5) Distributed System -
• A distributed system is a collecting of physical,separate,hetrogeneous computer system that are network to provide users with access to various resources.
• Access to a share resources increase computation speed,functionality,data availibility and reliability.
• Distributed system depends on network for their functionality.
• Network vary by the protocol used distance beween nodes.
• Network are characterized based on distance between there nodes.
I. Lan connect computer within a room,building,campus.
II. Man connect computer within a cities.
III. Wan connect computer within many cities or countries.
IV. Pan connect device in several feet distance like- bluetooth connectivity.
• The media to carry network include copper wire,fiber optic and wireless communication – satellite,microwave dishes,radio transmission.
• Distributed operating system manage a group of computer that could be linked and made to communicate with each other.
Advantage of distributed system –
• Resource sharing facility at each site
• Reliability if one site fail in a distributed system the remaining site can continue operate.
• Reduction of the load on the host computers.
• Reduction of delay in data processing .
• Better service to the client
• Ex. Plana & Locus.
