Computer Networks : Computers are connected generally in the same physical location, using different styles e.g. Token ring, Star, Serial connection, etc. Also called as LAN, Local Area Nerwork. U will find it in a library, small offices, in the same building, computer labs, cyber cafe's etc, etc. or computer network can be set up in your home also ...
Distrubuted Systems : Also can be considered as a type of computer network but in a much large scale. Generally called as WAN, or Wide Area Network. Different computers are connected at different physical locations across cities, states, etc. Using distributed systems, various computer programs can be run or executed remotely irrespective of physical locations, so as to use the more meomory and processing power of other computers.
"systems connected on a network" only says that the computers CAN exchange information. a "distributed system" implies that the computers are sharing information to accomplish a purpose, for example, to provide for a program or application where parts of it run on different computers. An example of a distributed system is one where the database runs on one computer, the accounting software that uses the database runs on another computer, and the user who wants to enter data into the system runs on a third computer. Computers that are merely on the same network together may not have all the software pieces in place to achieve this kind of cooperation.
Distributed Systems:
The set of autonomous computers that are interconnected through a software usually known as middleware.It is a paradigm presented to user
we can say
"A software layer above network that connects different computer is termed as distributed systems.
Computer Networks:
The set of computers that are connected physically to each other is called computer networks.
There is no presence of middleware or any other software the original system are connected with each other.
The internet refers to the web that is able to be accessed by anyone, anywhere. However, a distributed system is a software system, and just refers to those components on a networked connection.
In this context, a distributed system is often a peer to peer (p2p) type system in which many hosts/clients communicate directly with each other. Think of a web where all of the participating devices connect to many of the other devices. An example is bittorrent where chunks of files are shared directly between connected computers.
In a client and server model, all of the hosts/clients communicate with a central server. Think of a hub and spoke where the participating devices around the edge all connect to the central hub. An example is a website, hosted on a server and accessed by many computers directly.
The difference between the two is that a network could be defined as a group of locally connected computers (Eg: Computers connected in an office buliding); whereas, An internetwork is a collection of individual networks, connected by intermediate networking devices, that functions as a single large network
clustered system: systems having many computers with shared storage and linked by a lan or network.distributed system:systems having many computers connected by a network and there is no shared storage.Distributed computing is computing done on computers connected by a network. Clusters are one type of distributed computing. MPPs are another. Grid computing is a third.
On a computer network, operating systems communicate with each other. In a distributed operating system, a single OS is communicating with itself across multiple machines.
Whether or not a network cable is connected to your computer.
1. How might a distributed database designed for a local area network differ from one designed for a wide area network?
Group of devices connected together forms a Network & structure (design) in which they interconnect is called Topology.
A distributed computing system requires each machine attached to the network to has specific software allowing them to talk to each other. A distributed virtual systems allows the machines on a network to talk to each other without the use of central software.
The computer term 'mesh topology' is where a group of computers are connected to a network interconnecting with each other, thereby allowing the transmission to be distributed between all the connected computers.
It is what... DHCP is designed to automatically distributed IP addresses to connected to the same network devices.
We know a database is one that stores data related to each other. A network database is just like network database only difference between them is, in network database records are connected by means of a link.
A distributed computer system consists of multiple software components that are on multiple computers, but run as a single system. The computers that are in a distributed system can be physically close together and connected by a local network, or they can be geographically distant and connected by a wide area network. A distributed system can consist of any number of possible configurations, such as mainframes, personal computers, workstations, minicomputers, and so on. The goal of distributed computing is to make such a network work as a single computer.
A clustered system is a group of interconnected computers working together as a single system to provide high availability and scalability, while a distributed system is a collection of independent computers that appear to users as a single coherent system, typically spread across multiple locations. In a clustered system, nodes are usually physically close to each other and tightly connected, while in a distributed system, nodes can be geographically dispersed and connected through a network.
