not take long periods to implement. 2. On a client based architecture, varying hardware manufacturers can cross function. Cons: 1. All data on the server must travel to the client for processing; this can lead to an overload of the circuits on the network since far more data than is needed is usually transmitted. Alternative Two – Two Tier Thin Client Server Architecture Pros: 1. There is a balance of processing since both the server and the client do the same processing making the system an efficient one. 2. Cross functioning is able on client server architecture, so that different software and hardware from different...

...the sale of items from the cash registers with additional features for interpreting the data. It uses a client-server model with a connected database to allow multiple stores and warehouses to be connected. This allows for later expansion while still supporting the targeted small businesses. The core features and final framework should be completed within 2 weeks, leaving 5 weeks to implement additional features and testing. 1. Operational Concepts The Inventory Management System is a real-time inventory database capable of connecting multiple stores. This can be used to track the inventory of a single store, or to manage the distribution of stock between several branches of a larger franchise. However, the system merely records sales and restocking data and provides notification of low stock at any location through email at a specified interval. The goal is to reduce the strain of tracking rather than to handle all store maintenance. Further features may include the ability to generate reports of sales, but again the interpretation is left to the management. In addition, since theft does occasionally occur, the system provides solutions for confirming the store inventory and for correcting stock quantities. 2. System Requirements The Inventory Management System uses a web-based interface to display inventory data to the stock manager client. The product will use of open-source software primarily due to cost of implementation. A JSP (JavaServer...

The files need to be accessed by all 10 users, and each user must have different security rights. What kind of network would you install? How would the pieces and components of this network relate to each other? Define each component. You'd want a client-server environment using Active Directory possibly with a file server. A. Server to handle logon/authentication. Most likely Windows Server, with Active Directory. B. File server; a computer attached to a network that has the primary purpose of providing a location for shared disk access C. The administrator will create security groups based on departments. D. The administrator will create a Shared Drive directory structure where EACH folder represents a department: This way as you add your 5 more employees, you simply add them to the necessary security group which automatically grants them access to the corresponding shared drive. 2. You are the network administrator for a company that has a peer-to-peer network. How would the pieces and components of this network relate to each other? Define all the components of this type of network. In general, office and home P2P networks operate over Ethernet and employ a hub-and-spoke topology.

...access file servers If the user can access the file server using an IP address but not a name, then the most likely reason for failure to connect is a name resolution problem. Name resolution can fail for NetBIOS or DNS host names. If the client operating system is NetBIOS dependent, the VPN clients should be assigned a WINS server address by the VPN server. If the client operating system uses DNS preferentially, VPN clients should be assigned an internal DNS server that can resolve internal network host names. When using DNS to resolve internal network host names for VPN clients, make sure that these clients are able to correctly resolve unqualified fully qualified domain names used on the corporate network. This problem is seen most often when non-domain computers attempt to use DNS to resolve server names on the internal network behind the VPN server. 2. Users can't access anything on the corporate network Sometimes users will be able to connect to the remote access VPN server but are unable to connect to any resources on the corporate network. They are unable to resolve host names and unable to even ping resources on the corporate network. The most common reason for this problem is that users are connected to a network on the same network ID as the corporate network located behind the VPN server. For example, the user is connected to a hotel broadband network and is assigned a private IP address on network ID 10.0.0.0/24. If the corporate network is also on...

...Running head: CLIENT SERVER PROS AND CONS 1 Client Server Pros and Cons Henry Ford POS355 October 6, 2014 Mr. Kernan CLIENT SERVER PROS AND CONS 2 Client Server Pros and Cons Computer Networking has a vast amount of attributes. These attributes allow a system to not only function in a specific way but they also add definition to the system which in turn creates a specific identity. One of the identities of a Network is a Client/Server Network. The term "client server" defines a network system where computers known as servers are used. The Servers create central management. This form of management is used to access the network. Each network has a plethora of segments that are used for resources and data storage. These Network applications are used in Commercial applications more so than anywhere else. Since there are a variety of Network configurations, the end user has to determine which one of the specific Network features they want and also to consider the advantages and disadvantages of each system. Even though the Client/ Network architecture is the most desirable for most commercial businesses, there are certain disadvantages in this system. “The reason that client/server computing is still growing in popularity is because top management believes that it will save them money, and end-users believe that it will solve many of their computing problems.” (Windsor, 2011) Client/Server Definition: This type of computing provides the necessary comingling of personal computers...

...CLIENT SERVER PROGRAMMING AND MULTIMEDIA Introduction Client/server describes the relationship between two computer programs in which one program, the client, makes a service request from another program, the server, which fulfills the request. Although the client/server idea can be used by programs within a single computer, it is a more important idea in a network. In a network, the client/server model provides a convenient way to interconnect programs that are distributed efficiently across different locations. Computer transactions using the client/server model are very common. For example, to check your bank account from your computer, a client program in your computer forwards your request to a server program at the bank. That program may in turn forward the request to its own client program that sends a request to a database server at another bank computer to retrieve your account balance. The balance is returned back to the bank data client, which in turn serves it back to the client in your personal computer, which displays the information for you. The client/server model has become one of the central ideas of network computing. Most business applications being written today use the client/server model. So does the Internet's main program, TCP/IP. In marketing, the term has been used to distinguish distributed computing by smaller dispersed computers from the "monolithic" centralized computing of mainframe computers. But this distinction has largely disappeared...
