Explain about different networking operating system.

There are 3 different operating system.

                1. Client server operating system.

                2. Peer to peer operating system.

                3. Hybrid operating system.

 

1.Client server operating system Or Server based network:-

                Server based are defined by the presence of  dedicated

                server on a network that provide security and resources

                to the network.Server have many roles.

                                Server based network divide processig tasks

                between clients and server.client requests services such

                as file storage and printing and server deliver them.server

                computers typically more powerful than client computers

                or they are optimized to function as server.

                                In windows 2000 server based networks are

                organized into what are called active directory domains.

                Domains are collection of networks and client that share

                security information Special server called domain controllers

                domain security and login permission computer users can

                not access the resources of servers in a domain untill a

                domain controller has authenticated them

 

***.Advantage of server based networks:-

                --Storage central security.

                --Control file storage,Which allows all user to work from the same

                   set of data and provides easy backup of critical data.

                --Ability of server to pool available hardware and software ,lowering

                   overall costs.

                --Ability to share expensive equipment such as laser printers and

                   mass storage.

                --Optimized dedicated servers,Which are faster than peers at sharing

                   network resources.

                --Less intrusive security since a single password allows access to

                   all shared resources on the network.

                --Freeing of users from the task of managing the sharing of resources

                --Easy manageability of a large number of users.

                --Central organization,Which keeps  data from gatting lost among

                   computers.

 

***.Disadvantages:-

                --Expensive dedicated hardware.

                --Expensive network operating system and clint licenses.

                --A dedicated network adminstactor usually requierd.

 

2.Peer networks Or Peer to peer operating system:-

                Peer networks  are defined by a lack of central control over the network.

                There are no servers.In peer networks users simply shared disk space

                and resources such as printers and faxes.

                                Peer networks are organized into workgroups. workgroups have

                very little security control.There is no central login process.If you have

                logged into one peer on the network you will be to able to use any resources

                on the network that are not controlled by a specific password.

                                Access to individuals resources can be controlled if the user

                who shared the resources requires a password to access it,Because

                there is no central security,you will have to know the individual password

                for each secured shared resources you wish to access.This can be

                quite inconvenient.

                                Peers are also not optimized to share resources,Generally

                when a numbers of users are accessing resources on a peer, The

                users of that peer will notice significantly degraded performance.

                peers also generally have licensing limitations that prevent more than

                a samll number of users from simutaneously accessing resources.

 

***.Advantages:-

                --No extra investment in server hardware or software requird.

                --Easy setup.

                --Little network administration required.

                --Ability of users to control resources sharing.

                --No reliance on other computers for their operation.

                --Lower cost for small network.

 

***.Disadavantage:-

                --Additional load on computer because of resource sharing.

                --Inability of peers to handle as many networks connections as servers.

                --Lack of central organization,which can make data hard to find.

                --No central pointer of storage for file archiving.

                --Requirement that users administer their own computers.

                --Weak and intrusive security.

                --Lack of central managemant,Whic makes large peer networks difficult

                   to work with.

 

3.Hybrid network:-

                Hybrid networks have all 3 types of computer operating on them and

                generally  have active directory domain and work groups.This means

                that while most shared resources are located on servers,network users

                still have access to any resources being shared by peers in your working

                group.It also means network users do not have to log on the domain

                controller to access workgroup resources being  shared by peers.

 

***.Advantage:-

                --The advantage of server based networking.

                --Many of advantage of peer based networking.

                --Ability of users and network administrators to control security

                   based on the importance of the shared resource.

***.Disadvantage:-

                --Hybrid computing shares the disadvantage of server based networking.
