Unit 9 M1 compare the benefits and disadvantages of peer to peer networks and client/server networks Introduction In this task I will talk about the Peer to Peer networks systems and explain the benefits and disadvantages of them. Also I will talk about the Client server network. I will explain the advantages and disadvantages of them. Peer to Peer network systems Peer to peer networks are a kind of computer systems which are linked with each other through the internet. Files can be distributed straight amongst systems on networks with no central server required. That is to say that every computer on the P2P will turn into a file server and a client. For a computer to join a P2P, it would only need to connect to an internet and a P2P software. Examples of P2P software programmes are Kazaa, Morpheus and Limeware. These programmes are able to link to a P2P network and it enables a computer to gain entrance to over a thousand of different systems within the network. Advantages Disadvantages It enables easy file sharing as a robust P2P can share files very fast over huge distances. Every computer could be accessed by other users as it can have an impact on the performance of the computer. It includes reduced costs meaning that there is no need to spend money on a different computer for a P2P server. Files and Folders are impossible to be backed up centrally. It has a good adaptability meaning that P2P networks are able to include new clients without any difficulty. Files and other resources are not structured into a specific area. They are placed on separate computers and it could be hard to find if the computer’s user does not have a filling system. P2P is reliable and it can remain functional if the central server stops working. There is very few to zero security with the exception of permissions. There would no use of technicians because users make their policies as to files, they are allowed to share Make sure that viruses do not go through the network is the responsibility of every user. This means that it does not have means to defend itself against viruses.
Unit 9 Client-server network Client-server network is a circulated communication structure of network handling between services requesting, clients and Internet service providers. The client is created through an internet or the network. It is a network computing design to make email exchange and database access accessible. Protocols and other web technologies designed around the client server model include 4 protocols which are HTTP, DNS, SMTP and Telnet. Clients consist of browsers, chat applications and email software between others. Servers are made up of webs, databases, application and chat and email. A server is responsible for arranging majority of the processes and it is capable of placing data. A client would ask for definite data or processes. The server communicates process output towards the client. Occasionally, clients are capable of handling processing. However, they are needed server resources to complete. Advantages Disadvantages Every file is stored in a main location It costs more than a peer to peer network as you would need to pay for the start up cost. Network peripherals can be controlled centrally If the server is down or crashes, every computer that is linked to it will be unavailable for use. Backups and network security are manipulated in the centre. Professional staff such as a network manager would be required. Users are able to access data that is shared and centrally controlled. It anything contributes to network failure, there will be a lot of disruption. Every data stored has robust security control than majority of clients. As you expand the server, it will start slowing down as reason to the bit rate per second. Servers are able to handle the access and resources well to promise that only clients that have the right permission are able to modify and access data. If everyone attempts to do the similar thing, it will take long for the server perform tasks.
